Privacy Policy
Last updated: October 2024 · 100% Client-Side Architecture
1. Data Collection
Peptide Calculator Suite performs 100% client-side calculations. All reconstitution arithmetic, dose volume derivation, syringe unit conversion, and result display occur entirely within your web browser using JavaScript. No calculation inputs, results, or personal data are transmitted to, processed by, or stored on any external server at any time. We do not collect, process, share, sell, or monetize any personal information, health data, browsing behavior, or usage patterns.
2. Local Storage
The application may optionally use your browser's local storage (localStorage API) to persist your theme preference (light or dark mode) and, if you choose to save a protocol, your calculator inputs. This data is stored exclusively on your device, never transmitted over the network, and never accessible to Peptide Calculator Suite or any third party. You can clear this data at any time through your browser's settings by clearing site data for this domain, or by using the application's built-in reset functionality.
3. Analytics
We may use privacy-focused, cookie-free analytics (such as Plausible Analytics) to understand aggregate traffic patterns, page views, and referral sources. Plausible does not use cookies, does not collect personal data, does not track individual users, and is fully compliant with GDPR, CCPA, and PECR without requiring consent banners. No personally identifiable information is processed or stored by our analytics provider. If analytics are enabled, only anonymized, aggregate statistics (such as page view counts and country-level geographic data) are collected.
4. Cookies
Peptide Calculator Suite does not set, read, or rely on any HTTP cookies. We do not use cookie-based tracking, session cookies, authentication cookies, or advertising cookies. No consent banner is required because no cookies are deployed.
5. Third-Party Services
Web fonts are loaded using Next.js's built-in font optimization system, which downloads font files at build time and serves them from the same domain as the application. No external font loading requests are made from your browser to third-party servers at runtime. We do not integrate any third-party advertising networks, social media trackers, pixel tags, or behavioral analytics platforms.
6. Your Rights
Because we do not collect or store any personal data, there is no personal data to access, correct, delete, or export. If you have saved protocol data to localStorage, you have full control over that data through your browser settings. You may delete it at any time without contacting us. If you believe any data has been inadvertently collected, or if you have questions about this privacy policy, please contact us through our contact page.
7. Contact
For any privacy-related questions, concerns, or requests, please reach out through our contact page. We are committed to transparency and will respond to all privacy inquiries promptly.
8. Changes to This Policy
We may update this privacy policy from time to time to reflect changes in our practices or applicable regulations. Any material changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
