Your data

Your CAD stays in your browser

AddPly is a browser application with no account and no server-side storage of your work. The plainest version: the STEP file you choose is read in your own browser, and the projects you save are written to your own browser’s storage.

What happens to a file you open

• The STEP file is read in the page and measured by OpenCascade running in a Web Worker in your browser. It is not sent anywhere.
• The application never reads a file you did not choose, and never writes to one. Exporting a project uses your browser’s own download, to a location you control.

What is stored, and where

• Saved projects go into IndexedDB in this browser, for this site address only. They contain your design and the exact CAD geometry it was authored on.
• A small pointer records which project you had open, so it can be offered back to you on your next visit.
• Nothing is synced. Another browser, another computer, a private window, or a different site address will not have your projects. Browser storage belongs to an origin, so a project saved at one address is not visible at another — moving work across addresses is what the exported project file is for.
• Clearing this site’s data deletes them. Export a project file to keep a copy that survives that.

What is not collected

• No account, no sign-in, no email address.
• No analytics and no advertising or tracking cookies.
• No upload of your CAD geometry, your project files or their names.

Operational data

Serving the application means a web server sees the ordinary requests any website sees — the pages and assets your browser fetches, and the network address it fetches them from. That is infrastructure, not product telemetry, and it never includes your CAD geometry, project payloads or project names.

The exact hosting arrangement is not settled, so the retention and the operator of those logs are not described here yet. This section will state both, specifically, before the product is published — and if it cannot, it will say so rather than approximate.

Getting your data out

Export project… writes a portable .cad-laminate.json file containing the whole design and its exact geometry. It is readable, it is yours, and it is the format the application itself reads back. There is nothing to request from anyone.

Deleting your data

Delete a project from the library in the workbench, or clear this site’s data in your browser to remove all of them at once. Neither touches files you exported.
