Where BuzzRelay stores your data

Short answer

Everything lives in %APPDATA%\BuzzRelay\ on your own computer: a SQLite database with contacts, templates and campaign history, a browser profile per connected device, uploaded media, exported logs and the application log. None of it is sent to us. That means there is no cloud backup — if the machine fails and you have no copy of that folder, the data is gone.

The folder

All BuzzRelay data lives under %APPDATA%\BuzzRelay\. Paste that into the Windows Explorer address bar to open it.

%APPDATA%\BuzzRelay\
├── database.db              contacts, groups, templates, campaigns, settings
├── device_profiles\<id>\    WhatsApp Web session per device
├── live_chat_profiles\<id>\  Live Chat session per device
├── media\                    uploaded template attachments
├── exports\                  campaign CSVs and logs you export
└── logs\app.log              application log

Item	Contains	Losing it means
`database.db`	Contacts, custom fields, groups, templates, campaigns and their results, settings	Everything is gone — this is the important file
`device_profiles\`	The logged-in WhatsApp Web session per device	Re-scan the QR codes
`live_chat_profiles\`	Separate session used by Live Chat	Live Chat asks you to log in again
`media\`	Images, video, audio and documents used in templates	Templates lose their attachments
`exports\`	Files you exported yourself	Nothing — you can export again
`logs\app.log`	Diagnostic log, rotating, capped at a few megabytes	Nothing, unless you are diagnosing a problem

The database is SQLite

database.db is a single SQLite file holding everything. That has practical consequences:

Backing up is copying one file.
Close BuzzRelay before copying it. Copying while the app is running can capture a half-written state.
It grows slowly. Tens of thousands of contacts and a long campaign history still amount to a small file.
It is not encrypted. Anyone with access to the machine and its user profile can read it.

Your contact data is personal data. Under GDPR, the DPDP Act and similar regimes you are responsible for protecting it. Use a password-protected Windows account, encrypt the drive if the machine is portable, and think carefully before putting BuzzRelay on a shared or public computer. See Is bulk WhatsApp messaging legal?

Backing up

Close BuzzRelay completely.
Open %APPDATA%\ in Explorer.
Copy the whole BuzzRelay folder somewhere safe.

To back up only what cannot be recreated, copy database.db and the media folder. Device profiles are not worth backing up — re-scanning a QR code is quicker than restoring them, and a stale session may not resume anyway.

Do it before every update, and on a schedule if your list matters. There is no server-side copy. If the disk fails, whatever you have locally is all there is.

Moving to another computer

Back up the folder on the old machine as above.
Install BuzzRelay on the new machine and let the first-launch browser download finish.
Close it.
Copy database.db and media\ into %APPDATA%\BuzzRelay\ on the new machine, replacing what is there.
Start BuzzRelay and re-connect your devices by scanning QR codes again.

The licence is bound to hardware, so a new machine needs a licence reset — email support before you plan the move. See Activate your license.

What leaves your computer

Goes out	Where to
Your messages	WhatsApp, through your own account
Licence checks	Our licence server
Update checks	Our update server
AI generation prompts	Only the AI provider you configured, and only when you use that feature
Your contact list	Nowhere
Your campaign content	Nowhere but WhatsApp

If you use AI drafting, the prompt goes to whichever provider you configured with your own API key — that is a direct relationship between you and them, subject to their terms.

Frequently asked questions

Where does BuzzRelay store contacts and campaigns?

In a SQLite database at %APPDATA%\BuzzRelay\database.db on your own computer, alongside browser profiles for each device, uploaded media, exports and the application log. Nothing is stored on our servers.

How do I back up my BuzzRelay data?

Close BuzzRelay, then copy the whole %APPDATA%\BuzzRelay\ folder somewhere safe. At minimum copy database.db and the media folder — those are the parts that cannot be recreated. There is no cloud backup.

How do I move BuzzRelay to a new computer?

Back up the folder, install BuzzRelay on the new machine and let the first-launch browser download finish, close it, copy database.db and media\ into %APPDATA%\BuzzRelay\, then reconnect your devices by scanning QR codes. The licence is hardware-bound, so contact support for a reset first.

Is my contact database encrypted?

No. It is a standard SQLite file readable by anyone with access to that Windows user profile. Since it holds personal data, protect the machine with a password and consider full-disk encryption on portable computers.
