Privacy Policy

How Tentosen and this information site handle data.

Effective: 2026-10-07 · Operator: jelkawasaki

Public apps

The Japanese iPhone and iPad app is available on the App Store, and the Japanese Android app is available on Google Play. Public apps use Google AdMob and offer a one-time ad-removal purchase through their respective stores. English language support is planned for app version 1.3.0. Store availability will begin after review and release; timing may differ by store.

This policy covers the Tentosen apps and this information site.

1. Game records and settings

The apps do not require an account. Puzzle progress, completed results, move history, created puzzles and settings are generally stored on your device. The developer does not receive them through automatic game uploads. If you export a backup, the chosen storage provider's policies also apply.

The app language choice is a functional preference stored on your device so the app can remember Japanese, English or automatic selection. It is separate from analytics consent and is not used to identify or track you. Changing language does not rewrite your saved puzzle records.

2. Ads

Public apps are configured to use Google AdMob interstitial ads, subject to frequency limits. The test app uses Google's official test ads. The Google Mobile Ads SDK may process IP address, approximate location, device or app identifiers, ad views and interactions, and diagnostic or performance information for ad delivery, fraud prevention, diagnostics and measurement. The exact processing depends on the SDK and settings.

The iPhone and iPad app does not request ATT permission and does not use IDFA. This does not mean every form of service processing is disabled. See Google's Privacy Policy and Android SDK data disclosure.

3. Consent and purchases

The apps use Google's User Messaging Platform where required to present privacy choices. Available choices can be reviewed from Settings → Ad Privacy Settings. The apps offer a one-time ad-removal purchase through Apple or Google Play. The store processes payment and shows the price. The developer does not receive your card or bank details. Store purchase rights are separate and are not included in the game backup.

4. This website and analytics choices

On the public website, Cloudflare Web Analytics counts visits, page views, referral sources and performance. It does not use cookies or persistent browser identifiers. This processing is separate from Google Analytics consent. See Cloudflare Web Analytics and its privacy policy.

If you allow it, this website uses Google Analytics 4 to measure visits, pages, referrals, approximate region, device and browser details, scrolling and outbound-link clicks. It does not intentionally send your name or email as analytics data. Until permission is given, the analytics script is not loaded and analytics information is not sent to Google. Allow or decline can be changed using the Google Analytics settings control at the bottom of each page. Declining removes this site's Google Analytics cookies; already aggregated reports are not deleted. You can use the site and demo either way. The language preference is stored separately as a functional setting.

The site has no ads, external fonts or contact form. Netlify may process access information such as IP addresses to deliver and secure the site. See Netlify's Privacy Policy. If you contact the operator, your reply address and message are used to respond. Avoid sending unnecessary personal or confidential information.

5. Web demo and sharing

Demo progress exists only in the current page memory. The demo does not save it to cookies or browser storage and does not send puzzle moves or results to the operator. Reloading or leaving the page clears progress. App images and videos are created on the device; copying text writes to the clipboard only when you choose to do so. Destination apps and storage providers apply their own policies.

6. Deleting data

Delete app data in the app's Records screen or through your device settings. Exported files and cloud or OS backups must be deleted separately from their storage location. Deleting game records does not delete Apple or Google Play purchase history or request a refund. Apple and Google manage information held by their services under their own procedures.

7. Updates and contact

This policy may be updated when app features or data practices change.
