Privacy Policy

1. Information we collect

Calculator use — nothing stored. All five calculators (tip, discount, sales tax, percentage, compound interest) run entirely in your browser using JavaScript. The numbers you enter are never sent to our servers, never logged, and never sold. Closing the tab erases them.

Contact messages. If you use our contact form, we receive the name, email address, topic, and message you provide so we can read and respond to your inquiry. These messages are stored securely and used only for correspondence and improving the site.

Basic technical logs. Like nearly every website, our hosting provider may log standard technical information (such as IP address, browser type, and pages visited) for security and reliability. We do not use this to build profiles of individual visitors.

2. How we use information

• To respond to messages you send through the contact page.
• To operate, secure, and improve the website.
• To comply with legal obligations.

We do not sell personal information. We do not share contact-form data with advertisers, data brokers, or affiliate partners.

3. Cookies and similar technologies

Smart Calculators Zone itself sets no advertising or tracking cookies for calculator use. If we introduce privacy-respecting, aggregated analytics in the future, this policy will be updated first. Third-party sites you visit through outbound links (including affiliate/partner links) operate under their own cookie and privacy policies — please review them on those sites.

4. Affiliate and outbound links

Some links on this site — primarily on the Money Tools & Resources page — are affiliate links. Clicking one takes you to a third-party retailer that may set its own cookies or collect its own data under its own policy. We do not receive your personal information from those clicks beyond aggregate referral reporting. See our Affiliate Disclosure.

5. Children’s privacy

Smart Calculators Zone is a general-audience educational website and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it promptly.

6. Your rights and choices

You may request access to, correction of, or deletion of personal information you have sent us (such as a contact message) by emailing hello@smartcalculatorszone.com with the subject “Privacy request.” We will respond within a reasonable timeframe. Because calculator inputs never leave your browser, there is nothing to request or delete for calculator use.

7. Data security and retention

We use reasonable administrative and technical safeguards to protect stored messages. Contact messages are retained only as long as needed to handle your inquiry and improve the site, then deleted or anonymized. No method of transmission or storage is perfectly secure, so please never send sensitive data such as account numbers or passwords.

8. Changes to this policy

We may update this policy as the site evolves. Material changes will be reflected in the “Last updated” date above. Continued use of the site after changes constitutes acceptance of the updated policy.
