1. Acceptance of Terms

By downloading, installing, or using the HelAI mobile application ("App") or visiting the website helai.app ("Website"), and by creating an account, you ("User", "you", "your") agree to be bound by these Terms of Service ("Terms") and our Privacy Policy.

If you do not agree to these Terms, do not use the Service.

These Terms form a legally binding agreement between you and Konstantin Yeftifeyev, operating as HelAI ("we", "us", "our", "HelAI"). "Service" refers collectively to the App, the Website, and all features and content provided through them.

2. Who We Are

Operator: Konstantin Yeftifeyev, a natural person operating as HelAI
Address: Taugul-1, house 57, Almaty 050001, Republic of Kazakhstan
Phone: +7 778 767 7555
Contact: [email protected]
Website: https://helai.app

HelAI is developed and operated by one individual, not by a company.

3. Description of the Service

HelAI is a mobile fitness coaching application that uses artificial intelligence and your device's camera to:

Analyze your exercise form in real time using on-device pose detection
Count repetitions automatically
Provide form correction feedback during workouts
Allow you to track and log workout sessions, sets, and repetitions
Display your personal records and fitness progress
Generate and manage workout programs
Set and track fitness goals
Integrate with Apple Health (iOS) and Google Health Connect (Android) to display health and recovery metrics
Optionally connect to Garmin smartwatches for enhanced tracking

The Service is provided "as is" for personal, non-commercial fitness and wellness purposes.

4. Eligibility and Age Requirements

4.1 Minimum Age

The Service is for adults only. You must be at least 18 years old to use it. By using the Service, you represent and warrant that you are 18 or older.

The Service is not directed to children, and we do not knowingly allow anyone under 18 to create an account. If we learn that an account belongs to someone under 18, we will delete it and the associated data.

We do not verify age. This requirement is a condition of the agreement, and the app stores carry a corresponding age rating.

4.2 If You Are a Parent or Guardian

If you believe a person under 18 is using the Service, contact us at [email protected] and we will remove the account and its data.

4.3 Capacity

By using the Service, you represent that you have the legal capacity to enter into this agreement in your jurisdiction.

5. Account Registration and Security

5.1 Registration

To access the full features of the Service, you must create an account using a valid email address or a supported third-party authentication provider (currently Google Sign-In and Apple Sign-In). You agree to:

Provide accurate, current, and complete registration information
Maintain and promptly update your account information to keep it accurate
Keep your authentication credentials confidential
Not share your account with any other person

5.2 Account Security

You are solely responsible for all activity that occurs under your account. If you suspect unauthorized access to your account, you must notify us immediately at [email protected].

We are not liable for any loss or damage arising from your failure to maintain account security, provided that we have fulfilled our security obligations described in the Privacy Policy.

5.3 One Account Per Person

You may not create multiple accounts for yourself. Each person may maintain only one account. We reserve the right to merge or close duplicate accounts.

6. Health, Safety, and Medical Disclaimer

Please read this section carefully. It contains important limitations regarding the nature of this Service.

6.1 Not a Medical Device

HelAI is not a medical device and has not been approved or cleared by any regulatory body (including the U.S. Food and Drug Administration, the European Medicines Agency, or equivalent bodies in other jurisdictions) as a medical device. It is not designed, manufactured, or marketed for use in the diagnosis, cure, mitigation, treatment, or prevention of any disease or medical condition.

6.2 Not Medical Advice

The information, guidance, feedback, and content provided by the Service — including AI form analysis, rep counting, readiness scores, and program recommendations — constitute general fitness information only and do not constitute medical advice, diagnosis, treatment, or a prescription of any kind.

