Drawing Work in Your Browser
We do not upload your drawing content during ordinary viewing, conversion or editing. By default, we do not persist your drawing or editing state after the session ends.
Downloads you choose to keep are ordinary files on your device. Your browser may retain site files, preferences and a random allowance identifier; “local by default” does not mean the browser leaves no trace of a site visit.
Save on This Device
Turn on Save on this device to retain drawings, thumbnails, names, timestamps and editing state locally. You can return to a recent drawing or clear it. Turning the option off and clearing saved drawings stops this persistence.
A saved block library can also contain drawing content. Its persistent local storage is an explicit choice, not an automatic upload.
Read-Only Share Links
Choosing Share displays an upload confirmation. After you confirm, a copy is stored on our server and a link is created. Anyone with that link can view, measure and download a PDF, but cannot edit, overwrite or download the original DWG/DXF.
Links last seven days by default. Revoking a link or reaching its expiry deletes the server copy. Links are not listed publicly or included in our sitemap, and they carry noindex instructions. A link is not password protected; share it only with people you intend to give access.
Save to Cloud
Cloud storage requires a free account. Choosing Save to Cloud displays a confirmation before uploading a copy to your own 100 MB space. You can reopen it on another device or delete it. Deleting the file removes the stored copy and releases its space.
We use account information and authentication records to sign you in and keep your files separated from other accounts.
Files Sent to the API
An API call is a separate, deliberate upload. The caller sends the drawing to our server for the requested operation and receives the result. Temporary input and output files are removed after the response completes. Failed or interrupted requests are cleaned up as part of request handling.
Keep your API key private. Request identifiers and counters used to enforce limits do not need to contain the drawing itself.
Site Usage and Service Reliability
We record limited usage information to understand visits, referral channels, country, device category and whether a drawing task started, completed or failed. We do not record drawing contents, drawing text or device fingerprints for analytics.
Where tracking requires consent and that consent has not been given, that tracking stays off. We do not show an analytics-consent popup by default. Some visits and later actions therefore cannot be connected, and an unknown referral remains unknown.
Messages You Send Us
The contact form sends your message, its category and any optional email address you provide to our service. We use this information to handle the request. Please do not include sensitive drawings or credentials.
Your Choices
Clear local copies on the device where they were saved, revoke share links, and delete cloud files from their controls. For questions about account or feedback data, send a privacy request through Contact.
