Battle.net
Battle.net stores Chromium-based launcher web cache data under its local Cache folder so the app can quickly render the shop, news, login, and game library views without downloading every asset again. That cache typically includes HTTP disk cache entries, cookies and session-related web data, image assets, JavaScript bundles, and compiled browser-side code, while its Logs folders accumulate launcher diagnostic logs and update traces over time. Kudu removes the Battle.net web cache and log files when they become stale or oversized, without touching installed games, account data, saved passwords managed elsewhere, or game settings.
Why clean Battle.net?
- Stale Chromium web cache after a launcher update can leave the Battle.net home page blank or partially rendered until the old HTML, scripts, and assets are removed
- Corrupted cached JavaScript bundles or image assets can make the Friends, Store, or Games tabs load endlessly, show missing artwork, or fail to respond to clicks
- Expired or inconsistent cached session data can trigger repeated sign-in prompts, spinning authentication screens, or a launcher window that never finishes connecting
- Oversized HTTP disk cache can waste several hundred megabytes and slow launcher startup while Battle.net revalidates old web assets you no longer need
- Accumulated Battle.net logs and update traces grow quietly in the background and are only useful for troubleshooting, but users notice reduced free space and harder-to-find current log entries
- Old cached storefront and content-delivery responses can cause outdated promotions, patch notes, or game metadata to appear until the launcher fetches a clean copy
