Plain-English first. Legal second.

The short version

WiseHeart is a paying-subscriber business. We make money from your subscription, not from your data. We don't sell, rent, or trade it.

• What we collect: bracelet readings (the calm signals from the wrist sensor), your labels and notes, your Coach conversations, and basic account information. Optional: sleep and activity context from Apple Health or Google Fit if you connect them.
• How it's stored: under your account, encrypted in transit and at rest. We never sell it or use it for advertising.
• Where it goes: encrypted in transit and at rest. Processed on-device where possible.

What we never do

• Sell, rent, or trade your data.
• Use it for advertising.
• Share individual readings with your employer.
• Share your Coach conversations with a coach you've granted access to — they see calm trends and only the moments you chose to share, never conversation content.

Aggregate stats

We may compute anonymized aggregates across the user base for product improvement — for example, how often a particular kind of nudge tends to help. No aggregate ties back to you.

Your controls

• Export. Email hello@wiseheart.me and we provide a copy of your data. An in-app export is on the roadmap.
• Delete. One button in the app. Your account closes and your data is erased immediately. Some anonymized aggregate statistics may remain — not identifying you.
• Pause. Stop sharing without losing your history.
• Sharing with coaches or therapists. Opt-in only. Granular permissions. Revocable at any time.

Crisis-signal disclosure

Your Coach conversations are private. The companion is designed to point you to professional support resources when a conversation suggests you need more than everyday stress help. No human reads your conversations.

Children's privacy

WiseHeart is not for users under 18. We don't knowingly collect data from anyone under that age.

Compliance posture

We work toward GDPR and CCPA compliance. Where the two regimes differ, we apply whichever protection is stronger as a default. If you're in the EU, U.K., or California and want to exercise a specific right, email hello@wiseheart.me and we'll respond within the legally required window.

Third-party processors

We disclose every third party that touches your data:

• Firebase — authentication, real-time database, and storage.
• Polar — hardware partner and on-device SDK for the bracelet.
• Language-model providers — Coach conversations are processed by language-model providers under strict data-use terms. They are contractually prohibited from training models on your data.

Privacy contact
