1. Introduction

Smart404 ("we", "our", or "us") helps site owners turn dead‑end 404 pages into useful navigation pathways with a lightweight AI‑powered script. Protecting your privacy is central to our mission. This Privacy Policy explains how we collect, use, disclose and safeguard your information when you install or interact with Smart404, visit our website, or communicate with our team.

By using Smart404 you agree to the practices described below. If you disagree with any part of this Policy, please do not use the service.

  • Website analytics – aggregate page‑view and usage statistics collected via first‑party cookies.

2.3 Cookies & Similar Technologies
