JSON Terms of Use
Effective: September 30, 2026
These terms apply to the browser extension JSON Editor (“the extension”), a free personal project provided by SSEM DEV, an independent developer (“the developer”). By installing or using the extension, you agree to these terms. The terms of the store you installed it from (Chrome Web Store or Firefox Add-ons) also apply.
1. Use
- The extension is free, and you may use it for personal and work purposes.
- The extension is distributed through the Chrome Web Store and Firefox Add-ons. Copies obtained elsewhere may have been tampered with — please install from the official stores.
- The open-source components included in the extension are governed by their own licenses, listed in the open-source notices below.
2. Your responsibilities
- The extension keeps only the last document you edited in your browser, and that content is lost when you open a new document or uninstall the extension. Downloading important documents with Save to disk and keeping them safe is your responsibility.
- Check the results of formatting, compacting or converting before applying them to a real service or configuration.
- The Save online menu is left over from the original project and doesn’t work, because the developer runs no server for it. Please don’t rely on it.
3. Disclaimer of warranty
The extension is provided free of charge and “as is”. The developer does not warrant that it will work without interruption or errors, or in every browser and environment, and may change features or stop distributing it at any time. This does not exclude any warranty that cannot be excluded under applicable law.
4. Limitation of liability
The developer is not liable for indirect, special or consequential damages (such as the loss of an unsaved document) arising from the use of, or inability to use, the extension. This limitation does not apply to damage caused by the developer’s intent or gross negligence.
