So, that newsletter is going to be the only thing that I gather information from on here. I won't be passing it on to anyone else, selling it, or doing anything untoward with it. If you're lucky, the most I might do with it is occasionally send you a newsletter. If you want to be removed from it, just let me know or click the handy 'unsubscribe' link that'll be on each one.
With regards to any other data, if you use the contact form, it'll go to my email and that's basically it. I'm not gathering or storing any other data. The only third-party that's used in anything is my web-host, which is GoDaddy, and it's their back-end stuff that allows things like email subscription and contact form to work. You'll be able to find out more about how that all works on their site if you're so inclined.
TL:dr - I'm not gathering any information about you. You'll have to actively tell me you want me to take any of your data by subscribing to my newsletter or contacting me directly, and it'll be easy to unsubscribe if you want to do so.
