Privacy Policy — Ancient Chess

This Privacy Policy explains what information the Ancient Chess app (“the app”, “we”) collects and how it is used.

Summary

Ancient Chess is a single-player chess app. You can play entirely offline without an account. We do not run our own servers that collect your personal data. Some optional features rely on Google services (sign-in, ads, purchases), described below.

What we collect

1. On-device data (not sent to us). Game statistics, settings, puzzle progress, theme/engine preferences, and your purchase/entitlement status are stored locally on your device (browser localStorage inside the app). This never leaves your device and is removed when you uninstall the app.

2. Account (optional — only if you sign in). If you choose to sign in, Firebase Authentication (Google LLC) processes your email address and display name to create and secure your account. You can use the app fully without signing in.

3. Advertising. We show ads via Google AdMob. AdMob may collect a device advertising identifier and limited usage/diagnostic data to serve and measure ads. In regions that require it (e.g. the EEA/UK), we present a Google-certified consent form (UMP) before serving personalised ads. Purchasing “Remove ads” or Premium turns ads off.

4. Purchases. In-app purchases and subscriptions are processed by Google Play Billing. We never see or store your payment details; we only store a local flag indicating which entitlements you own.

Third-party services

Data sharing & selling

We do not sell your personal data. Data is shared only with the Google services above strictly to provide the listed features.

Children

The app is rated for general audiences and is not directed at children under 13. We do not knowingly collect personal data from children.

Your rights

You can play without an account, delete local data via in-app “Reset progress” or by uninstalling, and (if signed in) request account deletion by contacting us at hello@tsego.com.

Changes

We may update this policy; the “Last updated” date will change accordingly.
