KitJade

Privacy Policy

A plain description of what this site processes, where it goes, and what you can control.

Last updated:

This policy explains how KitJade handles information when you use this website. It is written to describe the actual behaviour of the site, not to make broad promises. If something is not clear, ask [email protected].

1. Information you enter into tools

Developer, PDF, image and calculator tools run in your browser. Values you paste or files you select are processed locally with JavaScript and are not transmitted to a KitJade server. Closing or reloading the page discards them. We do not maintain accounts, so we cannot retrieve a file or input later.

Network tools may contact third-party services because the data is inherently public. The page for each tool states which service is used:

  • DNS lookup sends the hostname and record type to Cloudflare DNS-over-HTTPS (1.1.1.1) or Google Public DNS, with automatic fallback.
  • Public IP lookup contacts ipwho.is and may fall back to api.ipify.org. Those services see the IP address of your connection, as any website does.
  • SSL certificate checker queries Cert Spotter's Certificate Transparency API, using the hostname you enter. It may also make a live HTTPS request through the KitJade Worker to confirm reachability.
  • HTTP header checker sends the URL you enter to the KitJade Worker, which fetches the response headers only. The request body is not returned to your browser.
  • MAC address lookup sends the MAC address or OUI to the KitJade Worker, which queries a public vendor database and caches the result briefly.
  • WHOIS and domain expiry send the domain to the KitJade Worker, which queries the RDAP endpoint published by IANA for the responsible registry.
  • BGP prefix lookup sends the IP or prefix to the KitJade Worker, which queries RIPEstat (RIPE NCC).
  • Currency converter asks the KitJade Worker for European Central Bank reference rates republished by Frankfurter; the currency code is sent, not personal data.
  • Internet speed test exchanges generated download and upload data with Cloudflare's public speed endpoint and reads the reported edge location. No file from your device is sent, and no test history is stored.

The AI background remover is different: your photo stays in the tab and is not uploaded. On first use the browser downloads the MODNet model from Hugging Face and a WebAssembly runtime from jsDelivr; those hosts receive the file request, not the image.

Do not submit information you are not authorised to share. A hostname is often public; an internal hostname or an unannounced URL may not be.

2. Information processed automatically

Like any website, the hosting provider processes request metadata needed to deliver pages and protect the service, including IP address, user agent, requested URL, timestamp and basic network information. This site is hosted on Cloudflare Pages and uses a Cloudflare Worker for API requests. Cloudflare processes this data under its own privacy terms.

The Worker keeps a short-lived, in-memory request counter per isolate to apply rate limits. It is not a user profile and is not persisted beyond the isolate lifecycle. Application-level logging of tool inputs is not enabled.

3. Cookies and local storage

The tools themselves do not need cookies. Two values are stored in your browser's local storage:

  • kitjade-theme remembers light or dark mode.
  • kitjade-consent remembers whether you accepted or declined optional analytics and advertising.

Optional third-party cookies are loaded only after you choose “Accept all”. Advertising is provided by Google AdSense when a publisher ID is configured. Analytics may use Google Analytics 4 (with IP anonymisation requested) and/or Cloudflare Web Analytics, which is cookieless. You can change your choice at any time using or by clearing site data in your browser.

4. Why we process information

  • To deliver the website and its tools, and to keep them secure and available.
  • To respond to messages you send us.
  • To measure aggregate usage and fund the site, only where you have consented.
  • To comply with legal obligations and enforce our terms.

5. Sharing

We do not sell personal information. Data is shared only with service providers needed to run the site (hosting, DNS, advertising and analytics as described above), or where required by law. The specific third-party lookups listed in section 1 receive the values you choose to submit to those tools.

6. Retention

Tool inputs are not stored by us. Hosting and analytics data are retained according to the provider's configuration and policies. Support emails are kept only as long as needed to resolve the issue and meet legal obligations.

7. Your choices and rights

Depending on where you live, you may have rights to access, correct, delete or restrict processing of your personal data, or to object to certain processing. Because we do not hold accounts or tool inputs, many requests will relate to hosting logs or analytics. Contact us and we will explain what can be done. You can withdraw cookie consent at any time without losing access to any tool.

8. Security

The site uses HTTPS. The Worker validates outbound targets to reduce server-side request forgery, blocks private and metadata addresses, applies timeouts and response size limits, and restricts CORS to this site. No system is perfectly secure, and browser-based source code cannot be completely hidden. Do not treat this site as a store for confidential documents.

9. Children

The site is intended for general professional and personal use and is not directed at children. We do not knowingly collect personal information from children.

10. Changes and contact

Material changes will update the date at the top of this page. Questions or requests can be sent to [email protected]. See also the cookie policy and terms of use.
