Lightprint keeps your light recipes on your device. We do not run our own server, require an account, or upload your saved recipes, thumbnails, camera notes, exposure values, calibration settings, or exported cards. In-app purchases are processed by Apple and managed through RevenueCat.
This Privacy Policy explains how Lightprint ("the App", "we", "us", or "our") handles information. Lightprint is an iPhone light meter, exposure recipe, and scene matching tool for photographers and video creators.
| Data | Purpose | Storage |
|---|---|---|
| Light Recipes | Save EV, estimated lux, Kelvin, tint, exposure settings, camera/lens/profile notes, location labels, thumbnails, and setup notes | Device only |
| Project Presets | Remember reusable camera, ISO, aperture, shutter, FPS, shutter angle, and correction settings | Device only |
| Calibration and Correction Values | Apply device or project-specific exposure correction | Device only |
| Preferences | Remember onboarding state, favorites, selected project, and app settings | Device only |
| Exported PNG/CSV Files | Create recipe cards or CSV exports when you choose to export or share | Generated locally |
| Service | Purpose | Data Involved |
|---|---|---|
| Apple App Store | In-app purchase processing, refunds, purchase history, and restoration | Handled by Apple. We do not receive your payment card information or Apple ID password. |
| RevenueCat | Purchase verification and Pro entitlement management | May process technical device/app information, Apple receipt data, purchase status, and anonymous app user identifiers needed to manage purchases. |
We do not use advertising networks, third-party analytics, behavioral tracking SDKs, or third-party crash reporting tools.
| Permission | Purpose | Required |
|---|---|---|
| Camera | Estimate exposure, white balance, Kelvin/tint, and capture local recipe thumbnails | Required for core metering |
Lightprint does not request microphone, contacts, precise location, advertising tracking, or push notification permissions. If you export or share files, iOS may present system share or file dialogs controlled by Apple.
Lightprint Pro is available as a one-time lifetime purchase:
Uninstalling the App removes locally stored app data from your device. Purchase records may remain with Apple and RevenueCat as needed for purchase restoration, fraud prevention, tax, accounting, and legal obligations.
Lightprint does not knowingly collect personal information from children. The App does not include social features, public profiles, chat, advertising, or user-generated content sharing through our servers.
Lightprint may be available worldwide. Core app data is processed locally on your device. Purchase processing may involve Apple and RevenueCat systems in their respective regions.
We may update this Privacy Policy from time to time by updating the "Last Updated" date and posting the revised policy at this URL. Continued use of the App after changes means you accept the updated policy.
