# Back up a note

> Keep your deposit note somewhere safe so the funds stay recoverable.

{% hint style="danger" %}
**Back up the note before you do anything else.** If you lose the note, MixFun cannot recover the funds. Non-custody is by design.
{% endhint %}

A note is the only thing that can withdraw a deposit from MixFun. Losing the note means the funds cannot be recovered. This guide lists the practical options for keeping a note safe.

### Right after depositing

1. **Read the note on screen.** MixFun shows the note once after a deposit confirms.
2. **Copy the note.** Use the copy-to-clipboard button or select and copy the text.
3. **Save the note in two places.** Pick two of: a password manager, a note-taking app you control, an encrypted file on your device, a paper backup, or a screenshot kept offline.
4. **Verify your copy.** Open at least one of the saved copies and compare it to the original on screen. Mistyped or truncated notes are the most common reason recovery fails.

### For signed-in accounts

If you were signed in at deposit time, MixFun stored an encrypted copy of the note for you. You can browse these copies under your account. Encryption happens on your device before upload, so MixFun only stores ciphertext.

These stored copies are a convenience, not a replacement for your own backup. If you lose access to the wallet that holds the decryption key, the stored copy is also unrecoverable.

### Share link as a temporary backup

If you plan to share the note with a recipient, a MixFun share link can double as a short-lived backup. Share links have a configurable max-claims count (default 1) and an expiry. Do not rely on a share link as long-term storage: once consumed or expired, the note stored there is gone.

### What not to do

* **Do not store the note in a cloud service you cannot encrypt yourself.** A plaintext note in Dropbox, iCloud, or Google Drive is retrievable by anyone who compromises that account.
* **Do not share the note in a group chat or public channel.** Anyone with the note can withdraw.
* **Do not leave the note in a draft email or unsaved screenshot cache.** These are common places notes disappear.

See [Notes and custody](/mixfun/concepts/notes-and-custody.md) for the concept behind the note.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mixfun.gitbook.io/mixfun/guides/back-up-a-note.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
