What our calculators do with your inputs
Our calculators run in your browser. The times and answers you enter are used to show your result and are not sent to us or stored on our servers.
Analytics (Google Analytics 4)
We use Google Analytics 4 to understand how visitors use the site, for example which pages are popular, approximate location (country or city), device and browser type, and how you arrived. Google Analytics uses cookies and similar technologies. Google processes this data under its own privacy policy. You can opt out with the Google Analytics opt-out browser add-on.
Cookies
Cookies are small files stored in your browser. We use:
- Analytics cookies (Google Analytics 4, such as
_ga) to measure site usage. - Essential cookies set by WordPress or our caching system so the site works properly.
You can block or delete cookies in your browser settings. The site will still work.
Advertising
CircadianIQ may show ads from third-party ad networks such as Google AdSense. These providers, including Google, may use cookies or similar technologies to show ads based on your visits to this and other websites. You can turn off personalised Google ads at Google Ads Settings, and opt out of many third-party vendors at aboutads.info or youronlinechoices.eu. Learn more at how Google uses information from sites that use its services.
Affiliate links
Some links are affiliate links. When you click one, the partner may set a cookie to track that the visit came from CircadianIQ, so we may earn a commission at no extra cost to you. You can avoid this by blocking or clearing cookies.
Hosting and server logs
CircadianIQ is hosted by Hostinger. Like most hosts, their servers may record technical data such as IP address, browser type and the pages requested, for security and performance. See Hostinger’s privacy policy.
Emails and forms
If you email us or sign up for a guide or newsletter, we use your email only to reply or send what you asked for. You can unsubscribe at any time. If we run a newsletter, your email is stored with our email service provider only to send it, and every email includes an unsubscribe link.
We do not sell your data
We never sell, rent or trade your personal information. We share data only with the service providers above (Google, Hostinger) to run the site, or when the law requires it.
Your rights
You may ask us to access, correct or delete personal information we hold about you. Email pakbrain.ai@gmail.com and we will respond within a reasonable time.
Children
CircadianIQ is not directed at children under 13, and we do not knowingly collect their personal data. Parents using the baby sleep tool enter only schedule information, which stays in the browser.
Changes
We may update this policy. The “Last updated” date above shows the latest version.
