Privacy Policy

Gilman Labs built the Session app as a freemium app. Session records your outdoor activities (distance, elevation, route) and the moments (“marks”) you save along the way. The basic app is free, and an optional paid subscription (“Session Premium”) unlocks additional features.

This page explains what information the app uses, where it goes, and the choices you have. By using Session you agree to the practices described here. We do not sell your personal information.

The short version

• Your sessions, routes, marks, and photos stay on your device. Gilman Labs does not run a server that receives them, and we have no accounts or sign-in.
• The app does not show ads and does not use advertising or analytics services.
• A few features contact outside services (weather and map tiles). Those are listed below.

Information the app uses

Location. While a session is running, Session uses your device’s location (including in the background while your screen is off or the app is closed to the screen) to record your distance, elevation, and route. Location is only collected while a session is active, and a notification is shown while tracking. Your route and the coordinates of each mark are stored on your device. Session also checks your location while the app is open and idle so it can show GPS status.

Motion and barometer. Where your device has a barometric pressure sensor, Session uses it to measure elevation gain and loss. This data is used on the device and is not sent anywhere.

Photos and videos. Session can read the photos and videos in your device library so it can link the ones you took during a session to the nearest mark. They are not copied or uploaded. They are only shared if you choose to share a mark. When you use the camera button, Session opens your device’s camera app and saves the result to your normal photo library; Session does not access the camera itself.

Microphone (optional voice marks). If you turn on “Voice marks” and grant permission, Session listens through the microphone only while a session is active to detect the spoken word “mark”. Recognition runs entirely on your device. Audio is not recorded, stored, or sent anywhere. Turn the switch off at any time to stop listening.

Music information (iOS only). On iOS, Session can note the song title and artist that was playing in the Apple Music player when you made a mark. This is stored on your device.

Notifications. Android shows a notification while a session is recording.

Services the app contacts

Weather (Premium): When a Premium user saves a mark, the app sends that mark’s coordinates to Visual Crossing to retrieve current conditions. Visual Crossing also receives the device’s IP address. Weather data provided by Visual Crossing Weather.

Map tiles. To draw the background of your route map, the app downloads map images from a map provider. These requests necessarily reveal your IP address and the area of the map you are viewing to that provider. The Roads map uses OpenFreeMap, and the Terrain map (Premium) uses MapTiler. Your recorded route itself is drawn on your device and is not sent to the map provider.

Purchases. Subscriptions are processed by Google Play (Android) or the Apple App Store (iOS). We do not receive or store your payment details. We are told whether a subscription is active so the app can unlock Premium features.

Google Play services. The Android app uses Google Play services for location and billing, which have their own privacy policy. On iOS, Apple’s privacy policy applies to system services.

Sharing

When you tap Share on a session or mark, Session creates text (and any photos or videos you attach) and hands it to the app you choose, such as Messages. What that app does with it is governed by that app’s own policy. Shared text may include a link to a map showing the coordinates of the mark.

Log Data and crash reports

If the app crashes, Google Play or Apple may give us anonymous crash and performance reports, which can include your device model, operating system version, and the state of the app when the problem happened.

Your choices and your data

• You can turn off location, microphone, photo, or notification permission at any time in your device settings. Some features will stop working without them.
• You can turn off Voice marks with the switch on the main screen.
• Because your data is stored on your device, uninstalling Session removes it.
• You can cancel a subscription at any time in Google Play or the App Store subscription settings.

Security

We value your trust and use commercially reasonable means to protect the app and the data it handles. Because your sessions are stored on your device, keeping your device secure (screen lock, updates) also protects them. No method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.

Links to Other Sites

Session may contain links to other sites, including map and music links. If you open one, you will be sent to a site we do not operate. We strongly advise you to review its privacy policy. We have no control over the content, policies, or practices of third-party sites or services.

Safety

Session is a tool for recording activities. Stay aware of your surroundings and do not operate your phone in an unsafe way while hiking, biking, skiing, or driving.

Children’s Privacy

Session does not address anyone under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information, please contact us so we can take the necessary action.

Changes to This Privacy Policy

We may update this policy from time to time. We will post the new version on this page, so please review it periodically.

This policy is effective as of 11/06/2026.
