Privacy & Disclaimer

Privacy

DatumSpot is built to need nothing from you. There are no accounts and no sign-in — every calculator and reference works without giving us any personal information.

• Your saved items stay in your browser. The Collect board is stored only in your browser's local storage. It is never uploaded — there is no server that could receive or store it, and we cannot see it. Clearing your browser data removes it.
• No tracking. No advertising networks, no cross-site trackers, no fingerprinting, and no cookies used to identify you.
• Analytics. We use Cloudflare Web Analytics to count page views in aggregate so we know which tools are useful. It is privacy-first: cookieless, collects no personal data, and does not track you across other sites.
• Outbound links. "Further learning" links, cited sources, and links you save point to third-party sites. Once you leave, those sites' own privacy policies apply.

Because we collect no personal data, there is nothing to export or delete on request — clearing your own browser storage is fully in your control.

Disclaimer

• Verify code and standard numbers. Values drawn from codes and standards (e.g. the 2010 ADA Standards, the IRC, ASCE 7) are cited to their sources, but you must confirm them against your Authority Having Jurisdiction (AHJ) and the adopted code edition. State codes, local amendments, and rules for alterations to existing buildings differ.
• Rules of thumb are preliminary only. Tools such as the beam-span depth guide are for rough, early sizing. They are not span tables and not structural design, and they do not replace analysis by a qualified professional.
• Have critical work reviewed. Always check important numbers against the primary source and have work stamped or reviewed by a licensed professional where the law requires it.
• Provided "as is". The site is offered without warranty of any kind. You use it at your own risk; we are not liable for decisions made from its output.

DatumSpot is an independent project, maintained on a best-effort basis.
