MsgSaver privacy policy
MsgSaver is a Windows app that keeps a copy of messages that are deleted or unsent in the user's own WhatsApp and Instagram chats.
What MsgSaver stores
When a message in one of your chats is deleted, unsent or edited, MsgSaver saves that message on your PC: the text, any photo, video or voice note it had, the chat name, the sender name and the time. In WhatsApp groups it also saves the last 4 digits of the sender's phone number (as shown in the group's member list) and, when the sender has a visible profile photo, that photo, so you can tell members with the same name apart.
To be able to do this, MsgSaver has to know what a message said before it is deleted. So it keeps, encrypted on your PC: the text and type of the messages you receive (WhatsApp: 7 days; Instagram: the most recent 15,000 messages), the information needed to download WhatsApp media again, and recently received media files (7 days for WhatsApp, 30 days for Instagram). After that they are deleted automatically. Nothing from this copy is shown or kept longer unless the message is deleted or edited.
Where it is stored
Only on your PC, encrypted with AES-256 using a key protected by your Windows account. The developer never receives any of it.
What is sent over the internet
MsgSaver connects to WhatsApp (web.whatsapp.com) and Instagram (instagram.com), the same way a web browser does when you use them. Your sign-in for those services is handled by WhatsApp and Instagram; MsgSaver does not see or store your passwords. MsgSaver has no ads and no tracking.
Diagnostics and error reports
MsgSaver sends reports so the developer can see how many people use it and where, and fix problems. The website version always sends a small check-in when it starts and every few hours: a random install ID created on your PC (not linked to any account, name or phone number), the app version, that it is the website version, the Windows version, the app language and how long the app has been running. The server records the country, region and city your connection comes from; your IP address is not stored. "Send diagnostics" is on by default in the website version and adds: for WhatsApp and Instagram, whether it is turned on and connected, whether it restarted and how many messages were saved (only the numbers); which settings you use and how often you open the window or press Connect (only on or off and numbers, never which chats); and error reports, with file paths, web addresses, quoted text, email addresses and long numbers removed. In the website version, error reports also go to Sentry (sentry.io, servers in the European Union), the service the developer uses to track errors, which also records the approximate location of your connection and keeps error reports for up to 90 days. Turn "Send diagnostics" off in Settings > General and only the check-in is sent; unsent error reports are deleted. The Microsoft Store version sends nothing at all until you turn on "Send diagnostics" on the welcome screen or in Settings, and never uses Sentry. Reports never contain message text, chat, contact or group names, phone numbers, photos, voice notes or account names. Error reports are kept for 90 days, and an install that stops reporting is deleted after a year.
Other people's messages
Saved messages include messages other people sent to you. You are responsible for using MsgSaver lawfully and only on your own accounts and your own PC.
Your control
You can delete any saved message, delete everything (this also deletes the encrypted copy of received messages described above), choose which chats are saved, set how long messages are kept, and sign out of each service from the app. Uninstalling the Microsoft Store version removes all of its data. The version installed from the website keeps its data folder after uninstalling, so that a reinstall keeps your messages; to remove it, use "Delete all" before uninstalling, or delete the folder %APPDATA%\MsgSaver.
