Overview
Wellphases is a personal wellness companion for women navigating perimenopause and menopause. Your privacy is fundamental to our design — your health data stays on your device.
What Information We Handle
Stored locally on your device (never sent to our servers):
- Health information you share in conversation (symptoms, diet, sleep, mood, exercise, menstrual cycle)
- Extracted health patterns and data
- Your profile information (name, age, menopause stage)
Sent to AI service providers to generate responses:
- Chat messages you send to the AI assistant
How AI Responses Work
When you send a message, it is transmitted to Anthropic, Inc. (anthropic.com) to generate a response using their Claude AI model. Anthropic processes your message in real time to produce a reply and does not store your personal health data for their own purposes beyond what is necessary to service your request.
Anthropic is our third-party AI processor. Their privacy practices are governed by the Anthropic Privacy Policy at anthropic.com/privacy. By using Wellphases, you consent to your messages being processed by Anthropic in accordance with their privacy policy.
We do not operate any servers that receive or store your conversation content. The only external transmission of your data is to Anthropic for the purpose of generating AI responses.
Data Storage and Security
- All health data and chat history are stored locally on your device using encrypted storage
- We do not operate servers that store your personal health information
- We do not have access to your health data
Data Sharing
- We do not sell your data to anyone
- We do not share your data with advertisers or data brokers
- We do not use your data for marketing purposes
- The only third party that receives your data is Anthropic, solely for the purpose of generating AI responses as described above
Your Consent
Before sending any message to the AI assistant, Wellphases will ask for your explicit consent to transmit your messages to Anthropic for processing. You may withdraw consent at any time by discontinuing use of the chat feature.
Your Control Over Your Data
- Delete anytime: You can delete all your data from within the app at any time via Settings → Delete All My Data
- Uninstall: Removing the app removes all locally stored data
- Your data, your control — always
Law Enforcement
Since data is stored only on your device and encrypted, we have nothing to provide. Anthropic may have their own obligations under applicable law — refer to their privacy policy for details.
