Sentinel Firewall Privacy Policy
by PiTech (Progressive Information Technology)
Last Updated: July 23, 2026
Sentinel Firewall ("the app") is published by PiTech ("we", "us", "our"). This policy explains how the app handles your information. In short: Sentinel Firewall does not collect, store on our servers, or share any personal data.
The app does not collect personal information, does not require an account, contains no advertising, and includes no third-party analytics or tracking. We operate no servers that receive your data.
Uses Android's VPN service to filter traffic on-device. The VPN is local only — it never routes your traffic to any external server, and no data is collected.
Any settings or history the app creates are stored locally on your device only. This data never leaves your device, and uninstalling the app removes it.
Sentinel Firewall does not knowingly collect any information from anyone, including children under 13.
Sentinel Firewall is based on the open-source project NetGuard by Marcel Bokhorst (M66B), distributed under the GPL-3.0 license.
We may update this policy from time to time. Material changes will appear on this page with a new "Last Updated" date.
