AllJSONTools is a 100% client-side application. All JSON processing, formatting, conversion, and validation happens entirely in your browser. We do not send your data to any server, and we do not store, log, or have access to the content you paste or type into our tools.
Your data is yours. Period.
We want to be explicit about what we do not do:
We do not collect, transmit, or store any JSON data you input into our tools.
We do not require user accounts, sign-ups, or login of any kind.
We do not use cookies for tracking purposes.
We do not sell, share, or monetize any user data.
We do not use third-party analytics trackers.
Every tool on AllJSONTools runs JavaScript directly in your web browser. When you paste JSON into the formatter, convert JSON to YAML, or generate TypeScript interfaces — all of that computation happens locally on your device. No API calls are made, no data is uploaded, and nothing leaves your machine.
AllJSONTools is also a Progressive Web App (PWA), which means you can install it and use it fully offline with no internet connection at all.
AllJSONTools is hosted on Vercel and uses Cloudflare for DNS. These providers may collect basic server access logs (such as IP addresses and request timestamps) as part of their standard infrastructure operations. This data is managed by those providers under their respective privacy policies and is not accessed or processed by us.
AllJSONTools may use your browser's local storage to save user preferences such as theme selection (light/dark mode). This data is stored exclusively in your browser, is never transmitted to any server, and can be cleared at any time through your browser settings.
AllJSONTools does not embed third-party tracking scripts, social media widgets, or advertising networks. If we integrate any third-party service in the future, this policy will be updated accordingly.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically.
If you have any questions or concerns about this Privacy Policy, please reach out via the contact page.
