You agree not to use Synheart for critical health or medical decisions.

Some Synheart apps include AI features ("Syni" and related AI-assisted insights). By using them, you agree to the terms in this section.

6.1AI Output Is Assistive, Not Authoritative

AI-generated insights, summaries, and answers are probabilistic and may be inaccurate, incomplete, or out of date. They are provided for general informational and self-reflection purposes only.

6.2Not Medical or Clinical Advice

Synheart AI does not diagnose, treat, or provide medical, psychological, or clinical advice. Do not rely on it for decisions affecting your health or safety. The Health & Safety Disclaimer in these Terms also applies.

6.3Your Responsibility

You are responsible for evaluating and verifying AI output before acting on it, and for not submitting content you are not authorized to share.

6.4Third-Party AI Processing

When you enable cloud AI features, your inputs are processed by third-party AI providers as described in our Privacy Policy. On-device AI runs locally on your device and is not sent to those providers.

Your use of the Services is also governed by our Privacy Policy.

Key points:

• Raw biosignal data stays on-device unless you explicitly consent
• We do not sell your personal data
• We do not collect keystroke content (only timing)
• You may request deletion at any time

If you use SDKs or APIs:

• You are responsible for complying with data protection laws
• You may not store or transmit sensitive data without consent

If you use Synheart SDKs or APIs, you must follow our Developer Terms, including:

• Rate limits
• Attribution requirements (where applicable)
• Prohibited uses (surveillance, profiling, sensitive classification)
• Security obligations for data you collect

We reserve the right to revoke API access for abuse or misuse.

All Synheart content, models, embeddings, metrics, algorithms, SDKs, and materials are protected by intellectual property laws.

You may not:

• Copy, modify, or create derivative works
• Resell Synheart data, insights, or SDKs
• Train models directly on raw Synheart outputs unless permitted

Open-source components are licensed separately.

Some Services may require payment.

You agree that:

• Prices and features may change
• Subscriptions renew automatically unless canceled
• Refunds follow posted policies
• Taxes may apply depending on your location

You can cancel at any time via your account settings.

We may suspend or terminate your access if:

• You violate these Terms
• We are required by law
• We discontinue a Service

You may stop using Synheart at any time.

Upon termination, your right to use the Services ends immediately.

Synheart is provided on an "as is" and "as available" basis.

We do not guarantee:

• The Services will be uninterrupted
• Metrics will always be accurate
• Data streams from wearables will always sync

We may update, remove, or modify features at any time.

To the maximum extent permitted by law:

Synheart is not liable for:

• Loss of data
• Health outcomes based on insights
• Indirect, incidental, or consequential damages
• Delays, interruptions, or system failures

Our total liability will not exceed the amount you paid in the past 12 months.

You agree to defend and indemnify Synheart from claims or damages arising from:

• Your misuse of the Services
• Your violation of these Terms
• Your use of SDKs or APIs to collect user data
• Third-party claims related to your applications

We may modify these Terms at any time.

If changes are significant, we will notify you.

Continued use of the Services after changes constitutes acceptance.

These Terms are governed by the laws of:

• British Columbia, Canada (if you operate as Synheart Technologies Inc.), or
• The relevant jurisdiction of your registered business entity

Disputes will be resolved in the courts of the same region.
