RedFlag is an accessibility auditing service consisting of a Chrome browser extension and a web dashboard. It lets you scan web pages for WCAG 2.1 and 2.2 AA violations, track issues over time, and share reports with clients.
By creating an account or using the extension, you agree to these terms. If you do not agree, do not use RedFlag.
You must provide a valid email address to create an account. You are responsible for keeping your login credentials secure. You may not share your account with others or use RedFlag on behalf of someone else without their knowledge.
We reserve the right to suspend or terminate accounts that violate these terms.
Free plan. No payment required. Scanning is limited to a reduced view of violations per page. Saved dashboard data and full violation details require a Pro account.
Pro plan. $15 USD per month (or the price shown at checkout), billed monthly in advance via Stripe. All prices are in US dollars. Pro gives you full violation details, unlimited domains, full-site scanning (up to 25 pages per crawl), CSV export, and client portals.
Cancellation. You may cancel your Pro subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period. We do not provide pro-rata refunds for partial months.
Price changes. We will give you at least 30 days' notice before changing the Pro plan price. If you do not cancel before the change takes effect, you accept the new price.
You may use RedFlag only on websites you own or have explicit permission to scan. You may not:
You agree to indemnify and hold Qern Pty Ltd harmless from any claim, damage, or expense arising from your use of RedFlag in violation of these terms, including scanning websites without authorisation.
RedFlag uses axe-core to detect accessibility violations automatically. Automated tools cannot detect all accessibility issues — some WCAG criteria require manual testing (for example, checking that alternative text is meaningful, or that a form can be completed using only a keyboard). RedFlag results should be treated as a starting point, not a complete audit.
We make no warranty that RedFlag will detect every accessibility violation on a scanned page, or that a page with zero RedFlag violations is fully WCAG compliant.
RedFlag and its software are owned by Qern Pty Ltd. You retain ownership of the websites you scan and the data you store in your account. You grant us a limited licence to store and display that data in order to provide the service.
To the maximum extent permitted by law, RedFlag is provided "as is" without warranty of any kind. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including reliance on scan results in accessibility audits or legal proceedings.
Our total liability to you in any 12-month period is capped at the amount you paid us in that period.
Your use of RedFlag is also governed by our Privacy Policy, which is incorporated into these terms by reference. By using RedFlag, you agree to the collection and use of your information as described in the Privacy Policy.
We may modify or discontinue features at any time. For material changes that affect paid customers, we will give at least 30 days' notice where reasonably practicable.
These terms are governed by the laws of the Australian Capital Territory, Australia. Any disputes will be subject to the non-exclusive jurisdiction of the courts of the ACT.
