Organisations must, in the case of direct collection of personal data from the individuals concerned, provide information about the processing operations in a concise and transparent way, using understandable, easily accessible and clear and plain language. This can be done in writing (e.g. on the reverse side of a tender) or by electronic means (e.g. on a website). If the person concerned so requests, you may also provide this information orally, but you must be able to prove this afterwards.
Even when the data was collected indirectly, i.e. if you do not directly collect the personal data from an individual yourself, but for example via a third party, you must provide the same detailed information to individuals
