Privacy Policy

01 Information We Collect

Our calculators, including the Profit Margin Calculator, run entirely in your browser. The numbers you enter — cost, selling price and similar figures — are never sent to our servers or stored by us. They exist only on your device while you’re using the page.

We do collect a small amount of information in the following cases:

• Contact form submissions — if you email us or use a contact form, we receive the name, email address and message you provide, so we can reply to you.
• Basic usage analytics — standard, aggregated information such as pages visited, approximate location (country or region), device type and browser, used to understand how the site is used.

02 How We Use Information

Any information we do collect is used only to:

• Respond to messages sent through our contact form or email
• Understand which tools and pages are useful, so we can improve them
• Maintain the security and reliability of the site

We do not sell, rent or trade personal information to third parties.

03 Cookies & Analytics

Bustech.site may use a small number of cookies or similar technologies for basic, privacy-respecting analytics — for example, to count visits without identifying you personally. These do not track you across other websites, and no account or sign-in is required to use any calculator on this site.

04 Third-Party Services

We may rely on third-party services for hosting, email delivery and analytics. These providers only receive the minimum information necessary to perform their function, and are expected to handle it in line with their own privacy policies.

05 Data Retention

Calculator inputs are never stored, so there is nothing to retain from your use of the tools themselves. Messages sent through our contact form are kept only as long as needed to respond to your enquiry and for a reasonable period afterward, then deleted.

06 Your Rights

Depending on where you live, you may have the right to ask what personal information we hold about you, to request a correction, or to ask us to delete it. Since we collect very little personal information in the first place — mainly what you choose to send us directly — most requests can be resolved quickly by contacting us.

07 Children’s Privacy

Bustech.site is intended for general business and professional use and is not directed at children. We do not knowingly collect personal information from children.

08 Changes to This Policy

We may update this policy from time to time as the site evolves. Changes will be posted on this page with an updated “last updated” date above.

09 Contact Us

If you have any questions about this policy or how your information is handled, reach out any time.
