We never recommend our users to delete a contract. A contract is a legally binding document and even if it is cancelled, it is good to keep. Especially when it’s digital and we store it for you free of charge!
However, if you for some reason still wish to delete a contract we need a written approval from both parties e-mailed to firstname.lastname@example.org. Make sure the e-mail is sent from the same e-mail address as you used to sign the contract and include a reference to the contract you want deleted.
