Lightweight Privacy Policy

Last updated: 5 July 2026

Lightweight ("Lightweight", "we", "us") is a gym-tracking app for logging workouts, collecting the gyms you train at, and sharing progress with friends. This policy explains what we collect, why, and the control you have over it. It applies to the Lightweight mobile app and its backend.

Information we collect

• Account — your email address (and, if you use Google or Apple sign-in, the identifier those providers return) so you can sign in and we can secure your account.
• Training data — the workouts, exercises, sets, routines, and personal records you create, plus the gyms and locations you choose to associate with a workout.
• Location — used only when you ask (to suggest nearby gyms or confirm a visit). The Android app uses foreground location only. On iOS, if you enable it, Lightweight may use a single active-workout geofence to remind you a workout is still running if you leave the gym. Location is not used for continuous tracking, advertising, or analytics.
• WHOOP health data (optional) — if you connect a WHOOP account, we retrieve your recovery score, heart-rate variability (HRV), resting heart rate, and daily strain, along with the WHOOP profile identifier needed to link the account. We only request read access, and only for the categories listed here.

How we use it

We use this information to operate the app: to log and display your training, power records and achievements, show gym discovery and passport features, and — where you have connected WHOOP — to display your recovery and strain alongside your training. We do not use your data for advertising and we do not sell it.

How WHOOP data is handled

Connecting WHOOP uses OAuth 2.0. The access and refresh tokens WHOOP issues are stored only on our backend (Supabase) and are never exposed to the app or to any third party. The health metrics we retrieve are stored against your account and shown only to you. You can revoke this at any time in Settings → Health → WHOOP → Disconnect, which asks WHOOP to revoke our access and deletes the stored tokens. You can also revoke access directly from your WHOOP account settings.

Where your data lives and who processes it

Lightweight is built on service providers who process data on our behalf: Supabase (authentication, database, and storage), WHOOP (only if you connect it, as the source of the health data above), and, for optional features, app-store billing via RevenueCat and maps via Mapbox. We share the minimum necessary with each and do not share your data with anyone else except where required by law.

Retention and deletion

We keep your data for as long as your account exists. Disconnecting WHOOP removes the stored WHOOP tokens. Deleting your account (Settings → Account → Delete account) permanently removes your account and associated data from our systems.

Your rights

You can access, correct, export, or delete your data from within the app, or by contacting us. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA; we honour those requests.

Children

Lightweight is not directed to children under 13 (or the minimum age in your country), and we do not knowingly collect their data.

Changes

We may update this policy; material changes will be reflected by the "last updated" date above and, where appropriate, communicated in the app.

Terms

Lightweight Terms of Use

These terms apply to your use of the Lightweight mobile app and related services. By using Lightweight, you agree to use it responsibly and in accordance with these terms.

Eligibility

Lightweight is intended for users who are at least 18 years old, or the age of majority where they live.

Training and health

Lightweight is a workout logging and social app. It is not medical advice, coaching, diagnosis, or a substitute for professional guidance. You are responsible for training safely and choosing exercises, loads, and routines appropriate for you.

Your content

You are responsible for workouts, profile details, comments, photos, and other content you add to Lightweight. Do not upload or share content that is unlawful, abusive, harassing, hateful, sexually explicit, exploitative, deceptive, infringing, or otherwise objectionable.

Moderation

Lightweight may remove content, restrict visibility, suspend access, or take other action when content or behavior violates these terms or harms other users. Users can report content and block other users in the app.

Subscriptions

If Lightweight offers paid features, purchases are handled by the relevant app store. Subscription renewal, cancellation, refunds, and billing are managed through your Apple App Store or Google Play account.

Account deletion

You can delete your account in the app from Settings > Account > Delete account. Deletion removes your account and associated personal data from our systems, subject to limited retention where required for security, legal, or abuse-prevention reasons.
