Summary. X-Nova helps you spot fast-rising posts on X (Twitter) and draft a reply. Almost everything runs locally in your browser. We only send data to our server when you (1) activate a license or (2) tap the AI reply button — and even then, only what that feature needs. We never auto-post on your behalf, never sell your data, and show no ads.
1.Who we are
This extension ("X-Nova", "we") is operated by the X-Nova developer. This policy explains what data the extension accesses, what leaves your device, and why.
2.Data processed only on your device (never sent to us)
- Post metrics from your own X session. While you browse X/Twitter, the extension reads the data your logged-in browser already loads (a post's view count, timestamp, author handle and text) to calculate "velocity" and acceleration, draw on-timeline badges, and show a side panel. This calculation happens entirely in your browser. We do not use X's official API and do not receive this data.
- Your settings. Watched accounts and keywords, sensitivity, filter options, custom block words, language and toggles are stored locally via
chrome.storage.local.
- A random device ID and (after activation) a session token are stored locally to keep you signed in.
No automated actions. X-Nova never posts, replies, likes, or follows for you. The AI feature only produces a draft that you review and post yourself.
3.Data sent to our server — only for these features
- License activation & account status. When you paste a license key, we send the license key and your device ID to our backend to validate the license and return your plan, status and remaining credits.
- Trial registration. When you start a free trial, we send only your device ID to record the trial start date. No personal data is required.
- AI reply. When you tap the AI button on a specific post, we send that post's text and author handle to our backend, which forwards it to an AI model provider to generate a short reply draft.
4.Third-party processors
- Cloudflare — hosts our backend and database.
- AI model provider (e.g. MiniMax / DeepSeek) — receives the post text you chose, solely to generate your reply draft.
- Creem — handles payment and license keys.
5.Retention, your rights, and security
Local data stays on your device until you clear it or remove the extension. Account and usage records on our backend are kept while your account is active and deleted on request. Contact: wolfren98@gmail.com
