Privacy Policy
Last updated: October 2026
Baezu Systems ("we", "us", "our") operates the Baezu Systems platform and API services. This policy explains what information we collect when you use our services, how we use it, and your choices.
Information We Collect
API Usage Data
When you use our API services (directly or through integrated websites like CheckIfSiteUp), we process the URLs you submit to perform the requested checks. We do not associate these URLs with your identity.
Technical Logs
We temporarily log requests for rate-limiting, abuse prevention, and service reliability. These logs include IP addresses, request timestamps, and response codes. They are short-lived and not used to build profiles of individuals.
Analytics
We may use privacy-focused analytics to understand overall traffic patterns (which endpoints are popular, error rates, latency). This analytics avoids collecting personal information.
How We Use Information
- To perform the website checks you request (health, DNS, SSL, HTTP)
- To protect the service from abuse and excessive use (rate limiting)
- To understand aggregate usage and improve the services
- To ensure service reliability and debug issues
What We Don't Do
- We don't sell your personal information
- We don't store the URLs you check for marketing purposes
- We don't track you across other websites
- We don't require accounts for API access
Data Retention
Technical logs are retained only as long as necessary for rate limiting and security (typically 24-72 hours). Aggregate analytics may be retained longer in a form that does not identify individuals.
Third-Party Services
Our API may be integrated into third-party websites (e.g., CheckIfSiteUp). Those websites have their own privacy policies. We do not control their data practices.
Your Rights
Depending on your location, you may have rights to access, correct, or delete personal information, or to object to certain processing. Because we collect very little personal information, in many cases there is nothing to retrieve. To make a request, contact us at baezu.com/contact.
Changes
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
