I wouldn't say it's more for logging, it's most likely for analytics purposes. A/B tests, funnels (how many people who install the app launch it, how many create an account, how many swipe right, how many swipe right a bunch, how many write a message, how many write a bunch of messages, how many buy the subscription, what page did they click it off of, how 'attractive' (some arbitrary number based on how many swipe rights, possibly) was the person they decided to buy the subscription for, etc. Note, most sites that do analytics don't really care about who you are, individually, as a person, just how can they categorize you and your activities so they can generalize it and find ways to "improve the user experience" (read: improve how many users spend mucho dinero on our services). And it's gotten to the point that they're never satisfied and want as much data as they can get away with so they can analyze it from a billion angles and tell the developers to change everything about the app every other week in the chase for better numbers.
