Drawings and results

The drawing you upload and the result file are deleted automatically 7 days after the conversion finishes (or fails); the sweep runs hourly. Rebar take-off data is deleted after the period stated on that page.
If a conversion fails we keep the drawing for at most 7 days so a technician can check and re-run it, then delete it. Errors you can fix yourself (wrong coordinate system, empty drawing) are also kept 7 days at most.
The download link is a long random code and needs no account. Anyone holding it can download for 7 days, so do not post it publicly.
The drawing and result of a successful conversion may be opened by the operator for quality checks and support (see "Copy for the operator"); otherwise we do not look at your drawing other than converting it, except to investigate a failed conversion.

For every successful conversion the service operator receives an e-mail with the file types, size range, run time, the coordinate system used and two links: the drawing you uploaded and the result file. The e-mail contains neither your e-mail address nor your IP address.
The operator may open these files to check conversion quality and to support users. The links are operator-only, signed, expire after 7 days and open exactly one file of that one conversion; the drawing and the result are still deleted after 7 days as stated above.

Used only to send the download link. Once the message is sent, the address is removed from the job record.
If a conversion fails the address stays with the drawing (7 days at most) so we can write back, and it is included in the internal alert e-mail to our support team (with the file name, options and error).
E-mails are sent through a mail delivery provider (Resend). We do not use your address for marketing.

The web server logs only a masked IP address (IPv4 last 8 bits removed, IPv6 first 48 bits kept), no cookies, no URL query strings; the code in download links is masked. This log is kept 90 days at most.
The job record does not store the IP address, only a hash that changes every day, used to limit concurrent runs and for statistics. The application log holds only the masked IP and no e-mail; the error text of a failed conversion may mention the file name. Logs are rotated (3 x 10 MB at most) and the system keeps them 14 days at most.
We use Cloudflare for delivery and cookieless traffic measurement (Cloudflare Web Analytics). Cloudflare sees the full IP address under its own policy.

When you choose a DWG/DXF file it is read once on the converter to suggest a coordinate system, then deleted at once. The suggestion (a few sample coordinates and a simplified outline of the drawing) is kept at most 1 hour under a random code, without file name, e-mail or IP address.
Map previews load tiles from OpenStreetMap (tile.openstreetmap.org). Your browser fetches them directly, so OpenStreetMap sees your IP address and the area you view; the drawing file is not sent to them.

When a conversion finishes, the result page (and the e-mail, if you left an address) shows a quick-look image of the drawing you uploaded and of the result. They are made on our server, kept in the same folder as the drawing and deleted with it after 7 days. Images in the e-mail are attached to the e-mail itself and are not loaded from any web page.
For KML, KMZ and Shapefile results the result image draws the converted shapes on a base map (road, or satellite when available). Our server (not your browser) fetches a few map tiles of that area from OpenStreetMap or MapTiler; the provider sees our server's address and the tiles of the project area, not your file, file name or e-mail address. Map tiles are cached on the server for 7 days.

We keep counts of conversions, file type, size, run time and error class, without file names, e-mails or IP addresses.
