Terms of Service

Version 1.19.0 — Last updated: October 7, 2026

These Terms of Service ("Terms") govern your use of MogTier ("the App"), operated by Christian Lee ("we," "us," "the Operator"). By creating an account or using the App, you agree to these Terms and to our Privacy Policy.

1. What the App is — and is not

MogTier is a self-improvement app. It includes:

  • A daily habit tracker with short guides, including morning and evening skincare routines.
  • A workout library with exercise pictures and timers.
  • A hairstyle library that rates each cut as an Excellent, Good or Bad fit for your face shape and hair type, with styling and barber instructions.
  • A hairstyle try-on (see below).
  • A Progress page showing how often you did each habit and your monthly rescan.
  • A facial analysis.

The facial analysis uses computer vision and a machine learning model to produce:

  • An AI-estimated attractiveness score.
  • Category-level analysis (Eye Area, Facial Proportions, Facial Harmony, Bone Structure, Skin Quality, Masculinity/Femininity).
  • A "Potential Score" modeling possible improvement from changes to modifiable characteristics only: skin condition, and facial fullness from body-fat loss. Never from changes to fixed bone structure, and never from grooming, hairstyle, or photo lighting — those are not part of how this score is calculated.
  • Recommendations for skincare, grooming, and facial de-bloating (hydration, sodium, and lifestyle guidance).
  • An AI-generated visualization illustrating one possible appearance with hairstyle and skin changed and facial puffiness slightly reduced. This is produced as part of every scan, which requires sending your front-facing photo to Replicate, a third-party AI provider (see the Privacy Policy, Section 8).

Hairstyle try-on. From any hairstyle in the library you can take one front-facing photo and receive an AI-generated picture of yourself with that haircut and clearer skin. It is available to MogTier Pro subscribers. It is separate from the facial analysis: the try-on photo is not measured or scored. The result screen shows the scores of your most recent logged scan (your program's latest monthly rescan, or its first scan) next to the pictures, and says which scan they are from; a try-on never changes them. It sends your front-facing photo to Replicate in the same way as the visualization above, and it costs one token (see Section 12).

Pictures in the App are illustrations. The exercise and hairstyle pictures show a faceless mannequin figure and were made with AI image tools. They show the idea of a movement or a haircut; they are not photographs of real people and not exact instructions.

What MogTier is for. Everything in the App, from scores to workouts, grooming and skincare, is general health and lifestyle information, not medical advice. Nothing in the App changes your bone structure or any other genetic feature. Our goal is to help you improve your health and lifestyle.

The App is strictly educational and informational. It is:

  • Not a medical device or diagnostic tool. Nothing in the App diagnoses, treats, or evaluates any medical condition, including skin conditions. Recommendations about skincare ingredients or routines are general information, not a treatment plan, and are not a substitute for consulting a dermatologist or other qualified healthcare professional — especially for any persistent or concerning skin condition.
  • Not a promoter of cosmetic surgery or medical procedures. The App does not recommend, refer for, or endorse any surgical or medical cosmetic procedure.
  • Not an objective measure of beauty or personal worth. See Section 2.

2. AI limitations and the subjective nature of attractiveness

All scores produced by the App are comparisons against published reference ranges. They are not, and are not presented as:

  • An objective or universal measure of attractiveness.
  • A statement of fact about you.
  • A measure of your worth, value, or desirability as a person.

How a score is actually produced. The App detects facial landmarks in your photos and computes geometric measurements from them (proportions, angles, and distances). Each measurement is then compared against a reference range for that proportion, and the results are combined into a single number. The same photos always produce the same score: nothing about the App is random, and no result depends on who is looking at it.

