AltitudeNow — last updated 2026-08-10
Short version: AltitudeNow has no account, no advertising or analytics SDKs, and no developer-operated cloud. Your altitude sessions stay on your device unless you explicitly export a file with the system share sheet.
Nothing. AltitudeNow does not collect, store, transmit, sell, or share personal information with the developer. The app does not create a user profile and does not send altitude-session data to a developer-operated server.
AltitudeNow uses Core Motion only to access the device's built-in barometric pressure sensor and calculate relative altitude and atmospheric pressure. Measurements are processed on-device. Recorded sessions are stored only in the app's local sandbox.
AltitudeNow does not require GPS location for its core altitude-recording feature.
The optional Premium upgrade is a one-time non-consumable purchase processed by Apple through StoreKit. AltitudeNow receives only the entitlement state needed to unlock Premium features. Payment information is handled by Apple.
Premium users can export a recorded session as CSV using the system share sheet. AltitudeNow creates the CSV locally. You choose the destination in the system share sheet; AltitudeNow does not upload the file itself.
Deleting a session removes it from AltitudeNow's local storage. Deleting the app removes AltitudeNow's locally stored app data from the device. There is no AltitudeNow cloud copy maintained by the developer.
AltitudeNow is rated 4+. The app has no account system, advertising, analytics, or developer-operated data collection.
