EchoCircle (web and Android appdev.mikaio.echocircle). Last updated: October 29, 2026.
Summary
The game never asks for an account, name, email or location. We collect the minimum needed to measure the game and show ads, which keep EchoCircle free.
What we collect
- A random identifier generated on your device, not linked to your identity.
- Gameplay events: run start and end, score, ads watched, share taps. Used to improve the game and test adjustments.
- Daily challenge runs: the sequence of taps and the score, used to verify the leaderboard and block fake scores.
- Technical data: platform, game version and approximate country (derived from your IP address, which we do not store).
High scores and settings stay on your device only.
Ads
We use Google AdMob (app) and Google AdSense / H5 Games Ads (web). Google may use device identifiers and cookies to show and measure ads, personalized or not, according to your choice in the consent message. See how Google uses data. You can change your choice at any time in your device or browser ad settings.
Legal basis (GDPR and LGPD)
Legitimate interest for gameplay statistics and fraud prevention; consent for personalized ads.
Retention
Gameplay events are kept for up to 13 months. Daily challenge runs, for up to 90 days.
Children
EchoCircle is not directed at children under 13.
Your rights
You can request access to or deletion of the data linked to your identifier. For that, or any question, write to [email protected].
