SightFrame is designed around on-device processing. We do not collect, upload, sell or track user data.

  1. We do not collect data

SightFrame does not collect, upload, share or sell personal information, device identifiers, precise location, contacts, photos, health data or usage analytics. The app contains no advertising, third-party analytics SDKs or cross-app tracking.

  1. Camera and image processing

The app requests camera access only when you choose to use live vision simulation. Camera frames are processed in real time on your device to create visual effects for myopia, astigmatism, presbyopia and related experiences. Frames are not sent to the developer or to any third-party server.

  1. Photos and screenshots

The app uses system photo or sharing features only when you explicitly save or share an image. Saved content is managed by iOS; the app does not read or upload your photo library in the background.

  1. On-device storage

Language, appearance and feature preferences, vision self-test records, and local statistics may be stored on your device to improve future sessions. This data does not leave the device. Deleting the app normally removes this local data.

  1. Children’s privacy

The app is not directed specifically to children and we do not knowingly collect personal information from children. Because the app collects no user data, children do not transmit personal information to us through the app.

  1. Health information

SightFrame provides vision simulation, general self-test assistance and eye-health education. It is not a medical diagnosis, treatment recommendation or professional eye examination. Consult a licensed eye-care professional if you have vision concerns or discomfort.

  1. Changes to this policy

If app functionality or data practices change, we will update this page and its effective date. Material changes will be explained where appropriate.

  1. Privacy questions
