Everybody can read about that in their transparency report on their website
https://threema.ch/en/transparencyreport
And they give out 2 Informations about a Threema-ID:
1. Date (without time) of the Threema ID’s creation
2. Date (without time) of Threema ID’s most recent login
These are the ONLY 2 Information they store!
The following information is only available if the user has chosen to use the respective optional functionality:
Only in case the user in question has chosen to link a phone number and/or email address with their Threema ID: Hash of the user’s phone number and/or email address
Only in case the user in question has chosen to use a third-party push service (and their ID was active within the last three months): Push token
So what....
