7. Is your consent needed?

Suppose you apply for a supermarket loyalty card. The supermarket will need to store and process your personal details as part of their normal work. They do not need your consent to do this as you have agreed to this when you applied for the card.
However, the supermarket cannot pass your details on to another company without your consent. In practice this means that when you fill in the application form you can tick a box to prevent your personal details being sold on to another company, for example direct marketing.
Note:
- If you cancel the card, your details are no longer needed and should be deleted by the supermarket
- At any time you can write to an organisation that is sending you junk mail asking them to stop processing any data about you.
