Privacy notice

Last updated: August 10, 2026 · No legal entity has been registered yet — this notice describes current data handling in the absence of an identified operator.

No account, no registration, no email. You do not need to create an account or provide any personal information to use Whatsjson. There is no sign-up, no login, and no way for us to contact you.

What data does Whatsjson process?

URL checking

When you enter a URL and click "Check URL," the following happens:

Your browser sends the URL to the Cloudflare Worker that powers this tool.
The Worker fetches the target URL and analyses the response.
The Worker returns the results to your browser — the diagnostic is displayed on screen and is not stored.
No logs, no databases, no persistent storage. Cloudflare's edge network may retain transient request logs as part of normal operation, but no subscription, user identity, or check history is maintained.

The Worker never follows links, crawls, retries, or sends the URL anywhere else. It makes exactly one fetch to the URL you typed and reports what it received.

Pasted JSON

When you paste JSON text into the tool, parsing happens entirely in your browser. No data leaves your device. The text you paste is never transmitted to any server.

Cookies and tracking

Whatsjson does not set cookies, use any analytics service, or embed third-party tracking. Fonts are loaded from Google Fonts, which receives your IP address when the font files are requested — this is a function of how web browsers load resources, not of any deliberate data collection by this tool.

Third-party services

Google Fonts — Font files are loaded from Google's servers. Google may log your IP address per its own privacy policy.
Cloudflare — The site and Worker are hosted on Cloudflare's edge network. Cloudflare processes requests in transit and may retain transient metadata logs for network operations and security.

Contact

No legal entity has been registered for Whatsjson. There is no support email, no postal address, and no customer service channel. If you have a privacy concern, the operator must register a legal entity and establish a contact method before this notice can list one. This section will be updated when that information becomes available.

Changes to this notice

If this notice changes, the "Last updated" date at the top of this page will reflect the revision. Continued use of the tool after changes constitutes acceptance of the updated notice.
