Mark a copy
Upload an image, PDF, or other supported file and assign a private identifier. Download the marked copy. That is the file you share.
Contract
Mark the contract before it goes out.
Trace that copy.
Before a contract goes to the other side, mark that copy. Markedfile is forensic watermarking and document tracking: an invisible watermark on the file you send, then leak detection and leak tracing if that copy gets out. The same mark is content protection and data leak prevention for a document that was supposed to stay with one recipient. File contents are not stored.

Send the marked file
Name the other party in the identifier. Download the marked contract and send that file, not the original. If a copy later appears, detection looks for the surviving mark. Recovery is best effort. It does not by itself name a person, and a heavily edited copy can miss.
How forensic watermarking works here
Keep the record
The account stores the identifier, not the file. You can see each active mark and delete a record when you want the slot back.
Check a suspected copy
Upload a copy or a screenshot. Leak detection looks for a surviving mark. Recovery is best effort and depends on the file and what happened to it.
File contents are not stored
Bytes are processed in memory and are not written to disk. The account keeps the identifier, the file name and type, status, and timestamps, plus a detection token while the file is active.
Pricing
Prices are USD per month. Free, Pro, and Unlimited apply only to your Personal Workspace. Enterprise applies to one shared workspace, and a personal plan does not cover it. An active file is one whose mark can still be detected. This is a cap on active files, not a monthly upload quota.

Questions
What is an invisible forensic watermark?
An invisible forensic watermark is a mark embedded in a file so it is not meant to be noticed in ordinary viewing. You assign a private identifier — a person, a company, a deal, or a recipient — and Markedfile embeds that mark in a copy you can share. The mark is not the product name. If that copy later turns up, detection looks for the mark that belongs to the identifier.
What does Markedfile store?
File contents are processed in memory and are not stored. Your account keeps the metadata needed to detect a mark later: the identifier you assigned, the file name and type, the status, and timestamps. A file stays detectable while it is active. Deleting the record ends detection and frees the slot. Letting a Free file expire also removes the token. Passwords are stored as hashes.
What is included in Free, and when does a file expire?
Free is the Personal Workspace plan. It includes 5 active files. Each stays detectable for 6 calendar months from the time you mark it, clamped to the end of shorter months. Deleting the record ends detection and frees a slot immediately. This is a cap on active files, not a monthly upload quota.
How do personal plans differ from a business workspace?
Free, Pro, and Unlimited apply only to your Personal Workspace. That workspace cannot be shared or invited into. Business collaboration uses a shared workspace on Enterprise. A personal plan does not grant files or invitations there. You can create a shared workspace without paying, so there is something to subscribe, but invitations and new marks on that workspace need an active Enterprise subscription. Enterprise is per workspace.
Will every screenshot or edited copy be identified?
No. Recovery is best effort, and the confidence score is a heuristic. Images can often survive a crop, a resize, or recompression, but a heavily edited copy may not resolve. Marks in text files and ZIP-based packages, including Office files, are fragile. Markedfile does not promise that every leaked copy can be traced.
Which files can be marked?
PNG, JPEG, and WebP images; PDFs, including detection from the rendered page rather than metadata alone; text files and ZIP-based packages, including Office files; and other binary files, which come back inside a marked ZIP. The workspace plan sets the limit: Free allows 5 MB per file and PDFs up to 10 pages, Pro 10 MB and 50 pages, Unlimited 20 MB and 100 pages, and Enterprise 100 MB and 500 pages.