The Service is not a substitute for:

Professional medical evaluation or diagnosis
Advice from a licensed physician, physiotherapist, or other healthcare provider
Professional coaching or personal training from a certified fitness instructor

6.3 Consult a Healthcare Professional

Before starting any exercise program, significantly changing your physical activity level, or using the AI coaching features of the Service, you should consult with a qualified healthcare provider, particularly if you:

Have or suspect you have any medical condition, injury, or illness
Are recovering from surgery or injury
Are pregnant or postpartum
Have cardiovascular, respiratory, orthopedic, or metabolic health conditions
Are taking medication that may be affected by exercise
Have not been physically active for an extended period

6.4 AI Feedback Limitations

The AI pose detection and form feedback feature has inherent limitations:

It operates based on visual analysis from a single camera angle
It cannot assess internal factors such as muscle fatigue, joint stress, or pain
It may not detect all form errors under all conditions (lighting, clothing, angle)
It may produce incorrect assessments in some situations
It is a supplementary tool, not a replacement for professional coaching

Do not ignore pain or discomfort during exercise. If you experience pain, dizziness, shortness of breath, chest pain, or other symptoms of distress during exercise, stop immediately and seek medical attention.

6.5 Assumption of Risk

You acknowledge that physical exercise involves inherent risks, including but not limited to:

Muscle soreness, strain, or injury
Cardiovascular events
Falls or accidents
Aggravation of pre-existing conditions

By using the Service, you voluntarily assume these risks and agree that HelAI and its operator are not responsible for any injury, illness, or other harm that may result from your use of the Service or your participation in physical exercise.

6.6 Health Data Display

Health data displayed in the app (sleep, heart rate, steps, weight, etc.) is read from Apple Health or Google Health Connect for informational purposes only. This data is not medically validated and should not be used for clinical decision-making.

7. Permitted and Prohibited Use

7.1 Permitted Use

You may use the Service for:

Personal, non-commercial fitness tracking and coaching
Logging your own workout sessions and tracking personal progress
Using the AI camera feature to receive form feedback on your own exercise performance
Creating and managing your personal workout programs and goals

Reverse engineer the App, decompile or disassemble its source code, or attempt to derive the underlying algorithms, including the AI models
Scrape, crawl, or extract data from the Service using automated tools
Impersonate another user or any person
Access the Service using unauthorized means, including bots, scrapers, or scripts

Transmit any malware, viruses, or other harmful code
Use the Service for any commercial purpose without our prior written consent
Use the AI coaching feature as a basis for professional medical, physiotherapy, or clinical advice to others
Violate any applicable local, national, or international law or regulation

We reserve the right to suspend or terminate accounts that violate these prohibitions.

8. AI Features and Limitations

8.1 On-Device Processing

The AI pose estimation feature operates entirely on your device. No camera frames, video, or pose data are transmitted to our servers or to any third party. The machine learning model is downloaded to your device and runs locally.

8.2 No Warranty of Accuracy

We make no warranty that the AI form analysis, rep counting, or exercise identification features will be accurate under all conditions. Performance may vary based on:

Lighting conditions
Camera angle and distance
Clothing worn
Device processing capabilities
The specific exercise being performed

8.3 Continuous Improvement

We may update the AI models periodically to improve accuracy. Models are downloaded on demand from the app stores' own delivery services and do not involve transmission of your data.

9. Intellectual Property

9.1 Our Rights

The Service, including the App, Website, AI models, exercise database, program templates, design, software, trademarks, logos, and all other content, is owned by or licensed to HelAI and is protected by copyright, trademark, and other intellectual property laws.

You are granted a limited, non-exclusive, non-transferable, revocable license to use the App on your personal device(s) for personal, non-commercial purposes in accordance with these Terms.

This license does not grant you the right to:

Copy, modify, or distribute the App or any part of it
Create derivative works based on the Service
Use our trademarks without our express written consent

9.2 Your Rights in Your Data

You retain all rights to the personal data you enter into the Service (workout logs, goals, notes). By using the Service, you grant us a limited license to store, process, and display this data solely for the purpose of providing the Service to you. We do not claim ownership of your personal data.

10. User-Generated Content

If you provide content to the Service (such as custom exercise names, workout names, or notes), you:

Retain ownership of such content
Grant HelAI a non-exclusive, royalty-free license to store and display that content to you within the Service
Represent that you have the right to provide such content and that it does not infringe any third-party rights or violate any law

We do not share or publish your personal content. User data (workout logs, notes) is private by default and visible only to you.

11. Privacy

Your privacy is important to us. Our collection and use of personal data is governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Service, you consent to our data practices as described in the Privacy Policy.

