HullSense LLC ("HullSense," "we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the HullSense mobile application and associated hardware device (collectively, the "Service"). Please read this policy carefully. If you do not agree with its terms, please discontinue use of the Service.

1. Information We Collect

1.1 Account Information

When you create a HullSense account, we collect:

  • Email address
  • Password (stored in encrypted form via Firebase Authentication)
  • Name (optional, if provided)

1.2 Device Data

The HullSense hardware device transmits the following data to our servers:

  • Battery voltage readings and calculated charge percentage
  • Bilge pump activation events, duration, and activation count
  • Device connection type (Bluetooth, WiFi, or cellular)
  • Signal strength
  • Timestamps of all readings and events

1.3 Location Data

With your permission, the HullSense device collects GPS coordinates from its onboard GPS module. This location data is used to:

  • Display your vessel's position on the in-app map
  • Support geofencing alerts when your vessel moves outside a defined area
  • Calculate distance from your home dock

Location data is transmitted only when the device has an active GPS fix. You may disable geofencing features within the app at any time.

1.4 Usage and Technical Data

We may automatically collect certain technical information, including:

  • App version and device operating system
  • Crash reports and error logs
  • Feature usage patterns (e.g., which screens are visited)

This data is used solely to improve the reliability and performance of the Service.

2. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and maintain the HullSense Service
  • Send push notifications and alerts for battery, bilge, and geofence events
  • Process subscription payments via Stripe
  • Respond to customer support requests
  • Monitor and improve app performance and reliability
  • Comply with legal obligations

We do not sell, rent, or trade your personal information to third parties for their marketing purposes.

3. How We Share Your Information

3.1 Service Providers

We share data with trusted third-party service providers who assist us in operating the Service, including:

  • Firebase (Google LLC) — authentication, database, and push notifications
  • Stripe, Inc. — subscription payment processing
  • Hologram, Inc. — cellular data connectivity for LTE-enabled devices
  • Google Maps Platform — map display within the app

These providers are contractually obligated to protect your data and may not use it for their own purposes.

3.2 Legal Requirements

We may disclose your information if required to do so by law or in response to valid legal process, such as a subpoena, court order, or government request.

3.3 Business Transfers

In the event of a merger, acquisition, or sale of all or a portion of our assets, your information may be transferred as part of that transaction. We will notify you via email or prominent notice in the app before your data is transferred and becomes subject to a different privacy policy.

4. Data Retention

We retain your account and device data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law or for legitimate business purposes such as fraud prevention.

Device sensor readings (voltage, bilge events, location history) are retained for up to 12 months by default. You may request earlier deletion by contacting us.

5. Data Security

We implement industry-standard security measures to protect your information, including:

  • Encrypted data transmission (TLS/HTTPS)
  • Firebase Security Rules restricting data access to authenticated users
  • Device authentication tokens stored securely in hardware flash memory

No method of transmission over the Internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee absolute security.

6. Your Rights and Choices

Depending on your location, you may have the following rights regarding your personal data:

  • Access — request a copy of the data we hold about you
  • Correction — request correction of inaccurate data
  • Deletion — request deletion of your account and associated data
  • Portability — request your data in a machine-readable format
  • Opt-out of notifications — manage push notification preferences in your device settings or within the app

To exercise any of these rights, contact us at privacy@hullsense.io.

7. Children's Privacy

The HullSense Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately and we will delete it.

8. Third-Party Links

The Service may contain links to third-party websites or services. We are not responsible for the privacy practices of those third parties and encourage you to review their privacy policies.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy in the app and, where appropriate, sending an email notification. Your continued use of the Service after changes become effective constitutes your acceptance of the revised policy.
