Screen Weaver — Privacy Policy

1. Data stored on your device

The app stores the information needed to create, preview, save, and replay screen-based banner sessions. This may include draft text, layout choices, visual style settings, saved presets, display preferences, and local app settings such as automatic maximum brightness.

2. QR sharing and external services

• When you choose online QR sharing, session data is sent to servers operated using Supabase, our hosting and storage provider. This includes banner and sequence text, board layouts, styles, playback timing, mini-game settings and result text, plus share IDs, device positions, app version, and creation and expiry times. We use this data to deliver the shared session to participating devices.
• Anyone with the share link or QR code may access the session while the link is valid, subject to any configured PIN protection. Share it only with intended participants and avoid including sensitive information.
• Online sharing uses HTTPS to protect data in transit. Stored session files are kept in private storage; this does not mean all shared content is end-to-end encrypted.
• Standard share links are valid for 6 hours. Review or support links may have a different validity period. After a link expires, it can no longer be opened, and the server records and stored files for that share are deleted automatically, usually within about 2 hours of expiry.
• To request deletion of a shared session, email [email protected] with the share link so we can locate the data. Deleting presets, clearing app data, or uninstalling the app does not delete server copies or copies already received by participants.
• When a participant scans a QR code, camera frames are used for scanning and are not uploaded to Sunlit Water servers by the app.
• When you open this privacy policy, the support page, or email support, your browser, email app, and hosting infrastructure may process normal request metadata.

3. Third-party analytics and advertising

We use Google AdMob to display advertisements and Google Analytics for Firebase to understand app usage, which helps us improve the app experience.

• These third-party services use device identifiers (such as Android Advertising ID or iOS Advertising Identifier), cookies, and similar technologies to collect and process usage data.
• Personalized Advertising: Google and its partners use this data to serve personalized ads based on your prior use of this app or other apps and websites.
• For more detailed information on how Google collects and processes data, please visit: How Google uses information from sites or apps that use our services.

4. Why this data is used

• To preview and display banner content on one or more devices.
• To save and restore presets you choose to keep on the device.
• To assign participant device positions and synchronize the display flow through QR payloads.
• To keep the screen readable during banner playback, including brightness-related preferences.

5. Current app details

• No mandatory account registration or sign-in flow.
• Online QR sharing requires internet access to upload and retrieve session data. Local preview and playback can be used without creating an online share.
• Camera permission may be needed for participants to scan host QR codes.
• The app does not include persistent background location collection.

6. Your controls

• You can decline camera permission, although QR scanning will not work without it.
• You can delete saved presets and local app data from the app or operating system controls.
• You can avoid uploading session data by using local preview or playback without online QR sharing.
• Ads and Analytics Opt-Out: You can manage or opt out of personalized advertising and analytics tracking through your device's privacy settings (e.g., "Opt out of Ads Personalization" or "Delete advertising ID" on Android, and "Limit Ad Tracking" on iOS).