12. Subscriptions and Payments

12.1 Free Tier

The core of the Service — workout tracking, the exercise library, the AI form check, and health-data readings — is available free of charge. Data on the free tier is stored locally on your device.

12.2 HelAI Pro

HelAI Pro is an optional auto-renewing subscription offered on a monthly or yearly basis. It unlocks cloud synchronisation of your training data across devices and other Pro features described in the app. Subscriptions are sold and billed by the Apple App Store or Google Play Store; we use RevenueCat, Inc. as our subscription processor (see our Privacy Policy, Section 7.5). We never receive your payment card details.

12.3 Pricing

Current prices are shown in the app before you confirm a purchase. Prices may differ by country and may change; a price change never affects a period you have already paid for and takes effect from the next renewal, subject to the notice the app stores require.

12.4 Auto-Renewal and Cancellation

A subscription renews automatically at the end of each billing period unless you cancel at least 24 hours before it ends. Cancellation is done in your App Store or Google Play account settings — we cannot cancel a store subscription for you. Deleting the app, or deleting your HelAI account, does not cancel billing. After cancelling you keep Pro access until the end of the period you have paid for.

12.5 Refunds

Refunds are governed by the refund policy of the store that sold you the subscription. Because payment is taken by Apple or Google, we cannot issue refunds directly; we can help you with a store request.

12.6 Right of Withdrawal (EU/UK Consumers)

If you are a consumer in the EU or UK, you normally have 14 days to withdraw from a purchase of digital content. By starting a subscription you ask for immediate access and acknowledge that you lose the right of withdrawal once the content has been supplied, to the extent permitted by law. Your statutory rights and the refund policy of the app store are unaffected.

12.7 Right of Withdrawal (Brazil and Argentina)

Brazil. Article 49 of the Código de Defesa do Consumidor gives you 7 days from the purchase to change your mind about a distance purchase, with no reason and no penalty. This right cannot be waived and applies even though the payment was taken by Apple or Google. Write to [email protected] and we will support your refund request with the store; if the store refuses, contact us and we will settle it directly.

Argentina. Article 34 of Ley 24.240 gives you 10 days to revoke a distance purchase, with no reason and at no cost.

12.8 Changes to Pro Features

We may add, change, or discontinue individual Pro features. If we materially reduce what an active subscription provides, we will notify you and you may cancel as described above.

13. Third-Party Services and Integrations

13.1 Apple Health and Google Health Connect

The Service integrates with Apple Health (iOS) and Google Health Connect (Android) to read health metrics. Your use of these platform services is governed by Apple's and Google's own terms and privacy policies. We are not responsible for the practices of Apple or Google.

13.2 Garmin Connect IQ

If you pair a Garmin smartwatch, your use of the Garmin Connect IQ ecosystem is governed by Garmin's terms and privacy policy. HelAI communicates with your Garmin device over Bluetooth Low Energy only.

13.3 Google Firebase

The Service uses Google Firebase for authentication, data storage, cloud synchronisation, push notifications, remote configuration, analytics, and crash reporting. Your use of the Service involves processing of certain data by Google pursuant to Google's terms and privacy policy. See our Privacy Policy for details.

13.4 RevenueCat

Subscription purchases and entitlements are managed through RevenueCat, Inc. RevenueCat receives the product you purchased, purchase and expiry dates, the store transaction identifier, and your subscription status, identified by your account identifier. See our Privacy Policy for details.

13.5 No Endorsement

We do not endorse and are not responsible for the content or practices of any third-party services referenced in or accessible through the Service.

14. Availability and Modifications

14.1 Service Availability

We make no guarantee that the Service will be available at all times or without interruption. The Service may be unavailable due to:

Scheduled maintenance
Unplanned outages
Force majeure events (natural disasters, internet infrastructure failures, government actions, etc.)

14.2 Modifications

We reserve the right to:

Modify, suspend, or discontinue any feature or portion of the Service at any time
Add new features, which may be subject to additional terms
Change these Terms (see Section 20)

We will provide reasonable advance notice of material changes where practicable.

