Your CAD, precisely.

Geometry analysis: local, not uploaded

Buildable's DFM checks, material recommender, and assembly interference detection run entirely in your browser via WebAssembly. When you upload an STL, 3MF, or STEP file, that file is parsed and analysed on your own machine. It is not transmitted to a Buildable server as part of the analysis.

What the AI features send

Three optional features, explaining results in plain English, planning an automatic fix, and the in-app chat, call a server-side function that talks to Anthropic's Claude API. What is sent is a small, bounded, structured summary: numbers and coordinates already computed in your browser (a wall thickness, an overlap volume, a count of flagged faces), plus any text you type into the chat or the part-description field. Raw mesh or CAD geometry is never sent. If you do not use these features, no CAD data or analysis result ever leaves your machine.

Hosting and basic logs

Like any website, standard web hosting infrastructure may log basic request metadata (IP address, timestamp, requested path) for operational and security purposes. This is standard hosting-provider behaviour, not Buildable-specific tracking, and it does not include your CAD file content. The site also loads its fonts from Google Fonts, a standard third-party request for the typeface files, on every page regardless of whether you use the app.

Accounts and local storage

Buildable does not currently require or offer account creation. There is no login, no stored user profile, and no cross-session history tied to an identity. Buildable does save a small "Projects" list, name, manufacturing process, status, and revision count, to this browser's local storage so you see your recent work again next time you visit. It never contains the CAD file itself, it is never sent to a server, and it is cleared if you clear this browser's site data.
