Privacy Policy

Shatranj: Offline Chess AI  ·  by Bolbytech

Effective Date: September 13, 2025

In plain English: Shatranj is a fully offline chess game. It does not connect to the internet, collect any personal data, display ads, or share anything with anyone — ever. Your game is stored only on your device.

1. Overview

This Privacy Policy describes how Bolbytech (“we”, “us”, or “our”) handles information in connection with the Android application Shatranj: Offline Chess AI (package name: com.bolbytech.shatranj).

Because Shatranj is a fully offline, single-device application with no internet connectivity, no user accounts, and no third-party services, this policy is straightforward: we collect no personal data whatsoever.

2. Data We Do Not Collect

Shatranj does not collect, transmit, or store any of the following:

Personal Information No name, email, age, location, or identity of any kind.
Location Data No GPS or network-based location is ever accessed.
Usage Analytics No crash reports, telemetry, or behavioral analytics.
Device Identifiers No IMEI, advertising ID, or device fingerprinting.
Game History Completed games are deleted immediately from the device.
Network Requests The app has no Internet permission and makes zero network calls.

3. What Is Stored Locally on Your Device

Shatranj stores a small amount of data in your device’s private app storage using Android SharedPreferences. This data never leaves your device.

  • Settings – your chosen theme (dark/light), sound, haptics, animation, and legal-move display preferences.
  • Active game state – the current unfinished game’s mode, difficulty, player color, and move list, so the game can be restored if you leave mid-game.

Completed games are erased from storage as soon as they end. Android cloud backup is explicitly disabled, so your data is never uploaded to Google’s backup servers. Uninstalling the app permanently removes all locally stored data.

4. Internet Access & Permissions

The Android release manifest for Shatranj does not include the INTERNET permission. This means the operating system itself prevents the app from making any network connection — not as a policy choice, but as a hard technical constraint.

  • No internet permission declared in AndroidManifest.xml
  • No third-party SDKs (advertising, analytics, or crash reporting)
  • No remote images or remotely hosted fonts
  • No account system or authentication
  • No in-app purchases or payment processing

5. Third-Party Services

Shatranj does not integrate any third-party services, SDKs, or libraries that access the network at runtime. The only runtime dependency is Google Fonts, used solely to select fonts that are bundled locally with the Flutter framework — no network request is made to Google Fonts servers after installation.

The app is distributed through the Google Play Store. Google may collect certain information as part of the Play Store platform (such as installation statistics). This is governed by Google’s Privacy Policy, not this policy.

6. Children’s Privacy

Shatranj is suitable for all ages. Because the app collects no personal data from anyone, there are no special concerns regarding children’s privacy. We do not knowingly collect information from children under 13 (or the applicable age of digital consent in your jurisdiction) or from users of any age.

7. Data Security

Since no personal data is collected or transmitted, there is no personal data at risk of a breach. The minimal local game state is stored in Android’s private SharedPreferences, which is sandboxed by the Android operating system and inaccessible to other applications.

8. Changes to This Policy

We may update this Privacy Policy if we make changes to the app that affect how data is handled. If any future version of Shatranj introduces data collection of any kind, this policy will be updated and the new effective date will be noted prominently. We encourage you to review this page periodically.

Continued use of the application after any changes constitutes your acceptance of the updated policy.
