No.
LANDR works for music creators. We don’t take any of your rights or royalties when you release with us. Just like our mastering services, you’ll keep all ownership of your music before and after releasing.
You keep 100% of your rights, royalties and soul.
The only things we’ll deduct from your income are any fees we’re required to pay in order to get your money back to you (for example, currency conversion fees).
