Consumer Health Data Policy

Effective 1 November 2026

This policy covers consumer health data under the Washington My Health My Data Act, Nevada SB 370 and the Connecticut Data Privacy Act. It sits alongside the Privacy Policy.

What we collect

Big Why keeps health details as memory only after you turn on Remember health-related details in Settings › Memory and AI, which asks for your consent on its own page. With it on, the assistant may remember things you mention about:

• mood, stress and energy;
• sleep;
• habits such as exercise, eating and screen time;
• alcohol, tobacco and other substances;
• your body and physical health.

Some of these may be inferred from what you say rather than stated; each remembered fact is marked “You said it” or “Inferred”. Separately, and whatever the setting, the written transcript and summary of a conversation keep what was said in it, which can include health details you mention. They are kept until you delete your account.

Where it comes from

Only from you, in your conversations with the assistant and what you write in the app.

Why we use it

Only to personalize your conversations, daily notes and weekly letters. Never for advertising, never sold, and never used to train AI models.

Who receives it

• OpenAI, our AI provider, which processes it so the assistant can work, keeps it for up to 30 days for abuse monitoring, and does not train on it.
• Supabase, which stores it in our database.

We share it with no one else, we do not sell it, and we do not use geofences around places where health services are provided.

Your rights

• Withdraw consent at any time by turning the setting off. The health details remembered so far are deleted at once.
• Access what we hold, and the list of companies that receive it (above): every remembered fact is on Who I am, and Settings › Your data › Export gives you all of it.
• Delete it: forget any fact on Who I am, turn the setting off, or delete your account. We delete within 45 days of a request, and usually at once.

Email support@abigwhy.com to use any of these rights. We answer within 45 days.

Appeals

If we decline a request, write to support@abigwhy.com with “Appeal” in the subject. We answer within 45 days and explain our decision. If you are not satisfied, you can complain to your state’s attorney general: Washington, Nevada or Connecticut.
