Privacy policy

What we collect

We do not ask for your name, email or any account. The dates and numbers you enter in a calculator are processed in your browser and are never sent to our servers.

What is stored on your device

• Your light or dark mode choice, so the site opens the way you left it.
• Only if you tick "Save on this device" in the pregnancy calculator: the date you entered, the calculation type and the cycle length, so your week shows when you return. You can remove it any time with the remove link on the home page, or by clearing this site's data in your browser. It is never sent anywhere.
• The ticks you put on the stage checklist in the pregnancy calculator, so they are still there when you return. They stay on your device and can be cleared the same way.

Cookies, analytics and ads

The site itself sets no cookies. If you accept the cookie banner, we load Google Analytics and Microsoft Clarity to measure which pages are used (page views, device type, approximate location, and anonymised interaction recordings). These tools may set cookies and send that usage data to Google and Microsoft. If you decline, neither is loaded. The dates and entries you type into the calculators and the dashboard stay in your browser and are never sent to either tool. We do not currently show advertising; if that changes we will update this page first.

Hosting

The site is served by Cloudflare. Like any host, it processes technical data such as your IP address in standard server logs to deliver the pages and keep the service secure.

Children

Usratak is written for adults and parents. It is not directed at children.

Changes

We may update this policy. The date at the top of the page shows the latest update.
