Optional performance reporting

Reporting is off unless you enable it. If enabled, PepTables collects page-speed measurements grouped by broad page category, mobile/desktop size, day and quality band. The stored reports contain no account IDs, full URLs, search queries or visitor IDs. Choosing either option leaves the directory and your account features available.

Optional reporting is off by default. Enable JavaScript to check or change this browser’s saved preference.

You can change your mind here at any time. A choice expires after 180 days in this browser. Global Privacy Control or Do Not Track overrides an allow choice. Clearing browser storage resets reporting to off. Until you choose to allow it, reporting stays off.

Storage used for requested features

• __Host-peptables_challenge: a necessary, secure, HttpOnly cookie binding a sign-in code to the browser that requested it. It lasts up to 10 minutes and is cleared on successful verification.
• __Host-peptables_session: a necessary, secure, HttpOnly cookie that keeps you signed in for up to seven days. Signing out clears it and revokes the session.
• peptables:comparison:v1: session storage containing up to three vendor IDs you select for comparison. It lasts for the tab’s browser session, including any session restoration your browser performs. “Clear” in the comparison tray removes the selection.
• peptables:privacy:v1: local storage remembering the reporting choice you make here and its 180-day expiry. An expired entry can remain until you clear site storage or make a new choice, but it no longer permits reporting. It is not a visitor identifier and is not sent to our server.

Blocking necessary cookies prevents sign-in from working. Blocking browser storage can prevent preferences and comparisons from persisting; optional reporting stays off when permission cannot be read. Your browser may cache public pages, fonts and images to load the directory faster. This cache is not used to track you.

Security services and external websites

Cloudflare Turnstile runs on sign-in to prevent automated abuse and processes technical browser and network signals. Cloudflare may use security storage or cookies according to the challenge configuration. See its Turnstile Privacy Addendum for details. Security checks are separate from optional performance reporting.

We do not use advertising or cross-site tracking cookies. Linked vendor and laboratory websites may use their own cookies after you visit them. Their policies and controls apply there.
