Tandem is a card game made by PandemApps. This page explains, in plain terms, what data is handled when you play — and what we simply never collect.
Tandem doesn't require any sign-up: no name, no email, no password. There's no server of ours the app connects to in order to work — matches and scores never pass through any PandemApps infrastructure.
Leaderboards, invites, and online matches rely entirely on Apple's Game Center. Your public nickname, scores, and matchmaking with other players are handled by Apple under its own privacy policy. In online matches, players' devices communicate directly with each other through Game Center.
To support free development of the app, we show ads through Google AdMob. Google may collect some technical device data to serve ads and measure their performance.
No tracking
For ad attribution we use Apple's SKAdNetwork, designed specifically to protect privacy: you're never asked for tracking permission, and we never learn who you are.
The optional "Remove Ads" purchase is handled entirely by Apple through your App Store account. We never see or store any payment data.
Tandem isn't specifically directed at children under 13, and we don't knowingly collect personal data from children.
Since we don't store personal data on servers of our own, there's nothing for you to request or have us delete. For data handled by Apple or Google, you can go directly to their own account management tools.
If this policy changes, we'll simply update the date above.
