Frequently Asked Questions

How do I drop a marker?

Long press on the chart at the location where you want to place a marker. A marker form will appear so you can name it, choose an icon, and add notes.

How do I toggle chart layers?

Use the layer button to show or hide NOAA charts and bathymetry contours independently. Each layer can be toggled on or off based on your preference.

Does the app work offline?

Yes. Charts cache automatically for recently viewed areas, and you can download full NOAA chart regions for guaranteed offline use — draw an area on the map, see the size, and download it (free, up to 500 MB per region). Downloaded areas keep working with no signal, and you can refresh them when a newer chart edition is published.

What charts does FishHogs use?

FishHogs displays NOAA ENC (Electronic Navigational Chart) data for US coastal waters and the Great Lakes. Chart data is provided for general reference only and is not a substitute for official nautical charts.

Where is bathymetry (depth contour) coverage available?

Bathymetry is regional, not nationwide. It currently covers the Atlantic coast, the Gulf coast, the Great Lakes, Southeast Alaska, and Puerto Rico and the US Virgin Islands. Pacific coast coverage is limited to a small area near Long Beach, California, and there is no Hawaii coverage yet. This is a limit of the public NOAA survey data we build from, and we add regions as usable source data becomes available. NOAA charts, GPS, markers, the catch log, tides and conditions all work everywhere regardless — the regional limit applies only to the bathymetry contour overlay and FishHogs Depth mode.

Is my location data shared?

Your GPS location is processed on your device to show your position on the chart, and by default it is not stored or transmitted to our servers. The exception is opt-in group live-position sharing: if you turn on position sharing for a group, your location is transmitted to our servers (Google Cloud Firestore) and visible to that group until you turn it off. Sharing is off by default. Our ad provider (Google AdMob) may access approximate location to serve relevant ads — you can control this through the App Tracking Transparency prompt on iOS or your ad settings on Android. See our privacy policy for details.

How do I import markers from other apps?

Most chartplotters and fishing apps let you select markers, then share or export them as a GPX file. In FishHogs, open the Markers page and tap the import button to load a GPX file. Your imported markers will appear on the chart immediately. To export your FishHogs markers, use the export button on the same page. Note: some apps, like the Navionics Boating app, do not include marker details in their GPX exports — those markers will be imported with a default pin icon.

How do I get a copy of my data?

Email support@ndl.cc with the subject “Data Subject Request”, from the email address associated with your account so we know it is you. There is no charge. We will send you a copy of the personal data we hold — your account profile, entitlement status, synced markers and catches, group memberships, and any live-position or chat data still retained. For markers and catches on their own, you can export them yourself as a GPX file from the Markers and Catches screens in the app at any time. See your data rights for the full list.

How do I report a bug?

Use the feedback option in the app to report bugs. Include your device model, operating system version, and steps to reproduce the issue. Screenshots or screen recordings are helpful.
