CardBound for Android: privacy policy
For the CardBound app on Android, from Google Play. Last updated 8 November 2026.
This policy covers the Android app only. The free version of CardBound that you play in your browser on kaydee.codes has no adverts and no purchases, and it's covered by this site's privacy page instead.
Who I am
CardBound is a card game made by me, Kaydee, an independent developer in the UK who works as KaydeeCodes. I'm responsible for this app and this policy. I don't have accounts, logins or a server, and I never see who you are. This page explains the little data that is involved and where it goes.
What stays on your phone
Your progress (cards, stars, stats and settings) and your charges are saved in the game's own storage on your phone. They aren't sent to me. If you have Android's backup turned on, Android may back that storage up to your Google account, so your progress can come back on a new phone. You can delete it at any time by clearing the app's storage or uninstalling the game.
Adverts
The free version of the app shows adverts from Google AdMob. To choose and measure adverts, and to stop fraud, Google's advertising software in the app collects and shares some information with Google:
| Information | What it's used for |
|---|---|
| Your device's IP address, which gives a rough idea of where you are | Advertising, measuring adverts, preventing fraud |
| How you interact with adverts and the app, for example app launches, taps and advert views | Advertising, measuring adverts, preventing fraud |
| Diagnostic information about how the app and the advert software perform | Advertising, measuring adverts, preventing fraud |
| Device identifiers, such as your Android advertising ID | Advertising, measuring adverts, preventing fraud |
All of it is sent encrypted. In the UK, the EU and some other places you'll be asked when you first open the game whether Google may use your data for personalised adverts. In some US states you can also ask that your information isn't sold or shared for targeted adverts. Wherever these choices apply to you, you can change them at any time in the game's Settings, under "Advert privacy choices". You can also reset or delete your advertising ID in your phone's settings.
Google explains how it uses this information in How Google uses information from sites or apps that use its services and in Google's privacy policy.
The adverts are limited to ones suitable for teenagers and up.
Notifications
If you allow it, the game can send you a notification: when your free charges are back, when a win streak is waiting, or after a few days away. The game sets these up on your phone itself, using only what's already saved there, such as your charges and streaks. Nothing is sent to me or anyone else to make them, and no outside notification service is used. Android asks you before any are shown, and you can turn them off at any time in the game's Settings or in your phone's settings.
Ratings
After a few wins the game may ask Google Play to show its own "rate this game" card, and Settings has a Rate CardBound button that opens the game's page on Google Play. Ratings and reviews go to Google Play, are covered by Google's privacy policy, and appear on the store like any other review. The game isn't told whether you rated it or what you wrote.
Purchases
Charge packs and Unlimited are bought through Google Play. Google handles the payment, and I never see your name, card or payment details. The game is only told what was bought, and keeps a note of it on your phone so a purchase can't count twice. Buying Unlimited stops all adverts, and with them the data collection above.
Your rights
I don't hold any information about you, so there's nothing for me to send you or delete. For the information Google collects through adverts, you can see and manage it in your Google account and through the links above. If you're unhappy with how your information is handled, you can contact me, and you also have the right to complain to the UK's Information Commissioner's Office at ico.org.uk.
Children
CardBound isn't aimed at children under 13, and I don't knowingly collect any information from them.
Changes
If this policy changes, I'll update this page and the date at the top.
