Privacy Policy
Last updated: April 14, 2026
Overview
CronWizard ("we", "our", or "us") operates https://cronwizard.com (the "Service"). This Privacy Policy explains what information is collected when you use the Service, how it is used, and the choices you have.
CronWizard is a free, client-side cron expression generator and validator. Cron expressions you build or validate are processed in your browser and are not stored on our servers.
Information We Collect
Information you provide
We do not require you to register, sign in, or submit personal information to use CronWizard. Cron expressions, schedules, and preferences you enter stay in your browser and are not transmitted to us.
Automatically collected data
When you visit the Service, your browser automatically sends certain information such as your IP address, browser type, device type, operating system, referring URL, and pages visited. We use this information only in aggregate form to improve the Service.
Local storage
CronWizard uses your browser's local storage to remember your preferences (for example, theme and timezone selection). This data never leaves your device.
Cookies and Analytics
We use the following third-party services that may set cookies or collect anonymized usage data:
- Vercel Analytics — privacy-friendly, cookie-less page view and performance metrics. Learn more at vercel.com/legal/privacy-policy.
- Google AdSense — displays advertisements on the Service. Google may use cookies to personalize ads and measure effectiveness. You can opt out of personalized advertising at google.com/settings/ads. See Google's advertising policies at policies.google.com/technologies/ads.
- Google Search Console — we use the Search Console verification tag to monitor our site's search performance. No personal data is shared with us from this service.
Third-Party Advertising
Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites on the internet. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendor use of cookies for personalized advertising by visiting aboutads.info.
Data Sharing
We do not sell or rent personal information. We only share data with the third-party processors listed above (Vercel, Google) to operate the Service.
Children's Privacy
CronWizard is a developer tool not directed at children under 13. We do not knowingly collect personal information from children under 13.
Your Rights
Depending on your jurisdiction (for example, GDPR in the EU/UK or CCPA in California), you may have rights to access, correct, or delete information about you. Because CronWizard does not collect personally identifiable account data, these rights are primarily satisfied by clearing your browser's local storage and cookies.

We may update this Privacy Policy from time to time. The "Last updated" date at the top of the page reflects the most recent revision.
