Which GDPR legal basis will you use if you use Google Analytics on your website or app? If you use consent, then how will you - without risking to get a consent refusal - explain to your users that Google uses your end-users’ personal data to: - track and analyse their use of your website or app, - provide you with reports about their use of your website or app, - share reports about their activities with other Google services, and - personalize adds to them (elsewhere) based on Google’s tracking of their activities on your website or app?
