Privacy Policy

Last updated: September 13, 2026

At OnlineCardGames.io, we take your privacy seriously. This policy describes how we treat your information.

Information We Collect

We do not require you to create an account to play our games. We may collect anonymous usage data to improve our services.

Anonymous Game Research

We measure when a game starts and whether that play ends in a win, loss, completion, or abandonment, together with approximate duration and moves. This helps us publish aggregate research and improve game design.

This research measurement does not store your name, email address, account ID, IP address, or full browser user agent. A random temporary game-session ID is used only to match a start with its outcome; it is not used to follow you across games or visits. We publish only aggregate results and require a minimum sample before showing a game in a comparison.

Cookies

We use local storage to save your game progress and settings. We may use cookies for analytics purposes.

Private Multiplayer Tables

Hosting a private table requires an account. A friend using an invitation link can join with a temporary display name. Other signed-in players can find your public username to invite you. You can decline invitations, block a sender, or turn invitations off from the Friends panel.

We use a temporary, secure session cookie to reconnect you to your seat. Game state and the latest 40 text-chat messages are stored on our Cloudflare infrastructure while the table is open. Chat is shared with the other player and is not end-to-end encrypted. Active table data is deleted when the table closes or expires, within four hours at most. Cloudflare may retain provider-managed recovery copies under its retention settings.

Invitation preferences and blocked-player settings are saved to your account. Temporary invitation records and request counters help prevent spam and control usage. Invitations expire after 20 minutes. You can mute chat locally without leaving your game.

Friends and Profile Photos

Friend connections are added only after a request is accepted. Your friend list is available in your own Friends panel. Pending friend requests expire after seven days. We use browser storage to remember read notifications and dismissed alerts, and to share that state between your tabs.

Your chosen player name and country flag are public. Profile photo uploads are optional. Your browser sends only a small cropped image, and the server creates a new image without the original file metadata. Pending photos are private and available to authorized moderators for review. Approved photos can be shown on your profile, in games and on leaderboards.

You can remove uploaded photos in your profile. Rejected photos are deleted when reviewed. Unreviewed photos expire after seven days and are removed by scheduled cleanup. Cached copies of approved photos may remain visible for up to five minutes after removal.
