FAQ
Is it free?
Yes. Forecast, safety analysis, map, trips and retrieve are free. Pro removes alert limits and unlocks pro tools; payment via Telegram Stars.
Where does the forecast come from?
Open models ICON, ECMWF and GFS via Open-Meteo. Wind at launch height is computed from pressure levels, not from the 10-metre wind.
Which sites are available?
A curated directory plus worldwide sites from the open ParaglidingEarth database — the bot fetches the ones near you. You can add your own.
Can I trust the bot's rating?
It's a hint, not a permission to fly. Assess conditions at launch yourself and never fly alone.
Which languages?
18 languages including English, German, French, Italian, Spanish, Turkish and Russian.
What about my data?
We store only what alerts need. Location is rounded to about a kilometre. You can delete everything in your profile.
