Need help or want to report a problem? Email us at xappfactory-feedback@hotmail.com. Please include your app version (Me → About Avyline) and the region you were using.
Avyline asks for location permission only when you first use position-based features. Allow While Using the App to see your position and the slope under your feet, or Always if you want track recording to continue with the screen locked. Your location never leaves your device — see the Privacy Policy. If you denied the permission earlier, re-enable it in iOS Settings → Avyline → Location.
Avyline Pro is an auto-renewable subscription offered as a monthly plan, an annual plan with a 7-day free trial, and a one-time lifetime purchase. Pro unlocks unlimited region downloads and route planning. All safety features — slope alerts, look-ahead radar, avalanche hazard overlay, official forecasts, track recording and backtrack — are free and always will be.
To manage, cancel, or see renewal dates:
Purchases are billed to your Apple ID. Payment details are handled by Apple — we never see them. If you have a billing question, Apple Support handles the transaction; we can help with everything else.
Avalanche danger ratings are shown only where an official public warning service covers the region (for example avalanche.org member centers, SLF, and EAWS members). Regions without an official forecast honestly show No rating — we never substitute data from a neighboring area. Every forecast displays its source and publication time.
Slope angles are derived from digital elevation data with finite accuracy; the app shows the uncertainty next to each reading. Avyline is a decision-support tool, not a substitute for formal avalanche training, a current official forecast, or beacon / shovel / probe. If something on the map looks wrong, please tell us — terrain data corrections are treated as high priority.
