This page covers the ProofOfSolve email list. When paid puzzles launch, this page will be expanded to cover purchases and answer submissions before any of that goes live.
What we collect
- Your email address.
- The date and time you signed up.
- The country your connection came from, which tells us roughly where interest is coming from.
We don't store your IP address with your signup, and we don't use tracking or advertising cookies on this site.
How we use it
Only to email you about ProofOfSolve: launch dates, new puzzles, winners and payouts. We never sell or rent your email address, and we don't share it with advertisers.
Where it's kept
The list is stored in a database we control on Cloudflare. When we send emails, we use an email delivery service that handles the message on our behalf and nothing more.
Unsubscribing and deleting your data
Every email includes an unsubscribe link. You can also email support@proofofsolve.com and ask us to remove your address completely.
