Seaglass Privacy Policy
Sea Glass Cockpit ("Seaglass") · Last updated: 25 August 2026
Seaglass is a boating app: charts and navigation, anchor safety, a maintenance log, crew communication, media, games, and a boating community. This policy says what data the app handles, why, and what control you have. The short version: we do not sell your data, we do not show third-party ads, and features that share anything about you are off until you turn them on.
What we collect and why
- Account: email address, display name, and date of birth. The date of birth is used only to select age-appropriate features; it is stored privately and is never shown to other users.
- Location: used on your device for the chart, anchor watch, trip logging, and weather. Your position is shared with others only through features you explicitly turn on: crew/family location sharing (Life360-style, opt-in, revocable - turning it off deletes your published position immediately), anchor drag alerts to nearby boats, and marketplace listings that follow your boat (opt-in per listing).
- Content you post: posts, photos, videos, audio, maintenance logs, comments, marketplace listings, and pins. Public content is visible to other users; you can delete your own content.
- Contacts (optional): if you use contact matching to find friends, phone numbers are matched and immediately discarded - your address book is not stored. Accounts of users under 13 never upload contacts and are never discoverable by phone number.
- Messages and community activity: direct messages, group posts, friend lists, and reports you file. Blocking someone severs contact both ways.
- Diagnostics: basic operational logs (for example that a safety alert was sent) used to run the service. No advertising identifiers, no cross-app tracking.
What stays on the boat
Crew chat, the intercom, shared alarms, and multiplayer games can run entirely over the boat's own local network with no internet. That traffic is end-to-end encrypted with a key derived from your boat's invitation and never reaches our servers. Offline charts, downloaded music, and map packs copied between phones stay on the devices involved.
Children
Seaglass accounts require a date of birth at signup, and accounts are currently available only to people 16 and older. We do not knowingly collect personal information from anyone under 16; if you believe a younger person has created an account, contact us and we will delete it. A supervised family/kids mode with verifiable guardian consent is planned for a future release.
Third-party services
Seaglass runs on Google Firebase (authentication, database, storage, hosting) in the United States. Map, chart, and weather data are fetched from public services (OpenStreetMap, NOAA, USGS, and similar); those requests carry the map area being viewed, as any map app's do. Part-price lookups query retailer sites for the part number you entered. Music streaming links open in Spotify or Apple Music under their own terms. None of these receive your Seaglass account data from us.
Your controls
- Location sharing, discoverability, and audio/map sharing are individual switches, all off by default (map-pack sharing on the boat network defaults on because charts are public safety data - it has its own switch).
- You can delete your posts, listings, and media in the app.
- You can request account deletion, and export or review of your data, at the contact below. Deleting your account removes your profile, published positions, and content ownership records.
Important safety note
Seaglass charts and alarms assist good seamanship; they are not for navigation and never a substitute for official charts, a proper lookout, and your own judgment.
