I want this for my contact address book too. “This app would like to know all your contacts. Allow / send empty contact list / generate garbage data”

I’d also enjoy if my advertising cookies were randomly reused by people all over the globe. And I’d like my phone number and email address to get associated with dozens of other identities.

there is an alternative contact app that doesn't share your data. you can then fill the default contact app with fake data or leave it empty.

i am not sure if the last point is a good idea though. i get what you want to achieve. anonymity in numbers and plausible deniability, but you are more likely to get mixed up with problematic stuff others are doing rather than protecting yourself. having a common name already shows that. it is both a blessing and a curse.

You may want to share your contacts with app X but not with app Y, though.

yes, fair point. i solve that by using shelter where the app and a contact app run with an independent configuration. the downside is that i have to duplicate contacts in the shelter vs outside. however that is what i want because not all contacts are duplicated.
