Summary

Lensage is a photography calculator and reference app. We do not collect any personal data. Everything happens on your device. There are no servers, no analytics, no tracking.

What we do NOT collect

We do not collect, store, transmit, or share any of the following:

• Your name, email, phone, or any account information
• Photos, images, or camera data
• Location data sent to any server
• Device identifiers, advertising IDs, or fingerprints
• Usage analytics or crash reports
• Cookies or any tracking technology

Lensage works completely offline. The app makes no network requests.

On-device data

The following stays on your device and is never transmitted:

• Settings & preferences — your selected camera, recently used presets, app appearance — stored locally using iOS standard storage (UserDefaults).
• Location (optional) — if you grant location permission, the app uses your coordinates only to compute sunrise/sunset, moon phase, and astronomical twilight for your location. The data is used in-memory and never saved or sent anywhere. You can deny or revoke this permission anytime in iOS Settings → Privacy & Security → Location Services → Lensage.
• In-App Purchase receipt — when you unlock Lensage Pro, Apple's StoreKit handles the transaction. We receive only a signed receipt from Apple confirming the purchase. We never see your payment details.

Third-party services

Lensage does not integrate with any third-party SDK, analytics provider, advertising network, or backend service.
