Privacy policy

Who runs this site

Bufferbloat.org is an independent public-interest internet utility. For privacy questions, deletion requests, or other requests about your data, use the contact form.

What the test collects

When you run the test, the browser measures latency / ping samples, download throughput, upload throughput, timing information, scorecard values, and application-performance ratings. The site may also record technical context such as browser user agent, device class, viewport bucket, referrer host, country/region/city from infrastructure headers, and a per-tab session/run identifier.

This data is used to produce your result, diagnose measurement reliability, improve the test, understand aggregate usage, and protect the service from misleading or broken runs.

Shared results

If a result is shared or stored, the saved record can include the scorecard, measurement values, raw scored latency samples, technical export fields, generated share ID, and creation time. Shared result links are intended to be accessible to anyone who has the link.

Email signups and contact messages

If you sign up for updates, the site stores your email address with rough location, browser user agent, and completed-test count. If you submit the contact form, the site stores and forwards your message, optional email address, category, page path, browser user agent, rough location, and optional screenshot metadata. Screenshots are forwarded by email when forwarding is configured.

Cookies, local storage, and analytics

The site uses local storage to remember a small completed-test count in your browser. The signup form sets a first-party cookie named bufferbloat_signup so it does not keep asking after a successful signup. These are not used for advertising.

Bufferbloat.org does not use ad tracking or sell personal data. Server infrastructure may process normal request data such as IP address, timestamps, user agent, and security logs.

Service providers

The site uses infrastructure and services including Cloudflare, Vercel, GitHub, and an email forwarding provider when contact email forwarding is configured. These providers may process data needed to host, protect, deploy, observe, store, or forward the site and its messages.

Retention

Test analytics and shared result records are kept for product improvement, debugging, abuse prevention, and public-result access. Signup emails are kept until you ask to be removed. Contact messages are kept long enough to respond and maintain a record of requests. Infrastructure logs follow the retention settings of the relevant providers.

Your choices and rights

You can avoid sharing a result by not using the share link. You can avoid signup collection by not entering an email address. You can ask for access, correction, deletion, or restriction of personal data by using the contact form.

Changes

This policy may change as the site evolves. The current version is published on this page.
