Even when you run a personal blog, you still need to make sure that you comply with data protection laws. To do this, it is recommended that you have a variety of documents available on your website for visitors to view, including:
a Privacy policy (if you are collecting personal data from website users). This document should let your website users know who you are, why you are collecting their data, what you are doing with their data and how long it will be stored
a privacy notice (if you are holding and using people’s personal data). This document explains who the data controller (ie the party determining the purposes and means of processing personal data) is, who the Data Protection Officer (ie the individual responsible for ensuring data protection compliance within the business) is, and describes the purpose of collecting, using, disclosing and storing a person's personal data
a Cookie policy (if your blog uses cookies - small text files placed on a user’s computer or smartphone, commonly used to collect personal data). This should let your website users know about the website’s use of cookies. You can also have an integrated cookie policy in your Privacy policy (as is the case with Rocket Lawyer's template)
Website terms and conditions - this document governs the use of your website and to sets out the legal rights and obligations between you and your users
