Guidelines 05/2020 on Consent under Regulation 2016/679 (GDPR)
Paragraph 3.1.3 Granularity
42. A service may involve multiple processing operations for more than one purpose. In such cases, the data subjects should be free to choose which purpose they accept, rather than having to consent to a bundle of processing purposes. In a given case, several consents may be warranted to start offering a service, pursuant to the GDPR.
43. Recital 43 clarifies that consent is presumed not to be freely given if the process/procedure for obtaining consent does not allow data subjects to give separate consent for personal data processing operations respectively (e.g. only for some processing operations and not for others) despite it being appropriate in the individual case. Recital 32 states, “Consent should cover all processing activities carried out for the same purpose or purposes. When the processing has multiple purposes, consentshould be given for all of them”.
44. If the controller has conflated several purposes for processing and has not attempted to seek separate consent for each purpose, there is a lack of freedom. This granularity is closely related to the need of consent to be specific, as discussed in section 3.2 further below. When data processing is done in pursuit of several purposes, the solution to comply with the conditions for valid consent lies in granularity, i.e. the separation of these purposes and obtaining consent for each purpose.
45. Example 7: Within the same consent request a retailer asks its customers for consent to use their data to send them marketing by email and also to share their details with other companies within their group. This consent is not granular as there is no separate consents for these two separate purposes, therefore the consent will not be valid. In this case, a specific consent should be collected to send the contact details to commercial partners. Such specific consent will be deemed valid for each partner (see also section 3.3.1), whose identity has been provided to the data subject at the time of thecollection of his or her consent, insofar as it is sent to them for the same purpose (in this example: a marketing purpose).
