Privacy Policy
Last updated June 22, 2026
Just LFT (“the app”) is an iOS workout tracker developed by Cristóbal Gómara (“we”, “us”). This policy explains what data the app collects, why, and the choices you have.
We keep data collection to what the app needs to work. We do not sell your data and we do not use it for advertising or cross-app tracking.
Account information
An account is required to use the app. You sign in with Sign in with Apple, which gives us a unique identifier and the email (or Apple’s private relay address) and name you choose to share. We use this to create your account and sync your data across your devices.
Workout and fitness data
We store the content you create in the app: workout templates, logged sessions, sets, exercises, personal records, notes and related training data.
This data is stored locally on your device and synced to our backend so you can access it across devices and restore it if you reinstall. It is tied to your account and is not shared with other users.
Subscriptions and purchases
Optional Pro subscriptions are sold through the Apple App Store and managed with RevenueCat, our subscription provider. We receive your purchase and entitlement status (for example, whether you have an active subscription) so we can unlock Pro features.
Payments are processed by Apple. We never receive your card or full payment details.
Diagnostics and usage
To keep the app stable we use Sentry for crash reporting, which collects technical details about crashes (device model, OS version, and the error). To understand how features are used we use TelemetryDeck, a privacy-friendly analytics service that does not build advertising profiles or track you across other apps.
How we use your information
- Provide the app and sync your data across your devices.
- Manage your account and subscription entitlements.
- Diagnose crashes and fix bugs.
- Understand which features are used so we can improve the app.
Service providers
We share data only with the providers needed to run the app, acting on our behalf:
- Apple — authentication (Sign in with Apple) and payments.
- Supabase — database, authentication and backend hosting for your account and synced data.
- RevenueCat — subscription and purchase management.
- Sentry — crash reporting.
- TelemetryDeck — privacy-friendly product analytics.
Data storage and security
Your synced data is stored on our backend (Supabase) and protected by access controls so that only your account can read or write it. We take reasonable measures to protect your data, though no method of storage or transmission is completely secure.
Data retention and deletion
We keep your data while your account is active. You can delete your account from within the app at any time; this removes your account and associated data from our backend. You can also contact us at support@justlft.com to request deletion.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data. To exercise these rights, contact us at support@justlft.com.
Children
The app is not directed to children and is not intended for anyone under the age required to consent to data processing in their country. We do not knowingly collect data from children.
Changes to this policy
We may update this policy from time to time. We will update the date above when we do, and significant changes will be reflected here.
