What We Collect

crontools.dev is a fully client-side tool. All cron expression parsing, validation, and next-run calculations happen in your browser — no expression data is ever sent to our servers.

We collect anonymous usage analytics via Google Analytics 4 (page views, general location by country, device type). No personally identifiable information is collected or stored.

Advertising

We display ads via Google AdSense. Google may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising at Google Ad Settings.

Cookies

We use cookies only for Google Analytics and Google AdSense. No first-party cookies are set by crontools.dev itself.
