This Cookie Policy explains how Hyperdrive AI ("Hyperdrive", "Company," "we," "us," and "our") uses cookies and similar storage technologies (including Local Storage and Session Storage) to recognize you when you visit our website at https://hyperdriveai.app ("Website") and when you use our Google Chrome browser extension. It details what these technologies are, why we use them, and your rights to control them.
Cookies are small data files placed on your computer or mobile device when you visit a website. In addition to cookies, modern web applications and extensions use Local Storage and Session Storage (via HTML5 Web Storage and the Chrome Storage API), which allow structured configuration and authentication state to be saved directly on your device without transmitting unneeded data over every single HTTP request.
Cookies and storage items set directly by us are "first-party storage." Items placed by external services (such as Stripe for payments or Google for analytics) are "third-party cookies."
We use first- and third-party storage for essential operational reasons: to authenticate your Amazon Cognito account, securely process subscription payments with Stripe, prevent CSRF attacks, enforce generation quotas, and remember your playback configuration (such as your target duration slider, active preset, and subtitle positioning). We also utilize non-essential cookies for analytics and affiliate tracking, subject to your express consent under Google Consent Mode v2.
You have the right to accept or reject non-essential cookies. You can adjust your choices anytime by clicking "Cookie Settings" in our website footer or through the Cookie Preferences Center banner. Essential cookies and storage items cannot be rejected, as they are technically necessary to provide the Services.
We honor Global Privacy Control (GPC) and Do Not Track (DNT) signals sent by your browser. If GPC or DNT is detected, non-essential analytics and marketing cookies are automatically disabled without requiring manual adjustment.
These items are strictly necessary for core application functionality, user authentication, and billing security:
