Privacy Policy

Last updated: March 2026

Overview

Labby ("the App") is a home lab monitoring application. We are committed to protecting your privacy. This policy explains what data the App collects, how it's used, and your rights.

Data We Collect

Short answer: almost nothing.

Labby stores all data locally on your device. We do not collect, transmit, or store any personal information on our servers. Specifically:

• Service configurations (names, URLs, ports, MAC addresses) — stored locally on your device only
• App preferences (theme, auto-refresh setting) — stored locally on your device only
• Uptime history — stored locally on your device only
• Purchase status — managed by Google Play; we receive a purchase token to verify your Pro entitlement

We do not collect names, email addresses, location data, analytics, usage statistics, or any form of telemetry.

Push Notifications

If you enable Push Alerts (a Pro feature), the following data is sent to our notification server (a Cloudflare Worker):

• Push subscription endpoint — a URL generated by your browser's push service (e.g. Google FCM)
• Service list — the names and URLs/ports of your monitored services, so the server can check their status

This data is stored in Cloudflare Workers KV and used solely to check your services and send you alerts when they go offline. You can remove all stored data at any time by disabling Push Alerts in Settings. Subscriptions are also automatically removed when they expire.

Docker Relay Agent

The optional Docker Relay Agent runs entirely on your own home network. It communicates directly between your device and your relay instance. No data passes through our servers. The relay uses a secret key that you configure — we never see or store this key.

If you choose to expose the relay externally using Cloudflare Tunnel (or similar), traffic between the app and the relay is encrypted via HTTPS. The tunnel runs on your own infrastructure — we do not operate or have access to your tunnel or relay.

Third-Party Services

The App uses the following third-party services:

• Google Play Billing — for processing Pro purchases. Google's privacy policy applies to payment data: policies.google.com/privacy
• Google Fonts — fonts are loaded from Google's CDN. Google's privacy policy applies.
• Cloudflare Workers — used for push notification delivery. Only your push subscription endpoint and service list are stored. See the Push Notifications section above.

Data Storage & Security

All app data is stored in your browser's localStorage. This data never leaves your device unless you explicitly use the Export feature to create a backup file. We have no ability to access, read, or recover your data.

Children's Privacy

Labby is not directed at children under 13. We do not knowingly collect any data from children.

Your Rights

Since all data is stored locally on your device, you have full control. You can:

• View all stored data through the App's Settings
• Export your data as a JSON file
• Delete all data using the "Reset All Data" option in Settings
• Uninstall the App to remove all associated data

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
