DB Diary — Privacy Policy

Daily Diary for Police Officers

Last updated: 29 August 2026 · Applies to the Android app com.dbdiary.app

Short version: DB Diary does not collect, transmit or store your data on any server. Everything you write — diary entries, cases, tasks, photos and GPS marks — is saved only in the app's private storage on your own phone. There is no account, no sign-up, no analytics and no advertising.

1. Who this policy is for

This policy explains how the DB Diary mobile application ("the app") handles information. The app is an offline personal duty-diary tool. It is not affiliated with, endorsed by, or an official product of any police force, government department or public authority.

2. Information we collect

We collect nothing. The developer receives no personal information from the app. There are no servers, no accounts and no telemetry. The app contains no analytics SDK, no advertising SDK and no crash-reporting service.

3. Information you create, and where it stays

The app stores the following on your device only, inside the app's private storage area that other apps cannot read:

None of this is uploaded anywhere. Uninstalling the app deletes all of it.

4. Permissions and why they are asked for

PermissionWhyRequired?
MicrophoneTo dictate a diary entry instead of typing it.Optional
LocationTo stamp a crime-scene or patrol entry with coordinates, only when you tap "Capture GPS".Optional
Camera & photosTo attach a photograph to an entry.Optional
Notifications & alarmsTo show your daily diary reminder and court-date reminders on time.Optional
BiometricTo unlock the app with your fingerprint instead of the PIN.Optional

Every permission is optional. If you decline one, the rest of the app continues to work.

5. Speech recognition — please read

The dictation feature uses your device's own speech recognition service (normally the one supplied by Google or your handset manufacturer). Depending on your phone's settings, that service may send the audio to its provider's servers in order to convert it to text. That processing is governed by your device provider's privacy policy, not this one. The developer of DB Diary never receives your audio or the resulting text.

If you prefer that no audio ever leaves your phone, do not use the microphone button — type your entries instead, or enable your device's offline speech recognition where your handset supports it.

6. Exports, backups and sharing

You can export a duty report as a PDF, and you can create a backup file of your whole diary. Both are produced on your device and are only shared if you choose to share them.

Backup files are encrypted with AES-256 using a passphrase that you choose. That passphrase is never stored anywhere and is never sent to us. If you lose it, the backup cannot be recovered by anyone, including the developer.

Once you share an exported file — by WhatsApp, email, cloud drive or any other means — it is governed by the privacy policy of whichever service you sent it through. Please take care: diary entries may contain sensitive case information.

7. Automatic cloud backup

The app opts out of Android's automatic cloud backup, so your diary is not copied to Google Drive without your knowledge. The only backups that exist are the encrypted ones you create yourself.

8. Data sharing

We do not share, sell, rent or disclose your information to anybody, because we never have it in the first place.

9. Children

The app is a professional tool intended for adult police personnel. It is not directed at children under 13 and we do not knowingly collect any information from them.

10. Security

The database is kept in Android's private per-app storage. You can additionally enable an app lock with a 4-digit PIN and, if your phone supports it, a fingerprint. The PIN is stored only as a salted SHA-256 hash inside the Android Keystore. Please note that no security measure is absolute: a rooted or compromised device may expose app data, and you remain responsible for handling official information in accordance with your department's rules.

11. Legal reference feature

The app includes an offline quick-reference index of commonly used BNS and BNSS section numbers. It is a convenience aid only, is not legal advice, and may be incomplete or out of date. Always verify against the bare Act before relying on it.

12. Your rights and control

Because your data never leaves your device, you have complete control of it. You can edit or delete any entry, case or task at any time, and uninstalling the app erases everything it holds. There is no account to close and nothing for us to delete on your behalf.

13. Changes to this policy

If this policy changes, the updated version will be published at this address with a new "last updated" date. Material changes will also be noted in the app's release notes.
