Tactus has no analytics, no advertising, and no server of its own. On iOS, everything lives on your device and, if you choose, in your iCloud. On Android, you can optionally sign in with Google to back up to your own Drive. Nothing is ever required.
Everything you create, passages, bar structures, meters, accent maps, tempo shapes, is stored as files on your device. On iOS, if you have iCloud Drive enabled, those files sync to your personal iCloud account so they appear on all your devices. On Android, you can optionally sign in with Google to back up the same files to a folder Tactus creates in your own Google Drive.
Apple operates iCloud and Google operates Drive; each is subject to its own privacy policy (Apple's, Google's). Tactus itself has no visibility into your iCloud or Drive files: sync happens directly between your device and Apple or Google, never through a server Tactus operates. On Android, Tactus only ever requests access to the files and folders it creates itself (Google's drive.file scope), never your whole Drive.
When you share a passage from the share sheet, a .rhythmmap file is created in your device's temporary storage and passed to whichever app or service you choose, AirDrop, Mail, Messages, Files. Tactus does not transmit this file anywhere on its own. You choose where it goes.
Tactus has no account or server of its own, so there's nothing on our end to delete. Everything lives on your device and, if you signed in, your own Google Drive. To fully remove your data:
Once you've done this, no Tactus-related data remains anywhere. There's no developer-held copy to request deletion of, because none has ever existed.
The fastest way to describe what an app does with your data is to list what it never asks for. Here is the complete list for Tactus.
No Tactus account, ever. On Android, an optional Google Sign-In lets you back up to your own Drive. Skip it and the app behaves exactly like iOS.
No usage tracking of any kind. No first-party or third-party analytics SDKs.
No crash reports sent to any server we operate. iOS may offer to send crash data to Apple separately.
No ad SDKs, no targeting, no banners. Tactus is paid for once and never sees you again.
Tap Tempo uses touch timing only. No audio is recorded at any point.
No camera access is requested or used.
No location data, coarse or precise, is requested or used.
Sharing a passage uses the system share sheet. Your address book never touches the app.
App Store purchases are handled entirely by Apple. Tactus stores no payment information.
Tactus generates click sounds using your device's audio hardware: AVAudioEngine on iOS, the Oboe library on Android. It does not record audio on either platform. It does not access your microphone. All audio is synthesized locally and plays through your speaker or headphones.
Tactus is a one-time purchase sold through the Apple App Store (iOS) and Google Play (Android). Payment processing, purchase records, and receipt validation are handled entirely by Apple or Google, whichever store you bought it through. Tactus does not receive or store your payment information.
See Apple's Privacy Policy or Google's Privacy Policy for details on how each store handles transactions.
Tactus does not knowingly collect any personal information from anyone, including children under 13 (or the applicable age in your jurisdiction). The only personal data the app ever handles is a Google account email, and only if a user on Android chooses to sign in for backup (a feature aimed at people managing their own cloud storage, not children). Tactus does not knowingly direct this feature at children.

If the app adds features that change how data is handled, this policy will be updated and the effective date at the top will change. Significant changes will be noted in the App Store release notes.
The version above governs the current release of Tactus on the App Store and Google Play.
