For any such agreement, look for a clause that says they can change it at any time. If the other party can change the contract at will, you have no contract. Unforunately, most agreements I see with commercial vendors, especially privacy agreements, say that. Then look for clauses that say, 'we can do A or B or C specific things, or anything we deem necessary in order to ...'. Again, there's no effective contract. IANAL, so maybe there are some benefits. I wonder how much you can argue that what they do with the data you provided on Jan 14, 2022, depends on the agreement in force then.
