Your X connection
When you connect through the NexGen extension, we save your X browser session on our server so NexGen can send the replies you request from Telegram. This includes authentication cookies and session credentials. These details can provide access to your X account. This connection uses your browser session; it is not official X OAuth.
Information we process
We store your Telegram user/chat identifier, linked X session, account username when available, connection time, plan and daily usage. The extension may also collect your browser user-agent and account country or region information when available. We process post links and reply text from your Telegram commands to carry out your requests. Operational logs may contain activity, errors and reply content.
How information is used
We use this information to link your account, send requested replies, display your connection, apply your plan limits and maintain the service. Your connection is associated with your own private Telegram chat. Session details are not displayed in public pages or bot messages.
Payments
When checkout is enabled, we process your plan, invoice identifier, token amount, network, transaction hash, payment status and subscription expiry, linked to your Telegram user ID. Blockchain transfers are public and may reveal wallet addresses. We read transactions through blockchain RPC providers. We do not request or store wallet private keys, recovery phrases or payment-card details. Payment records may be retained for accounting and prevention of duplicate credit.
Security
We use HTTPS when the extension sends your X session to NexGen and restrict access to the server's session database. Saved X session credentials are encrypted at rest in the active server database and retained database backups. Encryption keys are kept in the private server environment, outside the database. No online service can guarantee absolute security.
Limited use
NexGen uses data received through the extension only to provide or improve the described account connection and reply features. We do not sell this data or use it for personalized advertising. Transfers are limited to delivering the service through our hosting and service providers, protecting security, complying with applicable law, or with your consent. Human access is limited to your explicit consent, security investigations, legal requirements or aggregated information permitted by the Chrome Web Store Limited Use requirements.
Post fetching and AI drafts
When you request a post preview or AI draft, NexGen fetches public post content through FxTwitter, VxTwitter, or X as a fallback. These services receive the requested post identifier or link; we do not send your X session credentials to them. AI drafts use Groq or Google Gemini, which receive the fetched post text and generation instructions. Your X session cookies and Telegram identifiers are not included in AI requests. Individual AI drafts are sent to your Telegram chat for review. In the button-based batch flow, selecting Run explicitly requests automatic generation and publication of replies to your supplied post links, at your selected delay (minimum 10 seconds). You can stop a running batch; an already submitted reply may still complete. Uploaded session files must contain post links, not account credentials. Reply posting limits apply when you request publication.
Service providers
Telegram handles your bot messages, X handles your account and posts, and Cloudflare routes requests to our hosting server. These providers process information under their own policies. NexGen does not use advertising trackers or analytics scripts on this website.
Retention and disconnecting
One X account is linked per Telegram user. Reconnect refreshes or replaces the current connection; simultaneous linked accounts are not supported. Standard allows three account replacements per calendar month (IST); refreshing the same account does not count. Self-service Disconnect is not available. Contact [email protected] to request removal of your account data. Reset setup in the extension clears local setup; it does not disconnect the server account. Plan and daily usage records remain for quota enforcement, and historical logs and backups may retain older information.
Your choice
Connect only an X account you control. You can stop using NexGen at any time and contact [email protected] to request deletion of your saved account data. Telegram and X may separately retain messages, posts and account activity.
