Privacy Policy

Last Updated: September 28, 2026. This policy outlines our data handling practices, client-side storage architecture, and privacy commitments.

1. Zero Registration & Account Requirement

FreePeptideCalculator.com is designed as a friction-free, public utility. We do not require account registration, login credentials, or email submission to access any of our reconstitution calculators, blend tools, or guide articles. We do not collect or maintain user account profiles or email subscriber databases.

2. Client-Side Data Storage (Save-a-Dose Feature)

When you use our interactive "Save Dose" card feature to store custom reconstitution parameters (e.g., peptide mass, BAC water volume, desired dose), this data is stored exclusively inside your web browser’s `localStorage` API.

This data is strictly client-side. It resides on your local device and is never transmitted to, stored on, or processed by our web servers or any external third-party servers. Clearing your web browser's cache or local site data permanently deletes your saved dose cards.

3. Web Analytics & Third-Party Services

[ANALYTICS PROVIDER PLACEHOLDER]

Project Owner Action Required: Insert your actual analytics provider configuration here. For example: "We use Plausible Analytics / Cloudflare Web Analytics / Google Analytics 4 to measure aggregate traffic (page views, country-level geography, browser device category). No personal data or IP addresses are collected or tracked."

4. User Rights & Data Requests

Because we do not store personal data on external servers, we hold no user profiles to export or delete. However, if you have questions regarding data privacy, cookie preferences, or wish to submit an inquiry under applicable privacy regulations (such as GDPR or CCPA), you can contact us via our Contact Page.
