Privacy Policy

This policy explains what information may be collected when you use Stamp Calculator (“we,” “our,” or “this site”) and how it is used. We keep things straightforward and avoid collecting more than we need to run a small, free utility website.

What we collect

You do not need an account to use the calculator. The inputs you enter (weight, envelope size, and similar options) are processed in your browser to show results; we do not ask you to submit that information to us as a form of personal data for storage on our servers.

We may collect basic usage data through Google Analytics. That can include general information such as which pages were viewed, approximate region, device type, browser type, and how people move through the site. This helps us understand whether the site is working well and which content is most useful.

Like many websites, we use cookies and similar technologies. Cookies are small files stored on your device that help remember preferences, support analytics, and (if we enable them) allow advertising partners to measure or serve ads in line with their own policies.

How we use data

Information from analytics is used to improve the website experience—for example, fixing confusing pages, seeing which tools are popular, and understanding load patterns. We also use it to analyze traffic so we can maintain performance and plan updates responsibly.

We do not sell your personal information. We use data in ways that are typical for operating and improving a public informational site.

Third-party services

Google Analytics processes usage data according to Google's terms and privacy policy. You can learn more in Google's documentation about how Analytics works and what controls exist for users.

In the future we may display ads through networks such as Google AdSense or other providers. Those services may use cookies or similar tools to show relevant ads, limit how often you see an ad, and measure performance. Their use would be governed by each provider's policies, not by this page alone.

Your choices

You can disable or limit cookies through your browser settings. Many browsers let you block third-party cookies, delete existing cookies, or browse in a private mode. Keep in mind that blocking some cookies may affect how certain features or analytics behave.

You can also use industry opt-out tools where available (for example, tools offered by ad or analytics providers) in addition to browser controls.

Children

This site is a general-purpose postage planning tool. It is not directed at children under 13, and we do not knowingly collect personal information from children for marketing purposes.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the date or description on this page. Continuing to use the site after changes means you accept the updated policy.
