What type will the consent field (checkbox) be?

The consent field, presented as a checkbox, usually has a boolean data type, as it reflects two states: agree (true) or disagree (false).

In databases, this can be of type BOOLEAN or TINYINT(1) (depending on the DBMS). In the user interface, the checkbox displays the user's choice, and in analytics or business logic systems, this field is interpreted as a consent flag.

Example in SQL:

CREATE TABLE users (
    id INT PRIMARY KEY,
    name VARCHAR(100),
    consent BOOLEAN NOT NULL DEFAULT FALSE
);

Such a field is convenient for checking whether the user has given consent for data processing or subscription.
