SignFast is a PDF signing app that runs entirely on your device. We have intentionally designed it so that we cannot see, store, or transmit your documents, your signatures, or any information about how you use the app.
None. SignFast does not collect, transmit, or store any personal information on any server we control. There are no accounts, no logins, no telemetry, no analytics, no advertising identifiers, no crash-reporting third parties.
The following are stored locally on your device and are never sent anywhere by SignFast:
When you tap to open a PDF, iOS shows the file picker. SignFast can only read files you explicitly choose. We do not have, nor do we request, broad file-system access.
If you buy SignFast Pro (lifetime or annual), the purchase is handled by Apple via StoreKit and the App Store. Apple sends us only an anonymous receipt indicating that a purchase occurred, so the app can unlock Pro features. Your billing information, Apple ID, and payment method are visible only to Apple, not to us. See Apple's Privacy Policy for how Apple handles your purchase data.
SignFast does not embed or call any third-party SDKs for analytics, advertising, crash reporting, or user tracking. The app does not make any network requests during normal use. The only network activity comes from iOS itself (for example, StoreKit during a purchase).
SignFast is a general-purpose utility for signing PDFs and is not directed at children under 13. We do not knowingly collect data from anyone.
If we ever change what SignFast does with data, we will update this page with a new "last updated" date. Because SignFast is offline-first, any future change that involves collecting data would also require a new app version that you would have to choose to install.
