HtmlRunner grants you a personal, non-exclusive, non-transferable license to use Multisession for lawful multi-account management, QA testing, and privacy sandboxing.
Strict anti-detect spoofs User-Agent, Client Hints, and JS fingerprint APIs. Captchas including Turnstile may fail while strict is on. Turn it off for captcha-friendly logins — this is expected behavior, not a defect.
Switching wipes live browser state before restoring the target vault. If the browser crashes mid-switch the engine backs up first and keeps a pending-restore map, but HtmlRunner is not liable for lost logins, cookies, or storage. Export critical work separately.
Provided "as is" without warranties of any kind. To the maximum extent permitted by law, HtmlRunner's liability is limited to the amount you paid for the extension (zero for the free version).
We may update these terms with versioned releases. Continued use after an update constitutes acceptance. Contact: contact@htmlrunner.com · htmlrunner.com.
