# Save your note securely

After making a deposit, you will receive a **unique note** — this is the only proof that you are the owner of the deposited funds. You’ll need this note later to **withdraw anonymously**.

The note looks like this:

```
bindowscash-bnb-0.1-0x<nullifier>-0x<contract>
```

This note contains two essential secrets:

* The **nullifier**, which prevents double spending and contains the encrypted secret
* The **contract**, which is routing your note to the correct pool

#### 🛑 If you lose this note, you lose access to your funds. There is no way to recover it.

***

#### ✅ Tips for storing your note safely:

* **Store it in a secure password manager** (e.g. 1Password, Bitwarden, KeePass)
* **Back it up offline**: write it down on paper and store it in a safe location
* **Do not take a screenshot or store it in plain text** on your computer or phone
* **Avoid cloud storage** unless encrypted (e.g. use a GPG-encrypted file or vault)
* **Do not share the note with anyone** — anyone who holds it can withdraw your funds
* **Never paste it into a public chat or online form**, even for support or administrators

***

#### Optional: Encrypt your note

For added protection, you can encrypt your note with a passphrase using tools like:

* [GPG (GNU Privacy Guard)](https://gnupg.org/)
* [AES encryption](https://asecuritysite.com/encryption/aes)

***

Treat your note like a **private key**. It’s your anonymous ticket to reclaim your funds — If lost, the funds are locked forever.
