Terms of Use

§ 1 Who is entering into a contract with whom

PROOF is provided by Jeremy Meya, sole proprietorship, Walczer Straße 21, 59368 Werne, Germany (“we”). Full details are in the legal notice (German). The contract using PROOF is between you and us — not with Apple and not with Google. The two stores distribute the app and handle payments; what the app does is our responsibility.

Any differing terms of yours apply only if we have agreed to them in writing.

§ 2 What PROOF is

PROOF is an app in which a small group of friends — a Crew — agrees on a Challenge and each member submits one proof on every day it is due: a photo, or a video of up to five seconds, captured live in the app camera. If everyone delivers, a shared number grows, the Streak. If a single person misses the deadline, it goes back to zero for the whole Crew.

A Crew has three to eight members, or up to 32 as a Pro Crew. Joining is possible only through an invite code or link. There is no public area, no followers and no way to search for strangers.

PROOF is not a health, fitness or medical product. What you set out to do is your decision; the app only keeps count. It gives no training, nutrition or health advice and is no substitute for medical advice.

The AI check is an optional setting on a Challenge: an image model judges whether a photo shows what the Challenge asks for. It is an aid, not a referee — it can be wrong, and if the service is unavailable the proof counts. We do not promise any particular accuracy.

§ 3 Your account

You need an account to use PROOF. You can sign in with Apple, with Google or with an email address. Your details must be accurate; you may not choose a username that infringes the rights of others or deliberately impersonates someone.

An account belongs to one person. Do not pass on your credentials — whoever has them submits proofs in your name. If you notice that someone else has access, tell us: support@proofstreak.app.

You can delete your account at any time in the app (Profile → Account → Delete account) or, if you no longer have the device, through the form at Delete account (German).

§ 4 Age

PROOF is rated 13+. Anyone younger may not use the app.

If you are between 13 and 16 and live in Germany, you need the consent of your parents or another legal guardian — both for this contract and for the processing of your data (Art. 8 GDPR in conjunction with § 22 (1) BDSG). In other EU member states the age limit may be lower; then that limit applies. Minors may only buy paid features with the consent of their legal guardians.

§ 5 Your content

Your proof photos and videos, your comments and your voice messages remain yours. We acquire no ownership in them.

So that the app can work, you grant us a non-exclusive right, unlimited in territory and limited to the duration of storage, to store your content, to process it technically (for example to extract a still frame from a video or to resize a file) and to display it to the members of your Crew. This right expressly goes no further:

• We show your content to no one outside your Crew.
• We do not use it for advertising, marketing or store screenshots.
• We do not pass it on to third parties and we do not sell it.
• We do not train AI models with it.

You confirm that you hold the necessary rights in what you upload — and that people who are identifiable in a proof agree to it.

A submitted proof can no longer be swapped out. That is not a technical limitation but the core of the product: a group can only rely on something that nobody edits after the fact. You can still delete your content by deleting your account; what disappears when is set out in the privacy policy.

§ 6 What is not allowed

A Crew is a private space, not a lawless one. The following is prohibited:

• Content that breaks the law — in particular depictions of child sexual abuse, depictions of violence, incitement to hatred, insults, threats.
• Sexual or suggestive content, nudity, and anything that humiliates someone.
• Proofs in which people are identifiable without their consent.
• Passing off someone else’s content as your own proof, or circumventing the camera requirement by technical means.
• Harassing, excluding or pressuring others — including through nudges, reactions or comments.
• Automated access, scraping, rebuilding the interface, circumventing limits or payment functions.
• Multiple accounts in order to collect rewards, Coins or allowances more than once.
• Advertising, chain messages and anything bordering on spam.

Do not overdo it technically either: please access the services only to the extent that the app does.

§ 7 Reporting and moderation

Every proof and every comment by someone else can be reported in the app. Reported content is hidden from the reporting person immediately; from everyone else only once a decision has been made. Within a Crew that decision is made by the person who founded it — for a disagreement among friends that is the fastest route.

We reserve the right to hide or remove content and to suspend accounts temporarily or permanently where there is reasonable suspicion of a breach of § 6. For minor breaches we give notice beforehand where that is possible and reasonable. Your statutory rights are unaffected; you can contest a decision informally at support@proofstreak.app.

Where a child’s safety is concerned, the route bypasses the Crew. Anyone who suspects that a child is at risk reports it to us directly — no account needed. The address and the full procedure are at child safety (German).

§ 8 Paid features

PROOF is usable free of charge: one Crew, seven days of history, the complete daily loop. Beyond that there are three purchases, all inside the app:

PROOF Plus

€4.99 per month or €29.99 per year, with one week free for new subscribers. Auto-renewing subscription. Includes unlimited Crews, unlimited history, statistics, share cards without a watermark and three Freezes per month.

Pro Crew

€9.99 one-off. Applies to a Crew rather than to a person: up to 32 members, up to eight Challenges, and unlimited history, statistics and share cards without a watermark for every member. Not a subscription.

Single Freeze

€0.99 one-off. Saves one missed day. Not a subscription.

All prices are final prices and include statutory VAT. What counts is the price shown to you in the store before the purchase.

You pay through the store you got the app from — the App Store or Google Play. The store handles the payment and, depending on your country, is also your contracting party for the payment itself; it also issues the receipt. We never see your payment details.

