Privacy Policy

Last updated: May 20, 2026

Lantus Dosing Calculator takes your privacy seriously, especially because the Lantus dosing calculator involves health-related inputs. This page explains exactly what we do and do not collect, and how the information you enter into the calculator is handled.

What we do not collect

Using the Lantus dosing calculator does not require an account, an email address, or any personal identifier. Your body weight, fasting glucose reading, current insulin dose, and diabetes type are processed entirely in your browser. They are never sent to a server, never stored in a database, and never logged.

Because the inputs never leave your device, this site does not maintain a medical record, does not receive Protected Health Information under HIPAA, and does not operate as a covered entity or business associate.

Local storage

The calculator may save your last-used inputs to your browser's local storage so the form remembers your body weight and current dose between visits. This data stays on your device. You can clear it at any time from your browser settings, or by using the Reset button in the calculator.

Privacy-respecting analytics

We use Cloudflare Web Analytics to understand aggregate traffic patterns. This service does not set cookies, does not fingerprint visitors, and does not track individuals across sites. It records page views, referrers, and country-level location for aggregate reporting only.

Advertising

Some pages display advertising through Google AdSense. Google may set cookies to serve ads based on your prior visits to this or other sites. To control personalized advertising, visit Google Ad Settings or opt out of third-party vendors at aboutads.info. We do not share any calculator inputs with advertising partners.

Email correspondence

If you email us at the address below, we retain your message only long enough to respond. We do not add email addresses to a mailing list and do not send newsletters.

Your rights under GDPR and CCPA

Because we do not collect personal data through the calculator, most GDPR and CCPA rights (access, rectification, deletion, portability) do not apply to us directly. They do apply to any data collected by Google AdSense and other embedded services on our pages, and those rights can be exercised through the respective provider.

California residents can learn more about their rights under the CCPA at the California Attorney General's CCPA page.

Children

This site is intended for use by adult patients, caregivers, and healthcare professionals. We do not knowingly collect information from anyone under 13. Pediatric insulin dosing should always be managed by a pediatric endocrinologist, not through an online calculator.

Changes to this policy

If we make meaningful changes to this policy, we will update the date at the top of the page and note the substantive change. We do not send notifications about policy updates, so we encourage anyone who relies on this site to review this page periodically.
