Privacy Policy
Summary: LMN Site Monitor Desktop does not collect, store or share any personal data. The app runs entirely on your device. On the very first launch, it sends one anonymous ping to count the installation — no IP address or personally identifiable information is ever stored.
1. Data controller
This application is developed and maintained by Francisco Moreno (). For any privacy-related enquiry you can contact us at that address.
2. Data collected by the application
On the first launch only, the app sends a single anonymous ping to our server to count the installation. The following table details exactly what is sent, what is stored, and what is discarded:
| Data | Sent | Stored | Purpose |
|---|---|---|---|
| Anonymous install ID (UUID) | Yes | Yes | Prevent duplicate counts. Not linked to any person. |
| App version | Yes | Yes | Track adoption of each release. |
| Operating system name & version | Yes | Yes | Understand which Windows versions are in use. |
| CPU architecture (x64 / arm64) | Yes | Yes | Plan future build targets. |
| System language / locale | Yes | Yes | Prioritise which languages to translate next. |
| Country (derived from IP by the server) | — | Yes | Geographic distribution. Derived server-side; IP is immediately discarded. |
| IP address | Yes* | Never | *Used only to derive country, then immediately discarded. Never written to disk. |
| Name, email or any personal identifier | Never | Never | — |
This ping is sent once per installation. After it succeeds, a local flag is stored on your device and the ping is never repeated.
3. Data processed locally (never leaves your device)
All monitoring data is stored in a local SQLite database on your
device (AppData\Roaming\LMN Site Monitor\). This includes:
- URLs and site configurations you add to the app.
- HTTP response times and uptime history.
- SSL certificate and domain expiry dates.
- SMTP credentials for email alerts (stored locally, never transmitted to us).
- App preferences and settings.
You have full control over this data at all times. You can delete it by uninstalling the app and removing the application data folder.
4. Third-party services used by the app
The app makes direct requests from your device to the following external services, strictly as required by features you explicitly use:
- Your monitored websites — HTTP/HTTPS pings to check uptime.
- Google Safe Browsing API — only when you enable malware scanning. Requires your own API key.
- URLhaus (abuse.ch) — only when you enable malware scanning. Requires your own API key.
- WHOIS servers — only when you perform a WHOIS lookup.
- Your SMTP server — only to deliver alert emails you configure.
We do not share any data with these services beyond what is strictly necessary to perform the requested function.
5. Legal basis (GDPR)
The anonymous install ping does not constitute processing of personal data under the GDPR, as no information relating to an identified or identifiable natural person is collected or stored. No IP address, name, email or device identifier is retained. The UUID generated is random and not linked to any individual.
6. Data retention
The anonymous installation record (UUID, version, OS, country) is
retained indefinitely for statistical purposes. It contains no
personal data and cannot be used to identify or contact you. You may
request its deletion by contacting us at with your install UUID (visible in
AppData\Roaming\LMN Site Monitor\.lmn-install-ping).
7. Your rights
You have the right to access, rectify or erase any data we hold about you. Since we do not store personal data, there is in practice nothing to access or erase. Should you have any concern, contact us at and we will respond within 30 days.
8. Changes to this policy
We may update this policy to reflect changes in the app or applicable law. The "last updated" date at the top of this page will always reflect the most recent revision. Continued use of the app after any change constitutes acceptance of the updated policy.
