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.
When you create a HullSense account, we collect:
The HullSense hardware device transmits the following data to our servers:
With your permission, the HullSense device collects GPS coordinates from its onboard GPS module. This location data is used to:
Location data is transmitted only when the device has an active GPS fix. You may disable geofencing features within the app at any time. Automatic trip logging can be disabled in app settings, which stops route recording.
We may automatically collect certain technical information, including:
This data is used solely to improve the reliability and performance of the Service.
If you choose to enable SMS text alerts (a Pro subscription feature), we collect your mobile phone number. By providing your phone number and enabling SMS alerts, you consent to receive automated text messages from HullSense regarding your vessel's status, including battery alerts, high-water detection, and geofence events.
Your phone number is shared with Twilio, Inc. solely to deliver SMS messages on our behalf. We do not share your phone number with any other third parties for marketing purposes.
We use the information we collect to:
We do not sell, rent, or trade your personal information to third parties for their marketing purposes.
We share data with trusted third-party service providers who assist us in operating the Service, including:
These providers are contractually obligated to protect your data and may not use it for their own purposes.
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.
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.
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, water level readings, location history) are retained for up to 12 months by default. You may request earlier deletion by contacting us.
We implement industry-standard security measures to protect your information, including:
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.
Depending on your location, you may have the following rights regarding your personal data:
To exercise any of these rights, contact us at support@hullsense.io.
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.
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.
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.
HullSense offers optional SMS text alerts to Pro subscribers. By enabling SMS alerts in the app, you consent to receive automated text messages from HullSense at the phone number you provided. Message and data rates may apply. Message frequency varies based on device activity — typically low frequency, only when alert conditions are triggered. You can opt out at any time by disabling SMS alerts in the HullSense app Settings, or by replying STOP to any message. For help, reply HELP to any message or contact support@hullsense.io.
If you have questions or concerns about this Privacy Policy, please contact us:
Pro subscribers receive a daily Boat Health report generated each morning at 7 AM. To produce these summaries, HullSense sends derived sensor data to Anthropic, PBC — a third-party service that generates the report text using a large language model (AI). Anthropic acts as a sub-processor on our behalf and is subject to the data-handling commitments described below.
We send only the information needed to generate the report — no raw personally identifiable information is included. Specifically:
Anthropic processes the above data solely to generate the report text returned to HullSense. Anthropic does not retain this data beyond what is required by its standard API terms, and we do not permit Anthropic to use your data to train its models. For more information, see Anthropic's privacy policy at anthropic.com/legal/privacy.
HullSense retains the generated report text for up to 30 days so you can view past reports in the app. The underlying sensor data used to generate the report is retained according to the standard device data retention policy described in Section 4.
Boat Health reports are a Pro feature. If you do not want your sensor data sent to Anthropic, you can disable Boat Health reports in the HullSense app settings at any time. Disabling this feature does not affect your Pro subscription or any other Pro features.
