Privacy Policy
Last updated: November 12, 2026
This policy explains what information FormatJson (https://www.formatjson.com) collects, how it is used, and the choices you have. If you have questions, email support@formatjson.com.
Data you paste into our tools
The JSON editor, XML formatter, UUID generator, Base64 encoder and User-Agent parser run entirely in your browser. The data you paste or upload into them is processed on your device and is not sent to or stored on our servers.
If you turn on "Save to Local Storage" in the JSON editor, your content is saved in your browser's local storage on your device only. You can turn it off at any time, which removes the saved content.
When you share JSON with the share feature, the data is compressed into the link itself. Anyone who has the link can read the data, so don't share links that contain secrets.
GraphQL Client
Browsers block many cross-origin requests, so requests you send from the GraphQL Client are forwarded through our server to the URL you enter. The request (URL, headers and body) and the response pass through our server so they can be delivered to you. We do not store them or use them for any other purpose. Your query history is kept in your browser's local storage, not on our servers.
IP Lookup
The IP Lookup tool sends the IP address you look up (or, if you look up your own, your public IP address) directly from your browser to third-party geolocation services, currently ipapi.co and ipinfo.io. Their privacy policies apply to that request.
Advertising and cookies
We use Google AdSense to show ads, which keeps the tools free.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
- You can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
- Learn more about how Google uses information from sites that use its services and how Google uses cookies in advertising.
Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before personalized ads are shown. You can also block or delete cookies in your browser settings; the tools keep working without them.
Our own use of browser storage is limited to remembering your settings, such as your cookie choice and the "Save to Local Storage" option.
Server logs
Like most websites, our hosting provider (Cloudflare) processes standard technical information such as IP address, browser type and the pages requested, in order to deliver the site and protect it from abuse.
Your rights
Depending on where you live, including under the GDPR in the EU/UK and the CCPA in California, you may have the right to access, correct or delete personal information about you, and to object to or limit certain processing. We do not sell personal information. To exercise these rights for data held by us, email support@formatjson.com. For advertising data held by Google, use the links above.
Children
FormatJson is not directed at children under 13, and we do not knowingly collect information from them.