How much each area counts toward your score differs by sex, and you should know how that's decided. Between versions 1.8.0 and 1.9.0 of these Terms, how much each area counted toward a FEMALE score was fitted by regression to 289 ratings of women's faces, given by one person — the only part of the App built that way. As of version 1.9.0, it no longer is:

  • How much each area counts toward a female score is now set the same way it has always been set for men: a documented judgment call informed by published research on what predicts facial attractiveness, plus how well each area's geometry agrees with an independent, separately-run scoring tool across roughly a hundred public figures' published measurements. It is not fitted to any one person's ratings.
  • One rater's ratings of women's faces are still used, but only afterward, as a reported check on a subset of that data, never as the thing the weightings are chosen to match. That check is weak (correlation of about +0.13 on the portion of the data it could be run against) — it is disclosed for what it is, not implied to be validation.
  • A handful of individual female reference ranges also changed, separately from the weighting change above — see "Where the reference ranges come from" below for what and why.
  • The male score is entirely unchanged: every male reference range, every measurement, and the whole of how a male score is produced.

We are telling you this because a number set by documented judgment informed by published research and an independent comparison is a different kind of claim from a number fitted to one person's taste, and you cannot judge the score without knowing which you have.

Where the reference ranges come from. They have three different sources, and the difference matters:

  • Ranges used for your score are drawn from published clinical and aesthetic literature where one exists. These describe an ideal, not an average.
  • A handful of ranges used for a female score, where no clinical literature could be found, are instead reconstructed from a separate, independent scoring tool: specifically, the range of values that tool scores highly across roughly eighty to a hundred public figures per measurement. This is a fixed table of numbers built once from that tool's output on public figures' published photos, not a database that stores or grows from any App user's own photo. It is still evidence about what an independent standard treats as ideal, not a measurement of what any group of people actually looks like, and it is disclosed separately because it is a different kind of source from the peer-reviewed literature above.
  • Ranges used for the Masculinity/Femininity card were measured by us, on a set of 575 photographs of people aged 20 to 29 spread roughly evenly across seven ethnic groups. These describe an average for a biological sex, not an ideal, and they are not counted in your score.

The ranges used for your score carry known bias, and you should know what it is. The published literature they come from was based on study groups predominantly of European descent, and several of the ranges come from small preference surveys rather than from measuring large populations. Research testing these classical proportion rules against real populations found they held for only a minority of people in every group studied, and held noticeably less often in non-European groups. The App applies one set of ranges to every user and never asks about your background. For many people this means the score measures distance from a standard that was not drawn around faces like theirs.

Facial measurements vary as much by ancestry as by sex. We measured this on our own data: for every measurement behind the Masculinity/Femininity card, the spread between ethnic groups was as large as the difference between the sexes, or larger. Because the App applies one average to everyone, a face can read as far from typical for reasons that have nothing to do with sex. We chose not to collect or ask about ethnicity, so the App cannot and does not correct for this.

We ask which biological sex applies before each scan, not once per account. Several reference ranges differ by sex, so the answer changes the numbers rather than only the labels. It applies to that scan alone and is not stored on your account.

Beauty is subjective and culturally variable. What the App measures is distance from a published standard, and that standard is narrower than the range of faces people actually find attractive. Treat every score as one narrow comparison, not a definitive judgment.

The score words are labels, not verdicts. Next to each score the App shows one word for the range it falls in: Bad (below 4), Medium (4 to 5.9), Good (6 to 7.9), Excellent (8 to 8.9) or Perfect (9 and above). The word is chosen by the score alone. It describes where that score sits on the App's own scale, not you as a person and not what anyone else would think of your face.

The "Potential Score" is a modeled estimate, not a guarantee. It represents what our scoring formula would output if certain modifiable factors (skin clarity and facial fullness) were improved to a reference level — it is not a prediction that you will achieve that specific score, and it is not a promise of any particular outcome from following the App's recommendations. Skin condition specifically cannot be read from a photo where hair or facial hair covers the patches the App samples, which is common for a beard or a fringe; once enough scans exist to compute one responsibly, the Potential Score substitutes a typical value (the median skin reading across other users) for that one factor rather than leaving it out, so the projection still reflects that skincare is a real lever even when this scan's own photo could not measure it. That substitute is never used for your actual score, and the App's API marks any figure built this way rather than blending it in silently.

