About PT.FO

PT.FO is a small URL shortener with safety checks before links are created and again when links are used after a configured recheck period.

Shorten with pt.fo

javascript:(()=>{const f=document.createElement('form');f.method='POST';f.action='https://pt.fo/result';const i=document.createElement('input');i.type='hidden';i.name='url';i.value=location.href;f.appendChild(i);document.body.appendChild(f);f.submit();})();

Safety Checks

Some URLs will not be shortened. PT.FO blocks known shorteners and redirectors, checks for unsafe destinations, and avoids private or local network targets.

If a link is later flagged as risky, PT.FO shows a warning page instead of redirecting and does not display the full target URL.

Privacy Notes

PT.FO stores submitted URLs so short links can redirect. It also stores safety-check outcomes and limited diagnostic records.

The app records client activity using hashed IP addresses, IP prefixes, user agents, and report email addresses. Raw IP addresses are not stored in the application database, but web server access logs may contain client IP addresses, paths, user agents, status codes, and timestamps.

When safety checks are configured, checked URLs or domains may be sent to external safety services for evaluation.
