Privacy policy

Effective 4 November 2026

Color King (“we”, “us”) makes the mobile game Color King: Rangoli Capture Puzzle and this website. This policy explains what data the game and the website collect, why, who we share it with and the choices you have. We do not sell your personal data.

The short version

  • You never create an account. The game signs you in anonymously so friend challenges work.
  • The only name we store is the display name you choose for challenges and leaderboards.
  • The campaign, Daily Rangoli and arcade mode play offline; only challenges and leaderboards use the internet.
  • Ads are served by Google AdMob, and purchases are handled by Google Play or the Apple App Store. We never see your card details.
  • Color King is meant for players aged 13 and over.

1. Anonymous sign-in (Firebase Authentication)

When you first open the game, Google Firebase Authentication creates an anonymous account for your install: a random identifier (a “user ID”) with no email, phone number or password. It lets us tell your challenges and scores apart from everyone else’s. If you uninstall the game or clear its data, a new identifier is created the next time you play and the old one can no longer be used.

2. Friend challenges and leaderboards (Cloud Firestore)

When you use online features, we store the following in Google Cloud Firestore (hosted in India):

  • Profile: your display name (1–20 characters), the avatar you pick and when you created the profile.
  • Challenges you send: your display name, the map and random seed, a replay of your steering (each change of direction and its timing during the 90-second match), your final score and when the challenge was created and expires (7 days later).
  • Challenges you play: your display name, your steering replay, your score and when you played. These are visible to the challenge creator and to anyone who opens the challenge link, including the leaderboard on colorking-game.vercel.app/c/… pages.
  • Daily arcade leaderboard: your display name, avatar and best score for the day.

Replays contain only steering directions and timings, never your location, contacts or anything else on your device. Our server re-plays them to check that scores are genuine. We keep challenge and leaderboard data only as long as it is useful for showing results to you and your friends, and you can ask us to delete yours at any time (see section 9).

3. Ads (Google AdMob)

The game shows rewarded ads that you choose to watch and, from level 8 onward, occasional full-screen ads. Ads are provided by Google AdMob, which may collect your device’s advertising ID, IP address and information about ad interactions to show, measure and limit ads and to prevent fraud. Where required (for example in the EEA and UK) you will be asked for consent before personalised ads are shown. On Android you can reset your advertising ID or opt out of personalised ads in Settings → Google → Ads (or Privacy → Ads). On iPhone the game does not ask to track you, so ads do not use your advertising identifier. See how Google uses information from sites or apps that use its services.

4. In-app purchases (Google Play and the App Store)

Coin packs, the starter pack and “Remove ads” are bought through Google Play Billing on Android and through Apple’s App Store on iPhone. The store processes your payment; we receive only a confirmation of what you bought (product, order or transaction ID and purchase token) so we can deliver it and restore it later. We never receive your card or UPI details. Payments are covered by the Google Payments Privacy Notice and Apple’s Privacy Policy.

5. Analytics

To understand which levels are too hard and whether the game works well, the game records gameplay events such as level started, completed or failed (with stars, loops and time), hints used, ads shown, purchases, challenges sent, opened and played, and share-card use. Events carry a random install ID created by the game, a session ID, the app version and platform and, once you are signed in, your anonymous user ID. They are sent only to our own server at colorking-game.vercel.app, which checks them and records them in its logs; they are not shared with advertisers. We use this data only in aggregate to improve the game, and keep raw events for up to 14 months.

6. This website

colorking-game.vercel.app is hosted on Vercel. Like most websites, its servers log technical data (IP address, browser type, the page requested and the time) for security and to keep the site running; these logs are kept for a short period. The website does not use advertising cookies.

7. Who we share data with

We share data only with service providers that run parts of the game for us — Google (Firebase Authentication, Cloud Firestore, AdMob and Google Play), Apple (App Store purchases) and Vercel (hosting for this website and our analytics endpoint) — under their own privacy and security commitments, and when the law requires it. Your display name, scores and challenge replays are visible to other players as described above.

8. Children

Color King is intended for players aged 13 and over and is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child under 13 has used online features, contact us and we will delete the related data.

9. Your choices and rights

  • You can play the campaign, Daily Rangoli and arcade offline without sending challenges.
  • You can change your display name at any time in the game.
  • You can ask us to access, correct or delete the data linked to your anonymous ID. Include the player ID shown in the game’s settings so we can find it.
  • Depending on where you live (for example under India’s Digital Personal Data Protection Act 2023 or the EU/UK GDPR), you may have further rights, including withdrawing consent and complaining to a data protection authority.

10. Security

Data is sent over encrypted connections and stored with Google Cloud. Security rules ensure each player can only write their own profile, challenges and scores.

11. Changes

If we change this policy we will update the date above, and tell you in the game if the change is significant.
