The Choice-Point Month pilot: how I handle your answers

Last updated 8 November 2026

I'm Chernyang Lee, and I run Understory. Questions about your data: hello@mornsolar.com.

What I collect

Your first name and email, so I can write to you, and your participant code. If you ask to take part through the pilot page, the sign-up form also has an optional box for your last name.
Your form answers: whether you fit the pilot, how well you know me, what you've tried, how work reaches your phone, your three scores, how far you got, your views on some wording and price, your open answers, and your quote and permission choice.
Anything you email me, including a reply to an optional question I'll send in January 2027.

I don't ask about your health, but one question asks whether any part of the workbook left you feeling worse, so you may mention it. If you mention your health, or other people, in an open answer, I'll hold that too, so please leave out anything you'd rather I didn't. The forms don't collect your email address.

Your answers carry a code rather than your name, but they aren't anonymous to me, because I keep the list that matches the two.

Why

To see whether people finish the workbook, what they report changing, what gets in the way, and which wording is clear. This helps me improve the workbook and decide how to describe and sell it. I don't sell your data.

Who sees it

Your scores are only ever shared as group totals, described as self-reported. Your quote is only used as you allow in the after form.

Where it's kept

Form answers: Google Forms and a private Google Sheet in my own account, under your code.
Your name, email and code, with quote permissions, and what you send through the sign-up form (which is hosted by Airtable): a separate Airtable base in my account, which only I can open.
Emails: my hello@mornsolar.com mailbox, with Purelymail.
I use Claude, an AI assistant made by Anthropic, to help me summarise and analyse form answers, so anything you wrote may be processed by it. I don't give it the list of names. I read and send every email myself.

Google, Anthropic, Airtable and Purelymail are based in the United States.

The optional online check-in is separate, and is covered by the site's privacy page.

How long

I treat the pilot as running until 31 January 2027, after the optional January question. I keep your data for up to 12 months after that, so until 31 January 2028 at the latest. Then I delete it, or keep only anonymous totals.

If you ask to take part and I can't take you on, I'll tell you and delete your sign-up details within 7 days.

If I publish your words with your permission, I keep them and the permission record while they're in use, and for up to 12 months after they come down. If you withdraw, I keep a one-line note under your code that you did, so that I don't use your words again.

How to withdraw

You can stop doing the workbook at any time without telling me. To stop my emails, or to see, correct or delete what I hold about you, email hello@mornsolar.com. No reason needed. I'll do it within 7 days, and you keep the workbook. Copies held in my providers' backups, such as Google's and Airtable's, can take longer to disappear.

Two limits: group totals that are already published can't be recalculated, though nobody can be identified from them, and I can't recall copies of your words that other people have already shared.

You can also complain to the Information Commissioner's Office: ico.org.uk.

This pilot is for adults aged 18 and over.
