CaptionPass processes uploaded subtitle files in memory for the duration of a single request on the public converter. We do not persist file contents on disk or in any database.
To enforce the free-tier limit, we increment a coarse per-client daily usage counter (a salted identifier derived from network signals such as the viewer address when present). The counter contains no file contents and resets on UTC calendar days.
Anonymous public converter runs do not save your caption text after the response completes. Pro workspace users may save projects; that data is stored in your account per our terms.
We do not run third-party analytics on this site at the time of writing. If that changes, this page will be updated and the new behavior will go live in the same release.
