Privacy Policy
Last updated: November 14, 2026
This Privacy Policy explains how LanSwift ("the App", "we", "us") handles information when you use our mobile and desktop application.
1. Local-Only File Transfers & Discovery
LanSwift is designed to transfer files and folders directly between your devices on your local Wi-Fi or local area network (LAN).
- No Cloud Storage: Files you send or receive are never uploaded to our servers or third-party file servers.
- Local Network Discovery: To discover nearby devices running LanSwift on the same Wi-Fi network, the App broadcasts and responds to UDP beacons containing your configured device name, platform type, a randomly generated local device ID, and transfer port number.
- Web Portal Mode: When you enable the HTTP Web App Server, files in your Send Queue are served locally over your LAN IP address for devices you share the URL/QR code with.
2. Data Stored Locally on Your Device
The App stores preferences locally on your device using standard platform storage (such as Android SharedPreferences):
- Custom device name and locally generated random device ID
- Transfer preferences (download folder path, auto-accept setting, folder organization, keep-awake preference)
- Local Send Queue / Web Portal file path list and in-memory diagnostic logs (which you can clear at any time in Settings)
3. Advertising (Google AdMob)
On Android (and iOS where applicable), LanSwift displays advertisements provided by Google AdMob. While LanSwift itself does not operate user accounts or analytics servers, the Google Mobile Ads SDK may automatically collect and share certain data to serve ads, limit ad frequency, and prevent fraud, including:
- Advertising ID (AAID / IDFA) and app set IDs
- IP address (used to estimate general/approximate location)
- Device information, ad impressions, interactions, and crash/performance diagnostics
You can learn how Google uses data from apps that use its services at
Google Partner Sites Policy,
and manage personalized ad preferences in your Android device settings (Settings → Google → Ads).
4. App Permissions
- Wi-Fi / Network Access: Required to discover peers and transfer files over your local network, as well as to load AdMob ads when internet is available.
- Storage / File Picker Access: Used strictly to read files/folders you explicitly choose to send and to save received files into your chosen download folder.
- Notifications & Foreground Service: Used to display live transfer progress and keep active transfers running reliably when the app is minimized.
- Battery Optimization Exemption (Optional): You may optionally grant unrestricted background battery usage so your phone can continue receiving transfers while idle.
5. Children's Privacy
LanSwift is a general-audience utility application and is not directed to children under 13 (or the applicable age in your jurisdiction). We do not knowingly collect personal information from children.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Updated versions will be posted on this page with a revised "Last updated" date.
