Privacy Policy
Short version: JSON never leaves the browser. There is no server component, no upload step, and no account to create — no third party has access to the JSON documents processed on this site. The rest of this page covers the specifics.
What data I collect
None that identifies you. jsontoolskit.org is a static site. Every tool on this domain processes your JSON entirely in your browser using JavaScript and WebAssembly. Nothing you drop, paste, or open is transmitted to my servers, because there are no servers handling your file content.
What I don't do
- No accounts. The tools never ask you to register, and none of them work differently if you stay anonymous.
- No analytics scripts (no Google Analytics, no Plausible, no Mixpanel, no Hotjar).
- No tracking cookies. The site does not set any cookies at all.
- No advertising pixels.
- No selling or sharing your data with anyone. If you give us an email address it is used to reply to you about what you asked for, and for nothing else.
Third parties that see your IP
Your browser loads a few assets from third-party CDNs so the site stays small and fast. Those hosts necessarily see your IP address:
- Google Fonts —
fonts.googleapis.comandfonts.gstatic.com, for the Geist and JetBrains Mono fonts. - jsDelivr —
cdn.jsdelivr.net, for the libraries loaded on demand by individual tools (Ajv, js-yaml, jq.wasm, papaparse, jsonrepair, jsonpath-plus, fast-json-patch, json-schema-faker, quicktype, etc.). - Your hosting provider (for jsontoolskit.org) can see standard web-server access logs: IP, user-agent, URL, timestamp. I don't use these logs for anything beyond debugging outages and keep them only as long as the host retains them by default.
None of those third parties see the contents of your JSON documents, because the content never leaves your browser. The library files are static JavaScript / WebAssembly downloads.
Local storage
The tools currently do not write your JSON to localStorage,
sessionStorage, or IndexedDB. The site stores your light/dark theme
preference under the key theme, and — only once you have dismissed or completed the email form — a flag under lead_prompt_v1 so you are not asked twice, both in localStorage. Clear it from the
browser dev-tools any time.
If you give us your email
Some pages offer a form to hear about an offline version, an API, or licensing. It is optional, it is never required to use any tool, and no tool behaves differently if you ignore it.
If you do submit it, we store:
- The address itself, what you asked about, and the page you asked from.
- The date, and the exact consent wording you agreed to.
- A salted hash of your IP address — never the address itself — to show the consent was genuine and to stop the form being flooded.
We email you about the thing you asked about, and nothing else. Your address is never sold, rented, or shared with a third party. Every email carries an unsubscribe link, and you can ask us to delete the record at any time by writing to the address below — we will, without asking why.
