Terms of Use

At a glance

• 18+. Mainfit is for adults only.
• Subscription through Apple only. Mainfit Pro renews automatically until you cancel in Settings at least 24 hours before the period ends.
• Fair allowances. Each month, Pro includes up to 100 product photos, 30 outfit checks, 10 glow-ups, and 300 messages to the AI stylist.
• AI can be wrong. Product photos, color season, and style tips are suggestions without warranty. Your original photo is always kept.
• Your photos are yours. We only use them to provide Mainfit to you.
• Leave anytime. Delete your account and data right in the app.

Scope and provider

These terms apply to the Mainfit iPhone app and the features of Mainfit Pro. The provider and your contracting party for using the app is HK MEDIA GmbH, Kirchenstraße 10, 25335 Elmshorn, Germany (details in the legal notice), “we” below.

By tapping “Let’s go” on the welcome screen or when creating an account, you accept these terms; both places link to them. Conflicting terms do not apply. How we handle data is described in the privacy policy.

License to use the app

We grant you a non-exclusive, non-transferable, non-sublicensable right to use the app for personal purposes on Apple-branded devices that you own or control, as permitted by the Usage Rules of the Apple Media Services Terms (including Family Sharing where Apple allows it).

The app, its content (texts, design, example images, color palettes, software), and the “mainfit” brand are protected. All rights not expressly granted here remain with us.

Minimum age 18

You may only use Mainfit if you are at least 18 years old. Our AI providers only permit their services in offerings for adults. If you indicate during onboarding that you are younger, the app blocks use. Giving a false age violates these terms.

Guest and account

You can start using Mainfit without an account. Your items are then only available on this iPhone. With an account (Apple, Google, or email), your closet is available on any iPhone; your existing data moves into the account.

Keep your sign-in details secret and let us know if someone unauthorized might have access. You can delete your account anytime in the app (Profile → Delete account).

What Mainfit does

• Digital closet: photograph items or import them from Photos, edit, sort, and save outfits; also without AI.
• AI product photos: your photo becomes a product photo on a white background. The original is kept; you can compare and regenerate.
• Outfits for every day: suggestions based on weather, occasion, style, and color season, calculated on your iPhone, not by an AI.
• Color analysis: determines a color season on your iPhone, as guidance.
• Outfit check, glow-up, and AI stylist (Mainfit Pro): rating of an outfit photo, an improvement plan with an optional preview image, and a chat for style questions.
• Notifications and widget with your outfit of the day.

Example content (example closet, style and vibe tiles) is AI-generated and doesn’t show real users. Items and outfits from the example closet are labeled “Example”. The exact feature set is that of the current version of the app.

Mainfit Pro subscription terms

After onboarding, a subscription (“Mainfit Pro”) is required to keep using the app. There is a yearly plan and a monthly plan.

1. Purchase through Apple. You subscribe as an in-app purchase with your Apple Account. Billing is handled by Apple. Payment, invoicing, and refunds are governed by the Apple Media Services Terms. Confirm the purchase relationship (Apple as commissionaire) and how the right of withdrawal is presented.
2. Prices. The prices the app shows from the App Store before purchase apply, including applicable sales tax/VAT.
3. Free trial. The yearly plan may include a free trial if Apple confirms that you are eligible. The app shows its length before purchase. Unless you cancel at least 24 hours before it ends, it converts into the paid yearly subscription. If notifications are allowed, we remind you two days before it ends.
4. Automatic renewal. The subscription renews for the chosen period (one year or one month) until you cancel at least 24 hours before the period ends.
5. Cancellation. Cancel in Settings under your Apple Account → Subscriptions, or in the app under Profile → Manage subscription. Cancellation takes effect at the end of the current period; Pro stays active until then.
6. Price changes are implemented by Apple under its rules. For increases, Apple informs you in advance and asks for your consent where required.
7. Grace period. If a renewal payment fails, Apple may grant a grace period. Pro stays active during it.
8. Refunds are requested from Apple (reportaproblem.apple.com). If Apple refunds a purchase, Pro ends for that purchase.
9. After the subscription ends your items stay stored; the app then shows the subscription screen. Data export, account deletion, and your consents remain available from the account menu.
10. Deleting your account does not cancel the subscription. Cancel with Apple as well, otherwise it keeps renewing.
11. Restore. “Restore Purchases” links an existing subscription of your Apple Account to the Mainfit account you are signed in with. A subscription only applies to one Mainfit account at a time. When it moves to another account, this month’s allowance usage moves with it; this works at most once in 24 hours and three times in 30 days, beyond that [email protected] can help.

Monthly allowances

AI features cost us real money. Mainfit Pro therefore includes these allowances per calendar month (UTC):

• Unused allowances expire at the end of the month and don’t carry over. A new month starts on the 1st at 00:00 UTC.
• Without an active subscription you can try 3 free product photos in total, once per iPhone, even across reinstalls and account changes. Without a subscription you can add up to 30 items without a product photo.
• If the AI rejects a photo or a generation finally fails, it doesn’t count. A product photo that the accuracy check marks as “uncertain” counts, because it was created.
• You can see your usage in the app under Profile → Subscription & Limits.
• If our AI provider has an outage, or to protect against overload, AI features may pause temporarily. Your allowances are not affected.

