If I should redirecting user to browser to give some permissions then back to App with some data from browser, how can I send data from browser to app?

Standard solution for that is by using deeplink or App link. Just redirect user from browser to deeplink that your app is registered to handle. You can embed the data inside the deeplink or you can embed some token and receive the data from some service using this token as authentication

Yes, that's exactly what I want. Thanks a lot.
