Privacy Policy

Effective: 2026.09.24 · Version 2 (rewarded ads added)

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

There is no account sign-up. We do not collect names, e-mail 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 a button on the "Get items" screen; at that time the ad provider (Google AdMob) processes information such as the advertising ID (see section 4). There are no ads during games.
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-scoped ANDROID_ID; iOS: generated by the app and kept in the Keychain)	On launch and server requests, after consent
Device info	Model, platform, OS version, app version, install source, language	On server requests
Your input	Nickname (2–10 characters)	When you create or change it
Game records	Endless Tower score, floors escaped, date (campaign records stay on the device)	When an Endless Tower run ends
Ads (processed by Google AdMob)	Advertising ID (Android advertising ID / iOS IDFA, if you allow it), IP address, device and app information, ad impressions and views	When an ad is loaded or watched on the "Get items" screen
Crash reports	Error details (stack trace), app version, device maker/model, OS version, memory size, time — no device identifier or nickname	After consent, when the app crashes

Nicknames and records are public on the leaderboard. Do not put personal information in your nickname.

2. Purposes

Registering and showing the global leaderboard and marking your own record
Providing rewarded ads and preventing ad fraud (items received from ads are stored only on your device)
Restoring your nickname after reinstalling
Update notices, crash analysis and service improvement
Handling policy violations such as inappropriate nicknames

3. Retention

Device identifiers, nicknames and records are kept while the Service runs and deleted without delay when the Service ends or you ask. The device identifier may remain on the device after uninstalling (to restore your records) and changes on factory reset. Crash reports are kept up to one year.

4. Processors and transfers

The leaderboard and crash-report servers are run by ECSOFT in Seoul, Korea; this information is not outsourced or transferred abroad.

For rewarded ads, the Google Mobile Ads SDK included in the app sends the ad information in section 1 to Google LLC (United States). When: when an ad is loaded or watched · How: network transmission · Retention: according to Google's policies · How to refuse: nothing is sent if you do not watch ads, and the game can be played without restriction. See How Google uses information from sites or apps that use its services.

You can turn off personalized ads in your device settings (Android: Settings › Google › Ads › Delete advertising ID / iOS: Settings › Privacy › Tracking). In regions that require consent, such as Europe, the app asks for consent first and you can change it under "Ad privacy settings".

5. Your rights

You may ask to access, correct or delete your nickname and records at any time. You can change your nickname in Settings; for deletion see Data deletion.

6. Children

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

Changes are announced in the app and on this page; material changes require renewed consent in the app.
