Privacy PolicyInkroach（《落墨成勢》）

Last updated: 5 November 2026　·　Version 1.5

This Privacy Policy explains how FireCat Studio (“we”, “us”) handles information in connection with the mobile game Inkroach (the “Game”) on Google Play and the App Store.

Summary

  • The Game has no user accounts, and we do not create profiles of players.
  • Match history, settings and collection progress are stored only on your device.
  • During online matches, limited connection information passes through our matchmaking server and is deleted automatically within ten minutes.
  • The Game displays advertising provided by Google AdMob, which may collect device identifiers and related data (see Section 2.3).
  • Payments for “Remove ads” are processed by your platform’s store; we do not receive your payment details.

This summary is provided for convenience only; the full policy below prevails.

1. Who we are

FireCat Studio is responsible for the processing described in this policy. Contact: firecat870808@gmail.com

2. Information we process

2.1　Information stored on your device

The following information is stored locally on your device and is not transmitted to us:

This information is deleted when you uninstall the Game, except for images already saved to your photo library.

2.2　Online matches

This section applies only when you use online multiplayer.

(a) Information shown to your opponent. Your display name, selected avatar and any stickers you send during a match are shown to your opponent. Avatars and stickers are images built into the Game. We recommend that you do not use your real name as your display name.

(b) Matchmaking server. To connect two devices, the room code, the network information required to establish the connection (including IP addresses), and your display name and avatar are stored temporarily on our matchmaking server, which we operate on Cloudflare’s infrastructure. This information is deleted automatically ten minutes after the room is created and is not used for any other purpose. Once connected, match data is exchanged directly between the two devices.

(c) Connection services. To determine connection addresses, the Game uses STUN services provided by Cloudflare and Google, which receive your IP address.

(d) Direct connection and abuse prevention. Because match data is exchanged directly between the two devices, the other player’s device receives your IP address during an online match. To prevent the guessing of pairing codes, if a device repeatedly enters an incorrect pairing code, the matchmaking server keeps a one-way hash of its IP address (not the address itself) together with the number of attempts, and temporarily refuses further attempts from it. This record is deleted automatically within twenty minutes.

2.3　Advertising

The Game displays advertising through Google AdMob. Google may collect and use information such as your device’s advertising identifier and other device identifiers, your IP address and the approximate location derived from it, device information, ad interaction data, and diagnostic information (such as crash and performance data), to serve, personalise and measure advertising and to prevent fraud. For details, see How Google uses information from sites or apps that use its services. Advertising does not affect gameplay or match outcomes.

2.4　In-app purchase

The Game offers a one-time purchase, “Remove ads”. Payment is processed by your platform’s store; we do not receive your name or payment details, only confirmation of whether your store account owns the item. You may restore the purchase via Settings → Restore purchases. If a purchase is refunded, its effect will be withdrawn. Refunds and payment disputes are handled by the respective store under its own terms.

2.5　Update check

The Game checks version information through GitHub. GitHub, Inc. receives your IP address and other connection information as a result; we do not obtain your IP address through this check.

2.6　Information we do not collect

We do not collect your name, email address, telephone number, contacts or precise location. We do not use analytics or tracking tools other than those required for the advertising described in Section 2.3. We do not sell personal information.
