Sid Sub Sweep Privacy Policy
Effective date: October 30, 2026.
Developer: Sid Nguyen. Contact: sidwin@gmail.com.
Sid Sub Sweep (3S) is a free network diagnostic app. It does not provide an account system, developer-hosted scan backend, cloud history, analytics service, advertising SDK, or automatic result upload.
Information used on your device
The app reads local OS interface information and processes the targets you enter, ICMP replies and timing. Device names and MAC addresses are shown only when supported local sources provide them. Scan/host-ping results and network snapshots remain in memory; no hidden scan-history database is maintained. Closing the process clears in-memory results.
Network traffic you initiate
Starting a subnet scan or host ping sends ICMP packets to the chosen numeric target addresses. Targets and network operators can observe normal network traffic, including source/destination addresses. Subnet scans do not perform automatic reverse-DNS discovery.
When you explicitly resolve a hostname in Ping a Host, the OS-configured resolver receives that hostname under the OS/network's DNS policy. DNS traffic may leave your device and may not be encrypted. The app does not operate a cloud DNS service. A DNS request already sent cannot be retracted by Stop; late results are ignored after cancellation. The selected numeric address remains pinned during a ping run.
Export and sharing
Desktop Save CSV writes a file only where you choose. Share CSV explains that the file may leave your device, then opens the system share menu only after your confirmation. You choose the app, destination, recipient and send action. The app attaches only the requested CSV and does not automatically send messages. Other apps and recipients control their copies and may upload, sync or back them up.
Temporary share files are created in the app's cache/temp area. App-managed copies older than 24 hours are eligible for cleanup during a later share; this is not a guaranteed deletion deadline. Native share caches may persist until a subsequent share or OS cleanup. The app never deletes your separately saved exports or recipient copies. Android automatic backup is disabled and exclusion rules are declared; OS behavior and files saved outside the app remain outside those controls.
External links
More from Sid contains optional external links to the developer's websites and the Capture My Flag Android approved-tester beta page. No scan metadata or tracking parameters are attached. Opening a link exposes ordinary browser request information to the destination, whose privacy policy then applies. No link is prefetched automatically.
Your choices
Do not start a scan/ping on a network without authorization. You can stop probing, edit the target, decline sharing, close the app, and delete exported files using the destination's file controls. OS settings control available network permissions. Mobile peer names/MACs and certain iOS interface details are intentionally unavailable; the app does not bypass restrictions.
