Daily Logic Lab provides free browser-based logic puzzles and puzzle helper tools. This policy explains what information may be collected when you use the site.
Information You Provide
No account or sign-in is required to play. Optional card tips are entered on Stripe's hosted payment page. Information posted through GitHub issues is handled by GitHub and may be public.
Local Browser Storage
The puzzle experience may store small pieces of data in your browser, such as streak status, best times, solved dates, hint counts, and recent in-browser event records. You can clear it by clearing site data in your browser settings.
Analytics
Daily Logic Lab uses Google Analytics to understand aggregate site usage, such as page views, puzzle starts, hints, checks, and general device or browser information. Google may use cookies or similar technologies for measurement.
Support measurement includes prompt views, dialog opens, selected amounts, payment-page requests, errors, redirects and wallet-address copies. These are interaction signals, not proof of payment. Events can include language, entry point, payment method, amount, network and currency; we do not add card details, email addresses, wallet addresses, transaction hashes or Checkout Session identifiers to these events.
Separately, our server confirms successful card payments with Stripe and reports a purchase to Google Analytics with the amount before fees, currency and a pseudonymous transaction reference. If available, browser analytics client and session identifiers are passed to Stripe to associate the payment with the visit; otherwise a payment-specific identifier is used without visit attribution. Repeated notifications are deduplicated. Card details, names, email addresses and raw Stripe payment identifiers are not sent in these analytics events.
Optional Tips and Payments
For card tips, our server sends the selected amount, page language and return page to Stripe to create a one-time payment page. Stripe processes the payment and any contact details entered there. We can view payment records and customer information provided to Stripe in our Stripe Dashboard; this website does not collect card numbers.
Cryptocurrency tips are sent from your wallet to the displayed public address. Blockchain transactions are public, and wallet providers have their own privacy practices. We do not request a transaction hash or verify a transfer on this site.
Third-Party Links
The site may link to external pages, such as GitHub or Google documentation. Daily Logic Lab is not responsible for the privacy practices of external websites.
Children's Privacy
Daily Logic Lab is a general-audience puzzle site and does not knowingly collect personal information from children.
