Simple Panorama Viewer

Privacy Policy

This Privacy Policy describes how Simple Pano Viewer ("we", "us", or "our") handles information when you use our desktop and WebGL applications ("Services"). By using the Services, you acknowledge this Privacy Policy.

Last Updated: April 15, 2026

1) Information We Collect

A. Analytics and Diagnostic Data

We use Unity Analytics to collect non-personal usage and diagnostic telemetry, such as app events and performance-related information. Current event categories include:

  • Snapshot actions (take/save/copy)
  • Update button interactions
  • Panorama type statistics (aggregated counts and large-image counts)
  • Auto-panning session duration (aggregated)

This telemetry is used to understand app usage, improve stability, and prioritize product improvements.

B. Platform Analytics

If the app is distributed through Microsoft channels, Microsoft may collect store/platform analytics under its own privacy terms (for example, Microsoft Partner Center reporting).

C. Local App Data Stored On Your Device

To provide core functionality, the app stores data locally on your device:

Desktop:

  • Settings in a local settings.json file under the app's persistent data path
  • Optional exported session files (.spvsession) you explicitly choose to save

WebGL:

  • Settings in browser-backed local storage
  • Image/session state in browser IndexedDB (used as the local source of truth)

D. Session and File Metadata

Session data may include image metadata such as:

  • File name
  • File path (desktop; may contain personal identifiers depending on your OS path)
  • File size
  • Image dimensions
  • Panorama type flags

Important: image contents are processed locally for viewing. We do not intentionally collect or upload your image files to our servers as part of normal app use.

E. Version Check Request (Desktop)

On supported desktop builds, the app may request a public version JSON from:

This is used to determine whether an update is available.

2) How We Use Information

We use collected information to:

  • Diagnose crashes, faults, and performance issues
  • Measure feature usage trends
  • Improve app quality, usability, and performance
  • Restore your previous session and preferences on your device
  • Provide optional session export/import features
  • Notify you when app updates are available

3) Data Sharing

  • We do not sell personal data.
  • Analytics/telemetry is processed by service providers used by the app (e.g., Unity Analytics; and Microsoft under its own platform policies when applicable).
  • We do not share your local session/image files with us or third parties unless you explicitly export and share those files yourself.

4) Data Retention

  • Local settings and local session data remain on your device until you clear app data, remove images/sessions, or uninstall.
  • Desktop session backups are removed when the image list is cleared (PlayerPrefs key deleted).
  • Retention of telemetry handled by third-party analytics providers follows their policies.

5) Your Choices and Controls

You can:

  • Clear your current image/session list from within the app
  • Delete exported .spvsession files manually
  • Clear browser storage (WebGL) via browser controls
  • Uninstall the app to remove local app data (subject to OS/browser behavior)

6) Third-Party Services

Please review applicable third-party policies:

7) Children's Privacy

The Services are not directed to children under the applicable digital age in your jurisdiction, and we do not knowingly collect personal information from children.

8) Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Material updates will be reflected by revising the "Last Updated" date. Continued use of the Services after updates means you accept the revised policy.
