Privacy Policy
Last updated: July 15, 2026 · Applies to: Memefolio Chrome Extension & memefolio.wtf
Memefolio is a Chrome extension that overlays public wallet data from Solana, Ethereum, Base and Robinhood Chain on X profiles. This policy explains what we collect and why. We collect only the minimum needed to run the service, and we do not run ads or track your browsing.
By installing the extension or registering on memefolio.wtf, you confirm you have read and understood this policy.
// What you agree to when you register
Registration is entirely opt-in. By connecting your X account and linking one or more wallets you explicitly authorise:
- Your X username will be stored in our database and used as a lookup key by the extension.
- Your public wallet addresses, meaning your Solana wallet and any EVM addresses you add (Ethereum, Base, Robinhood Chain), will be stored and used to query your live on-chain holdings.
- Your token holdings and approximate USD value will be visible to anyone browsing X with Memefolio installed who visits your profile.
- This data stays public until you request deletion at support@memefolio.wtf.
- You confirm that you are comfortable associating it publicly with your X identity.
Blockchain data is public by nature. Memefolio displays data already visible to anyone on-chain. We do not create new exposure, we surface what already exists.
01
🧩Extension users
The extension does not collect, transmit or store any personal data about you as a viewer.
- It reads the username of the X profile you are viewing to run a lookup. This never leaves your device in association with your identity.
- Portfolio data is cached in
chrome.storage.local on your device for up to 30 minutes. It is never sent to us.
- Your overlay on/off preference is stored locally on your device only.
We do not collect your browsing history, your X credentials, or anything about who you are.
02
📝Registered users
If you register, we store your X username, any public wallet addresses you link (your Solana wallet and/or EVM addresses on Ethereum, Base and Robinhood Chain) and the timestamp of registration.
We do not collect email addresses, passwords, phone numbers or payment information. We never request write access to your X account.

⚙️How we use your data
Registered data is used for one purpose: allowing the Memefolio extension to display your on-chain portfolio, across every chain you link, to users who view your X profile.
