# STL Repair — full site context

## Product

STL Repair helps 3D printing users inspect STL files before printing. It focuses on fast STL checks, issue explanations, print-readiness scoring, conservative safe repair, and paid export of repaired files or reports.

## Core workflow

1. Upload an STL file.
2. Parse binary or ASCII STL geometry.
3. Analyze mesh health and print-readiness signals.
4. Explain detected issues in plain language.
5. Apply only low-risk repair actions when available.
6. Gate repaired STL downloads and repair reports behind the configured plan.

## Repair boundary

STL Repair V1 is not a CAD system, slicer, or guaranteed watertight reconstruction engine. Safe repair is limited to common low-risk operations such as removing degenerate faces, removing duplicate faces, and recalculating facet normals. Open boundaries, holes, self-intersections, and complex non-manifold geometry may be reported for review instead of forcibly repaired.

## Data and privacy

Uploaded STL files and generated artifacts are private user data. Storage-backed files are served through same-origin access checks. Private file URLs, dashboard pages, account pages, API routes, and storage routes should not be indexed. Users can delete saved files, and expired or deleted STL records should no longer be downloadable.

## Crawl policy

Search engines and AI crawlers may index public product, documentation, blog, and SEO pages. They should not crawl private dashboards, auth pages, account settings, APIs, or storage artifact URLs.
