Terms of Use

Last updated: 2026-05-29

1. The short version

These are free, open-source web tools. Use them however you like. No warranty. No liability. The source code is on GitHub under the MIT License.

2. License

The tools on this site are released under the MIT License. You may use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to the conditions in the LICENSE file.

3. No warranty

The tools are provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and noninfringement. In no event shall the authors or copyright holders be liable for any claim, damages, or other liability, whether in an action of contract, tort, or otherwise, arising from, out of, or in connection with the software or its use.

4. No data backup

Anything a tool remembers — settings, inputs, statistics — is stored only in your browser's localStorage. If you clear your browser data, switch browsers, or use a different device, the data does not transfer automatically. Use a tool's export option, where offered, if you want a backup. We have no copy of your data and cannot recover it.

5. Trademarks

Product names, technique names, and trademarks referenced by the tools belong to their respective owners. This site is not affiliated with or endorsed by them, and uses such terms descriptively to refer to the methods or concepts involved.

6. Acceptable use

You agree not to:

  • Attempt to disrupt or interfere with the service
  • Use automated scrapers or bots that load excessive resources
  • Reverse engineer obfuscated portions of the site (there are none, so this is easy)
  • Misrepresent your relationship with this site (you didn't make it, but you can fork it)

7. Third-party services

This site is hosted on Cloudflare Pages. By using the site, you are also subject to Cloudflare's terms of service. If at a future date the site displays advertisements via Google AdSense, you will additionally be subject to Google's terms.

8. Changes to these terms

These terms may be updated occasionally. The "Last updated" date reflects the most recent change. Continued use of the site after changes indicates acceptance of the updated terms.
