Search and analyze your unlimited history.

What is History Trends Unlimited?
'History Trends Unlimited' is a Chrome extension designed to save your browsing history beyond Chrome's typical 3-month limit by syncing it to a local database. The extension provides tools to interactively analyze this history, including pie charts, bar graphs, and keyword search options. It also offers an export function for data analysis beyond the extension. Importantly, the extension saves history separately from Chrome's history, so local clearing will not affect the data stored by this extension.

History Trends Unlimited regularly syncs your history to a local database to work around the (approximate) 3-month time limit imposed by Chrome. Your history is saved locally; it's never shared or sent over the network.


  • Interactive charts and stats. Click any of the bar/line/pie charts to filter by a value.
  • Search your history by keyword. Or browse it chronologically.
  • Access the raw data to perform your own analysis. Click the "Export These Results" link on the Trends or Search page.
  • Transfer your history to a new computer. See instructions on the Options page.


  • This extension now requires a minimum of Chrome v109.
  • Uninstalling this extension will delete all of the history it has saved. To create a backup of your history, use the "Export History" button on the Options page.
  • This extension stores your history separate from Chrome's history, which means 1) clearing Chrome's history will not delete your history in this extension, and 2) this extension will not preserve the color of links you have already visited.

Very useful add-on which would be 5-star worthy with ease as Google itself has opted to not provide browsing history locally for longer than ~90 days, but as of late (September 2023 -> onwards) it has become unreliable at keeping the history accessible due to recent changes on Chrome which causes losing all history due to database corruption(s). Here's hoping that the issue can be fixed, as the extension has been very reliable and powerful tool during my 4 years of use before these recent issues.

History Trends Unlimited uses a storage system (Web SQL) that will soon be removed by Chrome (details can be found here). Your data must be migrated to a new storage system (SQLite WASM). The migration is simple: just follow the steps below. You must migrate to continue using this extension. If you don't migrate, your data will eventually be deleted by Chrome! please fix it,it's very useful extension.