The Skin Quality card can show that same substitute value too, once enough scans exist to compute one responsibly, rather than reporting "not measured" — so the card always shows a number when a photo problem with a known, common cause (hair or facial hair covering the patches we sample) prevents a real reading. That number is the median skin reading across other users, not a reading of your own skin, and the card says so. It is never counted toward your actual (non-Potential) score, which continues to leave unmeasured skin out and redistribute its weight exactly as before.

The Potential Score is also never shown less than 0.5 points above your actual score. This is a product decision, not a measurement: skin condition and grooming almost always have some real room to improve, even where our measurements find little, and a Potential Score that lands only hundredths of a point above your actual one would read as "you cannot become more attractive," which we do not believe and do not intend to imply. Your actual score never receives this adjustment — only the Potential Score, and only when the measured projection would otherwise fall short of it.

The AI-generated visualization is an illustrative simulation, not a prediction. It shows one possible, AI-generated depiction of modifiable changes (clearer skin and a different hairstyle — lighting, pose, and everything else in the photo are deliberately kept the same) — it is not a guarantee of what you would actually look like after making those changes, and it does not depict any change to your underlying facial structure.

The same is true of a hairstyle try-on picture. It is an AI drawing of the chosen haircut on your photo. Your own hair may not be able to do that cut, a barber or stylist may cut it differently, and the picture also clears your skin. It can also get details of your face or the haircut wrong. Treat it as a rough preview, not a promise of the result.

Hairstyle fit ratings are general guidance. "Excellent", "Good" and "Bad" come from fixed rules about how a cut's shape balances a face shape, and from whether the cut suits the hair type you told us you have. A cut your hair cannot do is rated Bad whatever your face shape. The face shape comes from your scan or from your own answer, and both can be wrong. The ratings are opinions built into the App, not a judgment about you.

3. No guarantee of results

We make no guarantee that following any recommendation provided by the App will change your score, your appearance, or how others perceive you. Individual results from skincare, grooming, or de-bloating changes vary significantly and depend on many factors outside the App's knowledge or control.

4. No medical advice

Nothing in the App constitutes medical advice. Skincare and grooming recommendations are general educational information about commonly available product categories and ingredients — they are not a diagnosis, a prescription, or a treatment plan, and we do not recommend or reference any prescription-only medication or treatment. If you have a persistent skin concern, an unexplained change in your skin, or any condition that worries you, consult a dermatologist or other qualified healthcare professional. Do not use the App as a substitute for professional medical care.

The same applies to the App's workouts, fat-loss guide and skincare routines: they are general information for healthy people. If you have an injury, a health condition or an eating disorder, or are pregnant, check with a doctor before starting a new exercise, diet or skincare routine, and stop any exercise that causes pain.

5. Your photos and your ownership rights

You own the photos you upload. We do not claim any ownership interest in your photos. By uploading a photo, you grant us a limited, non-exclusive license to process that photo solely to provide the analysis and features you requested (see the Privacy Policy for exactly how long photos are retained and how they're deleted). We do not use your photos for any other purpose, including model training, without your separate, explicit consent.

You confirm that:

  • You own or have the legal right to upload each photo you submit.
  • The photo is of yourself, or you have the explicit permission of the person depicted to upload it for analysis.
  • You will not upload a photo of a minor other than yourself (if you are yourself a minor using the App under Section 9) or of any person without their consent.

6. Acceptable use

You agree not to:

  • Upload photos of anyone other than yourself without their explicit consent.
  • Use the App to harass, bully, or make judgments about another person's appearance without their knowledge or consent.
  • Attempt to circumvent the App's image quality checks, rate limits, or authentication.
  • Use the App's outputs (including the AI visualization) to create misleading or deceptive content about yourself or others.
  • Use the App for any unlawful purpose or in violation of any applicable law.
  • Attempt to reverse-engineer, extract, or misuse the underlying machine learning models or their outputs at scale (e.g., automated scraping).

We reserve the right to suspend or terminate accounts that violate these Terms.

7. Copyright and takedown requests

We respect copyright and expect you to do the same. Section 5 already requires that you own or have the right to upload every photo you submit.

