Privacy Policy

Kasane / Last updated: September 23, 2026

日本語版

Katsumi Sakurai ("the developer") provides this policy for the iOS app "Kasane" ("the app").

1. Information we do not collect

The app requires no account and the developer operates no server. The developer never receives any information about you. Google may, however, access information in order to serve advertisements (see "3. Advertising" below).

The app does not access or collect your name, email address, phone number, contacts, location, camera, microphone, health data, photos or calendar.

2. What is stored on your device

The app stores only the highest number of orders you have completed, using the standard iOS storage (UserDefaults).

Behaviour
StoredA single number: your best order count
LocationOn your device only. Not synced to iCloud
TransmissionNone. It never leaves your device
DeletionRemoved together with the app

3. Advertising

The app displays a banner advertisement at the top of the screen, served by Google AdMob. To deliver these ads, Google may access and use information such as the advertising identifier (IDFA).

Handling
Received by the developerNothing. Google never passes personally identifying information to the developer
Collected byGoogle LLC (AdMob)
PurposeServing advertisements and measuring their performance

See Google's policies and terms for how Google handles this information.

4. App Tracking Transparency

On iOS 14.5 and later, the app asks on first launch whether it may use the advertising identifier to show ads relevant to you. Declining does not change the game in any way - you simply see ads that are not personalised.

You can change your answer at any time in Settings → Privacy & Security → Tracking.

5. Network access

The app connects to the network only to fetch advertisements. Nothing about your play or your records is transmitted.

6. In-app purchases

There are none. No money changes hands inside the app. The "lightning" used to place pieces refills with time and cannot be purchased.

7. Children

The app may be used at any age. The developer collects no personal information. Advertising content is filtered for age-appropriateness through Google AdMob's settings.

8. Changes to this policy

If this policy changes, the updated version will be published here with a new "Last updated" date.
