This Privacy Policy explains how Sum61 collects, uses, shares, and protects information when you use the Sum61 website and application at https://sum61.com.
Information We Collect
Account Information
When you create an account, we may collect:
- Email address
- Display name or username
- Legal acceptance records, including the age/guardian statement selected at signup
Game and Profile Information
We store gameplay information needed to operate the Service, including game history, ratings, leaderboards, puzzle progress, profile customizations, reports, blocks, friends, invitations, and store purchases.
Usage and Device Information
We and our service providers may receive technical information such as IP address, browser type, device information, pages visited, time spent, approximate location derived from IP address, and diagnostics needed for security, fraud prevention, analytics, and service reliability.
Cookies, Local Storage, and Similar Technologies
We use essential cookies or local storage to keep the Service working, including login, settings, gameplay state, cookie choices, and fraud prevention. We may use optional technologies for analytics, advertising, measurement, and improving the Service when permitted by your choices and applicable law.
Advertising and Google AdSense
Sum61 may show ads through Google AdSense or related Google advertising services. Google and its partners may use cookies, local storage, web beacons, IP addresses, device information, and similar technologies to serve ads, measure performance, prevent fraud and abuse, and, where permitted, personalize ads.
If you choose personalized ads, ads may be based on information such as your activity on Sum61, your activity on other sites or apps, and demographic or interest data associated with your browser or device. If you reject optional tracking, close the consent notice, or have not made a choice, we may still show limited or contextual ads where available. Limited or contextual ads are not based on your past behavior for ad personalization, but Google may still process data such as IP address and may use technologies needed for basic ad serving, security, fraud prevention, and reporting.
Learn more about how Google uses information from sites and apps that use Google services at https://policies.google.com/technologies/partner-sites. You can manage Google ad personalization at https://myadcenter.google.com/.
Your Privacy Choices
You can accept optional advertising and measurement technologies or reject optional tracking from the cookie notice. Rejecting optional tracking does not necessarily remove all ads; it means we should not request personalized ads based on optional tracking. In regions where a certified consent management platform is required for personalized ads, we will use a Google-certified consent flow before requesting personalized ads.
Children and Teens
Sum61 is intended for a general audience, but children may use the Service with the involvement and permission of a parent, guardian, or school where required. Users creating an account must confirm whether they are 13 or older, or whether they are under 13 and using the Service with parent or guardian involvement and permission.
We do not knowingly request personalized ads for users we know are under 13. If a parent or guardian believes a child has provided personal information without appropriate permission, contact us and we will take reasonable steps to delete or correct the information.
How We Use Information
- To provide, maintain, secure, and improve the Service
- To manage accounts, profiles, leaderboards, friends, reports, and gameplay
- To process payments, subscriptions, coins, and virtual items
- To send service-related emails such as verification or login messages
- To detect abuse, cheating, spam, fraud, and security issues
- To show ads and measure ad performance where permitted

How We Share Information
We do not sell your personal information. We may share information with:
- Hosting, database, authentication, and infrastructure providers such as Supabase and Vercel
- Payment processors such as Stripe
- Advertising partners such as Google AdSense
- Analytics, security, and fraud-prevention providers
- Legal authorities when required by law or needed to protect rights and safety
User-Generated Content
Display names, public profile details, leaderboard entries, and other gameplay-related information may be visible to other users. Please do not include sensitive personal information in public-facing fields.
Retention
We keep information only as long as reasonably needed to provide the Service, comply with legal obligations, resolve disputes, enforce agreements, prevent abuse, and keep accounting or transaction records.
Your Rights
Depending on your location, including Canada, the European Economic Area, the United Kingdom, Switzerland, and California, you may have rights to access, correct, delete, export, restrict, or object to certain processing of your personal information, and to withdraw consent where processing is based on consent.
International Transfers
Your information may be processed in countries other than where you live, including jurisdictions with different data protection laws.
Security
We use reasonable safeguards to protect information, but no method of transmission or storage is completely secure.
Asset Credits
Third-party asset credits and license notices are listed on the Asset Credits page.
