VocaLock — Privacy Policy

Last updated 28 September 2026 · Indidino

VocaLock listens through your microphone so it can hear your claps and your spoken phrases. That is the whole reason the app exists, so we want to be exact about what happens to that audio.

Audio never leaves your phone

Every sound VocaLock hears is processed on the device, in memory, and thrown away immediately. Nothing is recorded to a file. Nothing is uploaded. No audio is sent to us, to any server, or to any third party. The speech model used to match your phrases is bundled inside the app and runs entirely offline.

What we store

Your plan status, your phrases and your settings are stored on your device. Your backup PIN is never stored — only a salted one-way hash of it, held in Android's encrypted storage. We cannot read your PIN, and neither can anyone who obtains the file.

If you sign in, your mobile number is used to keep your subscription attached to you. It is not sold, shared, or used for advertising.

Permissions, and why each is needed

• Microphone — to hear claps and spoken phrases.
• Notifications — to show the listening notice and its Stop button.
• Camera — only to switch the flashlight on and off. VocaLock never opens the camera or takes pictures.
• Battery exemption — so Android does not shut the listener down.
• Device admin (lock screen only) — if you choose "Use my phone's lock", VocaLock asks Android to lock your screen when it hears your phrase. It requests the force-lock policy and nothing else: it cannot wipe your device, change your password, or disable your camera.

Children

VocaLock is not directed at children under 13 and we do not knowingly collect their data.

Changes

If this policy changes, the date at the top of this page changes with it.
