About this extension
Ark Sentinel keeps an eye on your Lost Ark characters published on lostark.bible and warns you as soon as a new combat log mentions them.

How it works
  • Add a character by pasting its page address (for example https://lostark.bible/character/CE/YourCharacter): it is taken into account immediately and a first check starts.
  • The extension then checks at a regular interval (5 to 120 minutes, 15 by default) and compares the logs with those already known.
  • Every new log triggers a clickable system notification that opens the log directly, plus a golden counter on the toolbar icon.

In the popup
  • The latest fights of each character: boss, difficulty, duration, DPS, possible death and age.
  • NEW tag on unread logs, several characters handled through tabs.

Settings
  • Per-boss alert filter, built automatically from the bosses actually met in your logs.
  • Three read strategies (site data, HTML, render tab) to survive site evolutions.
  • Interface in French, English and German, with a visual mood inspired by Lost Ark.

Privacy

No collection at all: the character list, the settings and the logs stay stored locally in your browser. The only network requests go to lostark.bible, with your own session (your private logs are therefore visible if you are signed in on the site).
