Privacy policy

Last updated October 14, 2026.

Calculator inputs

Calculator pages run in your browser. The numbers you type are not sent to WealthCompounds and are not stored on an account, because there is no account. A shared link only contains what the page puts in the query string on your device.

POST /api/coast-fire will compute the same Coast FIRE math if you call it yourself. The pages on this site do not call it. If you do, that request includes the figures you send. Do not send a request you would not want on a server log.

Analytics and advertising

In production the site can load Google Analytics 4 (measurement ID G-CESLWS448R) and Google AdSense (publisher ca-pub-5455802286602960). Both scripts are added after a scroll, click, or key press, not in the initial HTML fetch.

Analytics is used to see which pages are used. AdSense may set cookies and use them under Google's policies to show ads. You can block or delete cookies in your browser. Google's policy is at https://policies.google.com/privacy.

Workbooks and the waitlist

When a buy button is shown, it goes to a Stripe Payment Link. Card details are handled by Stripe, not typed into this site. Stripe's privacy policy applies to that checkout.

If the payment succeeds, this server reads that checkout from Stripe and builds a download link that expires after seven days. It emails the link to the address on the checkout using Resend. Stripe event ids are stored so a repeated notice does not send a second email. The server does not keep the message, the card, or a customer account. The confirmation page can show the same kind of link while Stripe still returns the paid checkout. Resend's privacy policy applies to that email.

If a product is not on sale yet, the products page offers a waitlist form. Submitting it checks the address format and replies that the list is not connected. This version does not store the address and does not add you to a mailing list.

Children

The site is not directed at children under 13, and it does not knowingly collect their personal information.

Changes

When this policy changes, the date at the top of the page changes with it.
