Users who are uncertain about which Personal Data is mandatory are welcome to contact the Owner.

Any use of Cookies – or of other tracking tools – by this Application or by the owners of third party services used by this Application serves the purpose of providing the service required by the User, in addition to any other purposes described in the present document.

2. On our servers: send a “Data erasure” request by email to blackhandservice2120@gmail.com. Please include the email address of the Google or Apple account you use to sign in, or your player ID (shown as UID on the Friends page) if you have never signed in, so we can find your data.

Advertising measurement

The Owner advertises this Application on Meta's platforms, such as Facebook, Instagram and Threads. The service in this section lets the Owner find out which of those ads led to an installation or a purchase, and helps show those ads to people who are more likely to be interested in them.

Meta App Events (Meta Platforms, Inc.)

This Application uses this third party technology to collect the following information and share it with Meta: that this Application was installed and opened, the product identifier, amount and currency of in-app purchases that have been verified, unique device identifiers for advertising, an anonymous identifier for this installation, and information about the device (such as the device model, operating system version, language and time zone). Your payment details are not included. This Application does not use Facebook Login and does not read anything from your Facebook or Instagram account.

Third parties, including Meta, may collect or receive information from this Application and other apps, and may use that information to provide measurement services, target ads and deliver ads. For how Meta handles this information, see its Privacy Policy linked below.
