This Privacy Policy explains how we collect, use, and share information when you play the Game on mobile (iOS / Android).
1. Summary
- Core gameplay (saves, settings, local matches) stays on your device.
- Optional online matches use Firebase (Google) to host short-lived rooms. We use anonymous authentication — no name or email is required.
- We do not show ads in the Game.
- We do not currently run a separate first-party product-analytics product inside the Game.
- App stores (Apple, Google) process their own account, download, and crash data under their policies.
2. Who this applies to
This policy applies to players of Hex on iOS and Android.
If you access the Game through a third-party platform, that platform may collect and process data under its own privacy policy.
3. Information we process
3.1 Stored on your device (local)
These are needed to run the Game and are kept locally (for example under the app sandbox):
| Category | Examples |
|---|---|
| Settings | Audio, language/locale, other options you choose |
| Local play | In-progress local or AI matches, board size, and related session state |
| Online helpers | A stored anonymous Firebase session token so you can rejoin a room without a new identity mid-match |
Local save files are not uploaded to Hyakan servers as part of normal play.
3.2 Online rooms (Firebase)
If you create or join an online room, the Game talks to Google Firebase Authentication (anonymous sign-in) and Firebase Realtime Database to exchange match state. Typical data:
- An anonymous user id issued by Firebase (not your name or email)
- Room codes and match state (board, turns, connection status)
- Standard connection metadata such as IP address, processed by Google for delivery
Rooms are for play, not profiles. We do not ask for a username. Local and AI play work without going online.
3.3 Contacting us
If you email us, we process the information you choose to send (for example email address and message content) only to respond and for related records.
3.4 Information we do not intentionally collect
- Payment card numbers (purchases, if any, go through Apple / Google)
- Precise GPS location from the Game itself
- Your contacts, photos, microphone, or camera
4. Why we process data
If you are in the EEA / UK, we typically rely on:
| Purpose | Legal basis (GDPR-style) |
|---|---|
| Provide the Game, load saves, apply settings | Contract / legitimate interests — necessary to run the product you chose |
| Host optional online rooms via Firebase | Legitimate interests / performance of the service you requested |
| Respond when you contact us | Legitimate interests / contract as applicable |
5. How we share information
Online features share room and match data with Google Firebase as infrastructure. See Google Privacy Policy.
Apple App Store and Google Play process account, download, and crash data under their terms. We may disclose information if required by law or to protect safety — only to the extent necessary.
We do not sell your personal information for money.
6. International transfers
Firebase and app-store platforms may process data in countries other than yours (including the United States). Where required, those providers may use safeguards such as Standard Contractual Clauses.
7. Retention
| Data | Retention |
|---|---|
| Local saves & settings | Until you delete the app or clear app data |
| Online rooms | Short-lived match state on Firebase; rooms expire after play |
| Emails you send us | Kept as long as needed to resolve the request, then deleted or archived only if law requires |
8. Your choices and rights
- Play locally or vs AI without using online rooms.
- Uninstall the Game or clear app data to remove local files.
- Depending on your location, you may have rights to access, correct, delete, restrict, object, or port data. Contact privacy@hyakaninteractive.com.
Because most Game progress is local (or held by Firebase / stores), we may not hold identifiable gameplay profiles on Hyakan systems. You may lodge a complaint with your local data protection authority.
9. Children
The Game is abstract board gameplay intended for a general audience. We do not knowingly collect personal information from children under 13 (or under the digital-consent age in your country where higher).
10. Security
We use reasonable technical measures appropriate to a small indie game (local sandbox storage, HTTPS for Firebase). No method of transmission or storage is 100% secure.
11. Changes to this policy
We may update this Privacy Policy. We will change the “Last updated” date above and, for material changes, provide additional notice where appropriate. Continued use of the Game after an update means you acknowledge the revised policy where permitted by law.
