You really shouldn’t make definitive decisions about which privacy products to use based on this information alone. In this case, it has distracted you from paying more attention to the critical vulnerability that exists in 2FAS by design, which is why Techlore and Privacy Guides don’t recommend 2FAS. You should read the full privacy policy if this is an aspect that concerns you.
In the case of Ente, they mention contact information because you can optionally register for their service with your email address or send them support requests. They also mention user content because that is what they store when you create an Ente account and store your TOTP codes end-to-end encrypted on their servers. Identifiers include “information about your internet connection, IP address and user agent details.”
Now, if we look at 2FAS, they collect your device-related identifiers: “Device ID (including brand, model, unique ID, operating system info, and storage state).” They also state that they use Google Analytics for their analytics, but I haven’t been able to confirm that. However, their application connects to several Google domains, and even turning off analytics didn’t stop them all.
As we can see, the conclusion should be different if you pay attention to the relevant stuff, and read the actual privacy policy if needed.
