If your device is regularly used by someone other than yourself, it is a good idea to restrict in-app purchases within the app. You can disable in-app purchases using the below instructions:
You can set up authentication tools for your Apple account that mean a password is required when making an in-app purchase (we would probably advise against using TouchID or FaceID). It's also worth making sure that the option for your password to be required on all in-app purchases is also enabled.

To disable in-app purchases, please follow the below steps to prevent purchases being made on your device without your permission:
- Open Google Play
- Tap the Menu icon and then select “Settings”
- Tap “Require authentication for purchases”
- Select “For all purchases through Google Play on this device”
- Enter your password when requested
There are three purchase authentication options available in the Play Store app:
For all purchases: Authentication is required for every digital content purchase through Google Play (including within apps) on your device.
Every 30 minutes: Every time you authenticate for a purchase, you can continue to buy all forms of digital content through Google Play (including within apps) for the next 30 minutes without authenticating again.
Never: Disabling authentication may result in unauthorised purchases. You assume responsibility for all charges.
You can turn off In-App Purchases on your Kindle Fire by following these steps:
- Swipe down from the top of the screen to open Quick Settings
- Tap More
- Tap Applications
- Under Amazon Applications, tap Apps
- Tap In-App Purchasing
- Ensure the box next to Allow In-App Purchases is unticked
Note: If you have multiple Kindle Fire devices, you will need to complete these steps on each device.
