What weichseltree.com and the Mind Palace keep about you, for how long, and who sees it. Last changed 10 October 2026.
Who is responsible
Weichseltree OÜ, Sepapaja tn 6, 15551 Tallinn, Estonia, registry code 17482992, managed by Manuel Weichselbaum. E-mail: weichselbaum.manuel@gmail.com. The full legal notice is the Impressum.
The short version
No accounts, no analytics, no advertising. If you walk into the Mind Palace, other people in the same room see the name you pick, where you stand and what you say. We keep as little as makes that work, and delete it on a schedule.
What is kept, and for how long
| What | Who sees it | How long |
|---|---|---|
| The name you choose, and the room you are in | People in the same room | 30 days after your last visit |
| Where you stand in the room | People in the same room | Only while you are there |
| What you say in chat | People in the same room | 24 hours |
| Your voice, while you hold the talk button | Nobody here: it passes through our site to Deepgram to be written down, and the words become a chat line | We keep no audio. The words are kept as chat, 24 hours |
| A report someone makes about you: their reason and your last five lines of chat in that room | The host only | 90 days |
| A ban, if you get one | The host only | Until it ends |
| A scrambled code for your pass or your network, only if it is shut out of talking for misuse | The host only | Until it is lifted |
| A scrambled code for your network (see below) | Nobody reads it; the world uses it to count and to ban | 30 days after your last visit |
Nobody outside a room can read who is in it or what is said there. The host, Weichseltree OÜ, can see everything in the table above.
Your identity, without an account
When you enter the Mind Palace, your browser asks our token service (at /auth on this site) for a token. The service may first run Cloudflare's human check, Turnstile, which usually shows nothing. The token names a random identity for you. Your browser keeps it for 30 days and renews it, so you are the same visitor next time. Clearing this site's data in your browser makes you a new visitor.
The token service sees your IP address, as every website does. It does not store it. It turns your network (your IPv4 address, or the first half of an IPv6 address) into a scrambled code using a secret key that only the service holds. That code goes into the token. It lets the world notice that eight visitors came from one network, or keep a banned network out, without ever learning the address.
Speaking
You can talk instead of type. Nothing is heard until you hold the talk button, or press the thumbstick in a headset, and your browser asks your permission the first time. While you hold it, your browser sends the sound to our site, which passes it on to Deepgram as it arrives; Deepgram turns it into text, and the text is said in the room as an ordinary chat line, under your name. Our site does not record or keep the audio. To start, your browser gets a pass from our site that works for 30 seconds and opens nothing but connections to the transcriber. If you never press the button, no sound leaves your device.
What your browser stores
We set no cookies. The Mind Palace keeps up to four entries in your browser's local storage: orchard.grove.pass (the token), orchard.grove.name (the name you picked), orchard.grove.guide-seen (whether you have dismissed the first-visit guide) and, from older visits, orchard.grove.token. The guide preference stays in your browser until you clear this site's data. Cloudflare may set cookies of its own that the human check needs.
Who else handles data
- Cloudflare serves this site, the media and the token service, runs the human check, and carries the sound of the talk button on its way to Deepgram. Cloudflare's privacy policy.
- Deepgram (Deepgram, Inc., USA) turns what you say into text, only while you hold the talk button. The audio passes through our site on Cloudflare on its way to Deepgram; we do not record or keep it. Every request that carries your voice opts out of Deepgram's model improvement programme, so Deepgram keeps the audio only as long as it takes to process it and does not use it to train its models. Deepgram's privacy policy.
- Clockwork Labs hosts the world's database (SpacetimeDB). Names, rooms, positions, chat, reports and bans live there. Their privacy policy.
Your rights
You can ask what is kept about you, and ask for it to be deleted, at any time, by e-mail to the address above. Because there are no accounts, tell us the name you used and roughly when you visited. You may also complain to a data protection authority: in Estonia, where the company sits, the Andmekaitse Inspektsioon; in Austria the Datenschutzbehörde.
