Momentum mailing list — privacy notice

Updated 30 September 2026. This notice covers the website signup and early-access enquiries. Read the separate iPhone app privacy notice for your app library.

Momentum is developed by Sam Radford. Contact momentum@samradford.com about the mailing list or your information.

Signing up for updates

When you enter your email address and choose Keep me posted, this website sends it directly to Mailchimp to request occasional Momentum updates. The website’s signup code does not save your address in local browser storage. Mailchimp handles the signup and email delivery and receives network information such as your IP address. Its processing is described in Mailchimp’s privacy statement.

The current signup flow asks you to check your inbox to confirm. Follow the instructions in any confirmation email you receive. You can unsubscribe using the link in an update email, or contact Sam for help.

Early-access enquiries

The mailing list is for news and does not reserve a beta place or send a beta invitation. The early-access link opens an email enquiry. Information you choose to send is used to respond to your enquiry and discuss possible participation. Momentum is being tested privately; invitations and availability are separate from newsletter signup.

Questions

Contact Sam if you want help unsubscribing or have a question about your mailing-list information. Avoid sending app-library archives or sensitive personal information in an early-access enquiry.
