# WhatsApp for lawyers: encrypted backups, transcripts and call recording

> For law firms whose clients write on WhatsApp: Kaption keeps a password-encrypted, searchable copy of client chats in a folder the firm controls, transcribes voice notes, records calls with consent and helps you follow up. Not legal advice.

A lost phone or a departing associate shouldn't take the client's record with it. A client chat lives on one phone, under one account, and WhatsApp's own backup only restores chats onto a phone. Kaption keeps a separate, password-encrypted copy in a folder the firm chooses, that you can open and search on any computer.

## Encrypted backups in a folder the firm controls

- One backup file of the WhatsApp chats in a folder you pick: inside the firm's Google Drive, OneDrive or iCloud Drive, or an external drive. Kaption does not sign in to those services, and its servers never receive the file.
- Every chat on the account: messages, contacts, groups, labels and voice-note transcripts.
- Messages deleted after they were backed up stay in the backup, marked "Deleted in WhatsApp".
- Paid plans add photos, videos, voice notes and documents, and update the backup every hour. Every plan can export a backup by hand.
- Locked with a password (10+ characters). Nobody, not even Kaption, can open it without the password, and it can't be recovered. Keep it in the firm's password manager.

## Find what a client said, months later

- The backup opens read-only, laid out like WhatsApp, and searches every chat and voice-note transcript at once.
- It opens on any computer with Kaption and the password, without the original phone.
- Connect Kaption to Claude or ChatGPT to search chats and transcripts while Kaption is open: https://kaptionai.com/mcp/

## Client voice notes, in writing

- Transcribe voice notes in WhatsApp Web (Chrome, Edge) and in the Kaption desktop app for Mac and Windows; automatic transcription; summaries of long voice notes and chats.
- On a Mac with macOS 26, the desktop app can transcribe on the computer; with cloud fallback off, the audio isn't sent to Kaption's servers.

## Record client calls, with consent

- The desktop app for Mac and Windows and the extension in Chrome and Edge record WhatsApp calls; each side is transcribed separately.
- Per number: Every call, Only when I press Record, or Off.
- Recording laws vary by country and state; many places require everyone on the call to agree. Neither WhatsApp nor Kaption tells the other person. The firm is responsible for informing clients and getting consent.

## Follow up on time

- Reminders ("Friday at 10am"), scheduled messages, and WhatsApp Business labels per client or matter (labels are kept in backups).

## Limits

Kaption is not legal advice. It makes no claim that a backup, export or recording is accepted as evidence or meets any professional, court or data-protection rule. Backups are view-only and don't restore chats into WhatsApp. Check your bar's and your local rules.
