Cookies & browser storage
What stays in your browser and how to manage it.
Updated November 7, 2026
Application storage
This application does not set its own cookies. It uses localStorage to remember theme, meter animation, speed test language, display units, server and mode preferences. Optional saved history contains up to ten completed test results. It excludes IP addresses and provider labels.
Managing saved results
Results history offers Clear history and CSV export. Turning off Remember results also removes saved measurements. Your browser’s site-data controls can erase preferences and history. Private browsing or blocked storage may prevent persistence. No account or cross-device synchronization is provided.
Hosting and external providers
The hosting layer may use its own authentication or security cookies, especially for an owner-private preview. Starting a Cloudflare measurement sends traffic to that service. The Inter typeface is served directly by this website. Read our privacy policy for provider processing.
Advertising
The Google AdSense script is integrated for site review and potential ad delivery. Google and its partners may use advertising cookies; see our privacy policy and Google Ads Settings. The local results preference is separate from advertising consent. Consent choices will be provided where required before serving ads that require consent. We do not use separate analytics scripts.
