DRUM FLOW
Privacy Policy
DrumFlow is an offline-first drum practice and metronome application. It does not require an account and does not include advertising, analytics, payments, social features, microphone recognition, or cloud synchronization.
Information we do not collect
DrumFlow does not intentionally collect your name, email address, phone number, account credentials, location, contacts, photos, calendar, microphone recordings, drum-performance data, advertising identifiers, analytics events, crash reports, or tracking events.
Exercise update requests
When you explicitly select Check for updates, the app connects to exercise.drumflow.cc to download a signed exercise manifest and selected content. The connection necessarily exposes normal network metadata, such as IP address, request time, TLS metadata, and user-agent information, to the hosting, CDN, and security infrastructure. DrumFlow does not use this metadata to create a user profile or for advertising.
Local storage
Downloaded exercise JSON, notation artifacts, and a small local installation index are stored in the app's private storage. Language, skin, practice settings, and metronome settings are also kept locally. This data remains on your device unless you or the operating system removes the app data. Bundled exercises and audio are read from the application package.
Sharing
DrumFlow does not sell or share personal information. Hosting, CDN, and network security providers may process normal request metadata to deliver and protect the user-initiated exercise update service.
Security
Exercise update manifests are verified with the bundled Ed25519 public key, and downloaded content is checked against signed SHA-256 values before installation. Content-update requests require HTTPS. No security measure can guarantee absolute security, so keep the app and operating system updated.
Children
DrumFlow is a general-purpose music-practice tool. It does not knowingly collect personal information from children.
Data deletion
DrumFlow has no user account, so there is no account deletion workflow. You can remove locally downloaded content by clearing the app data or uninstalling the app.
Changes to this policy
If our data practices change, this policy will be updated before the change is released. The effective date above will be updated when a new version is published.
