At Calculator Vault · Hide Photos, your privacy and data security are our top priorities. This Privacy Policy explains what data we collect, how we use it, and how we keep your information safe.
All your photos and videos are stored locally on your device only.
Calculator Vault · Hide Photos does not upload your files to external servers or cloud storage services.
The app may appear as a standard calculator interface to help provide additional privacy protection for your personal content.
Access to hidden content requires successful authentication using your PIN or biometric authentication.
We do not require any user account, email registration, or personal information to use the app.
We also do not track your usage or behavior within the app.
All files saved inside the app are encrypted using AES-256 encryption, an industry-standard encryption technology designed to protect your private content.
You can secure access to your vault using:
Main PIN code
Optional Decoy PIN
Face ID / Touch ID
Decoy PIN allows users to open a separate vault for additional privacy protection.
These credentials are stored securely using Apple's security technologies and are never sent to external servers.
Users may also activate Face ID / Touch ID authentication by swiping up on the calculator screen.
We request the following permissions for key app functionalities:
Camera: To let you take photos/videos directly into the app
Photo Library: To allow importing media from your device
Face ID / Touch ID: To unlock the app securely and conveniently
We only request permissions that are strictly necessary to protect your privacy and improve usability.
All data stays on your device.
When you delete a file, it is first moved to the Trash within the app and remains there for 30 days.
You can restore deleted items during this time.
After 30 days, items in Trash will be permanently deleted and cannot be recovered.
Because data is stored locally on your device only, uninstalling the app will permanently remove all stored content, including items in Trash.
Calculator Vault · Hide Photos does not use cloud storage, online accounts, or external servers.
Because of this, we cannot recover your encrypted data, Main PIN, or Decoy PIN if they are lost or forgotten.
Please remember your credentials carefully.
We do not share, sell, transmit, or provide access to your data to any third party.
Your data belongs to you — always.
Calculator Vault · Hide Photos is not intended for use by children under the age of 13.
We do not knowingly collect personal data from anyone.
We may update this Privacy Policy to reflect improvements, feature updates, or legal requirements.
You will be notified through the app if any significant changes are made.
