Is the consent of the user required for the processing of personal data?

Question

Personal Information

Good afternoon!
Tell me please!
There is a registration form on the site: Fields
: Made-up nickname, email and password
is not obliged to store this information on Russian servers, right? And if you add to these fields, for example, the city of residence without specifying the address, just the city?
There is also authorization through services such as google, linkedin, I also take only my nickname and email for storage, nothing more.
Can I be required to add a checkmark to the form with the user's consent to the transfer and processing of personal data? And demand to keep this data on Russian servers and will this requirement be legal?

Answer 1

There is also authorization through services such as google, linkedin, I also take only my nickname and email for storage, nothing more.

I forgot to mention the ID that the service returns.
