Cookie Policy
Last Updated: May 23, 2026. This policy explains how DataFuse uses cookies and similar tracking technologies when you browse or log into our dashboard.
1. What Are Cookies?
Cookies are small text files stored on your computer or mobile device by websites that you visit. They are widely used to make websites work, or work more efficiently, as well as to provide analytics data to the site owners.
In addition to HTTP cookies, we may utilize similar browser-storage elements such as HTML5 LocalStorage and SessionStorage to retain active user authentication tokens and dark mode preferences.
2. How We Use Cookies
DataFuse leverages cookies and local storage to:
- Identify you when you log into your developer workspace console.
- Preserve your chosen design theme (e.g. Light or Dark mode setting).
- Secure payments and prevent credit card fraud on Stripe checkout overlays.
- Analyze system performance, telemetry, and error rates via Datadog.
We do not use any third-party tracking pixels or marketing cookies designed to track your activity across unrelated websites.
3. Types of Cookies We Use
We categorize our cookies and local storage into three distinct categories:
- Strictly Necessary Cookies: These cookies are critical to render our services and let you browse our site. They cannot be turned off in our settings, as they enable basic functions like login sessions, billing, and CSRF protection tokens.
- Preference Cookies: These enable the website to remember details that change how the website behaves or looks, such as your chosen color scheme theme or active sidebar collapsed status.
- Performance & Telemetry: These help us understand how developers interact with our integration portal. They collect aggregate error and usage rates so that we can patch bottlenecks.
4. Detailed Cookie Inventory
The following inventory details the exact cookies and local storage variables set by DataFuse:
| Cookie / Key | Provider | Type | Retention |
|---|---|---|---|
| nuxt-color-mode | DataFuse | Preference | Persistent |
| __session | DataFuse | Strictly Necessary (Auth) | Session |
| __stripe_mid | Stripe | Necessary (Billing Fraud) | 1 year |
| datadog-rum-* | Datadog | Performance / Telemetry | Session |
5. Managing Your Preferences
Most modern web browsers allow you to manage and block cookies through their standard preference menus. Be informed that if you disable essential cookies entirely, some parts of the DataFuse dashboard (such as workspace authentication and billing invoices) may cease to operate correctly.
To adjust your cookie preferences inside the browser:
- Google Chrome: Go to Settings ➔ Privacy and Security ➔ Cookies and other site data.
- Mozilla Firefox: Go to Preferences ➔ Privacy & Security ➔ Cookies and Site Data.
- Apple Safari: Go to Preferences ➔ Privacy ➔ Manage Website Data.
6. Policy Updates
We may modify this Cookie Policy from time to time to adapt to billing upgrades or subprocessor shifts. We encourage you to visit this page periodically to remain informed about our utilization of tracking technologies.
