Terms of Service

Last Updated: October 26, 2026

Welcome to Helibrain! These Terms of Service (“Terms”) govern your use of Helibrain, including the mobile app, the helibrain.com website, and their features such as questionnaires, habit tracking, the AI coach, the Guided plan, and any other functionality provided.

By accessing or using Helibrain, you agree to be bound by these Terms. If you do not agree to these Terms, you must discontinue using the app.

1. Acceptance of Terms

You must:

Be at least 18 years old or meet the age of majority in your jurisdiction.
Read, understand, and accept these Terms and our Privacy Policy.

If you disagree with any part of the Terms or the Privacy Policy, you may not access the service.

2. User Responsibilities

You agree to:

Use the app lawfully and in accordance with these Terms.
Not misuse the app or engage in any activity that disrupts or harms the services.
Keep your account credentials secure and notify us immediately of unauthorized access.

Prohibited actions include:

Copying, modifying, or reverse-engineering the app.
Reselling or redistributing the app or its features.
Uploading harmful or illegal content.
Copying, scraping or collecting content from Helibrain in bulk by automated means (such as bots, crawlers or scrapers), or creating accounts by automated means, except through interfaces we provide or authorize for that purpose. Using an assistant or agent to access your own account for your own personal use is allowed.

2A. Intellectual Property

All content, features, and functionality of Helibrain are owned by us and are protected by international copyright, trademark, and other intellectual property laws.

3. Purpose of the Service (Non-Medical)

The Helibrain service is provided for educational purposes only. It is not a substitute for medical advice, diagnosis, or treatment.

Do not use Helibrain for medical decisions without consulting a licensed healthcare provider.
Recommendations and insights provided (e.g., well-being suggestions, habit guidance, meal plans) are general and non-diagnostic.
The Guided plan and its daily tasks are general wellness guidance, not medical treatment. Stop any activity that causes pain or feels unsafe, and talk to a healthcare provider if you have a health condition.
Cognitive test results and trends are for educational purposes only and are not medical diagnostics.
Health metrics read from Apple Health or Health Connect (such as sleep, HRV, and resting heart rate) and any recovery status derived from them are informational only — they are not medical measurements, diagnoses, or alerts, and must not be used to make medical decisions.

4. Features of the Service

4.1 Questionnaire: You may answer questions to receive tailored suggestions.

4.2 Habit Tracking: Track recommended or custom habits, with the days, time, and amount (for example, "15 minutes") you choose, reminders, and progress.

4.3 Nutrition Logging: Log meals via photos/text and receive scores/tips.

4.4 AI Coach Chat: Interact with an AI-powered brain health coach that can answer questions, log meals, track habits, set calorie goals, discuss your cognitive assessment results, and provide personalized food recommendations on your behalf. You can type or use voice input (your speech is turned into text that you can edit before sending). The coach can add or change habits, habit schedules, and reminders when you ask it to, or after you confirm a change it proposes. The coach may ask you questions with answer buttons. The AI coach is powered by third-party AI services (third-party AI service providers). AI responses are generated automatically and may not always be accurate or complete — they are for informational and educational purposes only and do not constitute medical, nutritional, or professional advice. Always verify important information and consult a healthcare provider for medical decisions. The number of messages you can send each day is described in Section 7.

4.5 Guided Plan (subscription): A daily plan built with the AI coach from your goal and your answers to a few questions, including whether you work night or rotating shifts. Each day you get one main task; the plan adjusts it every day based on what you did (done, smaller version, or skipped), your check-ins and ratings, and the pace you ask for. A weekly review looks back at your week and suggests next steps. The coach sends you short reminders ("nudges") at a time it picks from when you usually use the app and from your reminder settings; you can change the time, ask for fewer, or turn them off. While the plan is active, the coach's messages replace your habit reminders; your earlier reminder settings are saved and restored if the plan ends. The coach changes your plan only when you ask it to or after you confirm a change it proposes. Subscription terms are in Section 6.

4.6 Cognitive Assessments: Take short cognitive tests (reaction time, self-control, working memory, reasoning, and creativity) and view your results and trends over time. Cognitive tests and scores are for educational purposes only — they are not medical diagnostics, do not produce an IQ score, and must not be used for clinical, employment, or other evaluative decisions. Individual sessions naturally vary with factors such as sleep and fatigue. The creativity test is scored with the help of third-party AI services.

4.7 Health Data Integration: Optionally connect Apple Health (iOS) or Health Connect (Android) to see your sleep, HRV, resting heart rate, steps, and workouts in the app, to have matching habits ticked automatically (you can untick them), along with a daily recovery status based on your own baseline, sleep/HRV trends, associations with your cognitive results, and a recovery contribution to your Brain Score. Access is read-only and controlled by the permissions you grant; you can disconnect at any time in Profile → Connections. Derived indicators (such as the recovery status) are heuristics computed from your own data — they are informational only and not medical advice.

4.8 Self-Experiments: Self-experiments are no longer offered as a separate feature. Data from experiments you ran before is kept in your account until you delete your account.

All processing is described in our Privacy Policy.

5. Account Creation and Termination

To use Helibrain, you must create an account with a valid email and password or register via Google or Apple Sign In.
You may delete your account at any time via the app or by contacting us.

We reserve the right to terminate or suspend your account without prior notice if you breach these Terms.

