Install Checklist
- Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
- File size is a light 4.67 MB, so it installs quickly even on modest connections.
- This build is signed by "Aidin Gharibnavaz" — always verify the developer name matches what's listed on the app's official store page before installing an update.
- After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
- We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.
About this app
any of your private data to anyone.
Messages produced by this app are secure and, for example, can be
confidently sent over a network. It uses AES in GCM mode with no padding for
encryption. It uses Argon2 and a random Salt to derive a secure key from the
entered passphrase.
This is a very powerful encryption. It also encrypts its settings before storing
them on the device.
However, the app might be vulnerable to some attacks. Although it is secure
enough to stand attacks from non-expert crackers, e.g. normal users,
should not be used for serious data encryption.
Upgrading from 4.x to 5.x
The encryption of the settings is changed. The app should be able to detect the
old settings and upgrade them with the new encryption algorithm. However, it's
a good idea to back-up your passphrase. (Well, it's generally a good idea to
back-up encryption keys and passwords in a secure place).
If the app didn't work after upgrade, uninstall and install it again.
