Frequently Asked Questions

Your mobile apps like AltimeterThree will keep all of their flights — they're stored locally on your device. However, you will no longer be able to view, analyze, and share them online through FlightLab.

If you don't have your flights saved on a mobile app, you should export and save them to your hard drive before cancelling your account.

No! You can import flights from other altimeters. We support multiple file formats, and new formats are added as users suggest them.

No, groups are a handy way to share and view flights, but the flights never really leave their owners — they're just viewed by group members. When a group is deleted, all flights stay safely with their original owners.

In the AltimeterThree app, go to Settings and enable Cloud Sync. Sign in with your FlightLab account, and your flights will automatically sync to the cloud. Any new flights you record will sync automatically when you have an internet connection.

Yes. Your flight data is encrypted in transit and stored securely on our servers. We never share your data with third parties, and you always have full control over what you share publicly or with groups.

Yes! You can generate a shareable link for any individual flight. Anyone with the link can view the flight data and charts, even if they don't have a FlightLab account.

We currently support AltimeterThree native format, as well as common CSV formats from popular altimeters. If your altimeter's format isn't supported yet, let us know!

FlightLab works on all modern browsers including Chrome, Safari, Firefox, and Edge. The web app is fully responsive and works great on desktop, tablet, and mobile devices.

Open the flight you want to delete, click the menu icon, and select "Delete." Deleted flights are moved to trash and can be recovered within 30 days. After that, they are permanently removed.

FlightLab is a web-based application and requires an internet connection. However, your AltimeterThree mobile app stores flights locally, so you can always view them on your device even without connectivity.

Go to the Groups section and click "Create Group." Give your group a name, then invite members by email. Once they accept, they'll be able to see flights shared with the group.

We accept all major credit cards (Visa, Mastercard, American Express, Discover) through our secure payment processor, Stripe.

Go to Settings in the app and select "Account." From there you can update your password, email address, and other account details.

By default, your flights are private and only visible to you. You can choose to share individual flights via link, add them to groups, or keep them completely private. You're always in control.

You can reach our support team anytime. We're happy to help with any questions or issues.
