Privacy Policy
Our commitment to absolute data privacy, client-side state persistence, and zero tracking.
1. Client-Side State Persistence (Zero Server Logs)
PeptidePrecise is engineered as a privacy-preserving web application. All calculations, vial mass inputs, diluent parameters, saved reconstituted vial inventories, body map injection site logs, and cycle schedules are stored exclusively in your browser's local storage (localStorage). No calculation parameters or personal notes are transmitted to or stored on external database servers.
2. Zero Personal Data Selling or Monetization
We do not collect, aggregate, sell, or rent personally identifiable information (PII) to data brokers, ad networks, or third-party marketing vendors. You can use all calculator engines and reference features completely anonymously without registering an account.
3. Progressive Web App (PWA) Offline Capabilities
Because PeptidePrecise operates using static assets and client-side JavaScript islands, the web app can function entirely offline once cached. No active network connection is required to perform reconstitution stoichiometry or access stored vial logs.
4. Local Storage Clearing & Cache Control
You retain full control over your stored data. Clearing your browser cache or site data automatically erases all saved vials, injection logs, and custom preferences from your device.
5. Updates to This Policy
Any updates to our privacy architecture will be reflected on this page. Our core architectural constraint—storing data locally on your device rather than a remote server—remains permanent.
