Privacy
Last updated 27 October 2026
Know Thyself is a place for work that is yours: your biography, your dreams, your observations, the things you make. This page says plainly what we keep, where it lives, who can see it, and how to take it back. It is written to be read, not scrolled past.
Who we are
Know Thyself is made by Tree Media, United States. You can reach us at hello@knowthyselfwork.world.
What we keep
- Your email address, used to sign you in. We send a link to it; there is no password.
- What you write and set in the app: your answers in the intake interview (including your name, date, time and place of birth if you give them), your notes, observations, Day & Night entries, task ticks, book notes and slider positions.
- What you upload: the photo for your circle and the images and sound recordings you add to Creations.
- Purchase record: if you buy the full work, the date, amount and a Stripe reference. We never see or store your card number.
- Share links you create for a montage, so we can serve them and so you can revoke them.
That is the whole list. We do not run analytics, advertising trackers or third-party scripts on the site, and we do not buy or sell data about you.
Where it lives
Your data is stored on Cloudflare's infrastructure in a database and file store that belong only to Know Thyself. It is encrypted in transit and at rest in the ordinary way. It is also kept in your own browser so the app works offline and loads instantly; signing out does not clear that copy, so on a shared computer use a private window.
We can, in principle, read what is stored, because that is what lets us sync it between your devices and recover it for you. We do not read it unless you ask us to help with your account, and no one else is given access.
Who else touches it
- Cloudflare hosts the site and stores the data.
- Resend delivers the sign-in emails. It sees your email address and nothing else.
- Stripe handles payment. Your card details go to Stripe directly and never pass through us.
- Bookshop.org and the Rudolf Steiner Buchhandlung receive you if you follow a book link. Bookshop links carry an affiliate code, which means a small share of a purchase supports Know Thyself at no cost to you. They see only that you arrived from here.
Sharing a montage
A montage is private. If you create a share link, anyone who has that link can read that one montage — the text, images and recordings in it, and your first name if you gave one — until you revoke the link in the app. Nothing else of yours is visible through it.
Cookies
One cookie, kt_session, keeps you signed in for ninety days. There are no others.
How long we keep it
For as long as you have an account. Sign-in links expire after twenty minutes and are deleted. Purchase records are kept as long as the law requires us to keep accounts.
Taking it back
You can export every montage as a PDF from the app. To delete your account and everything in it — writing, uploads, purchase record, share links — email hello@knowthyselfwork.world from the address you signed in with and we will do it within a few days and confirm. Deletion is complete and cannot be undone, so download what you want to keep first. A delete button inside the app is coming.
If you are in the European Economic Area, the United Kingdom, California or another place with its own privacy law, the rights those laws give you — to access, correct, export, delete or object — are honoured on the same email address, without charge.
Children
Know Thyself is written for adults and we do not knowingly keep data about anyone under sixteen. If you believe a child has made an account, write to us and we will remove it.
Changes
If this page changes in a way that matters, the date at the top changes and signed-in users are told in the app. We will not quietly widen what we collect.
