Privacy Policy
Introduction
Welcome to Next JSON. We respect your privacy and are committed to protecting your personal data. This privacy policy explains what data is processed when you visit our website, which third-party services we use, and what your privacy rights are.
Our tools are designed to be privacy-focused: all JSON data you enter is processed directly in your browser and is never stored on or transmitted to our servers.
Your JSON Data
Next JSON is a client-side application. All JSON processing — including parsing, minifying, diffing, schema generation, and format conversion — happens entirely on your local device using JavaScript.
We do not collect, store, or transmit any of the JSON data you input into our tools. Any data you enter is only held in temporary memory while you use the application and is cleared when you close the browser tab or window.
Advertising (Google AdSense)
We use Google AdSense to display advertisements on this website. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this website or other websites.
Google's use of advertising cookies (such as the DoubleClick cookie) 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 may opt out of personalized advertising by visiting Google Ads Settings at https://www.google.com/settings/ads. Alternatively, you can opt out of some third-party vendors' use of cookies for personalized advertising by visiting https://www.aboutads.info/choices.
For more information on how Google uses data when you use our site, please see Google's Privacy & Terms page at https://policies.google.com/technologies/partner-sites.
Cookies
We do not set cookies ourselves for the operation of our tools, and we do not use cookies or local storage to store your JSON data or personal information.
However, third-party vendors — in particular Google AdSense as described above — may set and read cookies on your browser in order to serve and measure advertisements. You can control or delete cookies through your browser settings, and manage ad personalization through the opt-out links provided in the Advertising section.
If you are visiting from the European Economic Area, the United Kingdom, or Switzerland, you will be asked for consent before advertising cookies are used, in accordance with applicable law.
Analytics
We use Umami, a privacy-friendly analytics service, to understand how our website is used (for example, page views and referral sources). Umami does not use cookies and does not collect personally identifiable information; the data it collects is aggregated and anonymized.
Analytics data never includes any of the JSON data you input into our tools.
Your Rights
Depending on where you live, you may have rights under data protection laws such as the GDPR or CCPA, including the right to:
• Access any personal information we might hold about you • Correct any personal information we might hold about you • Request deletion of any personal information we might hold about you • Withdraw consent to personalized advertising at any time
Since we do not collect or store personal data ourselves, requests relating to advertising data are best directed to Google via the links in the Advertising section. For anything else, feel free to contact us using the link below.
Security
We take the security of your data seriously. By processing all JSON data client-side, we eliminate many common security risks associated with server-side processing.
Our website is served over HTTPS to ensure secure communication between your browser and our website, protecting against man-in-the-middle attacks.
