Thanks for your feedback. As this is an important security feature, we have asked the community how they would like to see this feature in detail: https://www.reddit.com/r/tutanota/comments/8abisz/new_client_stores_your_ip_address_encrypted_for/
As you requested, in the future the IP log feature must be atcivated by the user to guarantee everyone’s need for privacy is respected. We have now started this feature so we can change the encrypted IP log feature to opt-in before pushing the new client out of beta.
If you want to support our fight for privacy, please upgrade to Premium for only 1 € per month. :) Thank you!Horrible commented
Oh.. That data is encrypted and only you can see it! Untill you compromise your password...
If you don't want that shit then log in to beta via tor and then never use beta client, instead use the stable one till they implement a feature to turn it off.
