DiaryKu Privacy Policy
Last updated: November 12, 2026
This policy explains what information the DiaryKu app (published by Amer InfoTech) collects, how it is used, and your choices.
Information we collect
DiaryKu has no accounts and does not send your diary, family details or reminders to us. We do not run any servers for this app. Everything you enter is used on your phone only.
What stays on your phone
- People and family details, birthdays, anniversaries, events, reminders, daily notes, photos you attach, tags and settings are saved only on your phone.
- This data is kept in an encrypted database. The encryption key is held in your phone's secure key storage (Android Keystore).
- You can lock the app with a PIN, fingerprint or face unlock. Fingerprint and face checks are done by Android. The app never receives your fingerprint or face data.
Permissions
- Notifications and alarms - to remind you of birthdays, anniversaries and events at the time you choose. Reminders are scheduled on your phone.
- Photos and camera - only when you choose to attach a photo to a note or a person. Photos are copied into the app's private storage on your phone.
- Contacts (optional) - only if you tap Import birthdays from contacts. Names and birthdays are read on your phone and are never uploaded.
Google Drive backup (optional)
If you turn on Google Drive backup, you sign in with your Google account. The app asks for permission to use only its own hidden app folder in your Drive. It cannot see, open or change any of your other Drive files. Google shares your email address with the app so it can show which account is connected.
Before upload, each backup is encrypted on your phone with a backup password you choose. Neither we nor Google can read your backups. If you forget the backup password, the backup cannot be restored.
Backups go directly from your phone to your Google Drive. They never pass through our servers. Google's handling of your Drive is covered by the Google Privacy Policy.
Local backup files
You can also export an encrypted backup file and save or share it wherever you choose. Where that file goes is up to you. The app does not send it anywhere on its own.
Advertising
The free version shows ads from Google AdMob. AdMob may collect information such as your device's advertising ID, IP address and device details to show ads, which may be personalised. Where the law requires it (for example in the EEA and UK), you are asked for consent first and can change your choice later in the app's settings. Ads never have access to your diary, family details or reminders. Learn more at policies.google.com/technologies/partner-sites. Upgrading to DiaryKu Pro removes all ads.
Purchases
The DiaryKu Pro upgrade is a one-time purchase handled entirely by Google Play. We never see your payment details. Google Play tells the app only whether Pro has been bought. Google's handling of purchases is covered by the Google Privacy Policy.
Services we use
- Google AdMob - advertising in the free version.
- Google Play Billing - the DiaryKu Pro purchase.
- Google Drive - optional backups, stored in your own Google account.
Children
DiaryKu is a general-audience app and is not directed at children under 13.
Deleting your data
- On your phone: delete items in the app, or clear the app's data or uninstall it to delete everything stored on the phone.
- Google Drive backups: delete them in the app under Settings → Backup, or in Google Drive on the web: Settings → Manage apps → DiaryKu → Delete hidden app data. Uninstalling the app does not delete Drive backups.
- There is nothing stored on our servers to delete.
Changes to this policy
If the app changes how it handles information, we will update this page and the date at the top.
