CluPix Privacy Policy
Notice (posted November 8, 2026): this policy takes effect on November 15, 2026. The web version will use Google Analytics for visit statistics. In the European Economic Area, the UK and Switzerland it is used only if you agree; elsewhere it is used without asking and you can turn it off at any time. It is not used in the app (sections 1, 2, 3, 4 and 7).
KenStudio (“we”) processes personal information of people who use the CluPix app and web version (clupix.vercel.app; together the “Service”) as described below.
1. Information we process
The Service has no sign-up. When you first open the app, or press “Start” on the web, an anonymous account is created automatically, without your name, email or phone number. App and web accounts are separate, and each browser gets its own web account.
| Created automatically | Anonymous account ID, member code, nickname (initially “user” + 6 digits; you can change it) |
|---|---|
| Settings | Display language |
| Game records | Quizzes played, per-question and final scores, rankings, start/finish times, per-category totals, quizzes you created |
| Usage records | Times and results (correct or not) of app/web launches, games started/finished and answers |
| Error reports | If you report a problem with a quiz question: the question, the reason, your optional comment, the time and the outcome |
| Sign-up source | One item about how you first came to the Service: the name attached to a promotion link, whether you came through an invite link, the domain of the site you came from (web), or the install source reported by Google Play (app). Saved once, when your account is first created |
| Visit statistics (web) | A random identifier in the Google Analytics cookie, the address of the screens you view (invite codes are not sent), the domain of the previous page, visit times, device and browser type, approximate region. Not linked to your member code or nickname |
| Collected automatically | IP address, access time, request logs (server logs) |
We do not process your name, email, phone number, contacts, precise location or advertising ID.
Sound and vibration settings, cached images and sign-in tokens stay on your device (on the web, in your browser storage) and are not sent to us. The web version remembers how you first came in, in browser storage, sends it as the “sign-up source” above when your account is created, and then deletes it.
The web version remembers the display language you choose in a cookie (clupix_lang, 1 year). It is sent with page requests only to pick the screen language and is not stored by us. We use no advertising cookies. If you clear your browser’s site data you can no longer get back into your web account, so delete the account first or note your member code if needed.
The web version uses Google Analytics cookies (_ga and _ga_*, 180 days) for visit statistics. If you connect from the European Economic Area, the UK or Switzerland, we ask on your first visit and use them only if you agree. Elsewhere they are used without asking. The app does not use them.
You can turn visit statistics off at any time. Turning off Settings → Visit statistics cookies on the web, or using the button below, stops sending data and deletes the cookies. The Service works the same with them off. You can also use Google’s opt-out add-on or block cookies in your browser, but blocking this site’s cookies in your browser may stop your web account from working.
2. Purposes
- Serving and scoring quizzes, ranking, and letting you challenge quizzes created by other players
- Checking nickname duplicates and resuming unfinished quizzes
- Preventing abuse (time-limit checks, suspensions), fixing errors and improving the Service
- Reviewing and fixing quiz data errors you report, and showing you the outcome
- Usage statistics (launches, games, accuracy over time), viewed only as totals that do not identify anyone
- Measuring how well our promotion works (sign-ups and play by sign-up source), viewed only as totals per source
- Web visit statistics (which screens are viewed and where visitors come from), viewed only as totals
3. Retention
- Account information (including sign-up source) and game records: until you delete your account.
- When you delete your account, everything that identifies you (nickname, member code, account) is deleted without delay. Scores and rankings of games you finished are kept in anonymized form so that the rankings of other players who played the same quiz do not change.
- Usage records: when you delete your account, the link to you is removed and they remain only as anonymous statistics.
- Error reports: kept as the basis for fixing quiz data; when you delete your account, the link to you is removed and they remain anonymous. Please do not include personal information in comments.
- Visit statistics: the cookies last 180 days and user-level data in Google Analytics is deleted automatically after 2 months. If you turn them off, the cookies are deleted right away.
- Server logs are deleted automatically according to the retention policies of the providers in section 4.
4. Service providers and international transfer
We use the following service providers. Your information is processed on servers outside Korea whenever you use the Service.
| Provider | Server location | Information | Purpose | Retention |
|---|---|---|---|---|
| Supabase, Inc. (USA) | Singapore | All items in section 1 | Database, authentication, file storage | Until account deletion or end of contract |
| Vercel Inc. (USA) | Singapore and others | IP address, request logs | Hosting | Per provider policy |
| Google LLC (USA) | USA and others | Visit statistics in section 1 (the IP address is used only to work out the region and is not stored) | Web visit statistics | 2 months |
Provider policies: supabase.com/privacy, vercel.com/legal/privacy-policy, policies.google.com/privacy
5. Deletion
Deleted data is removed from our database immediately and cannot be recovered. Anonymized scores cannot identify you.
6. Your rights
- Access: see your nickname, quizzes played and scores in the app or on the web.
- Correction: change your nickname in Settings.
- Deletion: Settings → Delete account (app or web). If you cannot use the app or that browser, email us with the member code shown in Settings. See Account deletion.
- For other requests, contact us below.
7. Children
- The Service has no age limit and can be used by children.
- There is no sign-up or log-in, and we do not collect information that directly identifies a child, such as a name, date of birth, phone number, email, address, photo, precise location or advertising ID. The Service shows no ads, and we never use a child's information for targeted advertising or sell it. The companies in section 4 only provide services on our behalf.
- The Service only processes the information listed in section 1 (an anonymous account ID, nickname, game records, usage records and visit statistics) and uses it only to run the game, show rankings and produce usage statistics.
- The web version's visit statistics contain nothing that directly identifies a child. A parent or guardian can turn them off in Settings → Visit statistics cookies on the web, or in the ways described in section 1.
- Nicknames are shown to other players on rankings and challenge lists. Please do not use a real name, school or contact details as a nickname. Nicknames with swear words, slurs or hateful expressions cannot be used, and we may replace an inappropriate nickname with an automatic one.
- Please do not write personal information in error reports either. If we find a child's personal information there, we delete it.
- A parent or guardian can ask to see, correct or delete a child's information, or to stop processing it. You can delete the account right away in Settings → Delete account, or email us at the address in section 9 with the member code shown in Settings, and we will handle it without delay.
8. Security
- All traffic is encrypted (HTTPS).
- Database administrator credentials are kept on the server only, never in the app or web pages.
- The operator console requires a separate operator account.

10. Changes
We will announce changes in the app, on the web or on this page at least 7 days before they take effect.
