WhyIsMyEmailLate is built on a simple, non-negotiable principle: your data is yours. This Privacy Policy explains exactly what information we do and do not collect, how the tool operates, and what rights you have as a visitor. We have designed every aspect of this site to minimize data collection — in most cases, to zero — because the only information we need from you to provide our service is the email header text you paste directly into the tool, and that text never leaves your device.
WhyIsMyEmailLate collects no personal data. We do not operate any backend server that receives requests from the analysis tool. We do not log your IP address in connection with tool usage. We do not collect your name, email address, location, or any identifying information as part of using this service. There is no account creation, no sign-up form, and no login. The tool is entirely free and requires no registration of any kind.
All analysis on WhyIsMyEmailLate runs entirely in your web browser using client-side JavaScript. When you paste raw email headers and click Analyze, the parsing, timestamp normalization, delta calculation, and narrative generation all execute locally on your device. The processed output — hop timelines, latency charts, transit narratives — is rendered directly in your browser window and is never transmitted to any external server, API, or third-party service. This is not merely a policy commitment; it is a technical reality. There is no server endpoint to receive your data because none exists in our architecture.
WhyIsMyEmailLate includes an optional PII (Personally Identifiable Information) masking feature. When enabled, this feature uses client-side regular expressions to replace email addresses and IP addresses in the displayed output with anonymized placeholders. This operation runs entirely within your browser. It does not modify, delete, or transmit the original data you have pasted. It only changes what is visually rendered on screen, allowing you to safely share screenshots or export the analysis report without exposing sensitive routing information.
WhyIsMyEmailLate does not use tracking cookies, session cookies, or any first-party cookies for analytics or personalization. We do not use Google Analytics, Facebook Pixel, or similar behavioral tracking technologies. If Google AdSense advertising is active on this site, Google may set its own advertising cookies in accordance with Google's Privacy Policy, available at policies.google.com/privacy. You can opt out of Google's personalized advertising at any time by visiting adssettings.google.com. For visitors in the European Union, a consent management banner will appear on first visit to obtain your explicit consent before any advertising cookies are set, in accordance with GDPR requirements.
This site may display advertisements served by Google AdSense. Google AdSense uses cookies and similar technologies to serve ads based on your prior visits to this and other websites. These advertising cookies are set by Google, not by WhyIsMyEmailLate. No data you enter into the email header analysis tool is shared with Google or used for advertising purposes. Google AdSense operates independently of the analysis functionality. For more information on how Google uses data when you visit sites that use Google advertising services, visit google.com/policies/privacy/partners.
WhyIsMyEmailLate is hosted on Vercel. When you visit this site, Vercel's infrastructure processes standard HTTP request data — including your IP address and browser user agent — as part of serving the web page. This is standard web hosting behavior and is governed by Vercel's Privacy Policy at vercel.com/legal/privacy-policy. Vercel may retain server access logs for security and operational purposes. WhyIsMyEmailLate does not access, analyze, or store these logs for any purpose beyond what Vercel's platform provides by default.
Because WhyIsMyEmailLate does not collect personal data, the practical scope of data subject rights (access, erasure, portability, restriction, objection) under GDPR and CCPA is very limited. There is no personal data held by WhyIsMyEmailLate to access, erase, or port. If you have questions about advertising data held by Google, you should contact Google directly or use the tools available at myaccount.google.com. If you are a California resident and have questions about our data practices, you may contact us at the email address below. We will respond within 45 days as required by the CCPA.
WhyIsMyEmailLate retains no user data because we collect none. All processing is ephemeral and browser-local. When you close your browser tab, the parsed analysis results are discarded. Nothing is written to any persistent store on our end. If you use your browser's local storage or cache, you can clear that data at any time through your browser's settings — it is stored only on your own device and is not accessible to WhyIsMyEmailLate.
WhyIsMyEmailLate is not directed at children under the age of 13, and we do not knowingly collect any personal information from children. If you believe a child under 13 has provided us with personal information, please contact us immediately so we can take appropriate action.
We may update this Privacy Policy from time to time to reflect changes in our practices, legal requirements, or the features of our service. When we make material changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of the site after any change constitutes your acceptance of the updated policy.
If you have questions or concerns about this Privacy Policy or our data practices, please contact us at privacy@whyismyemaillate.com. We will respond to all legitimate inquiries within a reasonable timeframe.
