# How Google sign-in stores your IOTA Watch device list

Without an account, this browser keeps 3 Miner IDs per project on Free. Google sign-in binds up to 3 devices per project on Free, or 100 per project on Pro to your account so you can open the same list elsewhere.

Google sign-in on IOTA Watch only binds a **list of public Miner IDs and labels**. It is not a wallet login and never asks for a password, private key, or seed phrase.

## Without signing in

- This browser can keep up to 3 devices per project on Free

- The list lives in local storage on this machine

- Another phone or computer will not see it unless you export and import a JSON backup

## After Google sign-in

- The same account can keep up to 3 devices per project on Free, or 100 per project on Pro

- Open [Account](https://iotahome.site/en/account) to see the name, email, and avatar Google provided

- Add, rename, and remove devices on the [dashboard](https://iotahome.site/en/app)

- Sign in on another device to see the same list

## What is stored

Public SS58 hotkeys, labels you typed, and when you added them. Telemetry is fetched from official public APIs. Details: [privacy notes](https://iotahome.site/en/privacy).

> Signing out does not delete the official training history. It only disconnects this browser from the bound list.