A subscription renews automatically for the term booked unless you cancel at least 24 hours before it ends. Cancel where you bought it: on iPhone through your Apple ID (Settings → your name → Subscriptions), on Android through Google Play (profile picture → Payments and subscriptions). We cannot cancel a subscription for you — it does not run through us at all.

A free trial ends automatically with the first billing period. If you cancel, you keep the benefits until the end of the period you paid for. There is no pro-rata refund for an unused remainder unless the law requires one.

A Pro Crew belongs to the Crew, not to the person who paid for it. Whoever leaves the Crew does not take it along; whoever joins later gets it without paying. If the Crew is dissolved, the purchase is spent.

§ 9 Right of withdrawal

As a consumer you have a 14-day right of withdrawal for contracts covering digital content. It expires once we begin performance at your express request before the period ends and you have confirmed that you thereby lose your right of withdrawal (§ 356 (5) of the German Civil Code). That is the normal case here: a Freeze takes effect immediately, and a subscription unlocks its benefits in the same second.

Refunds run through the store you bought from — Apple and Google have their own procedures, and only they can reverse a payment. Write to us anyway if something went wrong: support@proofstreak.app. We cannot refund, but we can confirm the case to the store.

§ 10 Coins

Coins are an in-app currency that cannot be bought. They are earned by using the app — the daily coin, the Proof of the Week, people you bring in. They are spent on frames, cards and nudges.

• Coins have no monetary value and are not a means of payment.
• They cannot be paid out, transferred or exchanged.
• They expire without compensation when the account is deleted.

Coins also buy nothing that interferes with the mechanic — there is no Freeze for Coins.

§ 11 Availability and changes to the service

We aim for a continuously reachable service but do not owe any particular availability. Maintenance, problems at the hosting provider, at the push services of Apple and Google or on your own network can mean that something arrives late or not at all.

A Streak is a number, not an asset. We do not owe you that a Streak stands, grows or is preserved — not even if a push notification fails to arrive, an evaluation runs late or a proof does not get through because of a fault. If you believe a Streak was broken wrongly, write to us; we will look into it and restore it if the fault was ours. There is no claim to that, and no claim for damages.

We keep developing PROOF and may change, add or discontinue features. We will only restrict paid features during a running subscription period where there is an objective reason and the change is reasonable for you; if it is not, you may terminate for cause.

§ 12 Term and termination

The free usage relationship runs for an indefinite period. You can end it at any time by deleting your account. We may terminate it with 30 days’ notice to the end of a month; periods you have already paid for are unaffected.

Both sides keep the right to terminate for cause. For us, cause exists in particular in the event of a serious or repeated breach of § 6.

When the account ends, so does access to Crews, proofs and Coins. What is deleted afterwards and what has to be kept for legal reasons is set out in the privacy policy.

§ 13 Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, for fraudulently concealed defects, within the scope of a guarantee we have given, and under the German Product Liability Act.

For slight negligence we are liable only for breach of a material contractual obligation — that is, an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely. In that case liability is limited to the foreseeable damage typical for this kind of contract. There is no further liability.

Users are themselves responsible for the content they upload. We do not adopt it as our own.

If you post content that infringes the rights of third parties, you indemnify us against the resulting claims to the extent that you are responsible for the infringement.

§ 14 Changes to these terms

We may change these terms where there is an objective reason — for instance a change in the law, a court decision or a change to the product. We will announce the change at least 30 days in advance in the app or by email. If you do not object before it takes effect, it is deemed accepted; we will point this out separately in the announcement. If you object, you may end the contract before that date. Changes to your detriment that affect the core of the service require your express consent.

§ 15 Final provisions

German law applies. If you are a consumer, this applies only to the extent that it does not deprive you of the protection of mandatory provisions of the state in which you have your habitual residence.

We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration body; the European Commission’s online dispute resolution platform is linked in the legal notice (German).

Should any provision be invalid, the rest remains valid. The statutory rule takes the place of the invalid provision.

Annex: what also applies if you got the app from the App Store

Apple requires custom terms of use to contain the following points. They apply only to installations from the App Store and, in case of doubt, take precedence over the provisions above.

1. Acknowledgement. These terms are concluded between you and us only, and not with Apple. We alone are responsible for PROOF and its content.
2. Scope of licence. You receive a non-transferable right to use PROOF on Apple devices that you own or control, subject to the Usage Rules of the Apple Media Services Terms and Conditions.
3. Maintenance and support. We alone are responsible for maintenance and support. Apple has no obligation in that respect.
4. Warranty. We alone are responsible for the warranty. If the app fails to conform to the applicable warranty, you may notify Apple; Apple may then refund the purchase price to you. Beyond that, to the maximum extent permitted by law, Apple has no warranty obligation.
5. Product claims. We, not Apple, are responsible for claims relating to the app — including product liability, failure to conform to legal requirements, and claims under consumer protection or data protection law.
6. Third-party intellectual property. If a third party claims that the app infringes its intellectual property rights, we alone are responsible for the investigation, defence and settlement.
7. Export compliance. You represent that you are not located in a country subject to a U.S. embargo or designated by the U.S. government as supporting terrorism, and that you are not on any U.S. list of prohibited or restricted parties.
8. Name and address. Address questions, complaints and claims to: Jeremy Meya, Walczer Straße 21, 59368 Werne, Germany, support@proofstreak.app.
9. Third-party terms. You must comply with applicable third-party terms when using PROOF.
10. Third-party beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these terms and are entitled to enforce them against you.
