DiaryCBT — Privacy Policy

Effective date: 22 July 2026
Contact: senuna.app@gmail.com

DiaryCBT is a private, offline journaling and cognitive behavioral therapy (CBT) tool. Your privacy is the core design principle of this app.

The short version

  • We do not collect any of your data. Nothing you write ever leaves your device.
  • The app has no internet access. It does not declare the INTERNET permission, so it is technically incapable of transmitting your data anywhere.
  • No analytics, no advertising, no tracking, no third-party SDKs.
  • Your data is encrypted on your device.

What data the app stores (only on your device)

The app stores the content you create — journal entries, CBT thought records, mood ratings and check-ins, and your app settings. This information is saved only in local storage on your device.

  • The database is encrypted at rest using SQLCipher (AES-256).
  • Sensitive text fields are additionally encrypted using keys held in the Android Keystore.
  • An optional PIN lock can be enabled to gate access to the app.

What we do NOT do

  • We do not collect, transmit, sell, or share any personal information.
  • We do not use cookies, analytics, crash reporting, or advertising networks.
  • We do not have servers; there is no account and no sign-in.

Permissions

This version of the app requests no runtime permissions. (Future versions that add photo or audio attachments would request camera/microphone access only at the moment you use those features; this policy will be updated accordingly.)

Data retention and deletion

Because all data is stored locally:

  • You can delete individual entries and records within the app.
  • Uninstalling the app permanently deletes all of its data from your device. There is no cloud copy and no way to recover it — this is intentional.

Children

DiaryCBT is not directed at children under 13 and does not knowingly collect data from anyone (it collects no data at all).

Health disclaimer

DiaryCBT is a self-help journaling tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment, and is not a substitute for care from a qualified professional. If you are in crisis, contact your local emergency services or a crisis hotline.

Changes to this policy

If this policy changes, the updated version will be published at the same URL and the effective date above will be updated.
