Privacy Policy

When you play

Your best score, sound setting and language choice are saved in your browser for your next visit. They remain until you or your browser clears this site’s data.

When you visit, Google processes your IP address and connection information to deliver the site and prevent abuse. Your approximate country or region is also used to select the initial language; precise location is not requested.

When you sign in and join the ranking

You can play without signing in. Joining the ranking requires Google sign-in. We receive your account identifier, email address, name and profile photo for sign-in and account management. Authorized staff can access this information, but it is not published on the ranking.

The ranking publishes your game nickname and results (score, stage and maximum combo). We link them to your game account and send gameplay information, including your input history, to the server to verify scores and prevent cheating. Input history is not saved in the ranking database.

When you share a video or image

Replay videos and score images are created on your device and are not uploaded to our server. The game does not record your camera or microphone. Sharing sends the file, results and game URL to the destination you choose, whose privacy policy applies. Nothing is posted automatically.

How long information is kept

• Temporary replay data is cleared when you start a new game, reload or close the page. Downloaded files and external posts remain until you delete them separately.

Google keeps hosting IP records for a few months and authentication IP records for a few weeks. After an account deletion request, authentication data is removed from live and backup systems within 180 days. Other provider records follow the retention terms linked below.

Deleting information and making requests

Use “Delete game account” on the ranking screen to delete your game profile and ranking records and request deletion of your sign-in account. Your Google account itself is not deleted. To remove data saved in your browser, clear this site’s data in your browser settings.

For disclosure of your personal data or third-party disclosure records, correction, deletion, restriction of use or cessation of third-party provision, use the contact form below. After verifying your identity as needed, we respond in accordance with applicable law. If a fee is necessary, we explain the amount before proceeding.

Services used and security

We use Google Firebase for hosting, sign-in (Firebase Authentication) and ranking storage, and App Check with reCAPTCHA Enterprise to prevent abuse. Google processes identifiers, verification data, IP addresses and browser information. reCAPTCHA may use cookies. Authentication data is processed in the United States; other data may also be processed outside your country by Google and its service providers.

We protect information using encrypted communication, restricted administrative access and server-side access checks. Except for publication or sharing you choose, processing by service providers for these purposes, or cases permitted by law, we do not provide personal data to third parties without your consent.

Payments and advertising are not currently enabled. We do not use Google Analytics or another analytics SDK in the game.
