File confidentiality
CADProps treats uploaded CAD files and model data as confidential. We use them to provide the requested service, investigate processing errors and respond to support requests. Original CAD files are not published or sent to external CAD processing services. Files travel to our servers over HTTPS (TLS 1.2 or 1.3).
Cookies and browser storage
CADProps uses session cookies to identify a guest's temporary workspace and to maintain an account session after sign-in. Browser storage may also keep workspace state. Disabling these functions may affect file processing, sign-in or use of the workspace.
Analytics
We use Google Analytics to understand page visits and selected product actions so we can improve the site and its tools. Google Analytics may use cookies and similar technologies to process visit and device information. The workspace events we send filter out specific file information such as filenames.
Advertising and third-party cookies
On desktop, public content pages and the workspace use Google AdSense for vignette ads only. Advertising is disabled on phones. My files, shared-model viewers, connector pages and account-action pages do not load ads. Third-party advertising vendors, including Google, may use cookies or other identifiers to serve and measure ads based on a user's prior visits to this site or other websites. You can manage personalized ads in Google Ads Settings. Browser settings can also be used to manage cookies. You can also review opt-out choices for some participating third-party vendors at aboutads.info.
Visitors in the EEA, the UK and Switzerland are asked for consent before Google Analytics and advertising cookies are used. You can change your choice at any time with Privacy settings at the bottom of each page.
File storage and expiry
Guest files are automatically deleted about one hour after upload, including their previews and calculated results. The workspace shows the exact deadline. You can delete files earlier from the file menu, or clear the temporary workspace.
Signed-in uploads are saved to your private My files space (200 MB, up to 100 files). Files and their results are automatically deleted after 90 days without use by the owner. Opening a saved file or downloading its original starts a new 90-day period; viewing the file list or opening a share link does not. You can delete saved files anytime. Deleting a saved source also removes its online results and disables its share links.
Share links expire after the selected 7 or 30 days and can be stopped earlier. Processing limits and formats are listed in the specifications.
CADProps in Claude and other conversation platforms
The CADProps connector uses a browser upload link: the file you choose is sent to CADProps servers for the inspection or conversion you request. The assistant receives the file name and a limited summary, including available dimensions, volume, area, units, accuracy notes, warnings and operation links. The model-facing tool result does not include geometry. The embedded viewer retrieves a display mesh or saved thumbnail using a short-lived read-only preview token. Because the viewer appears inside the conversation platform, that platform's own privacy policy also applies to what it displays. A ChatGPT version is not publicly available.
Guest files, previews and results are automatically deleted about 1 hour after upload. Preview tokens last up to 10 minutes, conversion download links up to 30 minutes and workspace handoff links up to 15 minutes. Upload links last 30 minutes and accept one completed upload. Links may expire sooner when the file expires. Opening a handoff link transfers access to your browser session or account and disables the old connector references and links. Handoff does not automatically save the file or extend its expiry. The normal temporary-file rules apply until you choose to save it; saved files then follow the account retention rules above.
For abuse prevention and capacity planning, CADProps keeps usage records for approximately 90 days, then removes them through scheduled cleanup. These contain a pseudonymous principal identifier, client, operation, input and output formats, byte count, outcome and timestamp; they contain no file names or file contents. Where the platform provides an anonymous identifier, CADProps uses a keyed hash rather than storing that identifier directly. Guest processing does not ask for your name, email address or unrelated conversation content.
CADProps does not sell uploaded files or model data and does not use them for AI training. Processing and storage use the CADProps servers in the United States described below; Cloudflare delivers the website and forwards requests. The conversation platform's own data practices are separate from CADProps's.
You can decline to upload, disconnect the connector in your platform settings, or transfer a file to the workspace to use its available file controls. Disconnecting does not immediately delete files already uploaded; their automatic expiry still applies. For a deletion request, email support@cadprops.com with the file name and approximate upload time (or your account email for an account file). Do not email active access tokens or credential-bearing links.
Where data is hosted
CADProps servers that process and store files run in the United States. Files from visitors in other countries are sent to these servers over HTTPS.
Service providers
We use a small number of providers to run the site: Cloudflare delivers the website and forwards requests to our servers; Google provides Analytics, AdSense, the consent message and optional Google sign-in; Gmail sends account emails such as registration and password-reset links. CAD files are processed on CADProps servers and are not sent to these providers for processing.
Who can access your files
Uploaded files are not public. Shared models are visible only to people with the share link. Only CADProps operators can access stored files, and only to run the service, investigate processing errors or answer a support request.
AI training
We do not use uploaded files, model data or measurement results to train AI or machine-learning models.
Requests about your data
To ask about or request deletion of files or account data, email support@cadprops.com. Include the email address of your account, or the file name and approximate upload time for a guest file.
