Common things

It says "Flat horizon" instead of a ridge

The terrain for that spot has not downloaded yet, or the spot is outside the coverage of the open elevation data, which runs from about 60° N to 56° S. Connect once and reopen the place; if it still says flat horizon, it is outside coverage and the times fall back to the standard flat-horizon ones.

The live view points the wrong way

Phone compasses drift, especially near metal and in cold weather. Tap the sun or moon where you actually see it in the live view and the correction is remembered for that session.

First light looks too late

That is usually the point. In a valley the sun can clear the skyline an hour or more after the flat sunrise every other app reports. The Today screen shows the gap, and the skyline screen shows the ridge angle causing it. If the ridge angle looks wrong for where you are standing, that is worth an email.

Times are off by an hour

Ridgelight uses the time zone of the place you are looking at, not the one your phone is in. Looking at a spot in another zone will show that zone's local times.

What the app does with your data

Your location is never sent to us, and never attached to anything recorded. Apple sees it when the app fetches your cloud forecast. There is no account and no advertising. The app fetches public elevation tiles, map imagery and a cloud forecast, and sends anonymous usage data and screen recordings with your place names and coordinates masked out — switchable off in Settings. The privacy policy is short and says exactly what each one does.
