I want to start an email referral campaign to collect emails for the upcoming launch of a videogame and was warned that I need to comply with the GDPR rules of privacy.
I'll be storing the email addresses and IP (to prevent fraud). From what I saw there is in the GDPR a legal basis to store the IP which is (f) Legitimate interests.
The user signs up with their email and then receive a link to share with friends.
Thanks for your help.
