Twellie — Cookie Policy

Last Updated: April 19, 2026

This Cookie Policy explains how Twellie, Inc. ("we," "us," or "Twellie") uses cookies and similar tracking technologies on our website and mobile apps. It supplements our Privacy Policy.

1. What Are Cookies?

Cookies are small text files stored on your device when you visit a website. They help the site remember your preferences, keep you signed in, and measure how the site is used. Similar technologies include:

Local storage / session storage (browser-based key-value stores);
Pixels / web beacons (tiny images used to record page loads);
Mobile SDK identifiers (used by Facebook App Events, Google Analytics for iOS/Android);
Advertising IDs (IDFA on iOS, AAID on Android).

In this Policy, "cookies" refers to all of the above unless we specify otherwise.

2. Cookie Categories

2.1 Strictly Necessary

These cookies are essential for the Service to function. They enable basic features like page navigation, authentication, and access to secure areas. They cannot be disabled.

`sb-<ref>-auth-token`	Supabase	Authentication session	1 hour (refreshed)
`__Secure-sb`	Supabase	Session-refresh handshake	Session
Session cookies	Twellie	CSRF protection, load balancing	Session

2.2 Functional

If you opt out of analytics, these cookies are not set, and no analytics events are sent.

2.4 Advertising / Targeting

`_fbp`	Meta (Facebook) Pixel	Conversion and remarketing	90 days

Opting out of advertising stops these pixels from firing.

3. Your Choices

Cookie banner: When you first visit twellie.com, a banner lets you Accept all, Reject non-essential, or Customize which categories load. Your choice is saved in the homeai_consent cookie for 12 months, then we ask again.
Change your choice anytime at https://twellie.com/cookie-preferences.
Browser settings let you block or clear cookies. Note: blocking Strictly Necessary cookies will break core features like signing in.
Global Privacy Control ("GPC"): We honor GPC. If your browser sends GPC, we treat it as a rejection of advertising cookies.
Mobile: Reset or limit ad tracking via iOS Settings → Privacy → Tracking, or Android Settings → Privacy → Ads.
Network-level opt-outs: Meta — https://www.facebook.com/help/568137493302217; Google Analytics — https://tools.google.com/dlpage/gaoptout.

4. Do Not Track

We do not currently respond to browser "Do Not Track" signals, which are not standardized across the industry. We do honor Global Privacy Control as described above.

5. Changes

We may update this Cookie Policy as we add/remove tools. Material changes will be announced at https://twellie.com/cookie-policy with a new "Last Updated" date. Continued use after changes constitutes acceptance.
