Privacy Policy
DayCal respects your privacy and handles information as follows.
Information we collect
This site has no sign-up or contact form, and does not ask for information that identifies you, such as your name, email address or phone number.
All calculations run in your browser. What you enter is not stored on our server.
URLs that contain calculation conditions
So that results can be shared, the conditions you enter (dates and times, etc.) are part of the page URL. The URL may therefore be recorded in the server access log when the page is opened.
If you send the URL to someone or post it on social media, what it contains is shared too.
Access logs
Our servers (including the hosting provider) may log the URL, IP address, browser type and time of each request. These logs are used only to prevent abuse, handle failures and improve the service, not to identify individuals.
Cookies, analytics and ads
To understand how the site is used and improve it, this site uses Google Analytics (Google LLC) through Google Tag Manager. Google Analytics uses cookies and sends the following to Google.
- What is sent: the address of the page you view (without the calculation conditions), the referring page, the time, the browser and device type, screen size, approximate region and interactions on the page
- Recipient: Google LLC
- Purpose: analysing traffic and improving the site
The calculation conditions you enter, such as dates and times, are not sent to Google. The data is processed statistically and not used to identify individuals. See “How Google uses information from sites or apps that use our services”.
You can stop this collection with the Google Analytics Opt-out Browser Add-on or by disabling cookies in your browser.
This site does not show ads.
Disclosure to third parties
Except for the Google Analytics data described above and disclosure required by law, we do not provide information to third parties.
Changes
We may update this policy when laws or the service change. Updates are announced on this page.
Effective: October 8, 2026
