Privacy Policy
Last updated 29 August 2026
What we collect
Account information you give us (name, email, billing details), the documents you upload for marking, the recipient lists you attach to them, and standard technical logs (IP address, browser, timestamps).
How we use it
To provide the service: marking documents, generating per-recipient copies, and resolving leak checks. Recipient lists are used only to label copies for you, and recipients are never contacted by us.
On paid plans the marks inside a copy carry only an opaque random identifier, never a name or an email, and the mapping from identifier to recipient stays on our servers. The Free plan is the exception: every page of a free copy carries the visible line “Prepared for {recipient} · Do not distribute”, so the label you typed is printed in the file you send.
We do not sell personal data, and we do not use your documents to train models or for any purpose other than serving you.
Documents and retention
Uploaded originals are deleted after marking by default. Marked copies and identifier mappings are kept for as long as your plan retains them, and are deleted when you delete the document. Deleting a document destroys its identifier mapping, after which a leak can no longer be traced.
Storage and security
Files are encrypted in transit and at rest. Access to production systems is limited, logged, and reviewed. Enterprise plans can choose data residency or private deployment.
Your rights
You can access, correct, export, or delete your data at any time. For any privacy request, write to hello@watermark.cx.
