If I buy a streak freeze and I do some duolingo what happens? Do I lose a the streak freeze?
Lets say I buy a streak freeze. Then on the next day still reach my xp goal. Will I lose my streak freeze??
No, you have the streak freeze until you miss a day you will lose it but not your streek
It sits until needed. I've had one equipped for two or three years - it's just there.
Nope. It's always there. Though it seems like you do lose weekend amulets if you don't use them? But yeah, I always have a streak freeze equipped, just to be safe =)
