This is why a contract should not be legally binding if it's unclear. I don't mean "clear to a lawyer", but what the common person, spending the standard, common amount of time, with the advice you expect them to have[1], would think of as "clear". EU Data Protection law (like the GDPR) helps here, requiring informed consent. If you don't understand something, then you're not informed, and it shouldn't be binding. [1] When (say) signing a form for surgery, the surgon can presume that the person has been advised by a doctor. When buying a house, you can presume a lawyer was involved, etc. When signing a ToS for Facebook, we all know there was no legal advice recieved.
