Privacy Policy
Last updated: 24 July 2026
Jandira Technologies, LLC (“we”, “us”, “our”) operates Jubarte, which compares Microsoft Word documents and produces tracked-changes redlines. This policy covers the web version at redlines.free, redlines.jubarte.pro and redlines.arthur.law. The macOS application has its own policy at jubarte.pro/privacy.
Your documents stay in your browser. The comparison engine is WebAssembly that runs inside this page, on your own device. The documents you choose are read by JavaScript in your browser and are never uploaded — not to us, not to any third party. We never see them, and no server we operate ever receives their contents, their file names, or their size.
What we do store
The web version gives you a fixed number of free redlines. To count them, and only for that purpose, we store:
-
A random identifier placed in a cookie named
jidon your first visit. It is a randomly generated UUID. It is not derived from you, your device, or anything you do, and it is not linked to any other identifier. - A count of how many redlines that identifier has run, plus the timestamps of the first and most recent one.
That is the entire record: an opaque id, a number, and two timestamps. It contains no name, no email address, no IP address, and nothing derived from your documents. Clearing the cookie detaches you from the record permanently and starts a fresh allowance.
Cookies
We set one cookie, jid, described above. It is strictly necessary to
operate the free allowance and is set with HttpOnly,
Secure and SameSite=Lax. We use no advertising, analytics,
or tracking cookies of any kind.
No tracking or advertising
This site contains no third-party advertising, no advertising identifiers, and no third-party analytics or tracking SDKs. The only external request the page makes is to Google Fonts for the Manrope typeface; every other asset, including the comparison engine itself, is served from our own domain.
Service providers
- Cloudflare, Inc. — hosts this site and the database holding the free-redline counts, and processes connection metadata (such as IP address) as a normal part of serving and protecting the site.
- Google LLC — serves the Manrope web font. Requesting a font discloses your IP address to Google.
Data retention
Free-redline counts are retained only as long as needed to operate the allowance, after which they are deleted. Because the record contains nothing that identifies you, it cannot be connected back to you once the cookie is gone.
Your rights
You can delete the only record we hold about your use of this site yourself, at any
time, by clearing cookies for this domain. If you would prefer us to do it, or want
to know what is stored, write to
support@jubarte.pro — include the
jid value, since without it we have no way to find the row.
Children
Jubarte is a professional productivity tool and is not directed to children under 13.
Changes to this policy
We may update this policy from time to time. The “last updated” date above reflects the most recent revision.
