Cookie Policy | StackSpeed

1. What Are Cookies

Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work properly, to remember your preferences, and to provide website owners with analytical information about how their site is used.

StackSpeed uses first-party cookies (set by stackspeed.dev) and third-party cookies (set by services we use, such as Google Analytics). We do not use cookies for advertising or cross-site tracking.

2. Types of Cookies We Use

EssentialAuthentication & Session

These cookies are strictly necessary for the service to function. They manage your authentication session via Supabase Auth. Without these cookies, you cannot sign in. Because they are essential, they cannot be disabled while you are using the signed-in features of StackSpeed.

AnalyticsGoogle Analytics 4 (via GTM)

We use Google Analytics 4, deployed via Google Tag Manager, to understand how visitors use the site — which pages they visit, how long they stay, and where they come from. This helps us improve the product. IP addresses are anonymised before transmission to Google. We do not use GA4 data for advertising targeting.

You can opt out of Google Analytics across all sites using the Google Analytics Opt-out Browser Add-on.

PreferencesUI Preferences

These cookies remember your display and UI preferences (such as layout density) so you do not have to reconfigure them on each visit. They do not collect personal data and are stored only on your device.

5. How to Control Cookies

Browser settings: All modern browsers allow you to view, delete, and block cookies. Blocking essential cookies will prevent you from signing in to StackSpeed. Instructions for common browsers:

Google Analytics opt-out: You can prevent Google Analytics from collecting your data by installing the Google Analytics Opt-out Browser Add-on.

Do Not Track: Some browsers transmit a “Do Not Track” signal. We currently do not alter our data collection in response to this signal, but we will review this position as standards evolve.

6. Changes to This Policy

We may update this Cookie Policy to reflect changes in the cookies we use or applicable law. When we make material changes, we will update the “Last updated” date at the top of this page.
