Your documents stay on your device. PDFs, photos, signatures and stamps are processed locally and are never uploaded. Sigvo shows no ads and needs no account. To keep the app stable and improve it, Sigvo uses Google Firebase for anonymous crash reports and usage analytics — this never includes your documents, and no advertising ID is used.

- App settings such as language and theme
- Your PDFs and photos (processed on-device only, never uploaded)
Google Play Games (Optional)
- Firebase Crashlytics — anonymous crash reports
- Firebase Analytics — anonymous usage analytics (no advertising ID)
