# WhatsApp backup for lawyers: an encrypted, searchable copy of client chats

> Keep a password-encrypted, searchable copy of client WhatsApp conversations in a folder your firm controls, so a lost phone doesn't take the record with it.

Clients write to lawyers on WhatsApp whether the firm planned for it or not. Instructions, dates, photos of documents, a voice note sent at 11 p.m. explaining what really happened. Over a long matter, that chat becomes part of how you know the case.

The trouble is that it lives on one phone, under one account. If the phone is lost, the account is banned or a colleague leaves with the number, the history can go with them. This article explains how to keep your own password-encrypted, searchable copy of those conversations in a folder the firm controls.

*Updated October 2026*

## Why WhatsApp's own backup is not enough for a case file

WhatsApp backs up a phone to iCloud or Google Drive so the chats can be restored onto a new phone. That is useful, but it is not a record you can work with:

- You cannot open it on a computer and read it.
- You cannot search it outside WhatsApp.
- It depends on the phone, the number and the account still being available.

"Export chat" sends a single conversation as a text file, one chat at a time, by hand. Across dozens of clients it rarely happens consistently.

## What Kaption Backups keeps

[Kaption Backups](/backups/) keeps one encrypted backup file of your WhatsApp chats in a folder you choose. It works in WhatsApp Web with the Kaption extension for Chrome and Edge, and in the [Kaption desktop app for Mac and Windows](/desktop/). On paid plans it updates every hour with only what changed.

For a law practice, the useful parts are:

- **Every chat on the account:** messages, contacts, groups and labels. If you use labels per client or per matter, they come along.
- **Voice-note transcripts.** A client's long voice note becomes text you can search and quote in your notes.
- **Deleted messages.** Messages a client deletes after they were backed up stay in the backup, marked "Deleted in WhatsApp".
- **Documents and media on paid plans.** PDFs, photos of contracts, scans and voice notes the client sent.

Notes, reminders and AI summaries are not included in backups.

## A folder the firm controls

The backup is a file in a folder you pick, not an account on someone else's service. Choose a folder inside the firm's Google Drive, OneDrive or iCloud Drive, or on an external drive, and that service syncs the encrypted file like any other document.

Kaption does not connect to, sign in to or upload to those services, and Kaption's servers never receive the file. Who can reach the folder is decided by the firm's own sharing settings.

## Encrypted with a password only you hold

Each backup is locked with a password you set, at least 10 characters. Nobody, not even Kaption, can open the file without it. That also means there is no recovery: if the password is forgotten, the backup cannot be opened. Keep it in the firm's password manager, not on a sticky note.

## Finding what a client said, months later

Open the backup and it appears read-only in a new tab, laid out like WhatsApp. From there you can:

- Search every chat and every voice-note transcript at once, for a name, an amount or a date
- Filter to groups, chats with media or chats with transcripts
- Preview documents, photos and voice notes (on paid plans, when media is included)

The file is decrypted in memory on your computer and nothing is uploaded. You can open the same backup in Kaption on another computer with the password, so a partner can review a client's history without the original phone.

## WhatsApp's backup vs your own copy

<table>
  <thead>
    <tr><th></th><th>WhatsApp's own backup</th><th>Kaption Backups</th></tr>
  </thead>
  <tbody>
    <tr><td>Purpose</td><td>Restore chats onto a phone</td><td>Keep a readable, searchable copy</td></tr>
    <tr><td>Where it lives</td><td>The phone owner's iCloud or Google Drive</td><td>A folder you choose</td></tr>
    <tr><td>Read on a computer</td><td>No</td><td>Yes, view-only</td></tr>
    <tr><td>Search voice notes</td><td>No</td><td>Yes, through transcripts</td></tr>
    <tr><td>Documents and media</td><td>Yes</td><td>Paid plans</td></tr>
  </tbody>
</table>

Keep both. WhatsApp's backup gets the chats onto a new phone; Kaption's keeps them readable when there is no phone at all.

## Setting it up for a practice

1. Install the Kaption extension in Chrome or Edge, or the Kaption desktop app, on the computer where the firm's WhatsApp number runs.
2. In Backups, pick a folder inside the firm's cloud drive.
3. Set a strong password and store it where the firm keeps its credentials.
4. Use **Export now** for a one-off copy (available on every plan, including Free), or turn on continuous hourly backups on a paid plan.
5. After a browser restart, accept the prompt to allow folder access again if it appears, so backups keep running.

## What it does not do

Be clear with yourself and your team about the limits:

- **View-only.** It cannot restore chats into WhatsApp or move them to another phone.
- **Not a compliance tool.** Kaption makes no claim that a backup meets any professional, evidentiary or data-protection rule. Whether and how you keep client messages is your decision.
- **Recording calls too?** Kaption can also record WhatsApp calls with clients, with the other person's consent. See [call recording](/call-recording/).

## FAQ

### Can I keep a copy of client WhatsApp chats if I lose my phone?

Yes, if the backup was made before. Kaption keeps an encrypted backup file in a folder you choose, and you can open and search it on a computer without the phone.

### Does the backup include documents clients send?

On paid plans, yes: documents, photos, videos and voice notes. On Free, you can export a backup with messages and voice-note transcripts.

### Can Kaption read our clients' messages?

No. The backup is encrypted with your password and Kaption's servers never receive the file or the password.

### Can I restore the backup into WhatsApp?

No. Kaption backups are view-only. They are meant for reading and searching, not for moving chats to a phone.

### Can colleagues open the backup?

Anyone with access to the folder and the password can open it in Kaption on their computer. Share the password only with the people who should see the chats.