6. Subscriptions & Billing

The Guided plan costs $6.99 per month or $29.99 per year (US prices) and renews automatically until you cancel. To avoid being charged for the next period, cancel at least 24 hours before your current period ends, in your App Store or Google Play subscription settings.

(a) Guided plan. The Guided plan is an auto-renewing subscription billed by App Store (iOS) or Google Play (Android) to the store account you buy with. You can pay monthly ($6.99 every month) or yearly ($29.99 every year). You are charged when you subscribe; there is no free trial. Outside the US, the store shows the price in your local currency before you buy.

(b) Automatic renewal. Your subscription renews automatically at the end of each period (every month or every year) for another period of the same length, unless you cancel at least 24 hours before the current period ends. The store charges your account for the renewal within the 24 hours before the period ends, at the current price (see (e) for price changes).

Google Play → Account → Payments & subscriptions (Android)
Settings → [Your Name] → Subscriptions (iOS)

After you cancel, the Guided plan stays active until the end of the period you've paid for. Deleting the app or your Helibrain account does not cancel billing.

(d) When the plan ends. If your subscription ends, you return to the free tier. Your plan and its history stay readable, and your saved reminder settings are restored.

(e) Pricing & taxes. Prices are shown in your local currency and may include taxes. We may change prices or plans; any change applies on your next renewal, with notice where required.

(f) Refunds. Purchases in the App Store or Google Play are processed by Apple or Google, and refunds follow their policies. To ask for a refund, contact the store you bought from: Apple at reportaproblem.apple.com, or Google Play through its refund help page (support.google.com/googleplay/answer/2479637). We can't issue refunds for store purchases ourselves.

(g) Purchases on helibrain.com (when available). Payments made on our website may be processed by a reseller acting as merchant of record. You can get a full refund within 14 days of a purchase or renewal by emailing hello@helibrain.com. You can cancel a website subscription at any time; it stays active until the end of the period you've paid for.

(h) Entitlements / Restore. A valid store receipt is required to unlock the Guided plan across devices. Use “Restore purchase” in the app to reactivate entitlements on a new device.

(i) Promotions. Intro offers and trials are at our discretion and may have eligibility limits to prevent abuse.

This doesn't affect your rights under applicable consumer law.

7. Free Tier, Guided Plan, and Coach Message Limits

Helibrain offers a free tier with limited access to certain features, including habit tracking, meal logging, and AI coach messages. Guided plan subscribers receive the Guided plan and expanded access to features as described within the app. Subscription terms are described in Section 6.

AI coach messages have a daily limit:

Free tier: 10 messages a day.
Paid Guided plan: a fair-use limit of 100 messages a day.

Messages you type or send by voice count toward the limit, and so do taps on suggested replies and answers to the coach's question cards, because each one gets a coach reply. Messages the coach sends on its own (such as your daily task, nudges, and weekly reviews) and taps on check-in cards don't count. Current limits are displayed within the app. We reserve the right to adjust free-tier limits at any time.

7A. Lifetime In-App Purchases

In addition to the auto-renewing subscription described in Section 6, we offer one-time non-consumable in-app purchases that grant permanent access to specific features. These purchases:

Are billed once by Google Play (Android) or App Store (iOS); no recurring charges.
Grant access forever to the unlocked feature on your Helibrain account.
Are restorable on any device where you sign in with the same Helibrain account, via "Restore purchase" in the app.
Are refunded according to the store's policies, as described in Section 6(f).

The currently offered lifetime purchase is:

Self-Guided unlock ($19.99, one-time; US price) — a one-time purchase that grants permanent access to every premium recommendation, in the app and in the coach. Which recommendations you see is shaped by your questionnaire answers and may evolve as we add new content or refine matching; the unlock covers every premium recommendation surfaced to you, now and in the future. Sold separately from the Guided plan; the Guided plan does not include this unlock, and this unlock does not include the Guided plan.

8. AI-Generated Content Disclaimer

The AI coach and the Guided plan use artificial intelligence to generate responses, daily tasks, nudges, and reviews. While we strive for accuracy, AI-generated content may contain errors, inaccuracies, or outdated information. The coach can add or change habits, schedules, and reminders when you ask it to or after you confirm; check these changes in the app, and change or remove anything that doesn't suit you.

You should:

Not rely solely on AI responses for health, dietary, or medical decisions.
Verify any important information independently.
Consult qualified professionals for medical, nutritional, or mental health advice.

We are not liable for actions taken based on AI-generated responses.

9. Limitation of Liability

To the fullest extent permitted by law:

Helibrain is provided “as is” and “as available” without warranties of any kind.
We make no guarantee regarding accuracy, completeness, or availability of the service.
We are not responsible for any:
Loss or damage arising from reliance on our recommendations.
Emotional distress caused by insights provided.
Indirect, incidental, or consequential damages (e.g., loss of data, profits, or personal harm).

Cap on Liability: Our total liability for claims arising out of your use of the service is limited to USD $3 or the amount you paid to use the service in the past 12 months, whichever is greater.

10. Third-Party Links

The app may include links to third-party websites or services. We are not responsible for their content, practices, or policies. Your use of such links is at your own risk.

11. Modifications to the Terms

We reserve the right to update or change these Terms at any time. Changes take effect upon posting the updated Terms in the app. You are responsible for reviewing the Terms periodically to stay informed.