If you believe a photo submitted to the App infringes your copyright, send a notice to our designated agent at support@mogtier.app including all of the following (this is what 17 U.S.C. § 512(c)(3) requires, and an incomplete notice may not be actionable):

  1. A physical or electronic signature of the copyright owner, or of a person authorised to act on their behalf.
  2. Identification of the copyrighted work you claim has been infringed.
  3. Identification of the material you claim is infringing, with enough detail for us to locate it. Note that uploaded photos are permanently deleted within minutes of upload (see the Privacy Policy, Section 3), so in most cases the material will already be gone by the time a notice reaches us.
  4. Your contact details.
  5. A statement that you believe in good faith that the use is not authorised by the copyright owner, its agent, or the law.
  6. A statement, under penalty of perjury, that the information in the notice is accurate and that you are the owner or authorised to act on the owner's behalf.

Counter-notice. If your material was removed and you believe that was a mistake or a misidentification, you may send a counter-notice to the same address containing the elements set out in 17 U.S.C. § 512(g)(3).

Repeat infringers. We terminate, in appropriate circumstances, the accounts of users who repeatedly infringe copyright.

Designated agent. Copyright notices must go to Christian Lee, Humblegatan 28A, 172 39 Sundbyberg, Sweden, support@mogtier.app. This agent is registered with the U.S. Copyright Office's DMCA Designated Agent Directory (registered September 7, 2026), which is what makes this section's safe harbour operative rather than a claim that publishing this paragraph alone would not have been.

A note on what this section does and does not do. The App does not publish, share, or display your photos to anyone else, and deletes them within minutes, so the classic hosting scenario the DMCA was written for barely arises here. The more serious risk when somebody uploads a photo of another person is not copyright at all: it is that person's privacy and biometric rights, and their right of publicity. Those are addressed by Sections 5 and 6 and by the Privacy Policy, and are not waived or limited by this section.

8. Privacy summary

We collect the photos and account information described in the Privacy Policy, which explains in detail what we collect, how long we keep it (every uploaded photo is deleted within a short window of capture — see Section 3 of that policy), where it's stored, and how you can delete it. By using the App, you also agree to that policy.

9. Age requirements

You must be at least 13 years old to use the App — there is no way to use it below that age, including with a parent or guardian's help.

Users between 13 and 17 years old must have a parent or legal guardian give permission from that guardian's own email inbox before scanning is unlocked. The account holder enters a guardian's email address, which must be different from their own; we email that address a link; and the guardian gives or refuses permission on a web page that requires no app and no account. Nothing the account holder can do on their own device unlocks scanning.

The guardian is then sent a confirmation email containing a link that withdraws that permission at any time, without an app and without signing in. Withdrawal takes effect immediately, and also deletes the photographs, measurements and results the analysis produced. The account itself and any purchases on it are unaffected and can be dealt with separately.

This requires an answer from a mailbox the account holder does not control, but it does not verify anyone's identity or age. See the Privacy Policy's Section 7 for exactly what it does and does not establish.

Given that the App analyzes and comments on physical appearance — a topic that can affect body image, particularly for younger users — parents and guardians of users aged 13–17 are encouraged to review the App together with their teen. A guardian who has concerns can withdraw permission immediately using the link in their confirmation email, and the account holder can delete the account entirely from Settings.

The Creator Program (mogtier.app) is for adults only: you must be at least 18 years old to join it, connect an account to it, or be paid through it. You confirm this when you connect your first account, and we record when you did. If you are under 18, or we have good reason to believe you are, we may remove your Creator Program account and its data, and any earnings not yet paid are forfeited. The 13–17 guardian permission above applies only to the App, never to the Creator Program.

The Creator Program has its own agreement. If you take part in it, the Creator Program Agreement (mogtier.app/creator-agreement) governs the videos you submit, what you are paid, our rights in those videos, and the payment announcements we post on Discord. It applies in addition to these Terms and only to the Creator Program, never to the App.

10. Indemnification

This is the section that actually matters when a user uploads somebody else's photo, and it is the counterpart to the promises you make in Sections 5 and 6.

