Privacy policy

Who we are

TrailDx is operated by NepGem. If you use TrailDx through a trek agency, that agency also sees the trip information it needs to run your trek. You can reach us with the details at the bottom of this page.

What we collect

We collect only what the features need.

• Account details: your name, email address and, if you add it, your phone number. Sign-in is handled by our sign-in provider, Clerk.
• Your profile and optional safety details: emergency contacts and, only if you enter them, medical or dietary notes. Medical details are shown to your guide only when you switch sharing on.
• Location, only as described in the next section.
• Photos you choose: a profile picture, and photos you attach to a trail report.
• What you write in the app: diary entries, trail reports, check-ins, group messages and feedback.
• Identifiers: your user ID and, if you allow notifications, a push token so alerts can reach your phone.
• Crash and performance reports, in builds where this is switched on. They are sent without personal details attached, through Sentry.

Location and Trek Mode

Location is off until you act. Trek Mode records your position on the trail, also with the screen off, so your guide and the people you chose can see where the group is. It starts only after you agree inside the app and give the phone permission, it shows a status while it runs, and it stops when you tap Stop. If Trek Mode is off, no track is recorded.

The app may also read your position once to show you on the map, and to attach it to a problem report only if you turn on Include my location. An SOS includes your position.

We use location for these features only. We do not use it for advertising, and we do not sell it.

SOS is not an emergency service

When you hold the SOS button to the end, TrailDx sends your position and message to your emergency contacts and to the people set up to receive alerts for your trip, by SMS and push notification. TrailDx is not an emergency service. It does not promise that anyone will respond or that you will be rescued, and an SMS or push message can fail or be delayed. In an emergency, also contact local emergency services and your guide.

Who can see your data

• Your trip: your guide, the agency that runs the trip and the viewers you chose can see the trip information, check-ins and position you share with the group.
• Service providers working for us: Clerk (sign-in), Sentry (crash reports), push notification services from Apple, Google and Expo, and an SMS provider that delivers SOS and alert messages. They handle data only to provide their service to us.
• We do not sell your data, we show no ads, the app has no advertising or analytics SDK, and we do not track you across other apps or sites.
• We may disclose information if the law requires it.

How long we keep it

Account data stays for as long as your account exists. When you delete your account there is a 14-day grace period, after which your personal data is deleted or made anonymous, apart from the records described on the delete-account page. We do not publish fixed retention periods for location tracks and SOS records on this page; ask us at the address below if you need to know.

Your choices

• Export your data: Profile > Settings > Privacy > Data export. The download link works for 7 days, and you can ask for one export every 24 hours.
• Delete your account: Profile > Settings > Privacy > Delete account, or see the delete-account page if you do not have the app.
• Turn off location or notifications at any time in your phone settings, and stop Trek Mode in the app.
• Ask us to correct your details, or ask any question about your data, using the contact details below.

Changes

If we change this policy we will update the date at the top. If a change affects what we collect, we will tell you in the app.
