We verify facts. We don’t sell data.

ADUOS is an address-first ADU feasibility tool. To work, we need to know the address you’re asking about. If you want to save or come back to a case, we also need your email.

We do not sell, lease, or broker your information. We do not run third-party advertising trackers. We do not share your address with providers unless you explicitly opt in after paid review.

• The address you enter. Required to run the parcel lookup and show the feasibility answer.
• Your email (optional). Only if you choose to save your case or receive a magic-link sign-in.
• Anonymous usage events. Address submitted, case opened, evidence drawer opened. No personally identifying attributes attached.
• Payment data (only if you buy). Handled by Stripe; we never see your card number.

• Run your address against public parcel and zoning data.
• Generate your case and save it under your account if you signed in.
• Improve ADUOS based on aggregate usage patterns (never tied back to an individual email or address).
• If you explicitly request provider help after paid review, we may share only the case details needed for that request.

• We do not sell, lease, or otherwise monetize your contact information.
• We do not run third-party advertising pixels, retargeting scripts, or behavioral tracking.
• We do not send you newsletters you didn’t ask for.
• We do not share your address with builders or plumbers unless you explicitly request that handoff.

If you have an account, your case stays in your account until you delete it or ask us to delete it.

If you used ADUOS without an account, the case may not be available permanently. Sign in to keep it tied to your account.

Aggregate usage data is retained indefinitely in anonymized form, because we use it to understand what homeowners actually need.

Under the California Consumer Privacy Act (CCPA) and similar regulations, you have the right to know what data we hold about you, correct it, export it, or delete it. To exercise any of these rights, email hello@aduos.co from the email tied to your account. We’ll respond within 30 days.

Data at rest is encrypted via Supabase’s managed infrastructure. Data in transit is TLS 1.3. We use strict Content Security Policy, HSTS, and SameSite cookie rules. If we ever discover a breach, we’ll notify affected users within 72 hours.

If we change this policy materially, we’ll note the change here and email users with accounts. The “last updated” date at the top reflects the most recent change.

Privacy questions go to hello@aduos.co. We read every one.
