Privacy Policy
Last updated: December 29, 2025
Summary
At cron.express, we prioritize your privacy. Our cron expression tool runs entirely in your browser — we never see, store, or transmit your cron expressions. We do collect anonymous analytics data and use advertising services to support the site. This policy explains what we collect, why, and how you can control it.
What We Collect
Tool Usage (None)
The cron expression builder operates 100% client-side. Your cron expressions, timezone selections, and other tool inputs are never sent to our servers. Everything stays in your browser.
Analytics Data
We use Vercel Analytics to collect anonymous, aggregated usage data to understand how visitors use our site. This includes:
- Pages visited and time on site
- Browser type and version
- Device type (desktop, tablet, mobile)
- Country-level geographic region
- Referral source
This data is aggregated and does not identify individual users.
Cookies
We use the following types of cookies:
Essential Cookies
Necessary for basic site functionality, such as remembering your theme preference (light/dark mode). These cannot be disabled.
Analytics Cookies
Used by Vercel Analytics to measure site performance and usage patterns. These help us improve the site.
Advertising Cookies
Set by Google AdSense and other advertising partners to serve relevant ads and measure ad performance. See the Advertising section below for more details.
You can manage cookie preferences through your browser settings. Note that disabling certain cookies may affect site functionality.
Advertising
We display advertisements through Google AdSense to support the free operation of cron.express. Google and its partners may use cookies and similar technologies to:
- Serve ads based on your prior visits to this site or other websites
- Measure ad performance and conversions
- Personalize advertising content based on your interests
- Limit the number of times you see a specific ad
Google's use of advertising cookies enables it and its partners to serve ads based on your visit to cron.express and/or other sites on the Internet.
Opt Out of Personalized Ads
You can opt out of personalized advertising by visiting Google Ads Settings. You can also visit www.aboutads.info to opt out of third-party advertising cookies.
Third-Party Vendors
We work with the following third-party services:
- Vercel: Hosting and analytics (Privacy Policy)
- Google AdSense: Advertising (Privacy Policy)
Each of these services has their own privacy policy governing their collection and use of data.
Data Retention
Since we don't collect personal data from tool usage, there's nothing to retain. Analytics data is retained by Vercel according to their data retention policies (typically aggregated and anonymized). Advertising cookies are managed by Google according to their policies.
Data Security
Our site is served over HTTPS to ensure all communications are encrypted. Since our cron tool operates entirely in your browser, your expressions and data never leave your device. We implement appropriate technical and organizational measures to protect any data processed by our third-party services.
