Hide encrypted messages inside sound.
Privacy Policy · Last updated 20 June 2026
Blank has no accounts and no login. We do not collect your name, email, contacts, location, messages, passwords, or the audio you choose. Messages are encrypted and hidden locally; the resulting file only ever leaves your device if you choose to share it.
Blank Pro is a one-time in-app purchase processed by Apple. We use RevenueCat to manage entitlements (to know whether Pro is unlocked). RevenueCat receives a randomly generated, anonymous app-user identifier and the purchase receipt — not your name or contact details. This is used solely to deliver the feature you bought and to support “Restore purchase.”
Blank does not knowingly collect any information from anyone, including children.
If this policy changes, the “Last updated” date above will change accordingly.
