Privacy Policy

Last Updated: July 2026

Gymerium is an Android workout tracker. Core workout data is stored locally on your device by default. This policy explains how data is handled when you use optional accounts, synchronization and backup features.

Information We Collect

When you use Gymerium, we may collect:

Account Information

Workout Data

Local Storage and Device Information

Workout information is stored locally on your device by default. Clearing app storage, uninstalling the app, or losing or damaging a device may remove unsynchronized local data.

Device, Analytics, and Crash Information

Gymerium uses Firebase Analytics to record app usage events, such as app opens and workout-related actions, and Firebase Crashlytics to receive crash and diagnostic information. These services may process limited device, app-version, and usage information needed to understand performance and reliability.

Google Sign-In and Google Drive Backup

If you choose to sign in with Google, Google provides the identity information needed to authenticate your Gymerium account. If you choose to link Google Drive Backup, Gymerium stores the Google access token on your device and uses the drive.file scope to create, read, and update Gymerium backup files in your Google Drive. We do not use Google Drive access for advertising.

Google Play Billing

If you purchase Gymerium Premium, payments are processed by Google Play. Gymerium sends the Google Play purchase token to our server only to verify the subscription and associate it with your Gymerium account. We do not receive or store your payment-card details.

How We Use Your Information

We use information to:

Data Storage and Sync

Creating or signing in to an account enables optional cloud synchronization. Supabase is used where applicable for authentication, storage and synchronization. Premium subscription records are stored only as needed to verify access. Multi-device sync is optional; core use does not require an account, and workout data remains on your device for the offline-first experience.

Data Sharing

We do not sell your personal information.

Information may be processed by service providers needed to operate optional account synchronization, storage and authentication, including Supabase; Google for Sign-In, Drive when you link it, and Play Billing; and Firebase for analytics and crash reporting. We do not sell personal information or use it for advertising.

Google API Limited Use Disclosure Gymerium's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Account Deletion

Users may delete their account and associated cloud data in the app under Settings → Data & Privacy → Delete Account, then type DELETE to confirm permanent deletion. Instructions for in-app deletion and requests without app access are available on the account-deletion page.

Account deletion removes the account, cloud workout data, feedback records, and Premium subscription association from our systems. Local workout data for that account is also removed from the device. Separately created offline-only data is not uploaded and remains on the device until you clear it from the app.

Backup copies and transaction records may be retained for a limited period where required by the provider, security needs or applicable law.

Data Security

We take reasonable measures to protect user information. However, no method of electronic storage or transmission is completely secure.

Children's Privacy

Gymerium is not intended for children under the age required by applicable law in their jurisdiction.

Changes to This Policy

We may update this Privacy Policy from time to time. Updates will be posted on this page with a revised effective date.
