Privacy

declarativeNetRequest — Blocks sites using declarative rules. Does not read page content.
storage.sync — Saves your blocklist, timer state and settings in Chrome/Edge sync storage, so they follow your browser account. No data is sent to our servers.
alarms — Manages temp bypass timers. No background tracking.
Uses activeTab + <all_urls> for blocking rules only. License verification connects to api.annmax1983.com on activation and for periodic re-validation (at most once every 2 hours).
Password (optional) — stored only as a salted hash in local storage on this device. Never uploaded; forgotten passwords cannot be recovered.
