# Accounts, privacy, and security

> How Retina separates sign-in from tracked addresses and handles browser, cloud, provider, and AI data.

Retina uses public addresses and read-only data. Tracking a portfolio does not give Retina permission to move funds, approve tokens, place orders, or sign transactions.

## Sign-in identity

You can sign in with email, Google, X, an EVM wallet, or a Solana wallet.

Wallet sign-in uses an off-chain message that proves control of the address. The message cannot authorize a transaction or asset transfer.

Your sign-in identity remains separate from the addresses you track. You can add public addresses you do not control, including cold wallets and vault addresses.

## Browser and account copies

Retina keeps the active working copy in browser storage. A signed-in portfolio is also saved to the account so snapshots can sync and restore on another browser or device.

The browser copy supports fast local use. The account copy supports recovery, multi-device access, scheduled captures, and notifications.

## Cloud encryption

Saved portfolio objects are encrypted before they are written to private cloud object storage. Object names use opaque identifiers instead of wallet addresses.

This is server-side application encryption. It is not end-to-end encryption. Retina's Worker can decrypt the saved settings and portfolio data because automatic snapshots must run while your browser is closed.

## Data providers

Retina sends the public address and request details needed to retrieve balances, positions, prices, yields, rewards, risk data, and market information. Providers can see requests made to their services.

Retina uses a server proxy for providers that require protected credentials or server-side coordination. The portfolio is normalized into a combined view after those results return.

## Ask Retina

* Private mode calculates from the selected snapshot in your browser.
* Local AI runs the interpretation model on your device where supported.
* Cloud AI sends your question and a compact set of relevant facts to Gemini.

Choose the mode that matches the question and your privacy preference.

## Account deletion

Deleting your Retina account revokes access immediately and schedules deletion of saved account data. Data stored only in the current browser remains until you clear or replace it.
