Privacy Policy

Last updated: 5 October 2026

Overview

Chess Classica ("the app", "we") is a chess game for Android that you can play offline. An account is optional. This policy explains what the app stores, what leaves your phone and why. It applies to the app and to this website.

Data stored on your device

Your games, statistics, coins, achievements, settings and profile (name, country, chosen avatar or photo) are saved on your device. Without an account they stay only on the device and are deleted when you uninstall the app or clear its data.

Optional account

You can log in with Google or with an email address and password (Firebase Authentication by Google). With an account, your name, email address, profile (name, country, avatar and profile photo, if you upload one), coins, ratings and game history are backed up in Google Firebase so you can restore them on another phone. Your profile photo is only taken from your gallery when you choose one, and is resized to a small image first.

Online play

To play online, the app uses an anonymous Firebase session and shares your player name, country, chosen avatar piece, online rating and win/draw/loss record with other players while you are in the online lobby. The moves of online games are stored only while the game runs and are deleted shortly after it ends.

Analytics and crash reports

The app uses Firebase Analytics (which screens and features are used, e.g. "puzzle solved") and Firebase Crashlytics (crash and error reports with device model and Android version) to fix bugs and improve the game. These do not include your name, email address or photo. Feedback you send from Settings is stored with your message.

Advertising

The app shows ads through Google AdMob: a video when a match starts and when it ends, after every few solved puzzles, optional reward videos and small banners on menu screens. Ads never appear during a game. Google may collect and use your device's advertising ID, IP address and basic device information to show and measure ads. In the EEA, the UK and Switzerland you are asked for consent first, and you can change your choice at any time in Settings → Privacy choices. You can also reset or delete your advertising ID in your Android settings. See how Google uses data in ads.

Notifications

If you allow notifications, the app schedules reminders on your phone (for example, your daily gift). They are created on the device; no data is sent to do this.

Purchases

Optional purchases (coin packs, Remove Ads, design packs) are processed by Google Play. We never see or store your payment details. Coins are virtual items with no cash value.

Sharing

We do not sell your data. Data is processed by Google (Firebase, AdMob, Google Play) as our service providers, under Google's privacy policy. All data is sent over encrypted connections (HTTPS).

Data retention

• Account data is kept until you delete your account.
• Online lobby entries and game moves are removed when you leave or shortly after the game ends.
• Analytics and crash data are kept for at most 14 months.

Deleting your data

• In the app: Profile → Edit profile → Delete account deletes your account and its cloud backup (stats, games, photo) at once.
• Without the app: see how to delete your account.
• Data on your phone is removed when you uninstall the app.

Children

The app is not directed at children under 13 and we do not knowingly collect personal information from children. If you believe a child has given us personal information, contact us and we will delete it.

This website

This website does not use cookies, analytics or ads. Our hosting provider (Netlify) may keep standard server logs, such as IP addresses, for security.

Changes

We may update this policy. The date at the top shows the latest version.
