Streakbound Terms of Use

Effective date: 19 August 2026　|　Last updated: 19 August 2026

Important: Please read these Terms before using Streakbound (the “App”). By tapping Agree, downloading, installing, or continuing from the sign-in screen, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. The service

The App is a general health and fitness tracking tool. It helps you record and manage a health and weight-loss journey through daily check-ins, cycle (challenge) management, before-and-after comparisons, Tools (intermittent fasting), and AI Coach. For the first 3 days after download, the App provides a trial based on the on-device first-launch time. That trial is managed by the App and is not an Apple App Store Introductory Offer. Trial rules and member features are as shown in the App.

Not a medical device: the App is for general health and fitness tracking. It is not a medical device and does not provide medical diagnosis, treatment, or professional medical advice. Consult a qualified clinician before starting any diet, nutrition, or exercise program.

2. Accounts, anonymous use, and on-device ownership

The App uses the following account model:

  1. Signed-out (anonymous) use: after download you may use the App with an anonymous device ID (UUID, stored in the on-device Keychain). Local data (check-ins, challenges, photos, and similar) is tied to that ID. The same identifier also anchors the 3-day trial window. Uninstalling the App usually does not remove that Keychain item.
  2. Sign-in: you may sign in from Settings with Sign in with Apple. On first authorization, Apple may provide your name and email so we can create an account and a default nickname. See the Streakbound Privacy Policy for details.
  3. On-device reassignment: when you sign in, we may reassign on-device data from the anonymous device ID to your user account. This only changes local ownership. It does not upload weight, photos, or check-in records to the cloud.
  4. Sign-in on a new device: we do not currently offer cloud backup or cross-device sync. If you sign in on a new device, that device will not automatically receive historical check-ins and photos from the previous device. Our servers store only account details and subscription status associated after sign-in.

You must keep your device and account credentials safe. You are responsible for problems with the account or data that result from failing to do so.

3. Acceptable use

When you use the App, you agree to:

  1. Comply with applicable law and the rules where you live;
  2. Upload and enter only true, lawful information about yourself, and not other people’s information or false or illegal content;
  3. Not use the App for anything unlawful, anything that infringes others’ rights, or anything that interferes with the App;
  4. Understand that all information, suggestions, and analysis in the App are for reference only and do not replace professional medical advice.

If you breach these Terms or applicable law, we may reasonably limit, suspend, or end your access to related features.

4. Intellectual property

The App and related software, documentation, interface, trademarks, logos, and the name “Streakbound” (the “App Content”) are protected by applicable intellectual-property law. We or our licensors retain all rights in the App Content.

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable personal license to use the App on supported devices and platforms for its intended purpose. You may not reverse-engineer, decompile, disassemble, copy, modify, distribute, or use the App for commercial purposes, except where applicable law expressly allows.

Content you enter or capture in the App (such as check-in photos and weight records) remains yours to the extent applicable law allows. You grant us a limited license to process that content only as needed to operate the App (for example generating comparison images or achievement posters on the device, and exporting images when you choose to share).

5. Subscriptions

The App offers auto-renewable subscriptions. In-app purchases go through the Apple App Store (StoreKit). Apple processes payment. We do not collect your card details.

5.1 Auto-renewable subscriptions (monthly / yearly)

  1. The subscription group is Streakbound Premium. Plans are monthly (1 month) and yearly (1 year). Feature access for each plan is as shown in the App;
  2. Auto-renewal: the subscription starts when your purchase is confirmed and renews at the end of each period until you cancel;
  3. Cancellation: manage or cancel in your Apple ID subscription settings. After you cancel, access usually continues until the end of the period you already paid for;
  4. Refunds: follow Apple’s refund rules and your Apple ID settings;
  5. Trial: the first 3 days after download are managed by the App using the on-device first-launch time. This is not an App Store Introductory Offer. If an App Store free trial is offered later, manage the subscription in Apple ID settings before the trial ends to avoid charges;
  6. Plan changes: upgrades and downgrades between monthly and yearly follow in-App display and Apple’s subscription rules.

5.2 Pricing and taxes

Prices and available plans are those shown in your App Store storefront in the App. Prices may vary by region, exchange rate, and applicable tax. We may change prices or add or adjust plans after prior notice (including in-App notice).

6. AI Coach

AI Coach is powered by a large language model provider. Requests are currently forwarded through our proxy to Alibaba Cloud DashScope (Qwen qwen-flash). The feature is off by default and requires confirmation in Settings. By using AI Coach you understand and agree that:

  1. The App will send a structured weight trend (current / starting / previous weight, days, unit, and interface language) to the third-party AI provider, not an open chat and not your name, photos, or account identifier;
  2. AI output is general information only. It is not medical, legal, financial, or other professional advice;
  3. You are responsible for any decision you make based on AI Coach content;
  4. You must not use AI Coach to generate or spread unlawful, infringing, false, harassing, or harmful content.

We do not warrant that AI Coach output is true, accurate, complete, or suitable for you, and we are not liable for consequences of relying on it. After you turn the feature off, the App will not send new requests to the third-party AI.

7. Disclaimers and limitation of liability

To the maximum extent permitted by applicable law:

  1. The App is provided “as is” and “as available.” We do not warrant that it will be continuously available, uninterrupted, error-free, or fully suited to your needs;
  2. We are not liable for any indirect, incidental, special, consequential, or punitive damages arising from use of or inability to use the App, or from relying on information in the App (including AI Coach output);
  3. Our aggregate liability, to the extent permitted by law, is limited to the amounts you actually paid us for the App in the previous 12 months (or the lowest amount the law allows if you paid nothing).

Nothing in this section affects rights that cannot be excluded or limited for you as a consumer.

8. Indemnity

You agree to indemnify and hold harmless us and our affiliates, directors, and employees from claims, losses, liabilities, and expenses (including reasonable attorneys’ fees) arising from your breach of these Terms, your breach of law, or your infringement of any third-party right.

9. Changes to these Terms

We may update these Terms from time to time. If a change is material, we will notify you in the App (notice or dialog). The updated Terms apply from the Effective date or Last updated date at the top. Continued use of the App after an update means you accept the updated Terms.

10. Termination

You may stop using the App at any time by uninstalling it. Signed-in users who want the server-side account deleted should email the address in Section 12. We will handle a verifiable request within 30 days. The scope of deletion and how it relates to on-device data is described in the Streakbound Privacy Policy. These Terms do not provide, and do not imply, an in-app “Delete Account” button. Uninstalling or deleting the server-side account does not cancel auto-renewal on Apple’s side. You must manage that in Apple ID subscription settings.

We may also limit, suspend, or terminate access if you seriously breach these Terms or applicable law. Provisions that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnity, and governing law) survive termination.

11. Governing law, disputes, and consumer rights

The formation, validity, interpretation, performance, and dispute resolution of these Terms are governed by the laws of the People’s Republic of China (excluding conflict-of-law rules), except where mandatory law provides otherwise.

If a dispute arises from these Terms or the App, the parties should first try to resolve it amicably. If that fails, either party may submit the dispute to a people’s court with jurisdiction in Chengdu, Sichuan Province, or pursue another dispute-resolution method required by law.

Nothing in this governing-law and dispute section affects mandatory consumer-protection rights you have in your place of residence.
