Privacy policy

Last updated 21 September 2026

WWW.DIRECTORY.COM.AU PTY LTD (ABN 68 090 816 461) ("we") operates Build Design Solutions Cost at builddesign.solutions/cost. This policy explains what we collect and how it is used, in line with the Australian Privacy Principles.

What we collect

  • Account details: name, company, email address and a hashed password.
  • Estimate data: project names, addresses, settings, uploaded documents (drawings, reports, images), the pages rendered from them, extracted text, quantities and prices, and the commentary generated for you.
  • Support messages: the name, email and message you send through the support form, plus the connection IP address for abuse prevention.
  • Payments: card payments are taken by Stripe on its own pages; we receive the payment status, amount, the email you gave Stripe and a receipt link, never your card number.
  • Technical logs: server logs and daily page-view counts without personal identifiers. We do not use advertising trackers or third-party analytics.

How we use it

  • To produce your estimates, run your account and answer support.
  • Document pages and extracted text are sent to Anthropic's API (Claude) to classify, read and measure them; that processing happens on Anthropic's infrastructure, which is outside Australia. Under Anthropic's commercial API terms, customer content is not used to train models. No other third party receives your documents.
  • Transactional email (payment received, estimate ready, password reset) is sent through our own mail relay.
  • We do not sell personal information and do not send marketing without consent.

Storage and security

Your documents and estimates are stored on our server in the Sydney AWS region, in a location the web server cannot serve directly, with access limited to the operator. Passwords are hashed with bcrypt, sessions are cookie-based and HTTPS-only. Share links expose a read-only estimate to anyone holding the link; you control whether one exists.

Retention and deletion

Estimates and documents stay until you delete them (Settings, Delete estimate) or close your account. Deleting an estimate removes its documents, rendered pages, lines and logs. Server backups roll over within 14 days. To delete your account, use the support form from your registered email.

Access and questions

You can view and export your data from the app at any time. For access, correction or complaints, contact us through the support form. If you are not satisfied with our response you may contact the Office of the Australian Information Commissioner.
