Your drawings and your privacy

Accounts are optional

You do not need an account to use the workspace or publish a drawing. Publishing uses a private browser cookie to let you manage your uploads. Keep that cookie to retain access to removal controls; it lasts for up to a year.

What this site collects

Anonymous page-view analytics (Vercel Web Analytics), sent to this site's own origin — enough to see which pages are visited, not who visited them. Your light/dark theme choice is stored in localStorage if you set one. When you publish, a hashed browser identity and a short-lived hashed network identifier help us manage ownership and limit upload abuse.

Private Projects and billing

Projects accounts use Neon Auth with email/password or Google sign-in. We store your account ID, email, project descriptions, drawing files, revision notes, storage usage and subscription status. Google supplies your basic profile and verified email; we do not receive your Google password. Session cookies keep you signed in.

Private drawing files are held in a separate private Vercel Blob store. Only your signed-in account can access them unless you create a client link. Anyone with a client link can download its specific revision until the link expires, is revoked, or, for paid-plan links, your membership ends. Previously downloaded copies cannot be revoked.

Dodo Payments handles checkout, payment details, tax and billing records. We keep the customer and subscription identifiers and status needed to provide your plan, not card details. Accounts, authentication pages and client links are excluded from page analytics. Workspace analytics omit drawing and project identifiers. Separately, our own database records account setup, verification, project creation, saves, opens, client-link creation, checkout and error categories to find problems in these flows. These operational events reference your account but contain no drawing contents, file names, full URLs, card details or IP addresses. Signup-step counts use a daily hash of the network address and browser description to avoid counting repeated attempts; the raw address is not stored with these events and the hash is not linked to your account.

Ending a subscription returns your account to the free allowance: one project, three revisions, 25 MB and one one-day client link. Paid-plan links pause when the paid period ends. If your saved work exceeds the free allowance, you can download or remove projects, or upgrade to resume saving and sharing. Deleting a project removes access immediately and deletes its stored files; failed file deletions are retried automatically. Minimal billing records may remain for accounting and service operation. Private drawings are not published in the gallery or submitted to AI services.

Publishing a drawing

Publishing uploads your chosen file to public storage and saves its title and description. Uploads are not currently screened for NSFW content or sent to OpenAI. Your original file is stored unchanged.

Published files, titles and descriptions are stored and made available through the public gallery and share links. Anyone can download them. You can remove your drawings from the Publish page using the browser you published from. Removal stops access through this site and deletes the stored objects. Previously cached object links may remain accessible briefly; copies already downloaded by others cannot be removed. Do not publish confidential information.

What happens when you launch the workspace

Our hosted edition of OpenCADStudio runs in your browser. Local drawings are processed on your machine. When you choose Save to Projects, the selected drawing is uploaded to private storage. Opening a project revision downloads it into the editor. The editor does not receive your password or billing credentials.

Support

Email support@opencad.studio for account, billing, drawing access or deletion requests. Resend processes support messages and forwards them to the operator’s support inbox. We store delivery identifiers to prevent duplicate forwards.

Hosting

The site is served by Vercel, which, like any host, processes request logs (including IP addresses) to deliver the pages. This site adds no advertising, no third-party trackers. Approved drawing assets load directly from Vercel Blob storage, and the interactive viewer processes the viewing copy in your browser. The workspace is served from this site.
