Privacy Policy
Last updated: 10 September 2026
The short version: the text you paste never leaves your browser. There is no server to send it to. We don't have accounts, we don't use analytics, and we don't set advertising or tracking cookies.
How the tool works
OpenKOD Diff Checker is a static website. All of the comparison work — reading your text, computing the differences, applying merges — happens in JavaScript running on your own device. The content you paste into either panel is not transmitted anywhere, is not written to any database, and is not visible to us or to anyone else.
What is stored on your device
One item is saved in your browser's local storage: your light or dark theme preference, so the site looks the same next time you visit. It stays on your device, is readable only by this site, and you can remove it at any time by clearing site data in your browser. Nothing else is stored, and no cookies are set.
Shareable links
The Share button compresses your comparison into the part of the URL after the
# symbol. Browsers never transmit that fragment to a web server, so
generating a link does not upload your text. Two things are still worth knowing:
- Anyone who receives the link can read the text it contains. Treat a share link the same way you would treat the content itself.
- The link may be recorded wherever you paste it — your browser history, a chat app, an email, a ticket — and we have no control over those places.
Don't create share links from confidential material you wouldn't want copied.
Server logs
The files that make up this site are delivered by a hosting provider. Like essentially all web hosts, that provider may automatically record standard request information — IP address, timestamp, which file was requested, browser user-agent — for security and reliability. That is a function of the hosting infrastructure, not something this site collects or uses, and it never includes the text you compare, because that text is never sent.
Third parties
The site loads no third-party scripts, fonts, trackers, advertising or embedded content. Everything it needs is served from this domain. Nothing about your visit is shared with any other company.
Children
The site is a general-purpose utility and is not directed at children. Because no personal information is collected from anyone, none is collected from children either.
Your rights
Data protection laws such as the GDPR give you rights to access, correct or delete personal data held about you. We hold none, so there is nothing to retrieve or erase. The only data connected to your use of the site lives on your own device, and clearing your browser's site data removes it.
Changes
If this policy changes, the revised version will be posted here with a new date at the top. Material changes to how the site handles information will be described rather than quietly substituted.
