Privacy Policy

Summary: SonicCanvas is a fully offline, privacy-first audio-driven painting app. We do not collect, store, or transmit any personal information. All audio analysis and artwork rendering happen entirely on your device.

1. Introduction

This Privacy Policy describes how SonicCanvas ("we", "our", or "the App") handles information when you use our mobile application. SonicCanvas turns the sound around you — your voice, music, or ambient noise — into real-time generative paintings. It is designed to work entirely on your device: no account, no server, no tracking.

2. Information We Collect

All artworks, recorded videos, and app preferences are stored locally on your device and are never transmitted anywhere.

3. Microphone Permission

SonicCanvas requests access to your device microphone to analyze live audio — volume, frequency, pitch, and timbre — and convert it into painting effects in real time. This is the core functionality of the app. All audio captured by the microphone is processed locally on your device using on-device signal processing (FFT, autocorrelation pitch detection, spectral analysis). The audio stream itself is not recorded or stored during normal painting; it is analyzed in memory and immediately discarded.

The only time audio is saved is when you explicitly start a screen recording of your creative session — in that case the ambient sound is included in the video, which is stored only on your device (see Section 4).

You can revoke microphone permission at any time in iOS Settings → Privacy & Security → Microphone.

4. Artworks and Screen Recordings

SonicCanvas lets you capture your painting as a JPG image and record your creative process as a video (including the ambient audio that drove the painting). All captured images and recorded videos are stored exclusively on your device, in the app's local work library. If you choose, copies are also saved to your iOS Photos library. You can rename or delete them at any time within the app. Nothing is ever uploaded or transmitted to any server.

5. Photo Library Permission

SonicCanvas requests add-only access to your Photos library, used solely to save the images and videos you export. The App cannot read, browse, or modify your existing photos. You can revoke this permission at any time in iOS Settings → Privacy & Security → Photos.

6. Data Storage

All data generated by the App (artworks, videos, titles, app preferences) is stored exclusively on your device using local files and iOS system storage (SwiftData and UserDefaults). Uninstalling the App will permanently delete all locally stored data, except the copies you exported to your Photos library.

7. Third-Party Services

SonicCanvas does not integrate any third-party analytics, advertising, crash-reporting, or social login services. No data is shared with any third party.

8. Children's Privacy

SonicCanvas does not collect personal information from anyone, including children under the age of 13. The App is rated 4+ on the App Store and is safe for all ages.

9. Your Rights (Including CCPA)

Because we collect no personal data, there is nothing for us to access, correct, sell, or delete on our end. For California residents, this means SonicCanvas fully complies with the California Consumer Privacy Act (CCPA): we collect no personal information and therefore sell or share none. All your data lives on your device and can be removed by deleting items in the work library or simply uninstalling the App.

10. Changes to This Policy

We may update this Privacy Policy occasionally. Any changes will be posted on this page with a revised "Last Updated" date. We encourage you to review this page periodically.
