This Privacy Policy explains how Vantum Works LLC ("Vantum Works", "we", "us", or "our"), the company that owns and operates the Link Shrink service, collects, uses, and protects personal information when you use our services.
1. Information We Collect
1.1 Account Information
- Email address
- Account credentials
- Workspace and subscription details
1.2 Link and Analytics Data
When a shortened link is accessed, we may collect:
- Timestamp
- Referrer (if available)
- Device, browser, and operating system type
- Approximate geographic location (country only)
- Bot or preview indicators
- UTM campaign parameters present in the link URL (utm_source, utm_medium, utm_campaign, utm_term, utm_content)
1.3 IP Addresses
- IP addresses are never stored in raw form
- Before storage, IP addresses are truncated (IPv4 to /24, IPv6 to /48) and then salted-hashed, for analytics, abuse prevention, and security
1.4 Payment Information
Payment details are processed by third-party providers. We do not store full payment card information.
1.5 Link Destination Safety Scanning
To protect visitors from malicious or abusive links, our automated safety systems fetch the content of link destinations when links are created or edited, and periodically while they remain active. From that content we may collect and retain the destination page title, visible text excerpts, and the structure of any forms present, together with the resulting scan verdicts, as evidence for abuse prevention and enforcement.
Excerpts of destination page content may be processed by our AI safety provider (Anthropic) to classify the destination. This content relates to the linked page, not to visitors; it is used solely for safety classification.

- Provide and operate the Service
