You have the right to ask the Parish Council whether or not they are using or storing your personal information.
This is called the right of access and is commonly known as making a subject access request (SAR)
Under Article 17 of the UK GDPR individuals have the right to have personal data erased. This is also known as the ‘right to be forgotten’.
The right only applies to data held at the time the request is received. It does not apply to data that may be created in the future. The right is not absolute and only applies in certain circumstances.
