wtf is lynkco-auto-checkin?

This project automates the daily check-in feature inside the Lynk and Co car brand's mobile app. Many car apps give users points or rewards for opening the app and tapping a check-in button every day, and this tool does that automatically instead of requiring you to remember to do it yourself. The tool runs inside a Docker container and performs three things on a schedule: it checks in once a day at a random time in an early morning window, it automatically shares an article each day to collect extra points, and it refreshes its own login token every time it runs so that your access never expires as long as the container keeps running daily. Results are sent to you through a push notification service called Bark, which is an iOS app for receiving custom alerts, though the project also supports sending notifications through WeCom, DingTalk, and Feishu, which are workplace chat tools common in China. To set it up, you first need to capture your own login token from the Lynk and Co app on your phone using a network debugging tool, log out and back into the app while capturing traffic, then copy the token values out of the response. Those values go into environment variables when you start the Docker container, either with a single docker run command or with Docker Compose. The token cache is saved to a file inside a mounted volume so it survives container restarts. The README notes that logging out of the app on your phone will break the refresh token, and that the setup only needs a fresh token if the container has been stopped for more than 30 days. The project author is explicit that this is meant for personal learning and use, not for abuse of the service. No license is stated in the README.
