SleepQuify is committed to protecting your privacy. This policy explains clearly what data we collect, why we collect it, and how we use it. We keep this simple because we have nothing to hide.
SleepQuify is a free sleep calculator website operated as part of the Quify Group. Our website is located at sleepquify.com. If you have questions about this privacy policy you can contact us at hello@sleepquify.com.
SleepQuify is designed to work without collecting personal information. Here is exactly what happens when you use the site.
When you use the sleep calculator you enter a time and an offset. This information is processed entirely in your browser and is never sent to our servers. We do not store, log, or retain any calculation inputs.
When you ask Luna a question your message is sent to the Anthropic API to generate a response. Anthropic processes this request according to their own privacy policy. We do not store your questions or Luna's responses. Each session is independent and no conversation history is retained between visits.
Like all websites, our server automatically receives standard technical information when you visit including your IP address, browser type, device type, pages visited, and time of visit. This information is used for security monitoring and aggregate analytics only. It is not linked to your identity.
SleepQuify uses cookies in two ways.
These are required for the site to function. They do not track you across other websites and do not collect personal information.
We use display advertising to keep SleepQuify free. Advertising networks including Google AdSense may set cookies on your device to show relevant advertisements. These cookies may track your browsing behaviour across websites to personalise ads.
Your choices. You can opt out of personalised advertising at any time through the Google Ads Settings page at adssettings.google.com or through the Network Advertising Initiative opt-out tool. You can also manage cookies through your browser settings.
SleepQuify is a free service supported by display advertising. We use Google AdSense and may use other advertising networks to display advertisements on the site.
These advertising partners may use cookies and similar tracking technologies to collect information about your visits to this and other websites in order to provide relevant advertisements. This is standard practice across the web and is how free websites are funded.
We do not sell your personal data to advertisers. Advertisers receive aggregated audience data not individual profiles from us.
Luna is our AI sleep assistant powered by the Anthropic Claude API. When you interact with Luna the following applies.
Important. SleepQuify and Luna do not provide medical advice. If you have concerns about your sleep health please consult a qualified healthcare professional.
SleepQuify uses the following third party services, each with their own privacy policies.
Powers the Luna AI assistant. Privacy policy at anthropic.com/privacy.

If you are located in the European Union or European Economic Area you have the following rights regarding your personal data.
Because SleepQuify does not collect or store personal data beyond standard server logs and advertising cookies, most of these rights are exercised through your browser settings or through the third party services listed above. To exercise any right or ask a question contact us at hello@sleepquify.com.
SleepQuify is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information please contact us and we will delete it.
We may update this privacy policy from time to time. When we do we will update the date at the top of this page. Continued use of SleepQuify after any changes constitutes acceptance of the updated policy.
