Privacy Policy

Last updated June 18, 2026

SelfBuildOS is built for a single owner-builder managing a single build. We collect the minimum needed to run the Service, we don't sell your data, and you can export and delete it. This policy explains what we collect and why.

What we collect

  • Account info — your email, name, and password (stored hashed by our auth provider).
  • Build data — everything you enter: phases, tasks, budgets, materials, subs, appointments, plans, documents, logs, and draws.
  • Billing info — handled by Stripe; we store your subscription status, not your card.
  • Basic technical data — standard logs needed to operate and secure the Service.

How we use it

To provide the Service, process your subscription, send the emails and reminders you've enabled, and keep the product secure and working. We don't sell your data or use it for advertising.

Service providers

We rely on a small set of trusted processors to run the Service. Each handles only the data needed for its role:

  • SupabaseDatabase, authentication, and file storage
  • VercelApplication hosting
  • StripeSubscription billing and payments (we never see your card number)
  • ResendTransactional and reminder emails
  • GoogleOptional, only if you connect Google Calendar — two-way appointment sync
  • Open-MeteoWeather snapshots for daily-log entries (by coordinate and date)

Data retention & export

Your data is kept while your account is active. You can export it to CSV at any time. If you cancel or delete your account, your build data is retained for about 90 days as a safety window and then removed. You can request earlier deletion by email.

Security

Data is access-controlled per account (row-level security), encrypted in transit, and any third-party tokens — such as a connected Google Calendar — are encrypted at rest. No system is perfectly secure, but we keep the surface small by design.

Your choices

You can edit your profile, change notification preferences, disconnect Google Calendar, export your data, and delete your account from within the app. For anything else, just email us.

Changes & contact

We'll update this policy as the Service evolves; the "last updated" date above reflects the latest version. Questions or requests? Email ryan@selfbuildos.com.
