What is our legal basis for using your data?

In order to hold and process your data we are obliged to identify the lawful basis upon which we do so. The lawful basis is different for the different purposes identified above.

Purpose: Informing Members and Supporters of Hackney Green Party Activities and campaigns

Lawful Basis: Public task

We process this personal data on the basis that we ensure that we communicate effectively with actual and potential supporters of Hackney Green Party and its campaigns. This ensures that we can continue to represent supporters views in a democratic way and to help us generate revenue to fund our political activities.  This processing is considered to be fundamental to our role in promoting democracy in the public interest.

Purpose: Communicating with Members about their membership and constitutional role within the Party.

Lawful Basis: Public task.

We process your membership and personal data with respect to your membership position inline with the constitution of the Party and your agreed participation. As a membership organisation we require that we be able to communicate with members about constitutional issues (such as leadership elections, conference and changes to the constitution) this is considered to be a fundamental part of our role in promoting democracy in the public interest.

Purpose: Fundraising 

Lawful basis: Public task.

We may from time to time contact you directly asking for donations to help fund the work of the Party.  Without funding it would be impossible to function as a Political Party and therefore such communication is considered to be a fundamental part of our role in promoting democracy in the public interest.
