PDF Signer Privacy Policy

Last updated: November 4, 2026

PDF Signer does not collect, store, transmit or sell any personal data.

Your documents: PDFs are opened, signed and saved entirely within your browser on your device. They are never uploaded to any server.
Your signatures, stamps and settings: these are stored only in your browser's local extension storage on your device. They are never sent anywhere. Uninstalling the extension deletes them.
Website access: the extension checks whether pages you open are PDFs, only so it can offer to sign them. It does not record your browsing history or read page content.
No analytics, ads or tracking: the extension contains no analytics, advertising or tracking code, and makes no network requests other than downloading the PDF you choose to sign.
Third parties: no data is shared with any third party.
