Signly collects no user data. Signatures, stamps and photos are stored only in the browser's local extension storage on your device and are never transmitted. Background removal and document signing run entirely locally. There are no analytics or trackers. The only network request the extension can make is validating a Pro license key (entered by the user) against our payment provider, Polar — no keys are on sale in this version.
