Safety, Privacy & Consent
Plain-language version. AltiFenix is in beta; this page will be finalised before public launch. Questions: hello@altifenix.com.
Safety disclaimer
AltiFenix is not a primary altimeter. It is a backup and awareness aid that runs on a consumer Garmin watch whose barometer was not built or certified for skydiving.
Always jump with a certified visual altimeter, an audible, and an AAD. Barometric readings can lag, drift, or be wrong. Skydiving is inherently dangerous, and every decision under canopy and in freefall remains yours. You use AltiFenix entirely at your own risk.
What the app collects
During the beta, AltiFenix can send anonymous diagnostic data so the altitude and jump-detection algorithms can be improved and verified against real jumps. This is controlled by a Share Diagnostics setting on the watch — turn it off and nothing is captured or sent; everything stays on the device.
When it is on, the app records and uploads:
- Raw barometric pressure and temperature samples;
- An airborne GPS track of the jump;
- App events (phase changes, zeroing, jumps, alerts, settings changes, app version).
Each watch is identified by a device-derived code, not by your name, email, or Garmin account. Uploads go over HTTPS to a server hosted in the EU (api.altifenix.com) and are used only to develop and validate AltiFenix.
You can turn diagnostics off at any time, and you can ask us to delete a device's data by contacting hello@altifenix.com with the device code shown in the app's About screen.
