Privacy notice
Short version: we don't run accounts, ads or tracking cookies, and we don't collect your email yet.
What this site collects
- No accounts, no tracking cookies, no advertising trackers. We don't run an analytics script.
- The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical request data (such as IP address and browser type) to deliver and protect the site. See Cloudflare's privacy policy.
- The calculator asks your browser to fetch live network data and the BTC price from mempool.space, so mempool.space sees that request. Nothing you type into the calculator is sent anywhere; it stays in your browser (and in the link, if you choose to copy one).
Newsletter
The newsletter isn't open yet, and the signup form is switched off. When it opens, we'll ask only for your email, use it only to send the newsletter, and name the email provider that stores it here. Every issue will have an unsubscribe link.
Emails you send us
If you email us (for example to report a wrong price or submit a solo block), we'll use what you send only to deal with it, and won't publish your details without asking.
Links to stores
When you follow a link to a store, that store's own privacy policy applies. No affiliate links are active yet; if we add them, the store may learn that you came from LittleHash.
