Railwize is a website testing interest in a learning product that is still being built. It collects as little as it can: an email address if you join the early-access list, and anonymous usage events only if you say yes to them.
Last updated 17 September 2026
What we collect, and why
- Your email address
- Only if you join the early-access list. Used to send a confirmation email, one welcome email, and an invitation when early access opens. Never sold, shared for marketing or used to build a profile.
- Signup status and dates
- Whether you have confirmed or unsubscribed, when, and which version of the signup notice you saw — so we can honour your choices and show what you agreed to.
- Survey answers
- Only if you fill in the optional survey after confirming: a topic, a session length and, if you choose, one sentence about your goal. Used to decide what to build first. Your sentence is never sent to analytics.
- Answers typed into the sample lesson
- If you type an answer the scripted lesson cannot read, that answer is sent to Anthropic so its model can reply. We do not store it or link it to you; answers the script recognises never leave your device.
- Usage analytics
- Currently switched off: this site sends no analytics events and records no campaign or referrer information. If that changes, you will be asked first, nothing will be collected unless you agree, and this page will be updated.
- Abuse protection
- To stop automated signups we count requests per network address and per email address. Only a one-way hash is stored, never the address itself, and the counters are deleted once they expire.
- Delivery reports
- Our email provider tells us whether a message was delivered, bounced or marked as spam, so we stop writing to addresses that do not want or cannot receive our email.

How long we keep it
- Your email address and signup status are kept while you are on the early-access list. If you never confirm, you can ask us to delete the unconfirmed entry at any time.
- If you unsubscribe, we keep your address on a do-not-email list so that we never write to you again by mistake. Ask us and we will delete everything else about you.
- Survey answers are kept with your entry and deleted with it.
Your choices
- Unsubscribe from every email using the link at the bottom of any message we send.
- Ask for a copy of what we hold about you, or for it to be deleted, by writing to the address below.
