Privacy policy

Blue Dolphin (the app) is published by Bombadil d.o.o., the controller for this policy. Contact: support@bluedolphin.bombadil.hr.

Short version

The app has no accounts, no ads, no analytics, no tracking and no crash reporting. Your position, your trips and everything else you create stay on your phone. We do not receive any personal data from the app.

What the app uses on your phone

• Location (GPS). Used on your phone to show your position on the chart, run the depth, speed and shore warnings, guide you to marks and along routes, and record the trips you start. Location is used in the background only while a trip is recording: Android then shows a notification, iPhone shows the blue location indicator in the status bar. When the recording stops, background use stops. Your position never leaves the phone, except the one point you open in Windy (see below).
• Camera. Used only when you tap the camera button to take a photo during a trip recording. Photos are stored on your phone with the trip. A photo is saved to your gallery or shared only when you choose to do so; sharing goes through your phone’s own share sheet, to the app you pick.
• Storage on the phone. Trips, photos, routes, marks, strait ratings, your boat profile and settings are stored only in the app’s storage on your phone. They are deleted when you delete them or uninstall the app. There is no cloud copy and no backup on our side.
• Diagnostic log (optional). Off by default. If you switch on “Diagnostic log” in Settings, the app writes navigation events (including positions, speeds and times) to a file on your phone, to help track down problems. The file never leaves the phone by itself: “Export log” hands it to your phone’s share sheet, and it reaches us only if you send it to us.

What the app downloads

The chart is bundled with the app, so it is never downloaded. The app fetches only public files, anonymously (the requests carry no personal data and no location):

• a small configuration file, https://bluedolphin.bombadil.hr/settings.json, on launch (bridge opening times and tuning values);
• the marine forecast and weather warnings of DHMZ, the Croatian meteorological service (prognoza.hr and meteo.hr), at launch and again when the data is older than about 6 hours while the app is open, or when you tap “Get new data”.

Like any download, these requests reach the server with your phone’s IP address; the app adds nothing about you. The app works fully offline when neither is reachable.

Buttons that leave the app

• Weather in the ring menu opens windy.com in your browser at the point you tapped. The coordinates of that point are part of the web address, so windy.com receives them. This happens only when you tap it.
• How to use opens this website in your browser.
• Email buttons (support, translation feedback, sending a strait rating) open your own email app with a prepared message. Nothing is sent until you press send there.

windy.com and your email provider have their own privacy policies.

When you write to us

If you email support@bluedolphin.bombadil.hr, we receive your email address and what you write. We use it only to answer you and to fix the charts and translations. People whose reports fixed the charts are credited by name in the app only with their permission. Ask us any time to delete your messages.

Changes

If this policy changes, the new version is published at the same address with a new date.
