Where Does Postman Store Collections and Data?
Postman local app data on Windows, macOS and Linux, and what syncs to your account instead.
Last updated
Postman syncs collections, environments and history to your account, so the cloud is the real store for signed-in work. The local folder holds cache, logs, backups and the offline Scratch Pad data.
That local copy matters most for unsigned work and crash recovery. Session backups inside it have rescued collections after failed updates.
Where Postman stores this, by platform
%APPDATA%\Postman
Holds session backups, IndexedDB data, logs and the partition storage. Signed-in collections re-download from your account, so this folder is a fallback rather than the primary store.
~/Library/Application Support/Postman
Same backups and local storage role. Reach it through Finder Go > Go to Folder.
~/.config/Postman
Same layout as the other builds. Check the Session and backup subfolders first when recovering after a crash.
Frequently asked questions
Will reinstalling Postman delete my collections?
Not if you signed in: collections sync back from your account. Scratch Pad data lives only locally, so export it first.
Postman lost data after an update. Where do I look?
Check the backup and session folders inside the local data directory above before signing out or clearing anything. Copy the folder aside immediately to freeze recovery options.
