Privacy Policy

Overview

Lustra is built with privacy as a core principle. The app is designed to function entirely on your device without requiring an account, cloud storage, or data collection infrastructure. We do not collect, transmit, or sell your personal data.

Data We Do Not Collect

Lustra does not collect:

• Photos or image data
• Location or GPS information
• Usage analytics or behavioral data
• Device identifiers or fingerprints
• Personal information (name, email, contacts)
• Crash reports or diagnostics

On-Device Processing

All photo capture, image processing, depth mapping, and bokeh rendering happen entirely on your device. No images or metadata are transmitted to any server. Your photos are saved directly to your device's photo library and remain under your control.

Camera & Location Permissions

Lustra requests the following system permissions:

• Camera — Required for the app to function. Camera data is processed on-device only and never leaves your phone.
• Photo Library — Used to save captured photos to your library. Lustra does not read or access existing photos.
• Location (optional) — If you enable Geotagging in Settings, your coordinates are embedded in photo EXIF metadata. This data is stored locally in your photo file and is never sent to us.
• Motion (optional) — Used for the horizon indicator viewfinder aid. Motion data is processed in real time and not stored or transmitted.

Third-Party Services

Lustra does not integrate any third-party analytics, advertising, or tracking SDKs. The app does not make network requests during normal operation.

Data Storage

App preferences (such as your selected mode, format, and control settings) are stored locally on your device using standard iOS mechanisms. This data is not accessible to us and is removed if you delete the app.

Children's Privacy

Lustra does not collect data from any user, including children. The app does not require an account and has no social or online features.

Changes to This Policy

If we make changes to this privacy policy, we will update this page with the new effective date. Since Lustra does not collect contact information, we encourage you to review this page periodically.
