Racketendar Privacy Policy
Last Updated: July 1, 2026
Racketendar ("the App") takes your privacy very seriously. This Privacy Policy explains how your data is collected, used, and protected when you use our application. Racketendar is an offline-first app where you have full control over your data.
1. Data Collection and Usage
Racketendar may request access to certain features on your device to provide its services:
- Camera and Photo Gallery: We request access to your device's camera and photo gallery so you can add match and rival photos. The photos you select are stored only on your device.
- Contacts: We may request access to your contacts so you can quickly add rivals from your address book. Your contact data is never transferred outside the app (to any remote server).
- Google Account (Optional):
- Google Calendar: If you wish to save your matches to your Google Calendar, you must grant the app permission to access your calendar and create new events (matches).
- Google Drive: If you wish to back up your data, Racketendar only accesses the specific backup files and folder it creates on your Google Drive. The app cannot access or read any other files or folders in your Google Drive.
2. Data Storage and Sharing
- No Remote Server (Backend): All match results, statistics, and rival information you enter into Racketendar are securely stored only in your device's local memory (SQLite database).
- No Sharing with Third Parties: Since we do not have a remote server, your personal data is never collected, sold, or shared with third-party advertising/marketing companies.
The app does not use any external analytics tools (Analytics) or crash tracking tools (Crashlytics) to analyze your usage statistics.
3. Data Protection Mechanisms for Sensitive Data
Racketendar is committed to protecting your sensitive data, including data accessed via Google Workspace APIs, using industry-standard security practices:
- Encryption in Transit: All communications between the Racketendar app and Google's servers (such as when backing up to Google Drive or syncing with Google Calendar) are encrypted in transit using secure HTTPS/TLS protocols.
- Encryption at Rest: All sensitive data stored locally on your device (within the SQLite database) is protected by the operating system's standard file encryption and security sandboxing mechanisms (iOS and Android). Data backed up to your Google Drive is protected by Google's encryption at rest.
- Restricted Access: We strictly limit access to your data. Racketendar operates entirely on your device and communicates directly with Google's APIs. We do not have our own backend servers, meaning our development team has absolutely no access to your personal data, matches, or Google account information.
- Least Privilege: We request only the narrowest possible permissions (scopes) from Google APIs required to provide the backup and calendar sync features, adhering to the principle of least privilege.
4. User Rights and Data Deletion
You have full control over your data.
- Disconnecting Google: You can disconnect your Google Account synchronization at any time with a single tap from the "Settings > Data Management" section within the app.
- Deleting All Data: You can permanently delete all your records from your device by using the "Settings > Data Management > Delete All Local Data" option within the app.
- Google Drive Backups: If you have backed up your data to Google Drive, you can manually delete the spreadsheet named Racketendar_data and the folder named Racketendar_Data_Photos by logging into your Drive account.
5. Changes to This Policy
We may update this Privacy Policy from time to time. In the event of any changes, the new policy will be published within the app or on the app's store page.
