Version 0.1.0-pilot Effective August 2026 GDPR · UK GDPR · CCPA
The short version
  • No accounts, no advertising, no third-party trackers, no fingerprinting.
  • Everything you type into the symptom navigator stays on your device. There is no endpoint that receives it.
  • Analytics and research categories are off until you switch them on, and switching them off again costs one click.
  • We hold no health data about you, which means there is nothing about you for anyone to subpoena, breach, or sell.
  • You can erase every trace this site has written on your device from the button further down this page.

Who we are

AURORA is an open infrastructure project for neurosurgical disease, run by a distributed collective and currently in private pilot. For this website, the AURORA Collective is the data controller.

This notice covers this website only. It does not cover hospital deployments of AURORA software: in a federated install, patient data stays inside the institution and the institution is the controller. We never receive it.

What we collect

Almost nothing, and nothing that identifies you. There is no account system, no login, no advertising, no third-party trackers, no fingerprinting, and no data broker relationship of any kind.

Three things are worth naming explicitly:

  • Everything you type into the symptom navigator — symptoms, scores, notes, your symptom log — stays in your browser's local storage on your own device. It is never transmitted to us.
  • If you opt in to analytics, we record page-level counts with truncated IP addresses. We cannot reconstruct a person or a session history from them.
  • If you subscribe to the council newsletter, we store the email address you give us and nothing else.

Health information

Anything you enter about symptoms is health data — the most strongly protected category there is. We have designed this site so that we never hold it. That is a deliberate architectural choice, not a policy promise: there is no endpoint to send it to.

This also means we cannot recover it for you. If you clear your browser storage or use a different device, your answers and symptom log are gone. Print or export anything you want to keep.

Why we're allowed to

Strictly necessary cookies rely on our legitimate interest in serving a working, secure website. Everything else — preferences, analytics, research improvement, the newsletter — relies on your consent, which you give explicitly and can withdraw at any time without giving a reason and without losing access to anything.

Who we share with

No one. We do not sell, rent, or trade data, and we do not run advertising. We use no third-party analytics, no embedded social widgets, and no external font or script CDNs that could log you passively.

Two narrow exceptions, both named: our hosting provider processes server logs on our behalf under a data processing agreement, and our newsletter provider stores subscriber email addresses. Neither receives anything you enter into the symptom navigator, because it never leaves your device.

How long we keep things

Server logs are truncated and deleted within thirty days. Aggregate analytics counts are retained for thirteen months, then discarded. Newsletter addresses are kept until you unsubscribe. On-device data lives until you delete it — see the erase button below.

Children and families

Many of these conditions are diagnosed in infancy, so we expect parents and carers to be reading on a child's behalf. We do not knowingly collect anything from a child, and because the navigator stores everything locally, a child's information never reaches us even when they use it themselves.

If you are under 16 and want the newsletter, ask a parent or guardian to subscribe instead.

Where data goes

This site is hosted in the European Union. If any processor is located outside the EU or UK, transfers rely on Standard Contractual Clauses and we will name the processor here before it goes live.

Changes to this notice

We will note material changes at the top of this page with a date, and never quietly widen what we collect. Because this is a pilot document pending legal review, expect it to become more precise rather than more permissive.

Cookies, category by category

Everything except the strictly necessary category is off until you turn it on. Your choice is stored in a first-party cookie for twelve months and you can change it any time from the button at the bottom of any page.

Your rights

Under GDPR, UK GDPR and CCPA you have the rights below. Because this site holds almost nothing about you, most of them you can exercise yourself in one click — no request form, no waiting period.

Access

Nothing to request for on-device data — open the navigator and it's all in front of you. For newsletter data, email us.

Erasure

Use the erase button on this page for on-device data; it takes effect immediately. Unsubscribe links delete newsletter records.

Portability

The symptom log exports as CSV and the summary copies as plain text, both from the navigator.

Rectification

Edit any answer directly in the navigator's review step; there is no server copy that could drift out of date.

Withdraw consent

Reopen the cookie panel from any page and switch a category off. It applies from that moment onward.

Complain

Write to dpo@aurora.health, and to your national data protection authority if we haven't resolved it.

Erase everything, right now

This clears every AURORA key this site has written on this device: your cookie choice, guide-entry agreement, reading preferences, symptom navigator answers and symptom log. It cannot be undone, and there is nothing on our side to delete.

Nothing stored on this device
Cookies · federation-first by default

We keep essential cookies so the site works. Everything else — analytics on which guides help, and remembering where you left off in a guide — is off until you say yes. We never sell data, and nothing you read here is tied to a clinical record.
