How it works
Three steps, and the first two need no connection at all.
- Share any link to “ČITTAM Capture Lab” from the Android share sheet — a browser tab, a chat message, a video.
- Links wait in an inbox on your phone. Capture ten or a hundred; nothing is sent anywhere.
- One tap copies the batch and opens ČITTAM Linkbook, where you paste it into your workspace and every link becomes a scannable QR record.
Capture Lab itself needs no account. ČITTAM Linkbook, where the batch lands, needs a free ČITTAM account.
Why is Capture Lab separate?
ČITTAM Linkbook remains the cross-platform home for building documents and QR exports. Capture Lab adds one Android-only ability the PWA cannot provide: save a shared link and return immediately to the app you were using. Keeping it separate makes it optional, account-free, local-only, and without internet permission. Linkbook works without it.
No system permissions, by construction
- No internet access
- Links stay on this phone
- Export only when you tap
Read the technical proof
The app requests no system permissions — not even INTERNET. Without INTERNET permission, it cannot upload captured links to analytics, an account, or a server. It only copies URLs to the system clipboard when you choose an export and opens Linkbook; nothing is uploaded automatically. Captured links stay on your phone until you choose that handoff. The permission list of every release is verified on the signed APK and published with its release notes; its only entry is a self-defined AndroidX hardening guard that grants access to nothing.
