LENS ("we", "our", or "the extension") is a browser extension that displays publicly available on-chain intelligence directly on Twitter/X profiles. This Privacy Policy explains what data the extension accesses and how it is handled. Your privacy matters to us, and we have built LENS to be as privacy-respecting as possible.
Summary: LENS reads public information from the X profile you are viewing, queries public blockchain and archive data, and shows the results to you. We do not sell your data, we do not run ads, and the extension does not collect or transmit your personal browsing history.
1. Information the extension accesses
When you visit a Twitter/X profile, LENS reads the following publicly visible information from that page in order to function:
The public username (handle) of the profile you are viewing
Public wallet addresses or contract addresses mentioned in the profile bio
Public GitHub links mentioned in the profile bio
This information is used solely to query public data sources and display intelligence to you on that same page.
2. Data sources we query
To generate the intelligence shown in the panel, LENS sends the public identifiers above to the following services:
LENS backend (lnsx.io) to look up indexed public Bankrbot token launches, fee data, holder statistics on the Base blockchain, and which curated high-signal accounts follow the profile (Smart Follower). For the Smart Follower lookup, only the public handle of the profile you are viewing is sent. It is not linked to your identity.
Public blockchain data covering on-chain activity on Base mainnet via standard RPC providers.
memory.lol, a public archive used to show historical public usernames.
GitHub public API, only when a GitHub link is present in the profile bio.
AI provider (Venice), only when you use the Ask AI feature in the documentation. See section 4 below for full details.
All of these queries use publicly available data only. LENS does not access private messages, private account data, or any information that is not publicly visible.
3. Data stored on your device
LENS uses your browser's local storage to save:
Your settings and preferences (e.g. which features are enabled)
Your watchlist of pinned profiles
A local history of profiles you have scanned, shown only in the extension popup
Optional API keys you choose to enter
This data is stored locally on your device only. It is not transmitted to us and is never sold or shared. You can clear it at any time from the extension or by removing the extension.
4. Ask AI (documentation assistant)
Our documentation pages include an optional Ask AI feature. It only runs when you type a question and submit it. When you do:
The text of your question is sent to our backend, which forwards it to a third-party AI provider (Venice) to generate an answer.
The AI answers using the public content of our own documentation as context. It does not have access to your wallet, your watchlist, your scan history, or any other data stored on your device.
We do not attach your name or identity to the question, and we do not store your questions to build a profile of you.
Please avoid typing sensitive personal information into the Ask AI box, since the question text leaves your device to be answered.
If you never use the Ask AI feature, no question text is ever sent anywhere.
5. MCP and agent access
LENS offers a public MCP (Model Context Protocol) endpoint that lets AI agents and developer tools request the same public on-chain verdicts that the extension shows. This is an opt-in developer feature:
It only runs when you, or a tool you have set up, sends a request to the endpoint.
It returns the same public intelligence (verdicts, trust scores, public token and wallet data) described elsewhere in this policy.
It does not read your local watchlist, settings, or scan history, and it is not connected to your personal identity.
6. Information we do not collect
We do not collect your name, email, or personal identity.
We do not track your general browsing history.
We do not sell, rent, or share your data with advertisers.
We do not display advertisements.
We do not store your Ask AI questions to profile or identify you.
7. Permissions
The extension requests the following permissions for the reasons described:
Access to x.com / twitter.com to read the public profile you are viewing and inject the intelligence panel.
Storage to save your settings, watchlist, and scan history locally.
Access to our data sources (lnsx.io, blockchain RPC, GitHub, memory.lol, and the Venice AI provider for Ask AI) to fetch the public data and answers shown to you.
8. Third-party services
When you click links in the panel (for example to BaseScan, DexScreener, or Bankrbot), you leave the extension and visit those third-party websites, which have their own privacy policies. The Ask AI feature also relies on a third-party AI provider (Venice) to generate answers. We are not responsible for the practices of these third parties.
9. Children
LENS is not directed to individuals under the age of 18 and we do not knowingly collect data from children.
10. Changes to this policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the extension after changes constitutes acceptance of the updated policy.
