This document is a legal statement that indicates how your company collects and processes the personal data of shareholders and/or investors in your company, and the purposes and legal basis for this processing. For example, you might collect data in order to administer an investment and assess an application, or to conduct anti-money laundering checks.
These people are not necessarily always employees of your company, so this notice should be made available on the relevant area of your website, or sent directly to those contacts it applies to, so that the company has complied with its obligation to make data subjects aware of its data processing activities. You should not use this document for internal recruitment candidates or employees of the company, as separate policies etc will apply.
This document assumes that you are a UK-incorporated company and that English law applies.
