Privacy Policy

Last updated: September 2, 2026

The short version. Alpinac is built privacy-first. Your GPS tracks, ski history, and Apple Health data are stored only on your device and are never uploaded to us or anyone else. There are no accounts, no analytics, no ads, and no third-party trackers. The app makes one kind of network request — downloading public elevation tiles to build a mountain’s 3D map — and that request never carries your GPS track or any identifier.

Alpinac (“the app”, “we”, “us”) is an iPhone app that records your ski runs and reveals your trail map as you explore. This policy explains what data the app handles and how. By using Alpinac you agree to this policy.

No account required

Alpinac does not have user accounts. You do not sign up, log in, or give us your name, email, or any contact details to use the app.

What the app collects and how it is used

Precise location (GPS). While you are recording a session, the app reads your device’s GPS location to track your runs, calculate statistics (distance, vertical, speed), and reveal the parts of the mountain you’ve skied. Your GPS track is stored locally on your device only. It is never uploaded to us, and never shared with third parties. (See Map and terrain data for the one network request the app does make, which does not include your location track.)
Activity data. Run counts, vertical, speed, duration and similar metrics are derived from your GPS track and stored on your device alongside your sessions.
Purchases. Alpinac Pro is a single one-time purchase — there is no subscription and nothing renews. It is processed by Apple through the App Store. Apple handles your payment; we never receive or store your payment information. We may see anonymized, aggregated sales information through Apple’s App Store Connect.

Background location

With your permission, Alpinac can track your runs in the background — while your phone is in your pocket and the screen is off — and show live stats on your Lock Screen via a Live Activity. Background location is used solely to keep recording your ski session. You can change or revoke this permission at any time in Settings → Privacy & Security → Location Services.

Health data (Apple Health)

Alpinac works with Apple Health only if you allow it, and every part of it is optional — the app records ski days perfectly well with Health access turned off.

What Alpinac writes to Health. When you finish a ski day, the app can save it to Apple Health as a downhill skiing workout, including its duration and downhill snow sports distance. On Apple Watch, the workout is saved with heart rate and active energy collected during the session.
What Alpinac reads from Health. With your permission the app reads past downhill skiing and eligible snowboard workouts and their workout routes, so you can import ski days you recorded before installing Alpinac (including days that other apps, such as Slopes, Ski Tracks, or Strava, sent to Apple Health). During a live session on Apple Watch it also reads heart rate, active energy, and downhill snow sports distance to show live stats and to avoid saving a duplicate workout.
Where it goes: nowhere. Health data read by Alpinac is used on your device to build your ski history and stats, and is stored in the app’s own on-device database. It is never uploaded to us, never shared or sold to third parties, and never used for advertising, marketing, or any form of profiling — nor is it used for research, or disclosed to data brokers or insurers.

You can review or revoke Alpinac’s Health permissions at any time in Settings → Health → Data Access & Devices → Alpinac, or in the Health app under Sharing. Revoking access does not delete ski days already imported into Alpinac; you can delete those inside the app. Workouts Alpinac saved to Health are deleted in the Health app.

Apple Watch

If you use the Alpinac Apple Watch app, live session data (stats, heart rate, and start/stop commands) is exchanged directly between your iPhone and your own Apple Watch using Apple’s Watch Connectivity framework. This traffic stays between your two devices and never reaches us.

Map and terrain data

To draw a mountain in 3D, Alpinac downloads public elevation tiles for that resort’s map area. These requests go to alpinac-terrain.ajakerogers.workers.dev, a service we operate that relays the open Mapzen Terrain Tiles dataset (DEM from NASA SRTM, USGS 3DEP, and others, published via AWS Open Data). Once downloaded, tiles are cached on your device and are not requested again.

What such a request contains: the map tile coordinates for the resort you are viewing, and — as with any request to any website — your device’s IP address and standard connection metadata. Because the tiles cover a resort’s published map area rather than your position, the request indicates which mountain’s map is being built, not where you are on it.

What such a request does not contain: your GPS track, your recorded runs, your ski history, your Health data, your name or email, or any account, advertising, or device identifier. We do not use these requests to build a profile of you, and we do not combine them with anything else. Trail and lift map data itself is bundled inside the app, from OpenStreetMap contributors (ODbL) — reading a trail map involves no network request at all.

Notifications

Alpinac’s notifications — such as a reminder that you have arrived at a resort, or that a recording is still running — are scheduled locally on your device. Alpinac has no push notification server, and no notification content is sent to or through us.

No tracking, analytics, or advertising

Alpinac contains no analytics SDKs, no advertising, and no third-party tracking. We do not track you across apps or websites, and we do not build any profile of you.

Data sharing

We do not sell, rent, or share your data — to anyone, for any purpose. Your ski data leaves your device only when you choose to send it somewhere: Alpinac lets you export sessions as GPX files and share them through the standard iOS share sheet, and lets you save ski days into Apple Health. In both cases you choose the destination. The app’s own network activity is limited to downloading public elevation tiles, described under Map and terrain data.

Data retention and deletion

Because your data lives on your device, you are always in control of it. You can delete individual sessions, resorts, or areas inside the app, and deleting the Alpinac app from your iPhone permanently removes all of the data it stored, including its cached elevation tiles. Ski workouts you chose to save into Apple Health belong to Apple Health rather than to Alpinac, so they remain there after the app is removed — delete them in the Health app.

Children

Alpinac is not directed to children under 13 and we do not knowingly collect personal information from children.

Security

Your ski data is kept within the app’s on-device storage, protected by iOS’s standard app sandboxing and device security. The elevation tile requests described above are made over encrypted HTTPS connections.

Changes to this policy

If this policy changes, we will update this page and revise the “Last updated” date above.
