Privacy Policy

Last Updated: 1/7/2026

1. Overview

CheckWatch respect your privacy. This policy explains how we handle your data when you use the CheckWatch iOS application and our notification relay service. Our guiding principle is to collect the absolute minimum amount of data necessary to deliver critical notifications.

2. Data We Collect

We do not collect personal usage data, analytics, or user profiles. We only process data required for technical functionality:

  • Device Token: A unique identifier generated by Apple (APNs) allows us to send push notifications to your specific device.
  • License Key: Used to validate your subscription or access rights to the relay service. This is stored securely in your device's Keychain and verified against our database.
  • Notification Metadata: In the process of delivering a notification, transient data (hostname, service state, check output) passes through our relay. We do not persist this content; it is ephemeral and survives only as long as it takes to forward to Apple's Push Notification Service.

3. How We Use Your Data

Data is used exclusively for:

  • Service Delivery: Routing notifications from your CheckMK instance to your iOS device.
  • Fraud Prevention: Validating license keys to prevent abuse of the relay service.

4. Data Storage and Retention

On Device: Your CheckMK credentials and host addresses are stored locally on your device or in your iCloud Keychain. We never have access to your CheckMK server credentials.

Server-Side: We store your License Key and Device Token mapping in a secure Firestore database hosted by Google Cloud. This mapping is retained until you delete the app or request deletion.

5. Third-Party Processors

  • Apple (APNs): For delivery of push notifications to your device.
  • Google Cloud Platform: For hosting the secure relay infrastructure and database.

6. GDPR and Your Rights

If you are in the EU, you have the right to access, rectify, or erase your data. Since we do not collect personal profiles (name, email, etc.), we identify your data solely by your Device Token or License Key.

To exercise your rights, please contact support with your License Key.
