Laydown Plan

Security

Site plans for stations, airports, and hospitals can be sensitive. Here is exactly how we protect them, and what we don't claim.

How your data is protected

  • Every request is checked against your workspace. Asking for another workspace's records returns “not found.”
  • Roles (owner, admin, coordinator, contributor, viewer) are enforced on the server, not just hidden in the interface.
  • Who drew, approved, or resolved something always comes from the signed-in account and can't be changed by the browser.
  • Uploaded plans are stored privately and served only through short-lived signed links.
  • Share links use random 32-byte tokens stored as a hash. They can be limited to chosen levels, set to expire, revoked at any time, and are hidden from search engines.
  • Every change is recorded in an audit log with before and after values.
  • Sign-in uses one-time email links. We don't store passwords.

What we don't claim

We're not SOC 2 audited and we don't offer single sign-on today. If you need either, tell us, so we know how many people are asking.
