Data Policy
Effective July 29, 2026
This is the plain-language companion to the Privacy Policy: an inventory of every kind of data Sea Legs handles, where it lives, why it exists, and how you get rid of it. If anything here ever disagrees with what the app actually does, that's a bug, so please tell us.
The inventory
| Data | Where it lives | Why it exists | How to remove it |
|---|---|---|---|
| Player id A random identifier. Anonymous unless you choose to save your captain, in which case it is tied to your Apple or Google sign-in, or to an email address you give us |
Your device + our servers (Google Firebase) | Links your save to your device, and to you if you saved it, so your world survives a reinstall | Delete it in the app: Home Port, Ship's Papers, Delete account. Or email us |
| Real-time location Your GPS position while playing |
Your device. We never upload a trail or history. If position sharing is on, your latest position is also sent as a live beacon (next row) | Moves your ship, clears fog, detects docking | Stops the moment you close the app (or instantly, if background sailing is off) |
| Shared position A live beacon: your latest position and heading, captain and company name, and current ship |
Our servers (Google Firebase), under an unguessable code for your world, not a stored track, just your most recent position | So a friend you invite into your world can see your ship on their chart. On by default; only someone holding your invite code can read it | Turn off "Share position with shipmates" at your Home Port. That stops the beacon and deletes it. Resetting your world removes it too |
| Home port coordinates Where you first opened the game |
Our servers, under your player id | Anchors your whole ocean: everything is measured from home | In-game reset (new world, new home) or email us |
| Island & port coordinates Points on real walkable paths near where you've played |
Our servers, under your player id | Your islands must stay where you found them, forever | In-game reset or email us |
| Revealed ocean (the chart) A coarse bitmap of map cells you've cleared of fog |
Your device + our servers | The water you have charted, kept between sessions and across a reinstall | In-game reset or email us |
| Game save Silver, ships, cargo, crew, banks, warehouses, statistics (e.g. total distance sailed as a number), plus which app version and platform you last played on |
Your device + our servers | It's your game, and losing it would be mutiny | In-game reset or email us |
| Captain's Log Ports visited (with timestamps), prices seen, trades and bank entries |
Your device + our servers | The in-game journal and the Factor's price book | In-game reset or email us |
| Names you type Captain name, trading-company name |
Your device + our servers | Founding your company is the point of the game | They can be anything, so don't use your real name if you'd rather not; reset or email us to remove |
| Crash reports Stack traces, device model, OS version, app version |
Google Firebase Crashlytics | So we can fix what breaks | Auto-expires on Google's schedule (90 days); no player id attached by us |
| Ad data Device identifiers, IP, ad views, only for optional rewarded videos |
Google AdMob | The only monetization in the game: ads you choose to watch | Governed by Google's policy; iOS App Tracking Transparency applies |
| Map requests Your IP + which map areas the app fetches |
Stadia Maps (street tiles), OpenStreetMap Overpass (walkable paths), transient service logs | Drawing the sea chart and finding real paths for ports | Not stored by us at all; providers keep normal server logs |
Honest notes
- Location-derived data sketches where you play. Your home port and discovered islands are real coordinates in your neighborhood. That's inherent to a GPS game. It's stored under a random id, never sold, and deleted on request, but if that trade-off isn't for you, Sea Legs isn't the right game, and we'd rather say so plainly.
- Inviting a friend shares your waters, and your position. An invite code contains your home port's coordinates (so your friend's game can build the same ocean), and while you both sail that shared world your live position shows on each other's charts. Only someone you give the code to can see it. You can turn position sharing off any time, and there's no need to send an invite if you'd rather keep your home harbor to yourself.
- Playing anonymously cuts both ways. You can play without ever making an account, and then we cannot identify you, which also means we cannot bring a captain back if you uninstall. Saving your captain to an account (Apple, Google, or an email address) is what makes a reinstall recoverable, and it is entirely optional.
- No analytics suite. There is no behavioral analytics SDK in the game. We learn what to fix from crash reports and from players who email us.
Deleting your account and data
In the app. Open Home Port, tap Ship's Papers, then "Delete account and all captains". This removes every captain on the device and everything stored for them on our servers: the profile, the charts, the fog, the account record itself, and the sign-in that ties them to you. It cannot be undone.
By email. If you have already uninstalled the game, or you would rather we did it, write to jeff@brickriverlab.com. If you saved your captain to an account, send it from that email address and we can find your data straight away. If you never made an account, tell us your captain or company name, since that is all an anonymous save carries.
Either way the deletion is permanent and takes effect immediately. We keep no backup copy of a deleted player, and nothing is retained afterwards except anonymous crash reports, which contain no account identifier and expire on their own.
