Cyanotype: Blueprint Photo Lab — Privacy Policy

Effective July 10, 2026

Cyanotype: Blueprint Photo Lab does not collect, store, or transmit any personal data.

In short

• No data collected — the app collects no personal information of any kind.
• No accounts — there is no sign-up, sign-in, or account system.
• No analytics or tracking — no usage analytics, no advertising, no tracking of any kind.
• No third-party SDKs — the app contains no third-party code that could collect data.
• All data stays on your device — the app makes no network connections.

Your photos

All photo processing happens entirely on your device. Photos you choose are accessed only through the system photo picker — which grants the app no access to the rest of your library — and are used solely to render your print. Your photos are never uploaded anywhere. Saving a finished print writes only to your own photo library, with your permission.

Data stored on your device

Your settings (chosen preset and slider values) are stored locally on your device and never leave it. Deleting the app deletes all of its data.

Sharing and selling

Because no data is collected, there is nothing for us to share, sell, or lose.

Changes to this policy

If this policy ever changes, this page will be updated and the effective date above revised.
