Any way to reset really all data?

hi there,

I have a question. I have about 1000 items for review and I already clicked multiple times the buttons to reset all grammar and all vocab. As well as in the mobile app and via website.

except the xp, level and this kind of stuff which I care 0 about in general the items keep due. All of them.

Cause the amount of due items is so high it is no option to do this manually for each card.

Also deleting the account is no option cause I bought a lifetime membership on this account.

Is this really not possible to do? Actually I cannot believe regarding a space repitition software.

Maybe I do something wrong?

Can anyone help me out?

I would appreciate it
