Cookie Policy
Last updated: February 16, 2026
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 logged in, and understand how you use the service. We also use browser local storage for certain preferences.
2. How we use cookies
Grix uses cookies and local storage for the following purposes:
Essential cookies (always active)
These are required for the application to function. They cannot be disabled.
| Cookie / Storage | Purpose | Duration |
|---|---|---|
sb-*-auth-token | Authentication session (Supabase). Keeps you logged in securely. | 1 hour (auto-refreshed) |
sb-*-auth-token-code-verifier | PKCE code verifier for secure OAuth flows. | Session |
NEXT_LOCALE | Stores your language preference (English or French). | 1 year |
cookie-consent | Records your cookie preferences to avoid showing the banner repeatedly. | 1 year |
Local storage (essential)
These use browser local storage rather than cookies, but serve a similar purpose:
| Key | Purpose | Duration |
|---|---|---|
theme | Stores your dark/light mode preference. | Persistent |
sidebar-collapsed | Remembers whether you collapsed the sidebar. | Persistent |
Analytics cookies (optional)
Help us understand how visitors interact with Grix so we can improve the product. These are only set with your explicit consent.
| Cookie | Purpose | Duration |
|---|---|---|
_va_* | Vercel Analytics — anonymized page views and performance metrics. | Session |
Marketing cookies (optional)
Used to measure the effectiveness of our advertising campaigns and attribute signups to the correct ad channel. Only loaded with your explicit consent via the "Marketing" toggle in the cookie banner.
| Cookie | Provider | Purpose | Expiry |
|---|---|---|---|
_gcl_aw | Google Ads | Stores the Google click identifier (gclid) to attribute conversions to Google Ads campaigns. | 90 days |
_fbp | Meta (Facebook) | Identifies browsers for conversion measurement across Meta ads (Facebook, Instagram). | 90 days |
_fbc | Meta (Facebook) | Stores the Meta click identifier (fbclid) to match ad clicks to conversions. | 90 days |
When marketing cookies are accepted, we also use first-party cookies to store ad click identifiers (gclid, fbclid) from your original visit. These are used exclusively to report accurate conversion data to Google Ads and Meta. Your email address is hashed (SHA-256) before any transmission to ad platforms and is never shared in plaintext.
3. Managing your preferences
When you first visit Grix, a cookie banner lets you accept or customize your preferences. You can change your choices at any time from the cookie settings link in the footer of any page.
You can also manage cookies through your browser settings. Note that blocking essential cookies will prevent the application from functioning correctly (you will not be able to stay logged in).
4. Third-party cookies
We minimize third-party cookies. Our authentication provider (Supabase) sets first-party cookies for login functionality. Our hosting provider (Vercel) may set analytics cookies only with your consent. When you accept marketing cookies, Google Ads (gtag.js) and Meta Pixel (fbevents.js) scripts are loaded to measure advertising performance — these are only activated with your explicit consent.
5. Do Not Track
Some browsers send a "Do Not Track" (DNT) signal. Grix respects this signal — when DNT is enabled, analytics cookies are not loaded regardless of your cookie consent preferences.
6. Legal basis for cookies
Essential cookies are processed under our legitimate interest in providing a functional service. Analytics and marketing cookies are processed based on your explicit consent, which you can withdraw at any time.
7. Updates
We may update this Cookie Policy as our use of cookies evolves. Changes will be reflected on this page with an updated date. If we introduce new non-essential cookies, we will request your consent again.
