Last updated: 26 June 2026 · App: SilentBOX: Calculator Vault (com.silentkey.silentbox)
Short version: SilentBOX does not collect, transmit, sell, or share any of your data. Everything you put in the vault stays encrypted on your device and never leaves it. We have no servers, no accounts, and no analytics.
None. SilentBOX has no account system and no sign-up. The photos, files, and content you add to your vault are stored locally on your device. We do not have access to them, and they are never uploaded to us or to any third party.
SilentBOX makes no network connections to collect data, contains no third-party analytics or crash-reporting SDKs, and displays no advertising. There is no tracking of any kind.
SilentBOX uses your device's biometric capability (fingerprint or face) only to unlock your vault, and this happens entirely on-device. The app explicitly blocks access to your camera, microphone, and general device storage. We ask for as little as possible by design.
Vault content is encrypted and held in the app's private, on-device storage. Because nothing is sent off the device, there is no transmission to secure and no copy held anywhere else.
Your data remains on your device for as long as you keep it in the vault. You can remove individual items at any time, and uninstalling SilentBOX permanently removes all of its data from your device.
SilentBOX is intended for users aged 18 and over and is not directed at children.
We do not share data with third parties, because we do not collect any.
If this policy changes, we will update the date above and post the revised version at this URL.
