Terms of service.

01 · Agreement

About these terms

Kevin DONG (“we”, “us”) provides Weight Track Assistant, an Android application for personal wellness tracking (the “app”). These Terms of Service (“Terms”) govern your use of the app and its online features.

By downloading, installing or using the app, you agree to these Terms. If you do not agree, please do not use the app. Our Privacy Policy explains how data is handled and forms part of these Terms.

02 · The Service

What the app does

The app is a personal tracking and wellness tool: weight logging and trends, body composition and measurements, goals, a GLP-1 companion (dose log, titration timeline, symptom timeline, injection sites, supply reminders, doctor visit summary), a nutrition and calorie diary, water tracking, workouts, progress photos, and home-screen widgets.

The app is free and supported by advertising. Some features (such as food search) rely on online services we operate; we may modify, suspend or discontinue any online feature, and we aim to tell you before material changes take effect.

Pro purchases

Existing Pro / ad-free purchases continue to work in 4.2. Pro is a legacy one-time ad-free purchase, not a subscription. Purchases are processed by Google Play and are subject to Google Play's payment and refund policies. If you believe you were charged incorrectly, contact us before making another purchase.

03 · Health Disclaimer

Not medical advice

The app is not a medical device and does not provide medical advice. Its GLP-1 features are tracking and educational tools only: they display the information you enter and general, publicly available product information, and they do not diagnose, treat, cure or prevent any condition.

04 · Eligibility

Who may use the app

You must be at least 13 years old (or the higher minimum age required in your country) to use the app. The app is not directed at children, and you should not use it on behalf of anyone else without their consent.

05 · Your Data

Your entries, your responsibility

Your entries, photos and notes belong to you. They are stored on your device; we do not receive a copy. This means:

• You are responsible for the backups you choose to keep. The app offers export (JSON, PDF, CSV) and excludes your health database and photos from Android cloud backup and device transfer.
• Deleting the app removes its data from the device. We cannot recover data we never had.
• If you connect Health Connect, that integration also runs under your control and Google's Health Connect terms.

See our Privacy Policy for the full details of every data flow.

06 · Acceptable Use

Using the app fairly

You agree to use the app only for lawful, personal purposes, and not to:

• attempt to disrupt, overload or interfere with our online services, or circumvent their protections;
• reverse engineer or modify the app except where such restriction is prohibited by applicable law;
• redistribute or resell the app, or misrepresent it as your own product.

07 · Third Parties & Ads

Other services inside the app

The app relies on third-party services: Google (Firebase, AdMob, Play Integrity), Cloudflare (food-search infrastructure), the USDA FoodData Central database, and, optionally, Health Connect. Those services are governed by their own terms and policies, and we are not responsible for their availability or actions.

The app displays advertising served by Google AdMob. Whether ads are personalised depends on your consent choice; see the Privacy Policy for details.

08 · Intellectual Property

Ownership

The app itself (code, design, brand, iconography) is owned by Kevin DONG and protected by copyright and other laws. You receive a personal, non-exclusive, non-transferable licence to use the app on your devices, solely as intended.

Your content is yours. Your entries, photos, diary content and notes remain your property. Because they stay on your device, we do not license or otherwise take rights in them.

09 · Disclaimers

The app is provided as is

The app and its online features are provided “as is” and “as available”, without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose and non-infringement, to the maximum extent permitted by law.

We do not warrant that the app will be uninterrupted or error-free, that online features will always be available, or that estimates and visualisations (trend lines, forecasts, TDEE and similar) are accurate. They are approximations for personal reference.

10 · Liability

Limitation of liability

To the maximum extent permitted by law, Kevin DONG will not be liable for indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits or health outcomes arising from your use of, or inability to use, the app.

Because the app is provided free of charge, our total aggregate liability for all claims is limited to the amount you paid us for the app (which is zero for the free version). Nothing in these Terms limits liability that cannot be limited by law. You remain responsible for your medical and health decisions; the app is a companion, not a caregiver.

11 · Changes

Changes to the app and these Terms

We may update the app and these Terms over time. The version number above changes whenever we do. If a change is material, we will highlight it in the app or on this page before it takes effect; continuing to use the app after that means you accept the updated Terms.

If any provision of these Terms is found unenforceable, the remaining provisions stay in force.
