Paperless Stamp (hereinafter "the App") does not collect any of your personal information, device information, usage records, document content, stamp images, signature strokes, or contract files. The App requires no account registration, email address, phone number, or any identity credentials. All operations are performed locally on your device, with no internet connection and no data transmission.
The App has no network access permission (no INTERNET permission). It runs completely offline by design, eliminating any possibility of data upload, cloud synchronization, or remote access.
To provide local reading of contracts and saving of stamped/signed documents, the App may request the following permissions, used only locally:
You may revoke storage permission at any time in system settings. Revocation may limit certain functions but will not cause data leakage.
The App does not integrate any third-party SDKs, analytics tools, advertising platforms, or social components. No third party can collect your information through the App. All data processing is done locally on your device.
The App is not directed at children under 13. Since it collects no personal information, there is no intentional or unintentional collection of children's data. Users of all ages can use the App safely.
Because the App collects no data, you have full control over your local files. You can directly delete any contract, stamped copy, or signature file generated or saved by the App using your device's file manager. After uninstalling the App, all temporary data will be automatically erased without any further request.
The App does not collect data, so there is no risk of server-side data breach. We recommend that you properly secure your device (e.g., enable lock screen password, encrypted storage) to prevent unauthorized access to local files.
We may update this Privacy Policy due to legal/regulatory changes or feature adjustments. The updated policy will be shown in new versions of the App, and the "Last Updated" date at the top of this page will be revised. Because the App is completely offline and does not connect to the internet, we cannot push notifications. Please review this page periodically. Your continued use of the App constitutes acceptance of the then-current policy.
If you have any questions about this Privacy Policy, or wish to confirm the zero-data-collection implementation of the App, please contact us at:
