Using DiffLists
You may use DiffLists for lawful personal or business purposes. Do not attempt to disrupt the service, bypass security controls, or use the website in a way that infringes the rights of others.
Free service and availability
DiffLists is currently provided without an account or usage fee. Features may be changed, improved, suspended, or discontinued. We do not guarantee uninterrupted availability, compatibility with every browser or file, or permanent access to a particular feature.
Your data
You remain responsible for the data you paste into the tool and for confirming that you have the right to use it. The comparison feature is designed to process list contents locally in your browser. See the privacy policy for details about local processing and ordinary hosting logs.
Accuracy and verification
Results depend on the data and matching options you provide. Case sensitivity, whitespace, delimiters, blank lines, leading zeros, duplicate handling, and source formatting can change the output. Verify important results against the original systems before making legal, financial, medical, security, compliance, or other high-impact decisions.
Acceptable use
Do not use DiffLists to violate law, privacy rights, intellectual-property rights, contracts, platform rules, or security controls. Do not attempt to interfere with the site, distribute malicious content, automate abusive traffic, or misrepresent DiffLists as endorsing your activity.
Educational content
Guides and examples are general educational information. They are not professional legal, accounting, security, compliance, or data-governance advice. Product interfaces and third-party procedures can change, so confirm current instructions with the relevant provider.
Intellectual property
The DiffLists name, site design, original text, and software are protected by applicable intellectual-property laws. You may link to public pages and quote short excerpts with attribution. You may not copy, republish, sell, or create a misleading mirror of the service without permission.
Disclaimer and limitation
DiffLists is provided on an “as is” and “as available” basis, without warranties to the extent permitted by law. To the extent permitted by law, DiffLists is not responsible for indirect, incidental, or consequential losses arising from use of the site or reliance on comparison results.
Changes to these terms
These terms may be updated as the service evolves. The last-updated date will identify the current version. Continued use after an update means the revised terms apply to later use of the service.
