If it's free you are the product.
I was given information on this offer for free indie cinema tickets, apparently on market research basis but after signing up I felt increasingly uncomfortable with the sheer amount of data harvesting involved. Also, to bring a guest entails yet more data harvesting, which seems incredibly dangerous since almost every small business falls victim to data breaches. There is no way to delete an account via the Cinematik website. I am currently dealing with an AI chat bot having no human interaction, no email address or phone number for a company that wanted every bit of information about me. Ridiculous.
