Privacy Policy
Last updated July 8, 2026
Dynaco Passport Home is a product of Dynaco Testing LLC ("Dynaco," "we," "us"). This policy explains what information the app collects, how we use it, and the choices you have. We built Passport Home to help you track and care for your home — we do not sell your personal information.
Information you provide
•
Account details — your name, email address, and (optionally) phone number. Passwords are handled by our authentication provider and stored only as a secure hash.
•
Home information — the address and details of the home(s) you track: property characteristics, systems and appliances, test results, service and maintenance logs, and any notes you add.
•
Documents you upload — photos and files you add to your vault, such as receipts, warranties, inspection or test reports, and equipment data plates.
Information created automatically
•
Derived data — your Passport Score and related assessments, and an approximate latitude/longitude geocoded from your home address (used to check weather for your location).
•
Device token — if you turn on push notifications, a push token for your device so we can deliver alerts.
How we use your information
We use the information above only to operate and improve the app: to
•
maintain your account and store your home profile and documents;
•
calculate your Passport Score and generate your reports;
•
send the alerts you enable — severe-weather warnings for your area, appliance safety recalls, and reminders for due maintenance and expiring warranties;
•
answer questions about your home and read your uploaded documents using AI features; and
•
respond to your support requests.
Service providers we share data with
We share the minimum data necessary with providers that operate parts of the service on our behalf. They may only use it to provide their service to us:
•
Supabase — hosting, authentication, database, and encrypted file storage for your account and home data.
•
Anthropic — powers the AI features. When you ask a question about your home or have a document read, the relevant home context or document is sent to Anthropic to generate the response. It is not used to train their models.
•
RentCast — when you look up a property's value or public record, the address is sent to retrieve that information.
•
U.S. Census Bureau geocoder — to check weather for your home, your address is sent to convert it into approximate map coordinates.
•
U.S. National Weather Service & U.S. Consumer Product Safety Commission — public data sources used to match weather alerts to your location and recalls to your appliances.
•
Amazon Web Services (SES) — delivers the email notifications you enable (via our dynacopassport.com service); it receives your email address and the content of the alert.
•
Expo — delivers push notifications to your device.
We may also disclose information if required by law, or to protect the rights, safety, and security of our users and the service. We do not sell your personal information or share it for advertising.
Data security
Data is encrypted in transit (TLS) and at rest (AES-256) by our infrastructure provider. Your home data is protected by per-user access rules so that only your account can read it, and your uploaded documents are kept in a private storage bucket accessible only through short-lived, signed links.
Your choices and rights
•
Access and correct — you can view and edit your account and home information at any time in the app.
•
Notifications — you can turn email and push notifications on or off in Account settings.
•
Delete your account — you can permanently delete your account and all associated data from Account settings ("Delete account"). This removes your homes, documents, and account record. You may also email us to request deletion or a copy of your data.
Data retention
We keep your information for as long as your account is active. When you delete your account, your account record, home data, and documents are removed.
Children
Passport Home is intended for homeowners and is not directed to children. We do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this policy from time to time. When we do, we will revise the "Last updated" date above.
