Cumulus Mobile — Support

This page is the support contact point for the Cumulus mobile application (iOS and Android, package aero.cumulus.app) and for the web application at app.cumulus.aero.

In one sentence: Cumulus is a professional tool used by flight schools and aero clubs. Accounts are created by the organisation you work or train with — there is no public sign-up — so your own Cumulus administrator is the fastest route for anything to do with access, and we handle everything else directly.

1. Contact us

Email	contact@cumulus.aero
Response time	Within one business day, Monday to Friday (Central European Time).
Languages	English, French, Spanish.

Write in whichever of those three languages you are most comfortable with. If your message concerns a specific flight, lesson or aircraft, please include enough to identify it — we cannot search your organisation's data on a description alone.

2. Account and sign-in problems

Cumulus has no public sign-up. Your account is created and managed by the training organisation or club you belong to, and so are your roles and the parts of the application you can see.

You cannot sign in, or you have forgotten your password — use "Forgot password" on the sign-in screen. If no email arrives, check the spam folder first, then ask your Cumulus administrator to confirm the address held on your account.
You have lost access to two-factor authentication — use one of the recovery codes issued when you enabled it. If you no longer have them, your administrator can reset the second factor for you.
You have no account yet — ask your organisation to create one. We cannot open an account on your behalf.
Something is missing from the app that a colleague can see — that is almost always a role or permission set by your organisation, not a fault. Your administrator can change it.

3. Reporting a problem in the app

So that we can reproduce it rather than guess, please tell us:

what you were doing, and what happened instead of what you expected;
the screen or section concerned (pre-flight, debriefing, logbook, map…);
the date and time, and your time zone;
your device and operating system version (for example iPhone 13, iOS 18.5);
the application version, shown at the bottom of the My Profile screen;
a screenshot, if the problem is visible on screen.

Safety first. Cumulus is used in flight. If a problem affects a flight in progress, do not troubleshoot it in the air: fall back to your organisation's paper or alternative procedure, complete the flight, and report it to us afterwards. No feature of this application overrides the pilot's authority or your organisation's operations manual.

4. Working without a network

Parts of Cumulus Mobile are designed to keep working with no connection: the pre-flight and post-flight forms, the debriefing, and the map's cached layers. Anything entered offline is stored on the device and sent to the server when a connection returns. A record is never shown as saved until the server has confirmed it. If an entry appears not to have reached the server after you regain coverage, reopen the screen before re-entering it, and tell us.

5. Your data

The data in Cumulus belongs to the organisation you work or train with, which is its controller. Requests to access, correct or erase your personal data are addressed to that organisation in the first instance — its administrator can produce a full export of your file directly from Cumulus. If you cannot reach it, write to contact@cumulus.aero and we will forward your request and assist in answering it.
