What we collect

• • Aggregated usage analytics (page views, device type, anonymous events).
• • Non-identifying technical logs to keep the site fast and secure.
• • Optional data you email us (support requests, feedback). We only keep what we need to answer you.

What we do not collect

• • No personal accounts, passwords, or payment info.
• • No input values from calculators are stored with personal identifiers.
• • No selling or renting of data—ever.

Cookies and analytics

We use privacy-conscious analytics to understand performance and reliability. Data is aggregated and anonymized. You can block cookies in your browser; the calculators will still work.

Data sharing

We share data only with essential service providers (hosting, analytics, security) under strict contractual obligations. They cannot use your data for their own purposes.

Data retention

Support emails are retained only as long as needed to resolve your request. Aggregated analytics may be kept longer to track product performance trends.

Your choices

• • Use tracker blockers or disable cookies; core calculators remain functional.
• • Email us to delete prior communications you’ve sent.
• • Opt out of marketing emails at any time. We rarely send them and only with explicit opt-in.

Security

Data is transmitted over HTTPS. Access to infrastructure is restricted, audited, and requires authentication. We regularly update dependencies and monitor for vulnerabilities.

Children’s data

CalculatorLine.com is not directed to children under 16. We do not knowingly collect personal data from children. If you believe a child has provided data, contact us to remove it.

Changes to this policy

We update this policy when we ship material changes. The “Last updated” date will reflect the latest version.
