Privacy Policy

Information collected

None. The app collects, transmits, sells, shares and stores no personal information whatsoever. To be specific, it does not collect:

• Your messages, before or after encryption
• Passphrases, keywords, or public and private keys
• Which ciphers you use, or how often
• Names, email addresses or contact details
• Device identifiers, advertising identifiers or IP addresses
• Location, contacts, photos, calendars or health data
• Usage analytics, telemetry, diagnostics or crash reports

The app requests no permissions from iOS at all — no notifications, no camera, no location, no Face ID, no network.

What the app keeps on your device

Two things, and only two. Neither ever leaves your iPhone, and neither is visible to me or to anyone else.

Your private key, only if you ask

The X25519 sealed box needs a keypair that outlives a single message. Storing that key is off by default. If you switch it on, the private key is written to the iOS Keychain marked WhenPasscodeSetThisDeviceOnly, which means it never syncs to iCloud, never appears in an encrypted backup, and cannot exist at all on a device with no passcode. One tap deletes it.

A count of completed operations

A single number, stored so the app knows when to ask whether you would like to leave a review. It records how many times you have copied a result. It contains no text, no key and nothing about which ciphers you used, and it never leaves the device.

Your messages, passphrases and results are never written to disk under any setting.

Sharing

The app cannot transmit anything by itself. When you tap Share, it hands the result to iOS, which passes it to whichever app you pick. That handoff is always yours to make, and this policy's guarantees end at it: text you share into another app lives by that app's rules, including its backups.

This matters most for a decrypted message. Sharing one into a messaging app puts the plain text into that app's storage, which is exactly what encrypting it was meant to avoid.

The clipboard

When you copy a result, the app places it on the iOS pasteboard with a sixty-second expiry, so iOS clears it on your behalf even if the app is closed. It is also marked local-only, which keeps it off Universal Clipboard so it never reaches your Mac or iPad.

While the app is not in the foreground its content is covered, so a decrypted message does not appear in the app switcher.

Third parties

There are none. The app contains no third-party code, no software development kits, no analytics libraries and no advertising libraries. Every cryptographic algorithm comes from Apple's own frameworks, which are part of iOS rather than something bundled into the app.

Because there is no data and no network, there is nothing to share with anyone, and no data processing agreement to describe.

Children

The app is rated 4+ and collects nothing from anyone, of any age. It has no accounts, no messaging, no user-generated content that reaches a server, and no links out except to this site and the App Store.

Your rights

Regulations such as the GDPR and the CCPA give you the right to access, correct, export and delete the personal data a company holds about you. I hold none, so there is nothing to access, correct, export or delete.

Deleting the app removes everything it ever stored, which is at most the one key you chose to keep and the operations count.

Changes to this policy

If a future version of the app changes what it stores or gains any network capability, this policy will be updated before that version ships, and the effective date above will change. The claims on the app's own About screen are written to match this page exactly.
