How NEBULA handles your data

Last updated 7 September 2026 · Applies to the NEBULA Chrome extension, all versions

The short version: everything NEBULA stores — your simulated wallet balance, trade history, and settings — lives only in your own browser. Nothing is sent to a NEBULA server, because no such server exists. The only network traffic NEBULA generates is fetching public, anonymous market-price data.

01 What NEBULA is for

NEBULA overlays a simulated trading panel on live Axiom (axiom.trade) and Dexscreener (dexscreener.com) token pages, so you can practice buying and selling real, live-priced memecoins against a fake balance — no wallet connection, no real funds, ever. Every simulated trade is logged to a local trade journal and performance dashboard inside the extension.

02 What we collect

The table below follows the same categories Chrome's Web Store asks every extension to disclose. NEBULA collects exactly one of them, and only to the extent its core feature requires.

Personally identifiable infoNot collected

Financial / payment infoNot collected

Authentication infoNot collected

Health informationNot collected

Personal communicationsNot collected

LocationNot collected

Web historyNot collected

User activityNot collected

Website content, in NEBULA's case, means the token symbol, price, market cap, and logo image that the extension reads directly off the Axiom or Dexscreener page you're already viewing — the same information visible on your screen. This is read purely to build that token's simulated trading panel and journal entry. It is processed on your device and saved to your device; it is never transmitted to NEBULA or any third party.

NEBULA does not have user accounts, does not use analytics or telemetry, does not log keystrokes, clicks, or scrolling, and does not track which sites you visit outside of the Axiom/Dexscreener pages it operates on.

03 Where your data lives

Your settings, simulated wallet balances, and full trade history are stored locally in your browser, using chrome.storage.local and IndexedDB — the same on-device storage every browser makes available to extensions. Nothing leaves your device as part of normal use.

Uninstalling NEBULA, or clearing the extension's site data from Chrome's settings, permanently deletes this data. NEBULA has no server-side copy to delete, because it has no server.

04 Network requests NEBULA makes

To simulate trades at real prices, NEBULA fetches public, anonymous market data from a small set of third-party price APIs. These requests contain a token address or symbol only — never anything about you, your device, or your browsing.

api.dexscreener.com, dexscreener.com — live token price and market data
api.geckoterminal.com — trending token data
api.coingecko.com — SOL/ETH reference pricing
axiomtrading-v2.axiom-cdn.io, axiomtrading-eth-v2.axiom-cdn.io — token logo images, sourced from Axiom's own public CDN

None of these services are told who you are. NEBULA does not attach any identifier, account, or session to these requests beyond what any ordinary web request already includes (your IP address, handled by each service under its own policy — NEBULA does not read or store it).

05 Our commitments

We do not sell or transfer user data to third parties.
We do not use or transfer user data for any purpose unrelated to NEBULA's single purpose — simulated memecoin trading practice.
We do not use or transfer user data to determine creditworthiness or for any lending purpose.

06 Changes to this policy

If NEBULA's data practices ever change, this page will be updated and the "last updated" date above will change accordingly. Continued use of the extension after an update constitutes acceptance of the revised policy.
