Privacy Policy · Last updated: October 6, 2026

1. Overview

NetCarve (“the App”) is a free, ad-free, fully offline subnet and CIDR calculator published by Across Cloud LLC (“we”, “us”). This Privacy Policy explains what information the App does and does not collect when you use it. By using NetCarve you agree to this policy.

2. Information We Collect

The App does not collect, store, transmit, or share any personal information or usage data.

• No account, sign-in, or registration is required.
• No names, email addresses, phone numbers, or contacts are collected.
• No location data is collected.
• No device identifiers, advertising IDs, or IP addresses are collected.
• No analytics, crash-reporting, or tracking tools are used.

3. Internet Access

NetCarve does not request or use the Android INTERNET permission. Every subnet calculation, address conversion and VLSM plan is performed entirely on your device. The App is designed to work in air-gapped and secure data-centre environments where network access is restricted.

4. Data Stored on Your Device

NetCarve can optionally keep a short list of calculations you choose to save (the “History” feature). This list is stored only in the App's private local storage on your device using the operating system's preferences store. It is never uploaded, synced, or shared. Clearing the History in the App, or uninstalling the App, permanently deletes it.

5. Permissions

NetCarve requests no sensitive Android permissions. It does not access the camera, microphone, storage, location, contacts, or network. The only operations that may open an external application are the optional links on the About screen (GitHub and Privacy Policy), which open your web browser only when you tap them.

6. Third Parties

The App contains no third-party advertising, no third-party analytics, and no third-party SDKs that collect data. The App uses the open-source url_launcher plugin solely to open links you explicitly tap.

7. Children's Privacy

NetCarve is a professional networking utility suitable for all ages. Because it collects no data at all, it does not knowingly collect information from children or anyone else.

8. Data Security

Since no data leaves your device and none is transmitted, there is no data for us to secure or for a third party to breach.

9. Open Source

NetCarve's complete source code is public and MIT licensed at github.com/codex-zubair/Net-Carve. Anyone may inspect the code to verify these privacy claims.

10. Changes to This Policy

If this policy changes, the updated version will be included in a future app update and published on this page.
