Privacy Policy
Last updated: 24 May 2026. This is a plain-English summary, not legal advice — have it reviewed before you rely on it.
Fast answer
The site only asks for what the reader path needs
Email signup data is used for the free chapter and newsletter. Purchase data stays with the payment or retailer route, and support requests go through the public mailbox.
- Free sample
- First name and email only when you submit the form.
- Purchases
- Card details stay with Amazon or the approved checkout provider.
- Support
- Email us to access, correct, delete, or unsubscribe.
Data confidence
What happens before you share anything
The free sample works without payment, the policy pages are readable without signup, and every account-side route stays approval-gated until its provider is configured.
- Used for deliverySignup details send the requested files and newsletter, not cross-site ads.
- Kept out of emailDo not send card numbers, passwords, or private account screenshots to support.
- Easy exitUse the unsubscribe link or support route to correct, delete, or stop email data.
Safe support path
Know what to send before you email.
Privacy requests are easiest to action when the message names the route and the email address involved, while keeping payment details and private account screenshots out of the inbox.
Reader routes
Use these paths if you came here before choosing how to start. The free reader path avoids checkout, while the buy page shows which formats are live and which still need launch approval.
Who we are
This site (compoundingmomentum.com) is run by David Shelley to share the book Compounding Momentum and its companion workbook. Contact: hello@compoundingmomentum.com.
What we collect
- Email & first name — only if you submit the signup form, to send your free Chapter 1 and the newsletter.
- Purchase data — if you buy direct, our payment processor handles your card details; we never see or store them. Book purchases on Amazon are governed by Amazon's own privacy policy.
- Anonymous, cookieless analytics — aggregate visit counts only. No tracking cookies, no cross-site profiling.
Who processes your data
- Buttondown — email list & delivery.
- Cloudflare — hosting, security, and cookieless analytics.
- Stripe / our merchant of record — only for direct purchases (payment + tax).
- Amazon — when you buy via a retailer link.

You can unsubscribe from any email in one click. To access, correct, or delete the data we hold, email us and we'll action it. We keep email data only while you're subscribed.
Before you send a privacy request
Include the email address used on the signup form, the route involved, and the action you want: access, correction, deletion, or unsubscribe help. Do not include card numbers, passwords, private account screenshots, or retailer login details.
