Cookies & Local Storage Policy
Last updated: March 5, 2026
Let's keep this simple: iziDo barely uses cookies. Seriously. We're a Chrome extension that believes in respecting your browser, not cluttering it with trackers. This policy explains what we do use and why.

3. Storage in the Chrome Extension
The iziDo Chrome extension uses chrome.storage.local (not traditional cookies) to store data on
your device. Here's exactly what we store and why:
| Storage Key | What It Stores | Why | Duration |
|---|---|---|---|
izido-auth |
Authentication state (user ID, session tokens, profile data) | Keeping you signed in so you don't have to log in every time | Until you sign out or tokens expire |
taptapSettings |
Notification preferences (enabled/disabled, quiet hours, badge alerts, weekend mode) | Remembering how you want to be notified | Until you change them or uninstall |
taptap_nudged_tasks |
Map of task IDs to nudge timestamps | Tracking which tasks have active nudges to show the right UI indicators | Until nudges expire or are dismissed |
izido-rate-limits |
Login attempt counters and timestamps | Security: preventing brute-force attacks on your account | 5-minute rolling window, auto-expires |
3.1 Supabase Session Tokens
When using sync mode, Supabase's authentication library stores session data locally:
- Access token (JWT) — a short-lived token that authenticates your API requests. Automatically refreshed.
- Refresh token — a longer-lived token used to generate new access tokens without re-entering your password.
These tokens are stored in chrome.storage.local and are only sent to Supabase servers over encrypted (HTTPS) connections.
3.2 What We Don't Store
- No browsing history or visited URLs
- No web page content
- No advertising identifiers
- No cross-site tracking data
- No fingerprinting data
4. Third-Party Cookies & Storage
4.1 Extension Context
The iziDo extension communicates with Supabase (*.supabase.co) for
authentication, data sync, and real-time features. Supabase may set cookies in its own domain context for
session management, but these are not accessible to iziDo or any other website — they're
sandboxed by your browser's security model.
4.2 No Analytics or Tracking Cookies
We do not use any of the following (on either the website or the extension):
- Google Analytics
- Facebook Pixel
- Mixpanel, Amplitude, or any event tracking service
- Hotjar, FullStory, or any session recording tool
- Any advertising cookies or retargeting pixels
- Any fingerprinting or cross-device tracking
6. Do Not Track (DNT) Signals
We respect Do Not Track signals. But honestly, it doesn't change much for us since we don't track you in the first place. There are no analytics, no tracking pixels, and no behavioral profiling to disable.
Similarly, we honor the Global Privacy Control (GPC) signal. Again, we don't sell or share personal data for targeted advertising, so GPC doesn't change our behavior — we're already doing the right thing.
7. Changes to This Policy
If we change what cookies or storage we use, we'll update this page and the "Last updated" date. For significant changes (like adding analytics — which we have no plans to do), we'll provide notice through the extension.
