Privacy

Your memory is the producteverybody else is selling.

Every other assistant keeps what it learns about you on a company's servers, because that is the asset. Maison keeps it in a database on your own disk, where you can read it, copy it, back it up or delete it without asking anyone, including us.

No training on your data Zero conversations on our servers by default Nothing exposed to the internet
What you are actually promised

Four things, stated plainly enough to hold us to.

A privacy policy is a document that can be rewritten. These are properties of where the software runs, which is a harder thing to quietly change.

01

Local by default

Your conversations, files and memory stay on your machine. Keeping memory on your own disk is the default and it costs nothing, because six months of the heaviest use we have measured came to 1.2 GB. Memory is small. That is why we would rather you kept it.

02

No training on your data

Not now, not quietly, not later. Nothing you say to your Maison becomes material for a model somebody else uses, and there is no version of the arrangement where that changes because a term sheet did.

03

You can read your own memory

It is plain files in a database on your drive, not a black box. Everything it has come to know about you is something you can open and look at, which is the only real test of whether a claim like this one is true.

04

If you walk away, you take it

Cancel, unplug, or leave entirely and the memory is still there and still yours. Nobody can read it remotely, and that includes us. It is not held hostage to a subscription.

Where each piece sits

The part that leaves, and the parts that do not.

Nobody should have to take a diagram on faith. This is the whole of it: what stays on the machine in front of you, and the one thing that goes out and where it goes.

Stays on your disk

Everything it knows

  • The memory database, and every conversation in it
  • Your files, and anything it has written for you
  • The speech models that hear you and answer you
  • The search that runs across your own memory

These keep working with the network off, which is the simplest proof that they are not going anywhere.

Goes out, to your own account

The reasoning

  • The hard thinking runs through your own Claude account
  • Billed to you by Anthropic, under your terms rather than ours
  • We are not in the middle of it and we do not mark it up
  • Your relationship with them, on their published terms

We would rather say this out loud than let local do quiet work in a sentence it cannot support.

There is no public address. The assistant is reachable from your phone over your own private network, and nothing is exposed to the internet.

The one exception, and it is yours to make

Hosted memory exists, costs extra, and is off by default.

If you would rather not keep the memory yourself, we will hold it in a database of your own, kept separate from every other person's. It costs extra, because hosting costs us money and we would rather charge for it honestly than pretend it is free. You choose during setup, and the default is your machine.

Included, recommended

On your machine

Everything it knows sits in a database on your own drive. If you cancel, unplug or walk away entirely, the memory is still there and it is still yours.

Additional monthly fee

Hosted by us

A database of your own, kept separate from everyone else's. Chosen deliberately by you, never the quiet default, and never the thing that happens if you do not read a screen.

Why you can believe it next year

A promise is only as good as the people keeping it.

Every company that ended up somewhere ugly started out meaning well. Good intentions are not a structure, and they do not survive a change of ownership. So this one is built with the structure first.

The company

A public benefit corporation

Maison Collective is a Delaware public benefit corporation with its purpose written into the charter, including that the capability and what it learns go to the people using it.

The safeguard

Twelve trustees who own nothing

An independent trust holds stock carrying no economics and exactly one power: the power to say no to a sale, a change of purpose, or dropping the public benefit status.

The text

The values, published in full

We publish what these systems act under rather than keep it proprietary, in full and in the form the software actually reads. A value nobody outside the company can read is not a commitment, it is a mood.

The architecture of a devoted guide and the architecture of a manipulation engine are identical. The only difference is who it answers to. Read the constitution.

Questions

Questions about privacy.

Is Maison actually private?

Your conversations, files and memory stay on your machine by default, and by default none of your conversations are stored on our servers. The memory is a database on your own disk that nobody can read remotely, and that includes us.

Do you train on my data?

No. Not now, not quietly, not later. Nothing you say to your Maison becomes material for a model somebody else uses.

What actually leaves my machine?

The reasoning. It runs through your own Claude account, which you sign in to once during setup, and it bills to you by Anthropic under your terms rather than ours. We are not in the middle of it and we do not mark it up. Everything else stays on your disk.

Can anyone reach my Maison from the internet?

No. It is reachable from your phone over your own private network only. There is no public address and nothing is exposed to the internet, so there is no door to knock on.

What happens to my data if I cancel?

You keep it. Cancel, unplug or walk away entirely and the memory is still on your disk and still yours. It is not held hostage to a subscription.

Can I keep my memory somewhere other than my own machine?

If you would rather not keep it yourself we will hold it in a database of your own, kept separate from every other person's. It costs an additional monthly fee, because hosting costs us money and we would rather charge for it honestly than pretend it is free. Your own machine is the default and it is included.

Ask us the hard version of the question.

If there is a part of this you do not believe, write and say which part. You will get a straight answer from somebody who built it.
