Secret Box is a local password manager, account manager and encrypted photo vault built for privacy. Your passwords, account details, documents, notes and private photos are encrypted and stored on your own phone by default. The app does not upload your private content to an app server.

If you want to keep sensitive information under your own control, Secret Box helps you manage it in one secure place. You only need one master password to access your real private vault.

Key features:

【Local encrypted storage】
Accounts, passwords, documents, notes and photos are encrypted on your device. No app server stores your private content, reducing the risk of server-side data leaks.

【Account and password manager】
Save website logins, email accounts, bank cards, credit cards, IDs, memberships, crypto accounts, AI accounts, recovery codes and other important information in organized categories.

【Random secure passwords】
Generate strong random passwords to help reduce password reuse across different accounts.

【Encrypted photo vault】
Import photos from your phone gallery and store them in the encrypted vault. You can also decrypt and export photos back to the system gallery when needed.

【Encrypted camera and filters】
Take photos directly inside the app and save them encrypted. Built-in camera filters make private photo capture easier and safer.

【Auto lock】
The app can lock automatically when idle or when moved to the background, helping protect your data when your phone is left unattended.

【Compass disguise】
Secret Box can disguise itself as a compass. You can enter the real vault with a special gesture or a preset compass angle.

【Fake vault】
Create a fake space to show harmless content when you do not want to reveal your real private vault.

【Intruder photo alert】
After repeated wrong master password attempts, the app can record the time, location and intruder photo, then send an alert to your verified email.

【Auto destroy after wrong attempts】
For higher security needs, you can set the app to destroy local data after too many wrong password attempts.

【Master password recovery】
Set up recovery information in advance so you can recover access through a secure verification process if you forget your master password.

【Dropbox encrypted backup】
Use your own Dropbox account to store encrypted backup files. Upload happens only when you enable backup. Backup files remain encrypted for safer phone migration and recovery.

Secret Box is more than a password manager. It is a local private vault for your accounts, photos, documents and sensitive information.
