Terms of Use

Last updated: June 18, 2026

By using LineProof, you agree to use the service only for lawful browser-based network diagnostics and personal or operational insight.

Measurement Disclaimer

LineProof reports browser-observed measurements from supported providers such as Cloudflare Speedtest and M-Lab NDT7. Results can vary due to Wi-Fi conditions, device load, browser scheduling, VPNs, routing, congestion, provider endpoint choice, and local network equipment.

No Guaranteed Service Level

LineProof is provided as an informational utility. It does not certify internet service quality, guarantee exact ISP billing speeds, or replace professional network testing equipment.

Acceptable Use

• Do not automate excessive speed tests or abuse third-party measurement providers.
• Do not use LineProof to attack, overload, probe, or disrupt networks.
• Do not misrepresent LineProof results as official regulatory findings.

Third-Party Providers

Measurements may rely on third-party provider systems. Their availability, endpoints, and data handling practices are governed by their own terms and policies.

Changes

These terms may be updated as LineProof changes. Continued use after updates means you accept the revised terms.
