Tidelock

Privacy policy

Effective 10 November 2026

We collect nothing. Tidelock has no account, no server, no analytics and no tracking. Your photos, videos and files are encrypted on your iPhone and never sent to us. We can't see them, and we can't recover or reset your vault.

What stays on your iPhone

Everything you add to Tidelock is encrypted on your device with keys that only your iPhone (and your recovery key) can open. Thumbnails, file names and album names are encrypted too. We never receive any of it.

Things you can choose to turn on

iCloud Keychain copy of your recovery key. Stored by Apple in iCloud Keychain, which Apple encrypts end to end. Only this key is stored, never your files.
Include vault in iPhone backups. Your iPhone backups (which may be in iCloud) then contain encrypted copies of your vault. They can only be opened with your recovery key.
Backups and Move to new iPhone. Encrypted copies go wherever you choose: a folder, a USB drive, a Mac or AirDrop. We're not involved.
Sharing. When you share an item to another app, that app receives a normal, unencrypted copy and its own privacy policy applies.
Backup reminders. Notifications are scheduled on your iPhone. They never mention what's in your vault.

Purchases

Subscriptions and the Lifetime purchase are handled entirely by Apple through the App Store. We don't receive your name, email or payment details.

Data we collect

None. Our App Store privacy label is “Data Not Collected”.

Children

Tidelock doesn't collect personal information from anyone, including children.

Changes

If this policy changes, we'll update this page and the date above. Tidelock will still never collect your data.

Please never send us your recovery key, PIN or vault files. We can't use them to help, and no one should ask for them.
