Privacy Policy

Last updated: October 2026

Who we are

Arnhue is a clarity tool that helps you think through what is stuck. It is not therapy, not coaching, and not a substitute for professional mental health support. It is currently in beta.

What we collect

We collect the following data when you use Arnhue:

• ·Your email address -- used for login and to contact you about your account
• ·Your reflection content -- the messages you send and receive during sessions
• ·Session metadata -- when sessions started and ended, patterns identified
• ·Feedback you provide -- ratings and notes after sessions

Besides your reflections, we record how you use Arnhue: onboarding answers, ratings, in-app events, and coarse device and referrer information on arrival. Arnhue itself does not record IP addresses or location.

You can use Arnhue without an email. That account has 25 messages and one reflection. When you save your map with your email, it's the same account and the same data. Anonymous accounts that are not saved with an email are deleted after 30 days without activity.

How we use your data

• ·To provide the Arnhue service and improve your experience across sessions
• ·To identify patterns in your thinking over time -- this is the core product feature
• ·Emails we send: a welcome email when you save your map; check-in emails only if you opt in, with a switch in Settings and an unsubscribe link in every email; a confirmation when you delete your account; and a deletion notice to the founder containing counts and the account id
• ·We do not sell your data to third parties
• ·We do not use your reflections to train AI models

If you leave a reflection open, it closes after ten minutes. If there is no summary yet and enough has been said, one is written. Your map is rebuilt automatically from your patterns.

AI and your data

Arnhue uses an Anthropic model to power reflections. Your reflections are processed by Anthropic's API. Anthropic does not use API conversations to train their models. You can read Anthropic's privacy policy at anthropic.com.

We use Anthropic's API to process your reflections. Your messages, together with the context Arnhue keeps for you (your patterns, last summary and map), are sent to Anthropic to generate replies. Nothing that identifies you is sent. Anthropic's privacy policy governs this processing. Your reflections are not used to train AI models.

Data storage

Your data is stored in the European Union using Supabase. The app is hosted by Vercel, emails are sent through Resend, and voice notes are transcribed by Gladia (signed-in users only). Voice input in a reflection uses your browser's own speech service. We take reasonable technical measures to protect your data. Beta data will be deleted when the beta ends unless you explicitly choose to keep it.

Your rights

Under GDPR you have the right to:

• ·Access your data -- you can export your reflections from your settings
• ·Delete your data -- you can delete individual reflections from the Reflections page, or your entire account from settings
• ·Withdraw consent -- you can delete your account at any time
• ·Data portability -- your data is available as JSON export

When you delete your account, your reflections, patterns and map are deleted. Only anonymous usage counts (such as how many sessions and patterns), with no link to you, are retained. Copies of emails already sent to you remain with our email provider.