To the fullest extent permitted by applicable law, you agree to indemnify, defend, and hold harmless Christian Lee and its officers, employees, and affiliates from any claim, demand, loss, liability, or expense (including reasonable legal fees) brought by a third party and arising out of:

  • a photo you uploaded that you did not own or have the right to upload;
  • a photo you uploaded of another person without that person's consent, including any claim under a biometric privacy, data protection, publicity, or image-rights law;
  • your use of the App in breach of Section 6 (Acceptable use) or of any applicable law; or
  • your use of the App's outputs, including any AI-generated image.

We will tell you about any such claim and you may take over its defence, provided you do not settle it in a way that admits fault on our behalf or imposes any obligation on us without our written agreement.

This does not limit any rights the person in the photo has against us. Indemnification is a promise between you and us; a third party whose face was uploaded without their consent can still bring a claim directly, and this section does not affect that. It determines who ultimately bears the cost, not whether the claim can be made.

11. Limitation of liability

To the fullest extent permitted by applicable law, Christian Lee and its officers, employees, and affiliates are not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the App, including but not limited to any emotional distress, dissatisfaction with a score or recommendation, or decisions you make based on the App's output. The App is provided "as is" and "as available," without warranties of any kind, express or implied, including warranties of accuracy, merchantability, or fitness for a particular purpose.

12. Subscriptions, tokens and payments

The App is free to download. Creating an account and taking the photos for a scan are free. Seeing a scan's result needs a token, and the rest of the App opens once you have made a first purchase (Section 12.1). Everything in this section applies only if you choose to buy something.

12.1 What is sold

  • MogTier Pro, an auto-renewing subscription, offered monthly or yearly. While it is active it includes:
    • one free token each week;
    • the 90-day improvement program, with its personalised daily tasks, streak, achievements and monthly rescan;
    • the guide behind each daily habit, and reminders;
    • the full workout library, including strength training and training plans, with timers;
    • the full hairstyle library, the fit rating of each cut for your face shape and hair, and the style finder;
    • the hairstyle try-on (each try-on also costs one token);
    • the Progress page.
  • Token bundles, one-off purchases of 3, 5 or 10 tokens. One token pays for either:
    • one full analysis, including its AI visualization; or
    • one hairstyle try-on, which is one picture made from one photo. The try-on is a MogTier Pro feature, so it needs an active subscription as well as the token. There is no retry: another picture, of the same or a different haircut, is a new try-on and costs another token.

What a token purchase opens without MogTier Pro. After your first purchase the App opens its main pages. Without an active subscription you can tick your daily habits, open a small sample of the workout library (currently one face and neck exercise and one cardio exercise) and of the hairstyle library (currently three hairstyles in each of the men's and women's libraries), and scan with tokens. Everything listed under MogTier Pro above is shown as locked. Which items are in the sample may change.

Monthly rescan. Inside the 90-day program, a scan can be logged as your monthly rescan only once in each 30-day period, during the rescan window at the end of that period. You can still run an ordinary scan at any time; only logging it as the program's monthly measurement is limited.

Exact prices are shown in the App before you buy, in your local currency, as set by the App Store or Google Play. The price you see on the purchase screen is the price you pay.

12.2 How you are charged

All purchases are made through Apple's App Store or Google Play, never directly by us. Payment is charged to your Apple or Google account at confirmation of purchase, and those companies — not we — hold your payment details. We never see your card number.

12.3 Auto-renewal, and how to stop it

A MogTier Pro subscription renews automatically. Your Apple or Google account is charged for another period, at the then-current price, unless you cancel at least 24 hours before the end of the current period. Renewal is the default; taking no action means you are charged again.

You cancel a subscription in your own store account settings — on iOS, Settings › your name › Subscriptions; on Android, Google Play › Subscriptions. We cannot cancel a subscription for you, and neither can deleting your MogTier account. Deleting the App does not cancel anything either. "Manage subscription" in the App's Settings opens the store's own subscription screen, which is normally the only place a cancellation can happen.

