Privacy Policy

PoolLog (“we,” “our,” or “us”) is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use the PoolLog mobile application (the “App”).

Our Privacy Philosophy

PoolLog is designed with privacy as a core principle. We believe your pool data is yours and yours alone. We do not collect, track, or sell your personal information.

Information We Collect

Information You Provide

When you use PoolLog, you create and store the following information locally on your device:

  • Pool configuration details (volume, surface type, sanitizer system)
  • Water test results (chlorine, pH, alkalinity, etc.)
  • Chemical addition records
  • Maintenance logs and notes
  • Expense tracking information
  • Reminder preferences

Important: All of this data is stored locally on your device by default. We do not have access to this information.

Location Information

PoolLog uses your postal code to fetch weather data for your pool location. This is done through:

  • Postal Code Entry: You manually enter your pool’s postal code
  • Weather Service: We use Apple WeatherKit to fetch weather conditions
  • No Location Tracking: We do not request or store your device’s GPS location
  • No Location Permissions: The app does not require location permissions

The postal code you provide is only used to fetch weather data and is stored locally on your device.

Automatically Collected Information

We do not collect any analytics, crash reports, or usage data. PoolLog does not use any third-party analytics services, tracking pixels, or advertising networks.

How We Use Your Information

All pool chemistry calculations, recommendations, and data storage happen locally on your device. Your data is used solely to:

  • Provide water chemistry recommendations
  • Display test history and trends
  • Send reminder notifications (if enabled)
  • Track maintenance expenses
  • Fetch weather conditions for your pool location

iCloud Sync (Optional)

PoolLog offers optional iCloud sync to keep your data synchronized across your devices. If you enable iCloud sync:

  • Your pool data is stored in your private iCloud account
  • Data is encrypted in transit and at rest using Apple’s security standards
  • We do not have access to your iCloud data
  • Only you can access your synced data through devices signed into your iCloud account
  • You can disable iCloud sync at any time in the app settings

iCloud sync is powered by Apple’s CloudKit service and is subject to Apple’s Privacy Policy.

Data Retention

  • Local Data: Your data remains on your device until you delete the app or manually delete records
  • iCloud Data: If you enable iCloud sync, data remains in your iCloud account until you delete it or disable sync
  • Weather Data: Weather information is fetched in real-time and is not permanently stored

Children’s Privacy

PoolLog is not directed to children under the age of 13, and we do not knowingly collect information from children under 13. If you believe we have collected information from a child under 13, please contact us through the support options available within the App.

Data Security

We take data security seriously:

  • All data is stored locally on your device using Apple’s secure data storage
  • Optional iCloud sync uses end-to-end encryption
  • No data is transmitted to our servers
  • The app works completely offline

However, no method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee absolute security.

Your continued use of PoolLog after changes indicates acceptance of the updated policy.
