Privacy Policy

Effective: 2026-11-02 · Version 1

This policy explains how the mobile game Scrap Derby (the "Service"), operated by ECSOFT, handles your information.

There is no sign-up. We do not collect names, email addresses, phone numbers, addresses or dates of birth.
We do not access location, contacts, photos, microphone or camera.
Rewarded ads appear only when you tap the watch-ad button in the pit box or roll-again screens; after your first match the app preloads ads, and the ad provider (Google AdMob) then processes advertising identifiers and related data (section 4). No ads appear while you are driving.
We do not sell your information or share it with third parties for marketing.
The information below is sent to our servers only after you agree to the terms.

1. Information we collect

Type	Items	When
Device identifier	A per-device value (Android: derived from the app-specific ANDROID_ID; iOS: a value generated by the app and kept in the keychain)	After agreeing, when the app talks to the server
Device info	Model, platform, OS version, app version, install source (store or not), language	When the app talks to the server
Your input	Nickname (2–10 characters)	When you create or change it
Game records	Score, place and the date of the record (coins, garage and settings stay on your device)	When a match ends
Online matches (up to 10)	Nickname, paint and decal, room info, match data (car position, speed, damage, place), IP address	While you host or join a match (relayed to players in the same room)
Ads (processed by Google AdMob)	Advertising ID (Android ad ID / iOS IDFA if allowed), IP address, device and app info, ad impressions	When a pit box or roll-again ad is loaded or shown (it may load before you choose)
Crash reports	Error details (stack trace), app version, device maker and model, OS version, memory, time — no device identifier or nickname	After agreeing, when the app crashes

Nicknames and records are public in rankings, and visible to players in the same online room. Do not put real names or contact details in your nickname.

2. Purposes

Registering and showing global rankings, marking "my record"
Finding and connecting online match rooms, relaying match data
Providing rewarded ads and preventing ad fraud
Restoring your nickname after reinstalling
Update notices, fixing crashes and improving the Service
Handling policy violations such as offensive nicknames

3. Retention

Device identifiers, nicknames and records are kept while the Service runs and deleted when it ends or when you ask. Crash reports are kept up to 1 year. Online match data is only relayed, not stored; connection logs (IP, time) may remain in server logs for troubleshooting.

4. Processors and transfers abroad

Ranking, relay and crash-report servers are run by ECSOFT in Seoul, Korea; this data is not outsourced or transferred abroad. For rewarded ads, the Google Mobile Ads SDK sends the ad data in section 1 to Google LLC (USA) when ads are loaded or shown. If you don't watch ads, nothing is sent and the game is not limited. See How Google uses information from sites or apps that use its services. Personalized ads can be turned off in your device settings; in regions that require consent the app asks first, and you can change it in Settings › Ad privacy.

5. Your rights

You may ask to view, correct or delete your nickname and records at any time. You can change your nickname in Settings; for deletion, contact us (include the version and nickname shown in Settings). See Data deletion request.

6. Children

The Service does not knowingly collect personal information from children under 14.
