What our analysis found
History Trends Unlimited, used by 60,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in May 2026.
Analyst notes
Extension operates entirely locally: it stores browsing history in a local SQLite database via WebAssembly, provides search and trends, and exports data as local files. The strict Content Security Policy (connect‑src 'none') prevents any network connections. The ‘history’, ‘offscreen’, and ‘unlimitedStorage’ permissions are essential for the core functionality and are not abused. Publisher is trusted (Google trusted badge, featured listing, long‑standing extension with 60k users and 4.0 rating). All code reviewed matches the stated purpose; no hidden network calls, tracking, or privilege escalation found. The ML‑model high‑risk score is a false positive driven by broad permissions and use of WASM, both necessary for local history storage.

Read the publisher’s full description
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. Features: * 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. NOTES: * 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.
