If you would like to revoke your consent to data processing by Mika and your data stored by Mika should be deleted, you can revoke your consent to data processing in the Mika app via Settings > Delete user account - without affecting the legality of the data processing that took place before the revocation and thus block your account.

After the deadline, the data will be deleted.

The blocking cannot be undone.
