Privacy

This is the shortest kind of privacy policy, because there is very little to describe: the tools on this site run inside your browser.

What we collect

No accounts, and the tools themselves stay in your browser — nothing you type is sent anywhere. Two Google services run on the site: Google Analytics, which shows us which pages are useful, and Google AdSense, which serves the ads that keep the site free. Both set their own cookies. An ad blocker or your browser's privacy settings will stop them, and the tools keep working.

What your browser sends

Loading a page asks our host for a static file. Like any web server, the host sees the request (including your IP address) and keeps short-lived access logs for security and capacity. No cron expression you type is ever part of a request — it is processed locally and only ever appears in your own address bar.

Local storage

The site stores one preference in your browser: your light or dark theme choice. It is read back only to render the page; clearing site data removes it.

Shareable links

A shared link contains the cron expression you built, for example ?expr=*/5+*+*+*+*. That is the whole payload. If you would rather not share a schedule, copy the expression itself instead of the link.

Advertising and analytics

The site is free to run: it carries Google AdSense advertising in the boxes reserved in the layout, and Google Analytics to measure traffic. Both are Google services and set their own cookies; their privacy policies cover what they collect. Any change here ships with this page updated in the same release.
