Privacy Policy

Last updated: 2026.

This Privacy Policy explains what information MyDayStamp collects, how it's used, and the choices you have. We built this site around a simple principle: the dates and details you type into a calculator are yours, and we've deliberately kept our data footprint as small as possible.

What we collect

The calculators on MyDayStamp run entirely in your browser. Dates and other values you enter — a birthdate, a due date, a countdown target — are processed locally on your device using JavaScript and are never transmitted to or stored on our servers. We have no database of user-entered dates because we never receive them in the first place.

If you email us through the Contact page, we retain that correspondence (including your email address) only for as long as needed to respond to your message.

Analytics

We may use privacy-conscious analytics to understand aggregate traffic patterns — for example, which calculators are visited most, or which pages load slowly — which does not identify you individually. This helps us prioritize which tools to improve or build next.

Advertising

This site may display advertising served by third-party providers such as Google AdSense. These providers may use cookies or similar technologies to serve ads that are relevant to you based on your visit to this and other sites. You can control ad personalization through your browser settings or through adssettings.google.com.

We do not control how third-party ad networks use the data they collect independently through their own cookies — their practices are governed by their own privacy policies, not this one.

Cookies

Advertising and analytics providers may set cookies in your browser to support the functions described above. You can view, block, or delete cookies at any time through your browser's settings. Disabling cookies may affect how ads are personalized but will not affect the accuracy or availability of any calculator on this site.

Data retention

Because calculator inputs are never transmitted to our servers, there is nothing for us to retain or delete on that front — that data simply doesn't exist outside your own browser session. Contact form correspondence is kept only as long as reasonably necessary to address your inquiry.

Children's privacy

MyDayStamp is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in our practices or in applicable law. The "Last updated" date at the top of this page will reflect the most recent revision.
