The short version. Fomo Guard sends token contract addresses to public
blockchain security services so it can check a token for rug vectors. Nothing else
leaves your browser. There is no account, no analytics, no tracking, and no server
of ours. Your paper trades and settings are stored locally on your own device.
What the extension does
Fomo Guard adds a risk checklist and trade plan to token pages on fomo.family. It is
read-only: it never signs, submits, or initiates a transaction, and it has no access
to any wallet, private key, or seed phrase.
What leaves your browser
Exactly one kind of data, and only to check the safety of a token you are looking at:
The token's contract address and its chain identifier, sent to public
security services: RugCheck (Solana), GoPlus (EVM chains), and Blockscout
instances. These return contract facts such as mint and freeze authority,
honeypot indicators, liquidity-pool lock status, and holder concentration.
The same token or wallet address, sent to public blockchain RPC nodes to
read on-chain bytecode, which is how the extension confirms whether a
liquidity-pool holder is a contract or an ordinary wallet.
These requests contain the token address only. They do not include your identity,
your wallet address, your balances, your trades, or any account information. Those
third-party services receive the request from your browser and are governed by their
own privacy policies.
What stays on your device
The extension reads the fomo.family page you have open, including the data fomo's
own site loads to display it. That can include your positions and average entry
price, which the extension uses to show numbers based on your actual holding rather
than a hypothetical one. All of this is processed locally and none of it is
transmitted anywhere.
Stored locally in your browser (Chrome's storage.local), and nowhere else:
Your paper trades and the paper-trading record
A log of the verdicts the extension produced, used to measure its own accuracy
Interface preferences, such as whether a panel is collapsed
You can delete all of it at any time by removing the extension, or by clearing the
extension's data in Chrome. There is no copy anywhere else, because there is nowhere
else: this project runs no server and no database.
What we do not do
No analytics, telemetry, crash reporting, advertising, or tracking of any kind
No accounts, no sign-in, no email collection
No selling, renting, or transferring of data to anybody
No use of any data for creditworthiness or lending purposes
No remotely hosted code: everything the extension runs ships inside the package
Children
Fomo Guard is not directed at children and is not intended for anyone under 18.
Changes

the extension's release notes.
