Book updates · September 23, 2026
How the list works.
The signup form is for emails from C. Shane Rivers about The Focused Agent and its companion materials. After you submit the form, you must click the confirmation link sent to that address. The toolkit download is available only after that confirmation.
What the form saves
Your email address, the signup time, the wording version of the consent you gave, your subscription status, a confirmation state and time, and a random unsubscribe token. Your address is trimmed and stored in lowercase so repeat signups don’t create extra entries.
The confirmation link expires after 48 hours. The website stores a keyed representation of the temporary confirmation token rather than the token itself. Please use your own address and do not forward the confirmation link.
Where it goes
Records are stored in Supabase. The website runs on Shane’s server, managed with RunCloud, with Cloudflare in front of it. The confirmation email is relayed through Cloudflare to Migadu. The hosting and email providers may keep service and security logs under their own policies. Only the configured list owner can use this website’s export and list-management functions.
The signup form uses short-lived, keyed network-address hashes and a hidden field to reduce automated abuse. The application does not save your raw IP address in the mailing list. No advertising pixels or analytics trackers have been added to this page.
Leaving or removing your record
Use the unsubscribe link in a future update, or email [email protected] from the address concerned. An unsubscribed address stays on a suppression list so another form submission cannot quietly add it back. Ask Shane if you want to rejoin.
You can also request access to, correction of, or deletion of your list record at that address. A deletion request should also be applied to any earlier exports and future mailing-provider copies. Provider backups may follow a separate retention schedule.
Owner access and cookies
Readers do not need an account to use the page or request updates. The private owner area uses Supabase authentication and a necessary, short-lived sign-in cookie. The public signup form does not set a tracking cookie.
This notice covers the book signup application and the configured hosting and email services. It does not replace those providers’ separate policies.
