Upload & verify
Upload flight logs from your Nano V1 altimeter to the Altimeter Cloud. Each log contains a cryptographic verification signature generated by its encrypted firmware. We verify it’s genuine and unedited before adding it to your account.

Connect a device to upload
Plug your Nano in over USB and pick from every flight on it, without hunting through the drive. Chrome, Edge or Opera on a desktop.
Flight log upload & verify
Drag and drop or click to select your CSV flight log. If verification passes, it will be added to your Altimeter Cloud account where you can view charts, share flights, and add notes.
How does verification work?
Each Nano runs AES-256 encrypted firmware that generates a cryptographic signature from your flight data and settings. When you upload, our server checks it independently. If it doesn’t match, the log is rejected as modified.
Just verifying?
Upload as normal. Verified flights are stored on the Altimeter Cloud automatically.
Need a CSV from an ACLZ?
Upload either format and you can download both. An ACLZ holds exactly the same flight as the CSV in a fraction of the space, so this page doubles as a converter in both directions: send an ACLZ and take the CSV away, or send a CSV and get an ACLZ back.
