Where Does the Perplexity Desktop App Store Local Data?
Perplexity desktop app local data on Windows and macOS, and which folders hold cache versus account state.
Last updated
The Perplexity desktop apps for Windows and Mac wrap the web experience with extra powers like local file access. Threads and projects sync to your account, so the local footprint is cache, logs and login state.
Exact folder names follow the usual Electron conventions and can shift between releases. Confirm the Perplexity entry exists before scripting anything against it.
Where Perplexity stores this, by platform
%APPDATA%\Perplexity
Reported Electron user-data location for settings, cache and session state. Folder naming may vary by release, so verify on your install. Threads themselves sync from your account, so clearing this only signs you out.
~/Library/Application Support/Perplexity
Same role as the Windows folder: cache and local state, with threads syncing from the cloud. Use Finder Go > Go to Folder to reach it.
Frequently asked questions
Will reinstalling the Perplexity app delete my threads?
No. Threads, projects and history live on your Perplexity account and return on sign-in. Local folders hold only cache and state.
The Perplexity app shows a blank window. What do I clear?
Quit the app, remove its Application Support or AppData folder, and relaunch. Perplexity support also recommends confirming you run the current version before deeper troubleshooting.
