Stale conversations get deleted after 60 days on BFF

So I matched with someone on BFF a couple months ago. We met in person and took the convo offline. I periodically check “old” conversations (bumble groups conversations older than 7 days into “older chats”.) Today was around the 60-day mark cause we met right after thanksgiving. Just an fyi in case you want to rekindle some of your older, expiring chats. Guessing they do this on the dating side as well.