AI results without warranty

Mainfit uses artificial intelligence. AI results are suggestions and may be wrong, incomplete, or unsuitable. We don’t warrant that they are correct or fit your purpose.

• AI product photos are generated depictions of your clothing. Colors, details, logos, or proportions may differ. That’s why the original is always kept, and you can regenerate or use the original.
• Color analysis is guidance, not professional color or style consulting. Lighting, camera, and makeup affect the result; you can adjust it.
• Outfit suggestions, outfit check, glow-up, and the AI stylist are recommendations. You decide whether an outfit suits the weather, occasion, or dress code. The AI stylist is an AI, not a human, and can make mistakes.
• Weather data comes from Apple Weather and may be inaccurate.
• Labeling: AI-generated images are labeled (in the image metadata and as “AI product photo” or “AI preview”). Don’t remove these labels and don’t present a glow-up preview as a real photo.

Your content

Photos and information you upload to Mainfit remain yours. For as long as you use Mainfit, you grant us a non-exclusive, free right to store them, process them technically (e.g., crop, product photo, cutout), show them to you, and – with your consent – send them to our AI provider for this purpose. We don’t use your content for advertising or to train AI models.

You confirm that you hold the necessary rights to your photos and that they

• only show other people with their permission (the app pixelates faces before uploading, but not reliably in every case),
• don’t show minors,
• contain no nudity, sexualized, violence-glorifying, or otherwise unlawful content,
• don’t violate the usage policies of our AI provider (Google’s Generative AI Prohibited Use Policy).

If content violates these rules, we may remove it and restrict features for your account.

Prohibited use

In particular, you may not:

• circumvent allowances, the free product photos, the age check, or other safeguards, e.g., through manipulated devices, multiple accounts, or automation;
• access the app or our interfaces automatically, in bulk, or for purposes other than personal use;
• decompile or replicate the app, unless the law expressly permits it;
• resell access or subscriptions or provide them to third parties for a fee;
• use Mainfit for unlawful purposes or to infringe the rights of others.

Availability and changes

We aim for reliable operation but can’t promise constant availability, for example during maintenance, outages at Apple or our AI provider, or force majeure. On-device features (closet, outfit of the day, color analysis) largely work offline as well.

We keep developing Mainfit and may change the app where reasonable for you, for example for new features, security, legal requirements, or changes to our providers’ offerings. If a change impairs your use of Mainfit Pro more than insignificantly, we’ll inform you in good time beforehand; you can then cancel the subscription with Apple. Your statutory rights regarding changes to digital products (Section 327r BGB) remain unaffected. Review the change clause under Section 327r BGB.

If we change these terms, we’ll inform you in the app beforehand. The new terms only apply to you once you accept them; if you don’t, either party may terminate the agreement. Define the acceptance flow in the app.

Warranty and liability

Statutory provisions for digital products apply to defects of the app (Sections 327 et seq. BGB).

We are liable without limitation for intent and gross negligence, for injury to life, body, or health, under the German Product Liability Act, and where we have given a guarantee. For slight negligence, we are only liable for breach of an essential contractual obligation – one whose fulfillment makes proper performance of the contract possible in the first place and on which you may regularly rely – and only for foreseeable damage typical for this type of contract. Otherwise, liability is excluded. These rules also apply to our employees and agents.

Apple-specific terms

Because you obtain the app through Apple’s App Store, the following also applies:

1. This agreement is concluded between you and us only, not with Apple. We alone are responsible for the app and its content.
2. Your license is limited to Apple-branded devices that you own or control, as permitted by the Usage Rules of the Apple Media Services Terms.
3. We alone provide maintenance and support ([email protected]). Apple has no obligation to do so.
4. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
5. We, not Apple, are responsible for addressing any claims relating to the app, such as product liability claims, claims that the app fails to conform to legal or regulatory requirements, and claims under consumer protection or privacy laws.
6. If a third party claims that the app or your use of it infringes their intellectual property rights, we – not Apple – are solely responsible for the investigation, defense, settlement, and discharge of that claim.
7. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
8. You must comply with applicable third-party terms when using the app, such as those of your wireless data provider.
9. Apple and its subsidiaries are third-party beneficiaries of this agreement. Upon your acceptance, Apple will have the right to enforce it against you as a third-party beneficiary.

Term, law, contact

The agreement runs for an indefinite period. You can end it anytime by deleting your account (cancel any subscription with Apple as well). We may terminate it with four weeks’ notice, or without notice for good cause – for example, serious violations of these terms. If we terminate without good cause, we refund subscription periods already paid on a pro rata basis. Clarify the refund path via Apple.

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, the mandatory consumer protection laws of the country where you habitually reside remain unaffected.

We do not take part in dispute resolution proceedings before a consumer arbitration board and are not obliged to.
