Cookie policy

The tools directory, tool pages, and API set no cookies on their own. Our own product analytics (which tools are used, how often) is cookie-free — it doesn’t identify you or your browser at all, just counts categorized events. The one exception is described next.

If enabled, a banner asks whether you’ll allow Microsoft Clarity to record session replay/heatmap data to help us improve the tools. Your choice (Accept/Decline) is remembered in your browser’s local storage, not a cookie. Clarity itself only loads, and only sets its own cookies, after you Accept:

• _clck— identifies your browser across visits so a session can be reconstructed for replay. Persists roughly a year.
• _clsk— identifies the current browsing session. Expires after about a day of inactivity.

Everything you type into or see in a tool’s input or output is masked before it ever reaches Clarity, regardless of this choice — see our privacy policy. Declining, or closing the banner without choosing, means Clarity never loads and neither cookie is ever set.

The protected admin area (not publicly accessible) uses a single, secure, HttpOnly, SameSite session cookie to keep an authorized administrator signed in. It is strictly necessary for that feature to function and is not used for tracking.

Declining the session-replay banner (or never accepting it) means the only cookies this site ever sets are the admin sign-in one above, which doesn’t apply to public tool usage. Browser settings can still be used to block cookies entirely if you prefer, or to remove _clck/_clsk after having accepted.
