If you have lost a Streak due to issues with the Classic app or website, we unfortunately can no longer restore these.
As we focus our technical efforts on our new Learn, Immerse, Communicate experience, we won't be optimising the old streaks system.
We do however have a new and more robust streaks system in place in the new experience.
If you would like to be opted into the New Memrise, please submit your email via this form and we will switch your account as soon as we can.
