Privacy Policy
Last updated: 2026-03-31
1. Who We Are
MaiEcho is an AI emotional guidance companion operated by 鍛澄心智科技有限公司 (Taiwan).
- Website: maiecho.ai
- Contact: hello@maiecho.ai
2. AI Transparency
MaiEcho uses AI technology (Anthropic Claude) to generate responses. MaiEcho is not a therapist, counselor, or medical professional. It does not diagnose, treat, or provide medical advice.
If you are in crisis:
- Taiwan: 安心專線 1925 / 生命線 1995
- International: findahelpline.com
3. Conversation Storage — Notice of Update
We are updating our privacy disclosures to more accurately describe how your conversations are processed and stored. While the updated policy is being prepared, please contact hello@maiecho.ai for questions about how your data is handled.
In the interim:
- Conversations are processed by Anthropic Claude (US) under their commercial API terms, which by default exclude API data from being used to train general models.
- Conversations are stored on our backend (Supabase, US) for service continuity. They are not used for training general models or for marketing. Specific access may occur for: safety-critical content (such as crisis detection), your support requests, or legal compliance.
- You may request deletion of your data by emailing hello@maiecho.ai. We will acknowledge requests within 5 business days and complete deletion within 14 days of acknowledgment.
4. What We Do Collect
To improve service quality, we collect anonymous usage data:
a) Session analytics:
- Session duration, message count, general topic keywords, browser language
b) Message quality data:
- The full content of each message (linked to a random device identifier, not your name or email)
c) Feedback data:
- When you give feedback (thumbs up/down), the related conversation excerpt (up to 2,000 characters) is recorded
d) Technical data:
- Response timing, error codes (no message content)
5. Third-Party Services
Your messages are processed by:
- Anthropic (AI responses, US) — does not retain or use data for training under commercial API terms
- Supabase (data storage, US)
- Cohere (knowledge search ranking, US) — receives search queries only, not full messages
- Vercel (frontend hosting) / Railway (backend hosting) — no user data stored
6. Cross-Border Data Transfer
MaiEcho is operated from Taiwan. Anonymous analytics data is processed in the United States through our sub-processors listed above.
7. What We Do NOT Do
- Sell or share your data with third parties
- Use your conversations to train general AI models. The pseudonymous quality data described in Section 4 is used to improve the service, not to train external models.
- Use advertising trackers or cookies
- Collect names, emails, or personal identifiers (unless you create an account)
8. Your Rights
