Nautbot Privacy Policy

Last updated: 2026-06-10

Nautbot is a map-based app for seeing what's happening near the water. We try to collect as little as possible. This policy explains what we collect, why, and your choices.

Anonymous usage analytics

If enabled, Nautbot shares anonymous usage statistics through TelemetryDeck to help us understand which features are used and improve the app. This includes:

• An anonymized per-install identifier (a salted hash of your device's vendor identifier) — not linked to your name or Apple ID.
• Basic device metadata: device model, OS version, architecture, locale, region, timezone, screen size, accessibility settings, app version/build, and whether the build is from TestFlight.
• A coarse, server-rounded (hourly) timestamp.

We do not collect your IP address, advertising identifiers, cookies, or precise/GPS location through analytics. This data is never used to track you across other apps or websites.

Your choice: analytics are controlled by "Share Anonymous Usage Stats" in Settings ▸ Privacy. When off, no usage data leaves your device.

Feedback you send

If you use Send Feedback, we receive the message you write, the optional email address you provide, and basic device/version metadata (model, OS version, app version/build, locale) to help us reproduce issues. Submissions are stored on our server and emailed to us; we also record the request's IP address for abuse prevention. We use this only to respond to and act on your feedback.

Location

Nautbot uses your device location to center the map, find nearby places, and scope marine-warning alerts. Most processing happens on your device. To fetch weather, tide, and nearby-vessel information, the map's center coordinates are sent to our backend services. We do not store a history of your location.

Notifications

If you opt in to marine-warning notifications, Nautbot checks for active warnings near your last known location in the background and may post a local notification.

Third-party data sources

Nautbot displays data from third parties, including NOAA / National Weather Service, Open-Meteo, AISStream.io, OpenStreetMap, Wikipedia, and Apple Maps. See the in-app Data Sources screen for the full list and licenses.

Data retention

Feedback submissions are retained as long as needed to act on them. Anonymous analytics are retained per TelemetryDeck's policies.

Children

Nautbot is not directed at children and does not knowingly collect personal information from children.

Changes

We may update this policy; material changes will be reflected here with a new "Last updated" date.
