When you sign in with Google, we receive and store the following information from your Google account:
This data is stored in a Cloudflare D1 database and is used solely to identify your account, manage your subscription, and enforce usage limits.
If you upgrade to a paid plan, your Stripe customer ID and subscription status are stored alongside your account record. All payment processing is handled by Stripe. We never receive or store your card number or banking details.
We track a daily count of AI generation requests per user to enforce plan limits.
When you use the AI reply feature, the tweet text and your pre-prompt are sent to our Cloudflare Worker, which proxies the request to OpenAI for processing. No X credentials are included in this request, and the generated text is not stored on our servers.
The extension runs entirely in your browser and uses your existing X session to perform actions like following users or looking up public profile information. Your X credentials and session cookies never leave your browser and are never sent to our servers.
The extension stores preferences (tone, pre-prompt), follow history, and your authentication token in your browser's local storage via chrome.storage.local. This data never leaves your device.
You can sign out at any time, which clears all locally stored data. To request deletion of your server-side account data, contact us using the details below.
