#GDPR Update:
You need to update your privacy policy soon if you have not done it yet. Keep these things in mind while writing policy:
You need to make and write it in simple words as per Law so that your Blog readers can understand it.
Make a note about all the data you collect, about the ways of monetization you using ( mainly google adsense and affiliate marketing ) in it,
Make a note about the way you collecting emails. If you use any tool like mailchimp you need to write in policy that you share the email data with mailchimp :)
Do update your policy as soon as possible :)
