I take your privacy seriously and here's how I use any of your personal data.
Daily WhatsApp Briefing. To send out this briefing I require a phone number. This is the only piece of information used. I use a WhatsApp Broadcast List to send the briefing and phone numbers are stored on the device used to administer it. I don't use your phone number for anything other than this.
Contact. The contact form on the site requires your email address. The details entered are emailed directly to me using the built in form. The details you provide here will not be used for anything other than replying to the contact.
