Privacy Policy
Last updated: November 9, 2026
Summary: The Pairwise Comparison Tool runs entirely in your browser. The options you enter, your comparisons, and your rankings are never transmitted to our servers. We do not require accounts and we do not sell your data.
1. Data We Process
Your comparison inputs — item names, comparison choices, weights, and generated rankings — are processed locally in your browser's memory and, optionally, stored in your browser's local storage or encoded in the page URL. This data is not sent to us.
2. Local Storage
We use your browser's local storage to remember preferences such as your light or dark theme choice and to preserve a working comparison session. You can delete this at any time by clearing your browser's site data.
3. Cookies
The tool does not set advertising or analytics cookies. Any storage used is strictly functional and necessary for the tool to work as expected.
4. Third-Party Services
We load web fonts from Google Fonts. When your browser requests these fonts, Google may receive standard technical information such as your IP address and browser type. We do not control Google's data practices; please review Google's privacy policy for details.
5. Sharing Links
If you choose to share a comparison, the relevant data is encoded in the URL itself. Anyone with the link may be able to view that data. Do not share links containing confidential information.
6. Children's Privacy
The tool is not directed to children under 13, and we do not knowingly collect personal information from children.
7. Your Rights
Because we do not collect your comparison data, most access, correction, and deletion requests can be fulfilled by clearing your browser's local storage. For any other privacy question, contact us at support@comparisonpairwise.com.
8. Changes to This Policy
We may update this policy from time to time. Material changes will be reflected by the "last updated" date above.
