How this site handles information
Privacy Policy
Riddle Den is a static puzzle library with no account registration, newsletter, comments, contact form, or advertising. We use Google Analytics 4 to understand aggregate site use and PDF downloads.
This notice describes the site as currently configured, including Google Analytics 4. It will be updated before advertising or a contact form is enabled.
Information you provide directly
Riddle Den currently provides no form, account, upload, purchase, or subscription feature through which you can submit personal information. Downloading a puzzle PDF does not require registration.
Technical delivery data
The hosting and network providers that deliver the site may process ordinary technical information such as an IP address, browser or device details, request time, requested URL, and security logs. That processing supports delivery, reliability, access control, and abuse prevention and is governed by the relevant provider terms and policies.
Cookies and similar technologies
Riddle Den uses Google Analytics 4 to understand aggregate use of the website. Google Analytics may use cookies or similar identifiers to distinguish visits and measure activity. The hosting and security services used to deliver the site may also use essential technologies needed for reliable delivery and abuse prevention.
Advertising and analytics
Riddle Den uses Google Analytics 4 to measure page views, device category, general traffic source, and PDF-download activity. We use this information to understand which free resources are useful and to improve the website. We do not sell personal information, run advertising on the site, or use Analytics to make decisions about individuals. Google processes Analytics data under its own terms and privacy policy; you can use Google’s Analytics opt-out browser add-on if you do not want your activity measured.
Children's privacy
Some puzzles may be used by children, but the website is not designed to collect personal information from children. There are currently no submission, messaging, account, or profile features.
External links and downloads
Some factual puzzle pages link to authoritative external sources. Those sites operate under their own privacy practices. Puzzle PDFs are served as static files from this site.
Changes and privacy requests
This policy will be reviewed whenever the hosting arrangement, contact method, analytics, advertising, or visitor-facing features change. A monitored domain-based privacy contact will be added to the Contact page before messages are accepted.
