Privacy Policy

This is a translation for convenience. If it differs from the Korean version, the Korean version applies.

This policy applies to this site (i6020345.com) and the apps I’ve made, Bluetooth Battery Bar and Junction. None of the three has user sign-up, and I haven’t added analytics tools or ads to any of them. ONLINESUBWAY is a separate service and follows the policy at onlinesubway.com.

Website

  • This site doesn’t use cookies, analytics tools, or ads.
  • Fonts are loaded from Google Fonts. In the process, connection information such as your browser’s IP address is passed to Google.
  • What you write in the letter form isn’t sent to this site. The form only opens a new email with your message filled in, and only the emails you actually send yourself reach my inbox.
  • Emails I receive (name, email address, and content) are used only to reply, and aren’t provided to anyone else.

Bluetooth Battery Bar

  • The app doesn’t collect, store, transmit, or share personal information.
  • It makes no network requests at all, and no data of any kind leaves your Mac.
  • Battery levels are read from macOS and kept only in memory while the app is running.
  • Your settings for whether alerts are on, the alert threshold, language, and launch at login are stored in UserDefaults on your Mac, and are removed when you delete the app.
  • Low battery alerts are local notifications created on your Mac, and don’t go through any server.

Junction

  • There are no accounts, and the app doesn’t store sign-in information or tokens.
  • It doesn’t send file contents or file lists to me. The index used for fast search (metadata such as file names and paths) is stored only on your Mac, in ~/Library/Application Support/Junction/Index.
  • Folder access permissions are used only to show and search your files. For cloud folders, it reads the folders that each service’s desktop app creates, and syncing with that service is covered by that service’s policy.
  • It connects to GitHub to check for updates (using the open-source Sparkle). When it does, connection information such as your IP address and the app version may be passed to GitHub. You can turn off automatic checks in the app’s settings.
  • Settings such as sidebar items are saved on your Mac.

Questions and deletion requests

If you’d like to see or delete an email you sent, or if you have any questions, let me know at ko.leejk@gmail.com. The person responsible is Jungkyu Lee. If this policy changes, I’ll update the revision date on this page too.
