This Cookie Policy explains how YouTube Dubbing ("Company," "we," "us," and "our") uses cookies and similar storage technologies (including Local Storage, Session Storage, and IndexedDB) to recognize you when you visit our website at https://ytdubbing.com ("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, Session Storage, and IndexedDB (via HTML5 Web Storage and the Chrome Storage API), which allow structured configuration, authentication state, and media cache 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 video dubbing credit quotas, and remember your playback configuration (such as your preferred target translation language, neural voice persona, audio ducking volume level, dubbed voice loudness, and synchronized subtitle preferences). 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:
access_token & id_token (Local Storage): Secure JSON
Web Tokens (JWT) issued by Amazon Cognito. Essential to verify your identity, authorize access to
your member dashboard, validate your active subscription plan, and verify daily video credit allowances.youtube_dubbing_cookie_consent (Local Storage): Records your cookie
preferences so you are not repeatedly prompted on subsequent visits. Persistent until cleared.user_email_for_confirmation (Local Storage): Temporarily holds your
email during account registration to facilitate seamless email verification code confirmation.
Purged immediately upon successful confirmation.email_for_password_reset (Local Storage): Temporarily holds your email
address during the multi-step password reset workflow. Purged immediately upon password update.post_login_redirect (Session Storage): Temporarily preserves your intended
destination route (such as /dashboard) during login or registration workflows. Cleared immediately upon redirection.youtube_dubbing_just_logged_out (Session Storage): A transient security flag
preventing automated token re-validation immediately following an intentional user sign-out action.youtube_dubbing_challenge (Session Storage): A transient security flag used
when Amazon Cognito issues an administrative challenge (such as NEW_PASSWORD_REQUIRED)
to guide you through initial credential setup. Automatically cleared on tab close.When using the YouTube Dubbing Chrome extension, client-side storage and client-side database caches are used strictly to provide in-browser playback controls, prevent latency, and eliminate redundant server and AI synthesis queries:
youtube_dubber_user_settings (Chrome Local Storage): Remembers your customized
dubbing configuration across videos, including your chosen source language, target translation language, regional accent dialect,
selected neural voice model, original video volume ducking percentage, dubbed speech loudness, and subtitle display preferences (toggle state and font scaling).youtube_dubbing_tokens (Chrome Local Storage): Securely stores your synchronized
Cognito authentication tokens (idToken and accessToken) delivered via an offscreen synchronization bridge to authorize video dubbing sessions without requiring disruptive re-logins.youtube_dubbing_auth_time (Chrome Local Storage): Records the exact timestamp of token synchronization
to govern silent, proactive token renewals before expiration.cached_tts_endpoints & cached_tts_fallback_url (Chrome Local Storage): Locally caches
the active regional speech synthesis worker fleet (e.g., Stockholm, Ireland, Frankfurt) and fallback endpoints to guarantee zero-latency request dispatching and high service availability.YouTubeDubberCache — audio_cache (IndexedDB): Client-side storage of synthesized speech audio buffers (WAV data),
timelines, and sentence durations for up to 14 days. Enables instant, zero-delay replay of previously dubbed video segments in 0 milliseconds without re-synthesizing audio or deducting additional video credits.YouTubeDubberCache — translation_cache (IndexedDB): Client-side cache storing verified AI-streamed and machine-translated subtitle
sentences with precise timestamp boundaries. Eliminates redundant translation API calls on page reloads, ensuring instant subtitle and audio playback.__stripe_mid and __stripe_sid) necessary to securely process credit card
transactions and subscription checkouts.
