By accessing or using 404Watcher ("the Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Service.
404Watcher provides automated monitoring of Meta (Facebook & Instagram) advertising links. The Service periodically scans your connected ad accounts to detect broken URLs (specifically 404 Not Found and 503 Service Unavailable errors).
The Service is offered in different tiers with specific quotas. You agree to operate within the limits of your selected tier:
* "Active Ad Account" refers to any account user explicitly selects for monitoring in the Dashboard.
Our order process is conducted by our online reseller Lemon Squeezy. Lemon Squeezy is the Merchant of Record for all our orders.
All sales are final and non-refundable.
Since 404Watcher provides a generic Free Tier allowing you to test the Service before purchasing, and because the Service grants immediate access to digital tools and data consuming server resources, we do not offer refunds.
By subscribing to a paid plan, you expressly agree that the supply of the Service begins immediately upon purchase, and you verify that you waive your right of withdrawal (including any 14-day cooling-off period under consumer protection laws). You may cancel your subscription at any time to stop future billing, but no partial refunds will be issued for the current period.
The Service is provided "as is" and "as available". We do not warrant that the Service will be uninterrupted or error-free. While we strive for high accuracy, we are not responsible for false positives or missed broken links due to external factors (e.g., website blocking, transient network issues).
To the maximum extent permitted by law, 404Watcher shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses.
Service Accuracy Disclaimer: 404Watcher is an automated assistance tool designed to identify broken links with high accuracy. Like antibacterial products that catch 99% of bacteria, our tool is designed to catch the vast majority of issues. However, due to the complex nature of the internet, false positives or false negatives may occur.
The Service is provided as a supplementary tool to aid your workflow, not as a guaranteed replacement for human oversight. You remain solely responsible for your advertising campaigns and any budget spent on broken links that the Service might technically miss.