15. Limitation of Liability

To the fullest extent permitted by applicable law:

15.1 Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, RELIABILITY, OR NON-INFRINGEMENT.

WE DO NOT WARRANT THAT:

THE SERVICE WILL BE ERROR-FREE OR UNINTERRUPTED
ANY DEFECTS WILL BE CORRECTED
THE AI FEEDBACK WILL BE ACCURATE OR APPROPRIATE FOR YOUR SPECIFIC CIRCUMSTANCES
THE SERVICE IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS

15.2 Limitation of Damages

IN NO EVENT SHALL HELAI OR KONSTANTIN YEFTIFEYEV BE LIABLE FOR ANY:

INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES
LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES
PERSONAL INJURY OR PROPERTY DAMAGE ARISING FROM YOUR USE OF THE SERVICE
DAMAGES ARISING FROM UNAUTHORIZED ACCESS TO YOUR ACCOUNT

15.3 Maximum Liability

OUR TOTAL LIABILITY TO YOU FOR ANY CLAIMS ARISING UNDER THESE TERMS SHALL NOT EXCEED THE GREATER OF:

THE AMOUNT YOU PAID TO US IN THE 12 MONTHS PRECEDING THE CLAIM, OR
USD $10 (TEN US DOLLARS)

15.4 Exceptions

Some jurisdictions do not allow the exclusion of certain warranties or limitation of liability for certain types of damages. In such jurisdictions, our liability is limited to the maximum extent permitted by law. Nothing in these Terms excludes liability that cannot be excluded by law (such as death or personal injury caused by our negligence, or fraudulent misrepresentation).

16. Indemnification

You agree to indemnify, defend, and hold harmless HelAI and Konstantin Yeftifeyev from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to:

Your violation of these Terms
Your use of the Service in an unauthorized manner
Your violation of any third party's rights
Any content you submit or provide through the Service

17. Dispute Resolution

17.1 Good-Faith Negotiation

We encourage you to contact us at [email protected] before initiating any formal legal proceedings. We commit to engaging in good-faith efforts to resolve disputes informally within 30 days of receiving notice.

17.2 Arbitration (Where Applicable)

In jurisdictions where arbitration is enforceable and permitted, disputes that cannot be resolved informally may be submitted to binding arbitration in accordance with the applicable arbitration rules. The seat of arbitration will be the Republic of Kazakhstan unless otherwise required by applicable law.

17.3 Consumer Rights

Nothing in these Terms limits your rights as a consumer under the mandatory consumer protection laws of your country. If you are a consumer in a jurisdiction that grants you the right to bring disputes before local courts or regulatory bodies, these Terms do not restrict that right.

17.4 No Class Action

To the extent permitted by law, you agree that disputes will be resolved on an individual basis and that you waive your right to participate in class-action lawsuits or class-wide arbitration. This provision is not applicable where prohibited by law.

18. Governing Law

These Terms are governed by and construed in accordance with the laws of the Republic of Kazakhstan, without regard to its conflict of law principles.

If you are a consumer in the European Union, the United Kingdom, Brazil, Argentina or any other country whose law grants you mandatory consumer protections, those protections apply notwithstanding this choice of law, and any clause in these Terms that conflicts with them does not apply to you.

If you are a consumer in the European Union, you may also bring a complaint to the consumer protection authority or the competent court of the country where you live. (The European Commission's Online Dispute Resolution platform, which earlier versions of these Terms referred to, ceased operating in July 2025.)

19. Severability and Entire Agreement

If any provision of these Terms is found to be invalid, illegal, or unenforceable under applicable law, that provision will be modified to the minimum extent necessary to make it enforceable, or severed from these Terms, and the remaining provisions will continue in full force and effect.

These Terms, together with the Privacy Policy, constitute the entire agreement between you and HelAI with respect to the Service and supersede all prior agreements, communications, or understandings.

20. Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will:

Display a notice in the App on your next launch
Update the "Last Updated" date at the top of this document

Your continued use of the Service after the effective date of updated Terms constitutes your acceptance of the changes. If you do not agree to the updated Terms, you must discontinue use of the Service and delete your account.

We will not apply material changes retroactively to your account without your explicit consent.
