CAD review, clearly

Privacy

Caddis is local-first. On mobile and in supported browsers you can open, measure, and mark up CAD files entirely on your device — no account, and nothing is uploaded. Your source drawing never leaves your device unless you explicitly choose to.

When you use Caddis Cloud (a Pro feature), we store what is needed to continue a review across devices: project metadata, the scene your device derives from the drawing, your review overlays (measurements, markups, visible layers, and view state), thumbnails, and — only if you separately choose to upload it — the original source file. Files are held in private cloud storage (Cloudflare R2) with project metadata in a managed database; source geometry and your review overlays are stored separately.

Accounts and sign-in are handled by Clerk; we verify your identity token and keep a minimal profile (an internal id, your email, and display name). Web subscriptions are processed by Stripe and mobile subscriptions by RevenueCat and the app stores — Caddis never receives or stores your card details.

You are in control. From your account page you can export your cloud data or delete your account at any time. Deletion revokes your sessions and share links immediately, soft-deletes your projects, and removes stored files within 30 days. We do not place your drawings in analytics or logs.

Our local-first promise

Cloud sync, source uploads, and share links are opt-in, per project. A local session is never turned into a cloud project unless you choose to save it.
