Questions?

Is it really free?
Right now, yes — completely free while we're getting started. Our goal is to build something useful enough that people are happy to pay for it someday. No credit card required, no trial period, no feature gates.
How does it actually work?
When you sign up and set your location, WeatherCal pulls the forecast and generates a batch of calendar events tailored to your preferences — an all-day summary plus weather alerts. These sync to your calendar automatically and refresh throughout the day, so your forecast stays current without you doing anything.
How often does the forecast update?
It depends on how soon the day is. Today and tomorrow update five times a day. The next few days update twice daily. The rest of the 14-day window updates once a day. Near-term accuracy matters most, so that's where the refresh rate is highest.
What locations does it support?
Anywhere in the world. WeatherCal uses Open-Meteo for forecast data, which has global coverage. If you can find your city on a map, it'll work.
What weather data source do you use?
WeatherCal is powered by Open-Meteo, which aggregates data from national weather services around the world — including NOAA, DWD, MÊtÊo-France, and others. You're getting the same underlying data the professionals use, delivered straight to your calendar.
Will it clutter my calendar?
No. WeatherCal lives in its own calendar stream — you can toggle it on or off from your calendar's sidebar anytime. All events are marked as "free" so they never block your availability or trigger scheduling conflicts. Out of the box, all features are turned on so you can discover everything WeatherCal offers. If anything feels like too much, every event includes a link to your settings where you can turn off individual event types with a tap.
Can I customize what shows up?
Yes — you have full control. Toggle all-day summaries or weather alerts on or off, choose which alert types you care about (rain, wind, cold, snow, heat, or even nice weather), set your own temperature thresholds, and pick your preferred units. There are 16 settings in total, so you can dial it in to exactly what's useful for you.
How do I remove it?
However thoroughly you'd like. You can simply unsubscribe from the WeatherCal calendar in your app and the events disappear instantly. If you connected via Google, you can disconnect and revoke access from settings. Or you can delete your account entirely — all personal data is purged immediately.
Is my calendar data safe?
WeatherCal can only access the calendar it creates — it cannot read, modify, or delete any of your existing calendars or events. Your location is sent as coordinates only to fetch the forecast, not linked to your identity. There are no analytics cookies, no ad trackers, and no third-party data sharing. All data is stored on EU servers, and you can delete everything self-service at any time.

More convenient than you'd think.
