Privacy Policy — Heal Reminder

Last updated: 2026-04-12

Heal Reminder does not collect, transmit, or share any user data.

Data Storage:
- Your reminder settings (intervals, toggles, quiet hours) are stored locally on your device using Chrome's built-in storage API (chrome.storage.sync).
- If you are signed into Chrome, your settings sync across your devices through Google's own sync infrastructure. Heal Reminder does not operate or control this sync — it is a standard Chrome feature.
- Recent action timestamps (e.g., "last completed hydration reminder") are stored in chrome.storage.local and never leave your device.

Network Activity:
- Heal Reminder makes zero external network requests.
- No analytics, telemetry, tracking, or advertising is included.
- No third-party services or SDKs are used at runtime.

Content Script:
- Heal Reminder injects a content script into web pages (http/https) solely to display toast-style reminder notifications.
- The content script does not read, access, or modify any page content, DOM elements, cookies, or user data.
- The notification is rendered inside an isolated Shadow DOM element and is removed after dismissal.

Permissions:
- alarms: Schedule recurring reminder timers
- notifications: Fallback native notifications when the content script is unavailable
- storage: Save your preferences locally
