1. On the 'Map' tab, tap 'Info' to open the info panel, scroll down to the 'Trip Sharing' card, and tap it.
2. On first use, a message titled 'Before Using Trip Sharing, Please Confirm' will appear, explaining what will be uploaded, who can view it, how long it's retained, and that it cannot replace emergency calls.
3. After reading, toggle on 'I have read and understood the above information', then tap 'Agree and Continue'. You can also tap 'Read Full Privacy Policy' to view details.

To disable it later, tap 'Withdraw Consent and Disable Trip Sharing' at the bottom of the 'Create Trip Sharing' screen. This revokes the current link and immediately deletes the entire trip record on the server, including its name, times, route, location points, and link identifiers. If your phone is offline, the revocation is sent when connectivity returns; until then, the server data may still be viewable through the original link. The summary in iOS Trip History remains until you delete it manually.

1. After filling in the fields, tap 'Create shared trip'.
2. Confirm the trip details, departure time, return time, and overdue determination time in the summary, then tap 'Create Trip and Get Link'.
3. On first creation, iOS will ask if you allow notifications; it's recommended to allow notifications to receive return reminders.

• Share Link: Opens the system sharing panel with a message containing the trip name, scheduled return time, link, and a reminder to call 119 or 112 if unable to contact after the scheduled time.
• Copy Link: Copy the URL to manually paste into messaging apps.
• Display QR Code: Let the other person scan it in person.

The 'Trip Information' section displays the scheduled return time, overdue determination time, link expiration, and last upload time. The link validity period depends on the trip status; see Data Retention and Privacy.

• Location Reporting: Your phone sends a location update at the time or distance interval you chose (about every 10 minutes by default). Each update includes coordinates, time, and accuracy, plus altitude and battery level when available. If there is no signal, updates are stored on your phone and sent when the connection returns. The 'Pending Location Points' section on the trip page shows how many are waiting.
• 'Always' Location Permission: Without this permission, the app cannot continuously report your location in the background. The trip page will remind you and provide a shortcut to 'Open Location Settings'.
• Reminder Notifications: 30 minutes before the scheduled return time, you'll be reminded if you need to extend; at the scheduled return time, you'll be asked if you've completed the trip; 15 minutes before the overdue determination time, you'll be reminded of the upcoming overdue status (only if buffer time is set).
• Confirm right from the notification (version 1.1.9 and later): Press and hold (or pull down) a reminder notification to see 'I'm safely down' and 'Extend 2 hours' buttons. After unlocking your phone, one tap is enough, without opening the app, even if the app was closed. The buttons need the phone to be unlocked so a stray touch on the lock screen does nothing.
• Reminders keep coming after the planned time (version 1.1.9 and later): Once the planned return time has passed, you are reminded every 30 minutes, up to 6 times (about 3 hours). They stop as soon as you confirm you are safely down or revoke the link, and move with the new return time if you extend the trip.
• Detecting that you may be down (version 1.1.9 and later): After you have left the start point, if the app sees you back near it, moving at vehicle speed, or standing still for about 20 minutes at about the start's altitude, it notifies you 'You may be safely down'. Driving to the trailhead does not trigger it; you must first have walked for a while. This is only a reminder: the app never confirms for you, you still tap the button. Detection needs location permission ('Always' for the background).
• Extend 2 Hours: If you need more time, tap once to extend your scheduled return time by 2 hours and let your designated contact know the plan has changed.
• Safely Returned: After confirmation, location reporting stops and your designated contact's page will display 'Safely Returned'. The server keeps the entire trip record for 30 days so your contact can review it; the page shows the exact expiry time. While the link is valid, you can download a GPX from the page with reported location points, and the planned route and planned points if you chose to share them.
• Revoke Link and Delete Location Data: Once the server receives the revocation, it immediately deletes the entire trip record, including the trip name, times, route, planned points, location points, and link identifiers; the link and GPX download stop working. If your phone is offline, the revocation is sent when connectivity returns, and the original link may remain viewable until then. Download the GPX first if you need it.

After completion or revocation, tap 'Done, move to trip history' to move the trip out of the current screen and into the iOS Trip History list. A completed link stays available until its original expiry; an early revocation leaves a history summary without location points. History summaries remain until you delete them manually. Shared location points are not saved as a Tracks route; start track recording separately to keep a full track. Only one trip can be in progress at a time.

Your designated contact can open the link on their phone or computer browser (in the form of akimap.app/g/…). The page automatically updates approximately every 30 seconds, with times displayed in Taiwan Time. On the map, the blue dashed line represents the planned route, the pink solid line represents the reported track, the green dot marks the starting point, and the pink circle marks the most recently reported location. If the climber shared planned points, colored dots also appear on the map: red for hazard/retreat points, orange for huts/camps, blue for water, purple for summits, and gray for others. Tap one to see its name.

Nearby place names: When a reported location is near one of the climber's planned points, or near a hut, trailhead, water source, saddle, or peak built into the offline map, its card shows 'Near ○○ (about N m)'. Your phone matches this from the GPS position. GPS can be off by tens of meters, so the page only says 'near' and does not claim the climber is exactly there.

Trip timeline: Above the list, the 'Trip timeline' groups consecutive reports near the same place into one stop. A place reported only once is 'Arrived' (huts, camps, trailheads, planned points) or 'Passed' (water, peaks); reports at the same place for 15 minutes or more become 'Stayed', with the approximate time. Times are report times, so the real stay may have been longer. If the latest stop also holds the latest report, it is marked 'Latest report is still near here'. Tap a stop to find it on the map.

Slope colors and direction of travel: The 'Slope' button at the top right of the map (off by default) colors the reported track by slope: orange-red is uphill and blue is downhill, and the deeper the color the steeper the climb or descent. Flat stretches and stretches without altitude stay orange, and a legend sits at the bottom left. When you turn it on, the track draws itself from the start to the latest position in about 2.5 seconds, then small white arrows along the line show the direction of travel. The line gets wider as you zoom in, and the arrows only become easy to read once you are zoomed in. Slope comes from the altitude the climber's phone reported by GPS, so treat the colors as a guide when the altitude is off.
