Terms of use

1. Acceptance

Downloading, installing, or using Lên means you accept these terms and the privacy policy. If you do not agree, uninstall the app and stop using the website.

2. The service

Lên is a free tool to read routes, record GPS, use offline maps, and see mountain information in Vietnam. There is no subscription for people who hike. Porter, guide, and operator software are contact-only. They are not sold inside the app.

3. Not a professional guide

Sample routes and figures in Lên are illustrative. They are not a surveyed track unless the route page says otherwise. The map, GPS, and off-route warning can be wrong because of canopy, cliffs, a weak battery, or an old base map. You decide whether to go. Do not use Lên as your only tool in the mountains.

4. Safety and SOS

SOS shows 115, 112, 113, and 114 and your coordinates so you can call or send them yourself. Lên does not contact rescue for you, does not guarantee a signal, and is not an emergency service. Mountains can injure or kill. You are responsible for your health, equipment, the weather, and your decisions.

5. Accounts

An account is optional and is for people aged 16 or older. You keep the password secret. We may lock an account that posts false danger reports or harasses other people.

6. What you post

Reviews and condition reports must be true to the best of your knowledge. Do not post abuse, disguised ads, or information intended to put someone in danger. We may review, hide, or remove that content. You keep your words and give Lên permission to show them on the app and the website with the route.

7. Sponsors

The app shows at most five partner banners. A banner is never shown while you are recording or while SOS is open. Tapping a banner opens the partner’s site. Lên does not guarantee the partner’s goods.

8. What you may not do

• Track another person who has not agreed.
• Scrape the service, break the servers, or impersonate someone.
• Treat a sample route in the field as if it were a surveyed line.

9. App stores

If you downloaded Lên from Google Play, these terms are between you and the publisher of Lên, not Google. If you downloaded it from the App Store, Apple’s Licensed Application End User License Agreement still covers the software licence, and these terms also apply where they do not conflict. Apple is not responsible for the app, its content, maintenance, or support, and has no duty to handle a claim about the app. You also follow the rules of the store you downloaded from.

10. Liability, ending the terms, and law

The app is provided as it is. To the extent the law allows, Lên is not liable for getting lost, injury, lost gear, loss of signal, or a decision to continue from a sample route. Nothing here excludes liability the law does not allow to be excluded. You can stop using the app at any time and you can request account deletion. These terms follow the laws of Vietnam.
