CIPHERKIN / PRIVACY

Privacy, with clarity.

Last updated 20 October 2026. This policy covers the Cipherkin app for iPhone and iPad, published by Black Well Foundry LLC, and this website.

The short version

Cipherkin collects nothing. It has no accounts, ads, analytics or tracking, and no servers of its own. Your notes and passwords stay on your device and aren’t saved.

What the app handles, and where it goes

• Notes and passwords exist only in the app’s memory while you write or read. Cipherkin doesn’t save drafts, passwords, opened notes or any history, and clears them when you leave the app.
• Sealed messages go only where you send them: you copy or share the sealed text yourself, through apps you choose. Those apps handle it under their own policies, and Cipherkin can’t delete copies held there.
• The clipboard is read only when you tap Paste. Text you copy from an opened note stays on this device and clears from the clipboard after five minutes.
• Settings: the app stores only whether sounds are on and the last theme you used, on your device.
• Purchases are handled entirely by Apple through the App Store. Cipherkin learns only whether the unlock is owned on this device, and never sees your payment details or Apple Account.

Free notes aren’t private

Free Classic Cipher notes are sealed with a password built into every copy of Cipherkin, so anyone with the app can open them. They’re for fun, not for secrets. With the one-time unlock you can set your own password; only someone who knows it can open that note. Short or common passwords can be guessed by someone who has the sealed text, so use a longer one for anything that matters.

Children

Cipherkin collects no personal information from anyone, including children.

This website

This site has no analytics, advertising trackers, accounts, forms or cookies. Its theme preview runs in your browser and doesn’t handle real messages. Our hosting provider may process standard request information, such as IP addresses and access logs, under its own policies.

Changes

If this policy changes, the new version will appear on this page with a new date.
