Privacy Policy

Network connection display and full network access

Artesnaut uses the network to obtain the time in the application. It also uses third-party services to collect app progress and crash information in order to improve the stability of the Service. On the iOS and Android versions, we use both Firebase (including Crashlytics) provided by Google LLC and Sentry provided by Functional Software, Inc. On the Windows (Steam) version, Firebase Crashlytics is not used, and crash reports and diagnostic information are collected via Sentry only.

For more information, please see Firebase's Privacy and Security and Sentry's Privacy Policy.

Automatic data collection by advertisers

Advertisements are displayed only on the iOS and Android versions. The Windows (Steam) version does not display advertisements and does not use AdMob.

On the iOS and Android versions, we make use of AdMob (Google, Inc.). AdMob automatically collects usage data about the application. The data collected, purpose, and policy for sharing with third parties is specified within the Privacy & Terms at the following link:

External Account Login

When you log in using an external service such as Google Sign-In or Apple Sign-In, we access the following information:

• Email address
• Unique account identifier

This data is used solely for the purpose of authenticating your identity and creating/managing your account within the app via Firebase Authentication.

We do not use this data for any other purpose, including advertising, analytics, or AI/ML model training. We do not share this data with third parties except as required by Firebase Authentication to maintain your account. This data is not stored on our servers beyond what Firebase Authentication retains for account management.

For more information about Firebase's data handling, please see: firebase.google.com/support/privacy

On the Windows (Steam) version, a unique user ID is automatically generated based on your Steam account identifier (SteamID). We do not access your Steam password or your Steam profile information beyond the identifier necessary to create and manage your account. On the Steam version you can choose between the Japan server, the overseas server, and the Simplified Chinese server; if you select the Simplified Chinese server, authentication is handled via Supabase (hosted on Alibaba Cloud) instead of Firebase Authentication (see "Data Storage Location" below).

Data Storage Location

The location where your account and game data are stored depends on the platform you use and the server you select. On the iOS and Android (mobile) versions, as well as on the Japan and overseas servers of the Windows (Steam) version, your data is stored on Firebase / Google Cloud infrastructure. On the Simplified Chinese server of the Windows (Steam) version, your data is stored on servers operated on Alibaba Cloud (located in the Hong Kong region). By using any of these servers, you consent to your data being stored and processed on the infrastructure and at the location associated with the server you select, including any cross-border transfer of data that this may involve.

Builds you post to the Build Encyclopedia are an exception to the above: whether public or private, they are replicated across all servers regardless of the server you select, and are therefore stored on both Firebase / Google Cloud and Alibaba Cloud infrastructure. Non-public builds remain viewable only by you.

Automatic Translation of Posted Content

When you post or update content in the Build Encyclopedia, the text you enter (such as the build name and description) is sent to Google's Gemini API to be automatically translated into the languages supported by the Service. We use the Gemini API under a paid plan, and the text sent is not used to train Google's models. For more information about how this data is handled, please see the Gemini API Additional Terms of Service and Google's Privacy Policy.

Communications with Us

We can be contacted through e-mail. We will carefully protect your privacy and will never show or provide the contents of your communication with Us to third parties. We will never force you to enter personally identifying information or automatically collect or transmit such data.

Restriction on Releasing Private Information to Third Parties

Artesnaut will carefully manage any personal information obtained from you. Such information will not be released to third parties except in the following cases:

• We are required to release the information by law

Compliance with the Law/Standards and Revisions

Artesnaut will comply with Japanese law and standard practice with regard to your personal information while making appropriate revisions to improve this policy.
