DynamicTrail ("the app") is published by Simard Software. It helps riders and clubs map and share ATV, snowmobile, bike, and running trails. This page explains what information the app collects and how it's used.
We use the information above only to operate the app's core features: displaying the map and your location, recording and saving trails and waypoints, showing groomer and shared-rider positions on the map, and letting club officers/trail masters review and approve content submitted to the trail systems they manage, and diagnosing crashes and errors. We do not sell your data, and we do not use the data described above — your location, your rides, your content — to target advertising. Advertising in the app is described in its own section below. Beyond the advertising SDK described there, the app contains no third-party analytics SDKs.
The free version of the app shows ads served by Google AdMob: a small banner on list and detail screens, and one full-screen ad after you finish something, such as saving a ride or sending a report. There are never ads on the map, while you are recording, or on a head unit.
To serve them, the AdMob SDK inside the app may collect and share with Google: your device's advertising ID, IP address, and general device information. We do not give AdMob your account details, your location history, your rides, or anything else you do in the app. How Google uses this data is described in Google's privacy policy and AdMob's data practices.
Where consent rules apply (for example in the EEA and UK), the app shows Google's consent form before any ad loads, and honors your choice — including choosing non-personalized ads or none. Where those rules apply you can also change or withdraw that choice at any time from Settings. You can reset your advertising ID or limit ad tracking in your device's system settings at any time. A Premium subscription stops ads being shown in the app.
Trails and waypoints you submit to a public trail system are visible to other users of the app, the same way they would be on a public trail map.
Your rider profile — username, profile picture, score, milestones and approval counts — is visible to other signed-in riders while it is public. A profile picture you add can be taken down by a site administrator; you can remove or replace it yourself at any time. Points you earn from volunteer hours count toward the score; the hours themselves, and the work they were logged against, are visible only to you and your club's officers.
Rides you record are private unless you deliberately share them, and you control who with:
People you share a ride with can view it only — they cannot edit it or pass it on. Separately, you may choose to submit part of a ride to a trail system as a proposed trail. That is a deliberate, separate action: the segment you pick becomes a normal public map contribution for that club to approve or reject, and the rest of your ride is not included.
We do not sell your personal information or share it with third parties for marketing purposes. Four service providers process limited data on our behalf: Google AdMob serves ads in the free version (see "Advertising" above), Google's Firebase Cloud Messaging delivers push notifications you subscribed to, the app store you installed from processes any purchase, and Resend delivers account email — your email address and a sign-in link, sent only when you ask to reset your password or when we need to verify your address. We may disclose information if required to do so by law.
Address search. When you ask the map to find a street address, or ask your car's dash by voice to navigate somewhere, the text you typed or said is looked up by your phone's own address service — Google's on Android, Apple's on iOS — under that company's privacy policy. It is never sent to our servers, and it is only sent when you ask for an address; searching for a trail, road or waypoint by name goes to our servers and nowhere else.
Two features broadcast a live position on the map, both entirely optional:
A grooming run is also a record the club keeps for state trail-fund paperwork. For each run we keep the start and end time, the machine and its meter readings, the notes the operator or an officer add, and the GPS track the phone recorded — including when the run was hidden from riders. From the track we work out which trails were groomed and how many miles. The track and the record are visible to the operator and to the club's officers, never to the public. Because the club may have to produce these records for audit for years after a grant, they are kept with the club's records and are not deleted when the run ends; if you delete your account, your name is removed from them and the record itself stays with the club.
Both can be stopped at any time from within the app. If not stopped manually, a session automatically expires and its last known position is no longer shown. We do not keep a historical trail of these live positions — only the most recent position is stored while a session is active, and it is discarded once the session ends or expires.
This is not an emergency service. It does not contact 911, a dispatcher, the Maine Warden Service, or anybody with a duty to respond. If you need emergency help, call 911 — or text 911 if you cannot call.
If you ask other riders for help, the following becomes visible to the people riding with you, to other riders who have the same trail system open in the app, to the officers of the clubs that maintain it, and to riders who watch that system for alerts:
Unlike a live location share, the request itself is kept as a record. Your moving position is discarded when the request ends, exactly as a live share's is — but where you were when you asked, and what you said, are kept. Standing a request down stops the broadcast and keeps the record. You can see everything you have ever sent under More → Calling for help.
People who offer to come are volunteers. We do not select, train, verify, direct or dispatch anybody, and nobody is obliged to respond.
Emergency contacts you add are stored only on your own phone and are never sent to us. When you ask for help the app pre-fills a message in your phone's own messaging app; you send it, over your own mobile plan. We never see those numbers, and they are deleted from the phone when you sign out.
We cannot guarantee that an alert will be sent, delivered, received, read or acted upon, or that anybody will respond. Delivery depends on mobile and satellite coverage, weather, your battery, your phone's Do Not Disturb and power-saving settings, your carrier, and Apple's and Google's notification services.
Content you submit remains associated with your account until removed by you or by an authorized club officer/administrator for the trail system it belongs to. Live location data is retained only for the duration described above.
Deleting your account: you can delete your account at any time from inside the app (profile button → Delete Account), or by following the steps at dynamictrail.com/delete-account. Deletion permanently removes your sign-in account, your recorded rides and any shares of them, your trail reviews and condition reports, event RSVPs, club memberships and pending join requests, riding-group memberships, your rider profile, contribution points, profile picture, follows in both directions and check-ins, notification settings and device registrations, and any live-location data. Trails and waypoints you contributed to public trail systems remain on the map — including any segment you submitted from a ride — but your name and account id are removed from them. The same applies to operational records a club relies on: maintenance reports, volunteer hour logs, grooming history and landowner records keep their dates, hours and content, with your name and account id removed.
DynamicTrail is not directed at children under 13, and we do not knowingly collect information from children under 13.
Data is transmitted over encrypted HTTPS connections. Authentication is handled by a dedicated identity provider (Keycloak) — the app and its servers never see or store your password directly.
If this policy changes, the updated version will be posted at this same address with a revised "Last updated" date.
