Privacy Policy

Existential Atlas is built to help people explore life's biggest questions. We try to collect as little as possible, and we never sell your data. This page explains, plainly, what we collect and why.

What we collect

• Questions you ask. Stored to generate answers, cache them, and understand what people are exploring. Questions that return no answer are logged so we can improve coverage.
• Your preferences. If you set up a profile (age range, perspectives, traditions, reading style), it's saved on your device. If you sign in, it's also saved to your account so it follows you across devices.
• Account information. If you sign in with Google or Apple, we receive your name and email address to identify your account. We never receive your password.
• Feedback. Anything you send through the feedback form, plus an email address only if you choose to provide one.
• Limited technical data. Your IP address is used briefly, in memory, to enforce daily usage limits and prevent abuse. It is not stored as a profile of you.

How your question is processed

To build a response, the text of your question and relevant passages from our library are sent to Anthropic (the AI service that writes the synthesis). Please don't include sensitive personal information in your questions.

Service providers

We rely on a few trusted services to operate: Supabase (database and sign-in), Anthropic (AI synthesis), Vercel (hosting), and Google / Apple (sign-in, only if you choose it). They process data on our behalf; we do not sell data to anyone.

Your choices

• Use the app without an account — your profile simply stays on your device.
• Reset your local preferences any time from the profile badge.
• If you have an account, you can delete it — and the profile stored with it — from your account settings. You can also reach us through the feedback page to request deletion.

Sensitive topics

Existential Atlas explores death, suffering, and meaning. It is not therapy or medical advice, and it is not a crisis service. If you are in crisis, please contact a local emergency number or, in the US, call or text 988 (the Suicide & Crisis Lifeline).

Children

The app is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children under 13.

Rights holders

Our library includes passages from published texts and from public interviews on YouTube. Every passage is attributed and links back to its source. If you hold rights in something we have indexed and would like it removed, tell us which channel, video, or text it is through our contact page and we will take it out of the corpus.

Contact

Questions about privacy, or a request to delete your data, can be sent through our feedback page. Anything that needs a reply from us can go through the contact page.

We may update this policy as the platform grows; we'll revise the date above when we do.
