# FAQ

> Quick answers.

## The basics

> [accordion] Is it free?
>
> Yes. It is open source under Apache 2.0.

> [accordion] Can it spend my Bitcoin?
>
> No. It is watch-only. It never has your private keys or seed phrase. It refuses any wallet import that includes a private key.

> [accordion] Do I need a Hoseki account?
>
> No.

> [accordion] Can Hoseki see my data?
>
> No. Your data stays on your device. See [Privacy and security](https://help.hoseki.app/bitcoin-control-center/privacy-security.md).

> [accordion] Do I need my own node?
>
> No. You need an Electrum server. On desktop, the introduction lets you keep Blockstream's public server or connect your own. Your own is best for privacy.

> [accordion] Does it work on Intel Macs or Linux desktops?
>
> Not yet. Use an Apple Silicon Mac, Windows x64, or StartOS. Umbrel is coming soon.

> [accordion] Where do I install it on StartOS?
>
> From the **Start9 Community Registry** in the StartOS **Marketplace**. See [Install on StartOS](https://help.hoseki.app/bitcoin-control-center/getting-started/install-startos.md).

> [accordion] Can I track a wallet without verifying it?
>
> Yes. Select **Add Account** → **Track Balance, ETF, or xpub** → **xpub or Descriptor**. The wallet shows as **Unverified**. It counts in your totals but not on statements. See [Track a wallet](https://help.hoseki.app/bitcoin-control-center/accounts/xpub-and-descriptors.md#track-a-wallet).

> [accordion] Does it work with Bitkey?
>
> Yes, as an **Unverified** account. Bitkey can't sign a message to prove ownership, so it stays off statements. See [Bitkey](https://help.hoseki.app/bitcoin-control-center/accounts/bitkey.md).

> [accordion] Can I use it on my phone?
>
> There is no mobile app. On StartOS, you can open the web interface in a phone browser. Hardware wallets need a computer.

> [accordion] How do I get help?
>
> Select the question-mark **Help** icon at the top of any page. It sits next to **Lock** and **Settings**, and opens this Help Center.

## Accounts

> [accordion] Which wallets and exchanges work?
>
> Ledger, Trezor, COLDCARD, Keystone, multisig, and any wallet by xpub or descriptor. Coinbase, Kraken, Robinhood, and Strike. Plus manual Bitcoin and ETFs. See [How accounts work](https://help.hoseki.app/bitcoin-control-center/accounts/how-accounts-work.md).

> [accordion] What's the difference between pending and verified?
>
> Both are tracked. Verified wallets have proven control by signing a message, so they can go on statements. See [Verify ownership](https://help.hoseki.app/bitcoin-control-center/accounts/verify-ownership.md).

> [accordion] Does signing a message cost anything or move funds?
>
> No. It's not a transaction. Nothing is broadcast.

> [accordion] Can I track testnet?
>
> Not in the packaged apps. They are mainnet only.

> [accordion] Can I track other coins?
>
> No. Control Center is Bitcoin only.

## Numbers and statements

> [accordion] Does it track cost basis or gains?
>
> No. It tracks how much Bitcoin you hold over time. USD figures use today's price. See [Home and Portfolio](https://help.hoseki.app/bitcoin-control-center/portfolio/home-and-portfolio.md).

> [accordion] Can I see balances in another currency?
>
> Home and Portfolio show USD. Statements can use USD, CAD, GBP, or EUR.

> [accordion] Can I use a statement for taxes?
>
> A statement shows your Bitcoin balances and transactions for a period. It is not tax advice or a tax form. Ask your tax professional what they need.

> [accordion] Why aren't my exchanges on my statement?
>
> Statements cover self-custody wallets you've verified. Your exchange can provide its own statement.

## Data

> [accordion] What if I lose my computer?
>
> Your coins are safe. Restore from a [backup](https://help.hoseki.app/bitcoin-control-center/maintenance/backup-restore.md), or re-add your accounts.

> [accordion] Does it record history when it's closed?
>
> No. It records balances about every 15 minutes while running. Wallet history is rebuilt from the blockchain when needed.

> [accordion] Is there dark mode?
>
> Not yet.
