Edit: I just logged in to opt out, they presented me with the switch directly. It was two clicks.
Personally, I don't mind training, as long as I have a say on the matter - and they have a switch for this. Opt-out is not exactly cool, but I've got the popup in my face, almost a month before the changes, and that's respectful enough for me.
This said, I've just canceled my subscription because this new 5-year mandatory data retention is a deal breaker for me. I don't mind 30 or 60 days or even 90 days - I can understand the need to briefly persist the data. But for anything long-term (and 5 years is effectively permanent) I want to be respected with having a choice, and I'm provided none except for "don't use".
A shame, but fortunately they're not a monopoly.
That popup was confusing as hell then, because I've read and understood it as two separate points: I've got it that they're making training opt-out, and that they're changing data retention to 5 years, independent of each other. I got upset over this, and haven't really researched into the nuances - and turns out I've got it all wrong.
Appreciate your comment, it's really helpful!
I hope they change the language to make it clear 5 years only applies to the chats they're allowed to train models on.
(Weirdly, I can't find the word "years" anywhere on their Privacy Policy, and the only instance on the Consumer Terms of Service pages is about being of legal age over 18 years old.)
