The short version
The tools on this site run entirely in your browser. Anything you type or paste into them is processed locally on your machine by JavaScript and is never sent to, stored by, or visible to us. We run no analytics. The only third parties involved are our hosting provider (Cloudflare) and our advertising provider (Google AdSense), described below.
What we collect
Tool inputs: None. Every tool on this site runs entirely client-side; we do not transmit or store the passwords, configs, IP lists, logs, or other strings you paste into the tools, and no tool makes an outbound network request with your input.
Analytics: None. We do not use Google Analytics or any other analytics or tracking service. We see only the aggregate, non-identifying traffic counts our hosting provider reports.
Server logs: The site is served by Cloudflare. Like any web host, Cloudflare processes standard connection data (IP address, requested page, timestamp, user-agent) to deliver the site and protect it against abuse. We do not receive or keep per-visitor logs ourselves. Cloudflare's handling of this data is described in the Cloudflare Privacy Policy.
Browser storage: We store two small values in your browser's local storage: your dark/light theme preference and a flag recording that you dismissed the cookie notice. Neither contains tracking identifiers or tool inputs, and neither is sent anywhere.
Advertising (Google AdSense)
This site is funded by advertisements served by Google AdSense. Google and its partners use cookies and similar technologies to serve ads, measure their performance, and, where you have consented, to personalize ads based on your visits to this and other websites.
If you visit from the European Economic Area, the United Kingdom, or Switzerland, you will be shown a consent message before any advertising cookies are set, and you can choose non-personalized ads. You can also opt out of personalized advertising at any time at Google Ads Settings. For details on how Google uses data from sites that show its ads, see How Google uses information from sites or apps that use our services.
Third-party services
Cloudflare hosts and serves this site, as described under "Server logs" above, and is the only infrastructure provider with any technical visibility into site traffic.
No tool on this site makes a network request with your input. You can verify this yourself with your browser's developer tools: open the Network panel, use any tool, and watch nothing go out.
Your rights
Depending on where you live, you may have rights under the General Data Protection Regulation (GDPR), UK GDPR, the California Consumer Privacy Act (CCPA/CPRA), or similar laws, including the right to access, correct, or delete personal data. Because we do not collect or store personal data or tool inputs ourselves, in most cases there is nothing for us to look up or delete. For data processed by Google (advertising) or Cloudflare (hosting), the links above lead to their own privacy controls. For anything else, contact us via the Contact page and we will respond promptly.
Children
This site is a technical reference aimed at IT professionals. It is not directed at children under 13, and we do not knowingly collect personal information from anyone.
Changes to this policy
If we change this policy (for example, if we add a new third-party service), we will update this page and the date at the top. Material changes will be noted here.
