Privacy

Cookies

This site sets no cookies. There is no advertising network, and no embedded third-party script that would set one on its behalf. Signing in does not set one either.

A few small values are stored locally in your browser, using localStorage rather than cookies, and clearing your browser data removes them: your theme preference, whether you dismissed the cookie notice, and — only if you sign in — your sign-in session. The first two never leave your browser. The session is sent to the account service described below each time the app loads your account, and to nothing else.

Accounts

Making an account is optional. Every essay and every public page works without one; an account only opens the app area.

An account holds your email address, the name you give, a password, and a profile picture if you upload one. Accounts are run on Supabase, a hosted database and sign-in service: your password is stored there as a one-way hash, never in a form anyone can read back, and sign-in and password-reset emails are sent through it. Your picture is stored there too, at an address that is not secret — anyone with the link can see it, as with a profile picture anywhere.

The database is set up so that each account can read and change only its own record. Nothing in your account is shown to other users, sold, or used for anything except signing you in and showing you your own profile.

To delete your account and everything stored with it, email the address at the foot of this page from the address you signed up with.

Analytics

There is no analytics script on this site. No page-view tracking, no session recording, no heatmaps, no fingerprinting, and no advertising or social pixels.

Server logs

The site is hosted on Vercel, which records standard server logs for the requests it serves — IP address, user agent, the URL requested, and a timestamp. That is ordinary infrastructure logging, common to essentially every website, and it is used for operations and abuse prevention rather than for building a profile of you. Those logs are held by Vercel under its own retention policy.

The newsletter

The email edition is hosted on Substack. This site does not collect email addresses for it — the link on the newsletter panel takes you to Substack, and everything from that point on happens there, under Substack’s privacy policy rather than this one. Substack does set cookies; this site does not.

That link is a plain link, not an embedded widget. Nothing from Substack loads on these pages, so visiting this site does not put you in touch with them at all unless you choose to click through.

The contact form

The enquiry form on the speaking page sends what you type to a single mailbox as an email. It is not stored on this site — it does not touch the account database, and no record of the enquiry lives here once the message has been sent.

Your address is used to reply to you and for nothing else. It is not added to the newsletter list, and it is not shared. Please do not send confidential, client-privileged, or market-sensitive material through it.

The RSS feed

The feed at /rss.xml is a plain file. Subscribing to it in a reader tells this site nothing beyond the ordinary server log entry described above, and requires no email address.

Questions

Email speaking@powerfundamentals.com to delete your account, or if something on this page does not match what you observe. The newsletter list is Substack's, and every issue carries its own unsubscribe link.
