Privacy Policy
Last updated: April 10, 2024
1. Introduction
SleepDepth ("sleepdepth.cloud") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data. By using our website, you agree to the practices described in this policy.
2. Information we collect
Information you provide
We do not require account registration. Our interactive tools (sleep debt calculator, sleep quality quiz, stress score) process data entirely in your browser — no responses are transmitted to our servers or stored.
Information collected automatically
When you visit our site, we may automatically collect:
- Page views and navigation patterns (via anonymous analytics)
- Approximate geographic location (country/region level only)
- Browser type, device type, and operating system
- Referral source (how you arrived at our site)
This information is collected in aggregate and anonymised form. We do not collect personally identifiable information through analytics.
3. Cookies
Our site uses cookies to improve your experience and display relevant advertising. Cookies are small text files stored in your browser.
We use:
- Analytics cookies — to understand how visitors use the site (anonymised)
- Advertising cookies — placed by Google AdSense to serve relevant ads
You can control cookie preferences through your browser settings. Note that disabling cookies may affect site functionality.
4. Google AdSense and advertising
We use Google AdSense to display advertisements. Google uses cookies to serve ads based on your prior visits to our website and other sites on the internet. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to our site and/or other sites on the internet.
You may opt out of personalised advertising by visiting Google Ads Settings. For more information about how Google uses data from sites that use its services, visit Google's Privacy & Terms.
5. How we use your information
We use collected information to:
- Understand which content is most valuable to our readers
- Improve site performance and user experience
- Display relevant advertising
- Analyse site traffic and usage patterns
We do not sell, trade, or rent personal information to third parties.
6. Third-party links
Our articles may contain links to third-party websites. We are not responsible for the privacy practices of those sites. We encourage you to review the privacy policies of any third-party sites you visit.
7. Data retention
Anonymised analytics data is retained for up to 26 months. Tool responses (sleep quiz, stress score) are not stored at all — they are processed locally in your browser only.
8. Your rights
Depending on your location, you may have rights to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Object to processing of your data
- Lodge a complaint with your local data protection authority
As we collect minimal personal data, most requests can be fulfilled simply by clearing your browser cookies.
9. Children's privacy
SleepDepth is not directed at children under 13. We do not knowingly collect information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.
10. Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the site after changes constitutes acceptance of the updated policy.
