Privacy Policy

Last updated: 2026-07-14

The short version

OverlapCheck is a free analysis tool. You can use every calculator and dashboard on this site without an account, without signing in, and without giving us any personal information. We collect data in exactly one place: if you set up a Smart Alert, we need an email address to send it to.

What we collect

Smart Alerts. When you submit a monitor request, we store the email address you provide, the monitoring condition you wrote, the time of submission, the page you submitted from, and a coarse country code. We use this solely to set up and deliver the alert you asked for, and to reply to you about it.

Server logs. Our hosting provider (Cloudflare) processes standard request metadata (IP address, user agent) to serve the site and protect it from abuse. We apply light rate-limiting on form submissions using a short-lived, automatically-expiring counter.

Social media accounts. If we operate integrations that post OverlapCheck content to social platforms (such as X or TikTok), those integrations access only our own brand accounts. We do not collect, read, or store data about other users of those platforms.

What we don't do

We don't sell or share your data with third parties. We don't run third-party advertising or tracking pixels. We don't build profiles of visitors. We don't require accounts. Portfolio inputs you type into the calculator are processed in your browser and are not transmitted to us.

Data retention and deletion

Alert records are kept while your monitor is active. Email overlapcheck@agentmail.to at any time to see or delete what we hold about you; deletion requests are honored within 7 days.
