Where are WhatsApp messages stored?
Processed locally on your iPhone.
Chat Archive opens the WhatsApp export ZIP you choose and processes imported chat content on your iPhone. Your imported messages, media, voice messages, and chat history are not uploaded to Chat Archive servers.
Processed on your iPhone
Chat Archive does not upload imported chat content to Chat Archive servers to open, search, review, or preview the archive.
You choose the ZIP
Select the file exported from WhatsApp.
Chat Archive opens it
The app reads the export, rebuilds the chat, indexes it for search, and previews PDFs on your iPhone.
You control the files you create
ZIP files, PDFs, screenshots, cloud files, and shared attachments should be handled like copies of the original chat.
What happens during import
The app reads the WhatsApp export ZIP, turns the text file and included attachments into a readable chat, and builds local indexes so you can search the archive.
Messages
Message text, dates, participants, and chat order come from the export file.
Media and files
Photos, videos, documents, audio, and other attachments are shown when WhatsApp included them in the ZIP.
Voice messages
Voice-message transcription runs on your iPhone when the audio and device support it.
PDF preview
The PDF is generated from the imported archive on your iPhone before you decide whether to save, share, or print.
Ready to review an export on your iPhone?
Open the ZIP in Chat Archive, review it on iPhone, and choose what to save or share.
Imported chat content is handled on your device.
What about saving in iCloud?
Chat Archive itself does not upload your imported chats to iCloud. Apple backup and transfer features may still preserve Chat Archive app data when your device is configured to include it.
iCloud Backup
If you use iCloud Backup and Chat Archive app data is included in the backup, imported archives can be backed up with the rest of your iPhone data.
Moving to a new iPhone
When you restore from an iCloud backup or transfer data from an old iPhone to a new one, Chat Archive data may be preserved with your other app data.
iCloud Drive is separate
If you save the original ZIP or an exported PDF to iCloud Drive, that saved file is handled by iCloud Drive, not by Chat Archive cloud sync.
Manage it in Settings
Use iPhone backup and iCloud settings to decide what app data and files are included in your Apple backups.
No live WhatsApp access
Chat Archive does not connect to your WhatsApp account or sync live messages. It only opens WhatsApp export ZIP files you manually import.
Good practice
Keep the source ZIP somewhere you trust. Review the archive before saving or sharing a PDF. Delete temporary transfer copies you no longer need.
Independent app note
Chat Archive is independent and is not affiliated with WhatsApp, Meta, or their products.
Private handling starts with the export
