Give the Article 17 notice before processing in a prominent, clear, accurate, and complete form. When relying on consent, make it informed, voluntary, and explicit, provide a convenient withdrawal method, and obtain new consent if the purpose, method, or personal-information categories change.
Sensitive personal information needs a specific purpose, sufficient necessity, strict protection measures, a notice explaining necessity and impact, and separate consent unless another legal rule controls. Information about a child under 14 is sensitive; obtain the parent or other guardian's consent and use dedicated processing rules.
