Trust
Radical transparency.
The most personal thing you will ever share is how your body is actually doing. It deserves the plainest promises you have ever read — no fine print, no hedging. Here is exactly what Atlas does with your health, in language anyone can follow.
You can delete everything, anytime.
The deal, in three lines.
The rest of this page just explains these in more detail. Nothing here walks them back.
Locked up tight
Every message, voice note, and photo you send is locked so no one else can read it — both while it sits with us and while it travels to and from your phone.
Never sold. Not ever.
We do not sell your data, and we never hand it to advertisers. No ad network, no data broker, no one buying a peek at your health. This is not a promise we can quietly walk back later.
Yours to erase
Ask us to delete your account and everything we have on you is gone — usually within seven days. One email, and we do not make you jump through hoops to do it.
We only collect what makes
the next conversation better.
Atlas is a daily health check-in. To be useful, it remembers what you tell it — your symptoms, what you have tried, what helps and what does not. That is the whole point, and it is the whole reason we collect anything at all.
What you tell us
Your first name, phone number, time zone, the conditions you choose to share, and every message you send. Voice notes are transcribed to text — we keep the transcript, not the audio.
What Atlas notices
The symptoms, medications, and everyday things you mention — kept in order from your own words, so Atlas can spot patterns you would never catch day to day.
What Atlas remembers
A long-term memory of what matters to you — your conditions, your routines, the people in your life — so a conversation months from now still feels like talking to someone who knows you.
You hold the controls.
Radical transparency is not much use without radical control. So all of this is yours, on request, at any time:
- See exactly what Atlas remembers about you — and delete any piece of it.
- Fix anything that is wrong.
- Ask for a copy of everything we have, to keep or take with you.
- Pause or snooze your check-ins whenever life gets loud.
- Reply STOP from your phone to stop the messages right away.
What deleting really means. When you ask us to delete your account, the delete button actually deletes — it does not just hide things. Your messages, voice notes, photos and documents, everything Atlas remembered, the notes on your symptoms, and the usage data tied to you all go, usually within seven days. The only things we hold onto are records the law requires us to keep, and anonymous, blended-together data that no longer points to you and that we had already mixed in before you asked.
Where your data goes — the whole list.
Atlas runs on a short, carefully chosen list of outside companies. Each one does a single job so Atlas can work, and none of them is an advertiser. We would rather show you the whole list than pretend there is no list.
Google Cloud
Runs the servers and storage that Atlas lives on.
Anthropic (Claude)
Makes Claude, the AI that Atlas talks with. They do not use your data to train their AI.
Google Vertex AI
The secure path we send messages through to reach the AI, and what turns your voice notes into text.
Firebase
Checks it is really you when you sign up with your phone number.
Linq & Twilio
Carry Atlas’s messages to your phone over iMessage, and by text if that is not available.
Google Document AI
Reads the text out of a lab result or photo you send in.
Before any data leaves our own systems — say, to help us fix a bug — we automatically strip out anything that could point to who you are. And yes: real people on our team sometimes read real conversations, because that is how we find bugs and make Atlas better. We would rather tell you that plainly than bury it on page nine.
You should never have to trade your privacy for better health. Atlas is built so you don't: you choose what to share, you can see all of it, and you can take it all back.
What the network shares —
and what it never does.
Atlas gets more useful as more people use it, because it can learn what tends to help people like you. That only works if sharing is safe — so we drew a hard line around it, and joining in is always your choice.
What the network can learn
Broad patterns with no names attached — like “people with these symptoms often felt better after trying X.” A pattern only shows up once enough people have shared it, so no one person can be picked out of the crowd.
What it never sees
Your name, your phone number, and the actual words of your conversations are never shared with other members and never sold. No one looking at the network can trace anything back to you. And if you opt out, none of your information goes in at all.
How Atlas makes money.
A fair question to ask a health company — so here is the honest answer, present and future.
Today
Atlas is an early research preview and does not make money from your data. We do not run ads and we do not sell data — not to advertisers, insurers, employers, or data brokers.
The plan
One day Atlas will charge for the product, and it may build a business on the broad, no-names-attached patterns the network turns up — never by selling data that points to you. If that ever happens, we will show you exactly how it works and how the value makes its way back to the people who made it possible. Health data has been quietly sold off for decades and patients got nothing. We are building the opposite.
The spirit, and the letter.
This page is the spirit of how we treat your data. The Privacy Policy is the letter of it. We wrote both to say the same thing — read whichever you trust more.
Read it, then decide.
That is the whole point of this page. When you are ready, Atlas is here.
