Privacy Policy
Chromibop · iOS · Android · Effective: 2026-10-07
Summary
Chromibop does not ask for your email, name or phone number. To take part in the rankings you only choose a nickname and a country.
Your nickname, country and stage records are kept on our server for the rankings, and your nickname, country and scores are shown to other players in the rankings. All other progress and settings are stored on your device.
Ads are shown through Google AdMob, and ad-related information is processed by Google.
You can delete your account inside the app at any time (Settings → Delete account).
This policy applies only to the iOS · Android app Chromibop. Other Ggeomddakji apps follow their own policies.
1. Information we collect and store
Kept on our server for the rankings
| Item | What it is |
|---|---|
| Player ID | A random value the app creates on first launch. It does not identify you |
| Nickname | The name you typed. Shown in the rankings |
| Country | The country you chose. Shown in the rankings |
| Stage records | Stage number, clear time, score, stars, cleared or failed |
| App information | Platform (iOS · Android), app version |
| Times | When you registered, changed your nickname or country, and were last seen |
| Sign-in data | A hash of a secret stored on your device. The secret itself is never stored on the server |
| Fair-play checks | The reason, when a record arrives that no person could achieve |
To stop excessive requests, the server briefly uses your IP address. IP addresses are not stored in the database.
Kept only on your device
- Progress — stages cleared and stars, hearts, achievements, looks, tips already seen
- Settings — music, sound effects, vibration, screen shake, reduce motion
- Save-file check — a device identifier is used to check that the save file has not been altered. It is never sent anywhere.
- Heart notifications — the "hearts are full" notification is scheduled on your device and does not go through any server.
Ad-related information (Google)
The app offers rewarded ads (get hearts, continue, help items) through Google AdMob. To show ads and prevent abuse, Google may collect and process:
- Advertising ID (on iOS only if you allow tracking)
- Device type, OS version, language setting
- Approximate location (city level) inferred from your IP address
- Ads you viewed or tapped
On iOS a prompt asks whether you allow tracking. The game plays exactly the same if you don't. The developer only receives aggregate reports (impressions, revenue, etc.).

3. Why we use it
- To show world and country rankings
- To filter out unfair records and keep the rankings fair
- To store your progress on your device
- To show ads and grant rewards
- To send heart notifications
- To answer your inquiries
We do not sell any information, and we do no profiling other than for ads.
4. Third parties
| Who | What | Why |
|---|---|---|
| Google (AdMob · UMP) | Ad-related information | Showing ads, preventing abuse, managing consent |
| Cloudflare | Ranking information (the server data in section 1) | Running the ranking server and database (storing and processing it on our behalf) |
No information goes anywhere else. We use no analytics or tracking tools.
5. Retention and deletion
Ranking information on the server is kept until you delete your account.
- In the app — Settings → Delete account. Your nickname, country, stage records and rankings are deleted from the server immediately and cannot be restored. They also disappear from disaster-recovery backups within 30 days at most.
- By email — if you have already removed the app, send us your nickname and country at the address below and we will delete them.
Progress on your device stays when you delete your account. It is removed together with the app.
Ad-related information is retained under Google's policies.
6. Your rights
- Access and correction — change your nickname and country in the profile in the app (changes are limited to certain intervals).
- Deletion — Settings → Delete account
- Withdraw ad consent — Settings → Ad privacy (offered where consent is required)

Residents of the EEA and UK have the rights of access, rectification, erasure, portability, restriction and objection under the GDPR; California residents have rights under the CCPA/CPRA. Ad-related requests may also need to be sent to Google.
7. Children's privacy
This app is intended for users aged 13 and over and is not designed for children. We do not knowingly collect personal information from children under 14 (under 16 in the EEA, under 13 in the US). If we learn that such information has been collected, we delete it immediately. Nicknames are checked to filter out inappropriate words.
8. Security
Communication between the app and the server is encrypted with HTTPS. The server keeps only a hash of the sign-in secret, never the secret itself. The save files on your device sit in the app's own storage, which other apps cannot read.
9. Changes to this policy
If this policy changes, we update the effective date and post it on this page. Important changes are also announced in the app.