The one exception is losing access to the store account itself. If you can no longer sign in to the Apple or Google account your subscription is on, go to mogtier.app/cancel-subscription and submit a request there instead. In that specific case — and only that case — we can act on your behalf to have the subscription cancelled. This is not a general alternative to cancelling it yourself: if you still have access to your store account, use it directly, since that is faster and does not require us to verify your request first.

When you cancel, you keep everything the subscription includes until the end of the period you have already paid for. Nothing is cut off early.

12.4 Tokens are consumable and are not restored

Tokens are consumables. Once a token is spent on an analysis or a hairstyle try-on it is gone, and unlike a subscription it cannot be restored — this is how the app stores treat consumable purchases, and it is not a limitation we can waive. A try-on token is spent as soon as its picture is made, whether or not you like the result. The one case in which it is returned to your balance is when no picture could be made at all, for example because no face was found in the photo or the AI provider failed. Unspent tokens do not expire and are tied to your account rather than to a device, so they survive reinstalling the App or signing in on another phone.

Tokens have no cash value, cannot be transferred between accounts, and cannot be exchanged for money. Deleting your account forfeits any unspent tokens, because deletion removes the account they belong to.

12.5 Restoring purchases

If you reinstall the App or sign in on a new device, use Restore Purchases in the App. Because subscriptions and token balances are held against your MogTier account rather than your device, signing in normally restores them on its own.

12.6 Refunds

Refunds are handled by Apple and Google, not by us. We cannot issue, approve or refuse a refund for a purchase made through their stores. Request one through Apple (reportaproblem.apple.com) or Google Play, under whatever refund policy applies to you. You may also have refund or cancellation rights under the consumer law of your own country, and nothing in these Terms limits those.

If a store refunds a purchase, whatever it paid for may be withdrawn from your account, including a subscription or tokens that have not been spent.

12.7 Price and content changes

We may change prices. A change never affects a period you have already paid for, and where the stores require your consent to a subscription price increase, the subscription will not renew at the new price until you give it.

We may add, change or remove subscriber features. If we remove something substantial from an active subscription, you may cancel as described above and keep access until the end of the period you have paid for.

12.8 If you are a consumer in the EU or EEA

You normally have 14 days to withdraw from a distance contract without giving a reason. For digital content and digital services supplied immediately, that right is lost only if supply begins with your prior express consent and your acknowledgement that you thereby lose the right of withdrawal. Purchases are completed in the App Store or Google Play, so whether you gave that consent depends on their checkout. If you did not, you can withdraw within 14 days by asking Apple or Google for a refund, as described in Section 12.6.

Nothing in this section limits your statutory rights, including your rights if what you receive is faulty or not as described.

Complaints. If we reject a complaint you can refer it to Allmänna reklamationsnämnden (ARN), Box 174, 101 23 Stockholm, arn.se, whose decisions we will take part in. If you live in another EEA country you may use your own national alternative dispute resolution body instead.

13. Changes to these Terms

We may update these Terms from time to time. Material changes will be reflected in a new version number here and in docs/legal/CHANGELOG.md, and your continued use of the App after a material change constitutes acceptance of the updated Terms.

14. Governing law, disputes, and the rest of the agreement

Governing law. These Terms are governed by the laws of Sweden. If you are a consumer, this does not deprive you of the protection of the mandatory consumer-protection rules of the country you live in, and you may always bring proceedings in the courts of that country.

Severability. If any provision of these Terms is held to be invalid or unenforceable, that provision is severed and the rest remains in force. A provision that is too broad to be enforced applies to the maximum extent that is enforceable.

Entire agreement. These Terms and the Privacy Policy are the whole agreement between you and us about the App, and replace anything said or written before them about the same subject. The Creator Program Agreement is a separate agreement that covers only the Creator Program.

Assignment. You may not transfer your rights under these Terms. We may transfer ours to a successor of the business, and will tell you if that happens; your rights under these Terms are unaffected.

No waiver. If we do not enforce a provision, that is not a waiver of it.
