MIHANYA
Small games, strange ideas, and things we wanted to exist. MIHANYA is an independent label creating small games and apps.
MISSION
Make something memorable.
Even if it is not a large project, we want to create something that stays with the people who play it.
Something that makes you smile a little, feel strangely at ease, or come back to mind later.
MIHANYA creates games and apps like that.
APPS
Gorilla Fishing Diary
A small fishing game set in Mito, where you can catch fish, walk around town, and occasionally encounter gorillas.
Fish, collect, explore - and by the end, learn a little about this town.
Android / Google Play
Starfall Mesa
A game you can simply watch, leave running in the background, and enjoy at your own pace. A game with customization features that stays close to everyday life.
It is something I had wanted to create for a long time, finally brought to life.
Android / Google Play
ABOUT MIHANYA
MIHANYA is an independent development project based in Japan.
We create games, illustrations, pixel art, apps, and whatever else we feel inspired to make at the time.
PRIVACY POLICY
MIHANYA ("we", "us", or "our") establishes the following Privacy Policy regarding the handling of user information in the apps we provide.
1. Collection of Personal Information
Our apps do not collect information that directly identifies users, such as names, email addresses, physical addresses, or location information.
However, when using the world ranking feature, we collect the three-character alphanumeric name entered by the user.
There is no standard account registration or login system used to identify individual users.
2. Transmission of User Data to External Services
To provide world ranking display and registration features, the following information is transmitted to and stored on external servers operated by the cloud service Supabase:
- The three-character alphanumeric name entered by the user
- Information identifying the fish species
- Catch size
- Anonymous authentication information used for the ranking feature
IP addresses, device information, communication logs, and similar data may also be processed by service providers such as Supabase for service operation, security, and prevention of unauthorized use.
This information is used only to provide the world ranking feature and is not used for advertising purposes. Other game progress data, such as the collection, points, bananas owned, and volume settings, is stored locally on the device.
In the WORLD feature of Starfall Mesa, preset emoji data selected by the user within the app is transmitted to an external server and temporarily stored so that it can be displayed to other users. Free-form text, names, usernames, and similar information are not collected. WORLD emoji data is automatically deleted after approximately two days.
If the user voluntarily chooses to use rewarded ads, the Google Mobile Ads SDK (AdMob) may process information such as the app name, advertising identifiers, IP address, device information, and information related to ad display and interaction for purposes including ad delivery, ad performance measurement, and fraud prevention.
Where required by region, necessary consent is obtained through the Google User Messaging Platform.
3. Sharing with Third Parties
We do not sell user information to third parties.
However, to the extent necessary to operate the world ranking feature, we entrust the processing of information to Supabase, our cloud service provider. Except where required by law, we do not otherwise provide or share this information with third parties.
In addition, to provide optional rewarded advertisements, we entrust Google, our advertising service provider, with processing the information described above. Please refer to Google's own documentation for details on how Google uses information.
4. Advertising
Our apps display rewarded advertisements provided by Google AdMob only when the user voluntarily chooses the "Watch Ad" option.
Watching ads is optional. Users who complete viewing a rewarded ad receive in-app garden points.
5. In-App Purchases
Our apps may offer optional paid features, such as support for the developer.
Payments are processed through payment systems provided by platforms such as Google Play. We do not directly collect credit card information or other payment details.
6. Changes to This Privacy Policy
We may revise this Privacy Policy in response to the addition of new app features, changes to our services, or changes to external services used by the apps.
The revised Privacy Policy becomes effective when it is published on this page.
