Thợ Cam (ThoCam)

Privacy Policy

Last updated: October 17, 2026

Thợ Cam is a field toolkit for camera and network installers, developed by Kaifuz Studio. An account is optional — you only need one to use PRO across devices — and there is no advertising. The app works on your device and on the local network you connect it to. This page lists every case where it reaches beyond that.

Information Thợ Cam accesses

Depending on the features you use, Thợ Cam may ask for:

• Local network — to find, check and configure IP cameras, recorders and network devices on the site you are working on.
• Camera — to scan Thợ Cam QR tags and to take floor-plan and site photos.
• Photos — to open a floor-plan image or a site photo you choose.
• Location (Android only) — Android requires it to scan nearby Wi-Fi networks and to read the name of the Wi-Fi network you are on. Thợ Cam does not use or store your location.

The spirit level reads the device's motion sensor on the device; nothing is recorded.

What stays on your device

Your jobs, customer details, device lists, floor plans, sketches, photos, materials and price list, signatures and exported reports are stored on your device. Kaifuz Studio's account service (below) never receives any of this data. It leaves your device only when you share or export it yourself — for example a PDF report, a .thocam job file, a QR tag or a text summary — and it then goes only where you send it.

Camera passwords

Device passwords are never written into jobs, reports, QR tags, .thocam files or shared summaries. If you choose to save logins you use often, they are kept in your operating system's secure storage (such as the iOS or macOS Keychain or the Android Keystore), are never shown again in the app, and are never exported. QR tags are encrypted with a passphrase you choose; a few plain lines you can see before printing (installer, phone, install date, warranty end) are readable by anyone who scans the tag.

Talking to devices

Scanning, live view, configuration, PTZ, ping, port checks and traceroute connect directly from your device to the addresses you scan or type in. These connections never pass through Kaifuz Studio.

Optional account, activation codes and web purchases

If you choose to sign in (with Google, or with Apple on Apple devices) or use an activation code, the Thợ Cam account service at thocam.kaifuz.com, run by Kaifuz Studio on Cloudflare, stores:

• your email address and the account identifier Google or Apple gives us (we never see your Google or Apple password);
• your activation codes, their plan, expiry and number of devices;
• for each device using PRO: a random device identifier created by the app, a device name such as "Windows · PC-01", the platform and the app version, with activation and last-seen times;
• orders you place on the website: plan, amount, order code and the bank-transfer reference used to confirm payment (we never receive your bank login or card details);
• a security log of sign-ins and changes, including IP addresses, kept to prevent abuse.

When you are signed in on a phone or Mac, purchases made through Apple or Google are linked in RevenueCat to an identifier derived from your Thợ Cam account (not your email), so PRO also works on your other devices. Bank-transfer payments may be confirmed automatically through SePay, a Vietnamese payment-notification service that reports incoming transfers to our bank account.

Analytics and crash reporting

There are none. Thợ Cam contains no analytics, attribution, advertising or crash-reporting software and does not create an identifier of its own.

When Thợ Cam uses the internet

• Speed test. Running the internet speed test downloads and uploads test data to Cloudflare's speed-test service (speed.cloudflare.com), which sees your IP address as with any internet request.
• Purchases. PRO purchases are handled by Apple or Google, with RevenueCat managing purchase status. RevenueCat assigns an anonymous identifier, or, if you sign in, the account-derived identifier described above. We never see your card details.
• Links you open. The Map button opens Google Maps (in its app or your browser) with the address you entered for the job; the Call button opens your phone app. Support links and the rating prompt open the relevant app or store. What those services receive is governed by their own policies.

Data retention and deletion

You can delete a job inside the app, or remove all Thợ Cam data by clearing the app's data or uninstalling it. Saved logins can be removed in Settings. If you created an account, you can delete it in the app (Settings → Account → Delete account) or on thocam.kaifuz.com: this deletes your account, sessions and device records and removes your email from activation codes (purchase records are kept for accounting without your email), and asks RevenueCat to delete the linked customer. RevenueCat keeps the store purchase record needed to restore purchases. For questions, contact privacy@kaifuz.com.

Children's privacy

Thợ Cam is a professional tool, not directed to children under 13, and we do not knowingly collect personal information from children.

Changes to this policy

We may update this policy as Thợ Cam evolves. The latest version will always be available on this page.
