RUDITOOL / PRIVACY
Privacy policy
Last updated: 20 October 2026
Who we are
RudiTool is a drum practice app for iOS, iPadOS and macOS operated by Murat Abdukarimov. Privacy questions: support@rudnowski.dev.
Practice without an account
Practice, microphone analysis and guest history work without registration. Guest results are stored on your device until you explicitly move them into an account.
Account and practice data
If you sign in with Google or Apple, we process your email address or Apple relay address, Firebase sign-in identifier, nickname and manually selected country. Saved sessions may include exercise identifiers, dates, duration, BPM, timing accuracy and offset, practice reports and pattern snapshots. This data enables authentication, history and cross-device sync. Location is not requested.
Microphone
Microphone audio is processed on your device to detect strokes and assess timing. We do not upload microphone recordings. You can revoke microphone permission in system settings.
Optional leaderboard
If you opt in, your nickname, selected country flag, rank and score are visible to others. Your email and detailed practice history are not public. You can opt out in Profile.
Service providers and security
Firebase Authentication, Google and Apple provide account sign-in. Account history is stored by the RudiTool API on a hosted server and sent over HTTPS/TLS. We do not receive your Google or Apple password. We do not sell personal data. Server access logs may include IP address, request time, path and response status for operation and security; do not put sensitive information in URLs.
Retention and deletion
Guest data remains on the device until you remove it. Account data is retained to provide the account and history until you delete it. Profile → Delete account removes the account, server history and local data associated with that account; guest data remains. Operational backup copies may remain until replaced or removed and are not used for active account access. Contact support for questions about backups or a data request.
Your choices
You can practice without signing in, decline microphone access, opt out of the leaderboard and request access, correction or deletion of your personal data by contacting support@rudnowski.dev. Requests to recover or delete account data may require identity verification.
Website and updates
The public promotional pages do not use advertising trackers or analytics scripts. Hosting services may process technical request logs. Sign-in pages operated by Google or Apple follow their own privacy policies. We may update this policy; the current version and date are shown here.
