Terms of Use

The service

DiffViewer is provided free of charge by the site's operators. The tools run in your browser, there is no account, and no payment is asked for or accepted. We may change, add or withdraw tools, and may take the site down for maintenance or permanently, without notice and without owing anyone anything for the interruption.

Acceptable use

Use the tools for anything lawful. Do not use them in support of illegal activity, do not attempt to break, overload or probe the site or the infrastructure serving it, and do not scrape or automate against it in ways that degrade service for other people. Do not copy the site's code or content to pass off as your own product. Beyond that, no permission is needed for any use, personal or commercial.

Provided as-is, with no warranty

The tools are offered exactly as they are, with no promise that they are free of defects, that they will be available at any given moment, or that they will suit your particular purpose. Comparison algorithms have limits and edge cases; parsers meet files they cannot read; browsers behave differently from one another. To the fullest extent the law allows, all warranties, express or implied, are disclaimed.

Comparison results are a review aid

This matters more than the usual boilerplate suggests. A diff shows what differs between two inputs. It does not tell you whether a difference is significant, permitted, or safe, and it cannot certify that two documents are equivalent. A clause comparison is not legal advice. A spreadsheet comparison is not financial, accounting or audit advice.

Before you rely on a comparison for a contract, a filing, a payment, a release or anything else with consequences, have a qualified person check the underlying material. Treat a clean result as a reason to look more closely, never as a substitute for looking.

Limitation of liability

To the extent the law allows, the operators are not liable for any loss arising out of your use of the site — including lost data, lost profits, missed differences, wrongly reported differences, or decisions taken on the strength of a result shown here. Since the service is free and holds nothing of yours, this is less a legal manoeuvre than a statement of what is realistic: you are running software in your own browser, and you are responsible for checking its output before you act on it.

Your content stays yours

You keep every right in whatever you compare. Nothing you paste, open or generate is uploaded, so no licence to it is granted to anyone here — there is nothing for us to license, host, publish or use, and we could not do any of those things even if we wanted to. You are responsible for having the right to work with the material you put into a tool.

The site itself — its code, design, wording and branding — belongs to its operators and is not yours to republish. Output you produce from your own inputs, such as a generated patch file or an exported report, is entirely yours to use.

Advertising and third parties

Pages carry advertising, and ads may link to sites we neither operate nor vet. Anything you do on a destination site is between you and that site, under its terms. How advertising and consent work is described in the privacy policy.

Changes to these terms

These terms may be revised as the site changes. The version published here is the one that applies, and continuing to use DiffViewer after a revision means you accept it. If a court finds any part unenforceable, the rest continues to apply.
