Privacy Policy

How Clustell and Clustell for Chrome handle account data, browser permissions, and local storage.

Effective Date: November 2026Applies to clustell.xyz & Clustell for Chrome

1. Core Security & Read-Only Guarantee

Clustell is a market intelligence platform. Neither clustell.xyz nor the Clustell for Chrome browser extension ever accesses private keys, seed phrases, wallet signing permissions without your explicit transaction prompt on the web app, X account passwords, direct messages, or browsing history on unrelated websites. We never sell or rent user data to third parties.

2. Clustell for Chrome Extension Permissions

The Clustell browser extension uses strict, minimum-scope Chrome Manifest V3 permissions solely to display market intelligence alongside supported pages:

Local Storage (`storage`)

Stores your optional 30-day Clustell device session token, display mode preference (Side Panel vs. Popup), and a short-lived local KOL badge cache so scrolling X makes zero background queries per post.

Side Panel (`sidePanel`)

Renders asset Watch Scores, Echo Chambers, KOL call ledgers, and Daily Digests in Chrome's native docked side panel or toolbar popup when opened by you.

Scoped Host Access

Runs strictly on X (`x.com`) and supported crypto trading terminals (DEXScreener, Birdeye, Pump.fun, GMGN, Jupiter, GeckoTerminal, BullX, Photon, Axiom, Padre, Defined.fi) plus `clustell.xyz` for account sync. Non-crypto websites are ignored locally in the browser and never sent to our servers.

3. Account Information, Alerts & Payments

  • Authentication: When you sign in via Privy, we store your account identifier, optional display name, email address (if you sign in with email/Google or enable email alerts), and public Solana wallet address (if connected for payments).
  • Saved Collections: Your Watchlists, Portfolio holdings/cost-basis entries, saved Echo Chambers, and notification channel preferences (email or Telegram chat ID) are stored privately in our database to sync across your web and extension sessions.
  • On-Chain Payments: Subscriptions and credit top-ups settle on the public Solana blockchain in USDC. Clustell records public transaction signatures and entitlement balances for accounting and access control.

4. Revoking Access & Contact

You can revoke any connected browser extension session immediately from your Profile Settings or uninstall the extension at any time to clear all local extension storage. To request account data export or deletion, or for any privacy questions, contact editor@clustell.xyz.
