Document processing
WatermarkPDF does not receive, upload, or store the PDFs, images, signatures, stamps, watermark text, or redaction selections you use in the editor. Processing happens in browser memory.
Local storage
Recent watermark reasons may be stored in your browser. Signatures and stamps are session-only unless you explicitly choose “Remember on this device,” in which case they are stored in IndexedDB on that device. Use “Clear all saved data” to remove these records.
Public-site data
The public site currently uses no analytics, advertising, accounts, contact forms, or cookies. This policy must be updated before any of those features are introduced.
Hosting logs
Like most static hosting and network providers, Vercel and Cloudflare may process routine request information such as IP addresses and user-agent strings to deliver and secure the site. Those requests fetch application assets; the editor does not transmit document contents.
