Privacy Policy

Sign & Stamp · Last updated: September 23, 2026

This Privacy Policy explains how Sign & Stamp handles information when you use the mobile application. Sign & Stamp is a PDF stamping tool that lets you add an image stamp to PDF documents and export the result.

Information processed on your device

PDFs, stamp images, and the edited document are processed locally on your device. Sign & Stamp does not upload your documents or stamp images to a server operated by us. Exported files may be placed in the application cache and shared through your device's operating-system share sheet. Temporary files are managed by the operating system and may be removed when the cache is cleared.

Advertising

The free version may show rewarded advertisements provided through Google Mobile Ads (AdMob). The application requests non-personalized ads. Google may still process technical information such as device, app, network, diagnostic, and ad interaction information to provide, measure, and protect its advertising services. Please review Google's Privacy Policy for more information.

Subscriptions and purchases

Sign & Stamp offers optional Pro features through the Apple App Store or Google Play. Subscription status is handled with RevenueCat. We do not receive or store your payment card number. Apple or Google processes payment details under its own privacy policy, and RevenueCat processes purchase and subscription information to provide entitlement management. See RevenueCat's Privacy Policy.

Information we do not collect

Sign & Stamp does not require an account and does not knowingly collect your name, email address, contacts, precise location, or the contents of your documents.

Children's privacy

Sign & Stamp is not directed to children under 13. We do not knowingly collect personal information from children.

Data retention and security

Because document editing is performed on your device, we do not retain your documents on our servers. You are responsible for protecting files stored or shared from your device. Third-party services described above retain information according to their own policies.

Changes to this policy

We may update this Privacy Policy when the application or its services change. The date at the top of this page shows when it was last updated.
