Privacy

Last updated: October 26, 2026

The short version

DEJAVU does not collect, send or sell any data. Everything you save stays in your own browser.

What the extension stores

• Your notes, labels and blacklist for X accounts and Solana addresses.
• Addresses you came across, with when you first saw them and who posted them.
• Your settings, such as whether blacklisted posts are hidden or dimmed.

This is stored with chrome.storage.local on your device only. You can export it, import it or delete it from the extension popup. Removing the extension deletes it.

What the extension does not do

• It makes no network requests and has no server.
• It never asks for or reads a wallet, a private key, a seed phrase or a signature.
• It has no analytics, no tracking and no ads.
• It only runs on x.com, twitter.com, pump.fun and gmgn.ai, and only reads what is shown on those pages.

This website

dejavu.tools is a static site. It sets no cookies and loads no trackers or third-party scripts. The demo on the home page saves its example notes in your browser's local storage for that page only.
