5 Card Mayhem: Privacy Policy

Effective 11 November 2026

5 Card Mayhem (“the game”) is made by Alper Gökalp (“I”, “me”). This policy explains what information the game uses and why. If you have a question, send me a message through the contact form.

The short version

  • The game has no accounts and asks you for no personal information.
  • Your settings, records and progress are stored only on your phone.
  • The app versions show optional rewarded ads through Google AdMob. Google collects some device and usage information to show and measure those ads. You can limit this, as described below.
  • With your permission, the app versions send anonymous gameplay statistics (such as how far a run went) so I can improve the game. You can switch this off in the game’s Settings.
  • The web version at damage-dealer.alperbey.com shows no ads.

Information stored on your device

The game saves your settings (such as sound and music), your best results, whether you have finished the tutorial and the run you are playing (so it carries on if the game is closed). This stays on your device and is never sent to me. Uninstalling the game, or clearing its data, deletes it.

Gameplay statistics (iOS and Android apps)

If you allow it (on iPhone, only if you allow tracking when the game asks; in the EEA, UK and Switzerland the game also asks about these statistics; elsewhere on Android it is on unless you switch it off), the apps send anonymous statistics about how you play: when a run starts and ends, which wave you reached, which rewards you picked, whether you reshuffled, and similar game events, with the app version and whether it’s the iPhone or Android app. They are linked to a random ID created for this install of the game, not to your name, account, advertising ID or contacts, and they are not used for advertising or shared with advertisers.

The statistics are processed for me by PostHog on servers in the European Union (Frankfurt). PostHog works out an approximate location (country and city) from the IP address the statistics arrive from; the IP address itself is not stored. They are kept for up to 2 years.

You can switch this off at any time in the game under Settings › Privacy › Share anonymous stats (on iPhone the switch appears once you have allowed tracking). Switching it off deletes the random ID from your phone; deleting the game does too.

Leaderboards (iOS and Android apps)

If you are signed in to Game Center (iPhone) or Google Play Games (Android), the game sends your best wave and best throw, and your longest Survival time, to that service’s leaderboards when a run ends. Your score is shown there with your Game Center or Play Games name. The game itself never sees your account details; Apple and Google handle the sign-in and the leaderboards as described in their own privacy policies (Apple, Google). If you are not signed in, nothing is sent. You can sign out, or hide your profile, in Game Center or Play Games.

Ads (iOS and Android apps)

The apps show rewarded ads from Google AdMob. An ad plays only when you choose to watch one. To show and measure ads and to prevent fraud, Google’s Mobile Ads SDK collects:

  • your device’s advertising identifier (on iPhone, only if you allow tracking) and other device identifiers;
  • your IP address, which gives an approximate location;
  • which ads you see and how you interact with them;
  • diagnostic information, such as crash logs and performance data.

Google uses this information as described in its privacy policy and in How Google uses information from sites or apps that use our services. I don’t receive this information in a way that identifies you; I only see aggregated reports, such as how many ads were shown.

Your choices

  • EEA, UK and Switzerland: the game asks for your consent before ads are personalized. You can change your choice at any time under Settings › Privacy › Privacy choices for ads in the game.
  • iPhone: the game asks whether it may track you. You can change this at any time in the iPhone Settings app under Privacy & Security › Tracking.
  • Android: you can reset or delete your advertising ID in your phone’s settings (under Google › Ads, or Privacy › Ads, depending on the phone).

If you don’t allow personalized ads, you may still see ads, but they won’t be based on your activity in other apps.

The web version

damage-dealer.alperbey.com is hosted on Cloudflare, which processes visitors’ IP addresses to deliver the site and protect it from attacks. The web version has no ads and no analytics, and stores your progress only in your browser. It sends no gameplay statistics.

Children

The game is not directed to children under 13, and I don’t knowingly collect personal information from them.

Changes

If this policy changes, I’ll update it on this page and change the date at the top.
