What we hold, and what we never see.
Your brain's contents live on your server, not with us.
We hold only what you send us to arrange and run it.
Who is responsible
This site and the service are operated by hbar, 400 Rella Blvd, Ste 207-632, Montebello, NY 10901, United States. Write to hello@hbar.systems about anything on this page.
What we hold
- What you send us by email or through the form on this site: your name, your address, and what you write. The form passes it straight to our mailbox; this site keeps no copy.
- When we set up a brain for you: the setup record we write with you, and the name of your server.
- When you pay: the amount, the date, and the payment details your bank or payment service shares with us.
We use these only to answer you, to set up and run your brain, and to keep the records the law requires.
We do not sell them, and we do not use them for advertising.
This website
This site runs no analytics and sets no cookies.
Our web host keeps standard request logs (address, time, page requested) for operating and protecting the site.
Your brain
Your brain runs on its own server in a Hetzner data centre in the European Union (Finland or Germany). Your chats, documents, memory and keys are stored there.
The brain sends no telemetry and no copies of its contents to us.
When you use a model provider such as Anthropic or OpenAI, your brain sends your prompts to that provider under your own account and their terms. A local model sends nothing out.
We can reach the server to run updates and backups and to help when you ask. We do not read your contents. Security lists exactly what we can reach and how you close each door yourself.
Services we rely on
- Hetzner Online (Germany): the servers brains run on.
- Cloudflare: the names under brainfoundry.ai.
- Vercel: hosting for this website.
- Namecheap Private Email: our mailbox.
How long we keep it
Correspondence: for as long as we work together, and up to two years after, unless you ask us to delete it sooner.
Payment records: for as long as tax law requires.
Your brain: until the service ends. You receive your export first; then the server and its disks are deleted.
Your rights
You can ask to see, correct, export or delete what we hold about you. Write to hello@hbar.systems and we answer within 30 days.
If you live in the EU or the UK, you may also complain to your data protection authority.
Children
The service is not meant for anyone under 16.
