What MetarLab is, and is not

MetarLab reads published aviation weather back to you in plain language and puts official charts in front of you. It decodes; it does not author. Every number it shows comes from the authority that published it, and the original is always kept on screen next to the reading.

It is not an official source and must not be used as one. It is not an approved briefing service, it is not a flight-planning system, and nothing in it replaces the official briefing you are required to obtain. A decision to fly is yours, made against the authority's own publication. If MetarLab and the authority disagree, the authority is right.

The study material is written to help somebody prepare for the EASA PPL theory examinations. It is not the syllabus, it is not endorsed by any authority or school, and passing a quiz here is not evidence of anything.

Where the data comes from

Weather

METAR and TAF from the NOAA Aviation Weather Center. Winds aloft from Open-Meteo. Magnetic variation from the NOAA National Centers for Environmental Information. Airspace from openAIP.

Charts

Aerodrome charts and VFR sheets are published by the national AIS providers — ENAIRE in Spain, NATS in the United Kingdom, the SIA in France. MetarLab does not copy, re-host or alter them: your browser opens them from the provider's own servers. They remain the property of those providers and are subject to their own conditions of use.

Charts you upload yourself

Separate from all of the above, and the one thing here MetarLab does host. A subscription buys room for your own PDFs, kept privately against your account and served only to it. They stay yours; nobody at MetarLab reads them; there is no way to share one with another account. If you believe a file stored here infringes your rights, the terms say how to report it and it will be taken down.

Maps

Map tiles from Esri and its contributors.

Everything else on the site — the code, the wording, the decoding — belongs to whoever runs MetarLab. The flashcards you write and the charts you upload belong to you.

Using it

An account is yours alone

Do not share it. What happens under it is your responsibility, so keep the password to yourself.

Age

You must be at least fourteen, which is the age Spanish law sets for consenting to a service like this on your own account.

Do not break it

No scraping, no automated hammering, no attempt to reach another account's data. The upstream sources are free services that MetarLab is a guest of, and abuse here costs them, not only it.

It can stop

This is a personal project offered as it is, with no promise of uptime and no warranty. It may change or end. If that happens, your data is still yours: the app can hand you a copy of everything at any time, from Settings → Your data.

The rest of it

Privacy

What is held about you, why, who else sees it and how to take it back: the privacy policy.

Terms

What an account gives you, who you are buying from, and what happens to the files you upload: the terms.

Changing your mind

Fourteen days, and what cancelling does that a refund does not: refunds.

Law and jurisdiction

Spanish law applies. Nothing here takes away the rights you have as a consumer, which include being able to bring a matter before the courts where you live.
