Anarchy Chess Privacy Policy

Cymatics LLC · Last updated October 27, 2026

Anarchy Chess is a card-driven chess game made by Cymatics LLC, on the web at anarchychess.fm and as an app for iPhone, iPad and Android. This page explains what the game collects, why, and what you can do about it. Short version: no ads, no selling your data, no tracking you across other companies' apps or websites.

Your account

You can try the game and its tutorial without an account. To play matches, open packs and keep a collection, you sign in with Apple, with Google, or with your email address and a 6-digit code we email you. For your account we keep:

• Your email address (with Sign in with Apple, this can be Apple's private relay address) and the account identifier Apple or Google gives us. If Apple or Google shares your name when you sign in, our sign-in provider stores it with your account; the game never shows it — other players see only the username you pick.
• Your username and your profile, your saved decks, your collection, packs and other game items and progress, your settings, your friends, your online match results and your leaderboard rating.

We use these to run your account, to sign you in (the codes), to keep your game in sync across your devices, and for the leaderboard and friends. We email you only about your account (for example, sign-in codes).

Gameplay and usage statistics

To balance the cards, fix bugs and improve the game, it records gameplay and usage statistics: matches played and their results, the cards and decks used, packs opened and what was in them, the screens and features used, errors, and basic device information (device model, operating system, app version, language, time zone and screen size), with a random ID for your installation. When you're signed in, these records are linked to your account. On the website we also note where a visit came from (the referring site and any campaign tags in the link). Settings → Share game stats turns this off. "Report a problem" in Settings sends us a report with your recent game log so we can find the bug. These statistics aren't used for advertising and aren't sold.

Playing online

In an online match the game sends the moves, your username, the deck you play with (and its card art and sleeve) and the game's state to your opponent's device, through our game server or through relay and peer-to-peer connection services. Results of online matches between players with accounts are kept for the leaderboard and your rating.

Messages between friends

When direct messages are available in the game, you can send text messages to players you're friends with (both of you have accepted the friendship). This is how they work:

• Not end-to-end encrypted. Your messages are stored on our servers (our database provider) so they reach your friend on any of their devices, even when they're offline. Your friend can read the messages in your conversation, and so can the Anarchy Chess team.
• The team may review them. The Anarchy Chess team can read any conversation to keep players safe: for example to review a report, to look into harassment, hate or threats, or to settle a dispute. Messages aren't used for advertising and aren't sold.
• Filtered. Offensive words are hidden from the person you're messaging. When the filter changes a message, we also keep the text as it was typed, so our team can review it.
• Reports and blocking. If you report a message or a conversation, our team sees your report and reads the conversation. You can block a player: they can't message you or send you friend requests, you're no longer friends, and they aren't told.
• How long we keep them. Messages are deleted automatically 12 months after they're sent, except a message that someone reported, which we keep until our team has reviewed the report. Reports are deleted 12 months after they're reviewed.
• Deleting your account (Settings → Account → Delete account) deletes your conversations and every message in them, your blocks and your reports straight away.

Notifications

When notifications are available in the game and you allow them, we keep a notification token for your phone or browser (from Apple, Google or your browser's push service) with your account, together with your time zone, your game language, the hour you usually play and your notification settings. We use them only to send you game notifications: a free pack is ready, a daily reminder (at most one a day, never at night), and messages from your friends. A message notification shows your friend's name and their message, and is delivered by Apple, Google or your browser's push service. You can turn each kind off in Settings, or all of them in your phone's or browser's settings. Logging out removes the token from your account; deleting your account deletes all of it.

No ads, no selling, no tracking

The game has no ads. We don't sell your data and we don't use it to track you across other companies' apps or websites. We share it only with service providers that run parts of the game for us, under agreements that limit them to that: our database and sign-in provider (Supabase), our website host (Vercel), our game server host (Fly.io), the online relay services the matches use, and Apple and Google for signing in and notifications.

What stays on your device

Your settings (sound, music, language), your decks and the game you're playing are also saved on your device so the game opens quickly and works on a weak connection. Deleting the app (or clearing the website's data) removes them from that device.

Delete your account

In the app or on anarchychess.fm: Settings → Account → Delete account, then type "delete" to confirm. It happens right away.

Without the app: email steven@cymatics.fm from the email address on your account (or tell us your username and how you sign in) with the subject "Delete my Anarchy Chess account". We delete it within 30 days and reply when it's done.

What's deleted: your account and email address, your sign-ins (Apple, Google, email), your username and profile, decks, collection, packs, items and progress, friends, messages, blocks and reports, match history and rating, and notification tokens. What's kept: gameplay statistics, no longer linked to your account. Our database backups roll over within about a week.

Children

The game isn't directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we'll delete it.

TestFlight

If you test a pre-release version through Apple's TestFlight, Apple may share crash reports and feedback you choose to send with us, under Apple's privacy policy.
