Wait until GDPR kicks in on May 25, 2018. ANY company that collects data on EU citizens (Name, phone number, email adress, geo location) will be required to comply or be subject to 20 million euro fines. So your Apple Store app that you offer for free because you use it to collect data? You must hire a Data Protection Officer (DPO)and be able to erase a user's data on request. I predict that will lead to blocking EU citizens from many services outright to avoid having to comply with an onerous regulation.
