The only thing kept is your email, if you give it

They run inside your browser. The portfolio you build, the starting amount and the dates you choose are never sent anywhere.

"Copy a link to this portfolio" puts the portfolio into the link itself. Whoever you send that link to sees the same sleeves. Nothing is stored on a server.

"Save this portfolio" keeps it in your own browser, on the device you are using, so it is there when you come back. It is not sent anywhere, and there is no account. Deleting it in the tool, or clearing your browser's site data, removes it.

If you ask for rule updates or join the kit waiting list, your email address is stored by MailerLite, the email service that keeps the two lists and sends the emails. It is used for those emails and nothing else. It is never sold or shared.

Like most email services, MailerLite also records when and from which internet address you signed up and confirmed, and it can tell whether an email was opened or a link in it was pressed.

You confirm your address by pressing a link in the first email. Every email has an unsubscribe link, and unsubscribing removes you from that list. To have your address deleted completely, write to david@hindscope.com.

The tool has a box for telling me what is missing or confusing. What you write, the first name if you give one, and whether you allow it to be quoted are stored in a Google sheet that only I can open. No email address is asked for, so I cannot reply, and a note cannot be traced back to you unless you put your details in it. Please do not.

A note is quoted on the site only if you ticked the box that allows it.

Visits are counted with Cloudflare Web Analytics, which uses no cookies and does not follow you from site to site. Its small counting script is the one thing loaded from outside this site. The pages are served by Cloudflare, which, like any web host, sees the internet address of your device in order to deliver the page.

If you close the reminder bar on a phone, your browser remembers that on your own device so the bar stays closed. Apart from portfolios you choose to save, that is the only thing the site keeps there.
