Tilefit Privacy Policy
Last updated: 15 September 2026
Tilefit collects no personal information, stores nothing on your device, and makes no network requests of its own.
Information we collect
None. The app does not obtain your name, email address, phone number, location, contacts, photos, or any device identifier. Inside the app there is no analytics and no advertising. (The handling of this website itself is described below.)
What the app stores
Nothing. The board you are working on and the puzzle you have reached are held in memory only while the app is running. When you quit the app the progress is lost, and the next launch starts again from the first puzzle.
The app implements no mechanism to write settings, records, or history to device storage or to iCloud.
Network use
The app itself never contacts any server. The puzzle screen runs entirely from files bundled inside the app. There is no remotely loaded code, no advertising, no analytics, and no social integration.
The “ⓘ” button at the bottom of the screen reveals links to this privacy policy and to the support page. Only when you tap one of those links does Safari open this website. The app never initiates a connection on its own.
About this website (separate from the app)
This site, www.fujikawa.com, uses Google Tag Manager and Google Analytics for ordinary traffic measurement, recording things such as which pages were viewed and an approximate region.
That belongs to the website, not to the app. Nothing of the sort runs while you play. You can disable it through your browser settings or tracking protection.
Sharing with third parties
None.
What Apple passes to the developer
Only if you have turned on “Share with App Developers” in iOS Settings (Privacy & Security → Analytics & Improvements) does Apple aggregate crash logs together with your device model and OS version and make them available to the developer. If it is off, nothing is sent.
This is Apple's own mechanism, not something the app collects, and it carries no personally identifying information such as a name or email address.
The app is currently distributed for testing through Apple's TestFlight. Feedback you submit and crash logs recorded during the test may be provided to the developer through Apple. Testers who join via the public link are anonymous to the developer: no name or email address is passed on.
Deleting your data
The app holds no data to delete. Removing the app from your device leaves nothing behind.
Use by children
Because the app collects no personal information, it is safe for users of any age.
Changes to this policy
If the content changes, this page will be updated and the date above revised.
