The Endomondo app is a doozy. They require opt-in to two items to carry on using the app, but then also say that by clicking continue, you're agreeing to their privacy policy, which indemnifies them against GDPR. It's slightly clever misdirection, in my opinion. I clicked 'OK' in the end because the EULA appears to be invalid anyway; by borking the consent process they have no legal basis for processing my data.
