Overview
ELVT – Hypertrophy by Design is committed to protecting your privacy. This policy explains how we handle your information when you use our website and mobile application.
Training Data & Offline-First Storage
Your workout data, progress logs, and personal training information are stored securely on your device by default. You may optionally back up your data to your personal cloud storage provider. We do not collect, sell, or monetize your personal training progress.
AI Hypertrophy Coach & Cloud Generative Features
When you choose to use the AI Hypertrophy Coach, AI Assistant, or the AI Microcycle Blueprint Builder, your specific training prompt and necessary contextual workout parameters (such as muscle groups, target volume, and exercise selection) are transmitted over an encrypted connection to cloud generative AI services — either directly (such as the Google Gemini API) or via our own serverless AI gateway hosted on Google Cloud, which forwards requests to external generative AI providers (currently Zhipu AI (Z.ai) GLM models and Groq). This gateway is protected by Firebase App Check device attestation and processes requests in memory only: your AI prompts are not stored in any database, and no persistent AI content logs are kept.
No personally identifiable information (such as your real name, email address, passwords, or payment credentials) is ever transmitted to these AI endpoints. Processing occurs in accordance with the Google AI Terms of Service and Google Privacy Policy, the Z.ai Terms of Use and Z.ai Privacy Policy, as well as the Groq Terms of Service and Groq Privacy Policy, where queries may be processed to generate responses and, depending on provider terms, used to improve and train generative models. All core workout tracking and local routines remain 100% functional offline without cloud AI interaction.
