Announced: 2026-10-20 · Effective: 2026-11-19 (previous version: 2025-09-29) For Users who sign up after the announcement date these Terms apply from sign-up; for existing Users they apply from the effective date.
These Terms govern your use of the “The Hey Ai” service provided by Hey Ai Co., Ltd. (the “Company”). By installing or using the Service you agree to these Terms.
1. “Service” means the software the Company provides under the name The Hey Ai, together with the servers and web pages connected to it:
– The Hey Ai (mobile app, Android)
– The Hey Ai PC (PC app for Windows)
2. “User” means a person who has agreed to these Terms and uses the Service.
3. “Account” means the identity created with an email address or a social sign-in; the same Account can be used in the mobile app and the PC app.
4. “Paid Service” means a subscription (such as Premium) or a pass (such as a Lifetime Pass or a 1-Year Pass) used for a fee.
5. “Credits” means the monthly allowance of AI usage that each plan provides.
1. You must be at least 14 years old. Users under 14 need the consent of a legal guardian; residents of the EEA and the United Kingdom must be at least 16.
2. The Company may refuse or restrict the use of anyone who has previously violated the law or these Terms.
1. Keep your Account information accurate and do not share your password or sign-in method with anyone.
2. You are responsible for everything done through your Account. Tell the Company at once if you believe your Account has been compromised.
3. One Account may use the PC app on the number of PCs allowed by its plan; the number of PC swaps is as shown on the plan screen.
1. The Company grants you a non-exclusive, non-transferable, revocable license to use the Service for personal, non-commercial purposes.
2. You must not:
– copy, modify, reverse-engineer, extract the source code of, redistribute, resell or rent the Service, its software or its AI models;
– circumvent security measures, make bulk calls with bots or automation, misuse the API, or burden the Service or its servers;
– create or send content that infringes the rights of others (copyright, likeness, personal data and so on) or that violates the law or public morals;
– use the Service to operate another person’s PC, device or account without that person’s consent;
– use the Service for unlawful surveillance, fraud, distribution of malicious code or spam.
3. Do not use the Service while driving or in any situation that needs your attention. The Service does not provide emergency calling or rescue functions.
1. The Service generates responses and actions with artificial intelligence. AI responses may be inaccurate, incomplete or unsuitable for your situation.
2. AI responses are not a substitute for professional advice (medical, legal, tax, financial, safety or otherwise). Consult a professional for important decisions.
3. How you use AI responses and actions is your decision, and you are responsible for the results.
1. The Hey Ai PC carries out operations on your PC in response to your voice or text commands: launching programs, arranging windows, opening files and folders, typing text, adjusting the volume and the like. These operations execute the command you gave, and the changes they make to your PC (moving, deleting or sending files, changing settings, sending messages and so on) are attributed to you.
2. The AI may mishear or misinterpret a command. Check the screen before an action that cannot be undone (deleting, sending, paying). Back up important data in advance.
3. Features such as “See the screen”, “Read notifications” and “Register my voice” work only when you have turned them on, and you can turn them off in Settings at any time. How the information these features handle is processed is described in the Privacy Policy.
4. The PC app works through Windows features and other programs. Some functions may not work for reasons outside the Company’s control, such as changes to the operating system or other programs, blocking by security software, or network failures.
5. The Company is not responsible for problems that arise from using the PC app to access the devices, accounts or services of third parties.
1. Plans, prices, and the features and Credits of each plan are as shown on the plan screen in the Service or in the store. The Company may change prices and plan contents; changed prices do not apply to a period already paid for.
2. Paid Services in the mobile app are billed through Google Play. Billing, renewal, cancellation and refunds follow Google Play’s billing policies, and you can cancel a subscription at any time in your Google Play account settings.
3. Paid Services in the PC app are billed through the payment providers designated by the Company (credit and debit cards, easy-pay services, PayPal and others). A monthly subscription renews and is charged automatically on the same day each month, counted from the day of payment, and continues until cancelled. You can cancel at any time in “My membership” inside the Service; after cancelling you keep access until the end of the period already paid for, and no further renewal takes place.
4. If an automatic charge fails (card limit, expired card and so on), the Company may notify you and retry for a limited period; after that period the Paid Service stops and your Account returns to the free plan.
5. Passes (Lifetime Pass, 1-Year Pass and others) follow the period and conditions stated at the time of purchase and do not renew automatically. Event and promotional benefits may be changed or ended for new users with prior notice; benefits already granted remain as stated.
6. Credits are provided anew each month according to the plan. Unused Credits do not carry over to the next month and are not refunded in cash.
7. Receipts and tax documents are issued through the payment provider or the Company as the law requires.
1. For a Paid Service in the PC app you may withdraw and receive a full refund within 7 days of the day of payment, provided you have not used the paid features or any Credits of that period. As required by the Act on Consumer Protection in Electronic Commerce (Republic of Korea), you are informed before payment that withdrawal may be restricted once the Paid Service has started and paid features or Credits have been used.
2. If you cancel a monthly subscription after using it or after the 7 days, the fee already paid for the current month is not refunded; renewal stops from the next billing date.
3. If a 1-Year Pass is refunded after 7 days, the Company refunds the amount paid less the value of the period used (rounded up to whole months) and a cancellation fee of 10% of the amount paid. A Lifetime Pass is refundable only within 7 days of payment and only if unused.
4. If, for reasons attributable to the Company, you cannot use a Paid Service for 24 consecutive hours or more, you may request a pro-rated refund for that period or an extension of your period of use.
5. Where applicable law (including the Korean Act on Consumer Protection in Electronic Commerce and the Content Industry Promotion Act, or the mandatory consumer law of your country of residence) gives you more favourable rights than this Section, that law prevails.
6. Refunds for mobile-app (Google Play) purchases follow Google Play’s refund policy, as set out in Section 7.2.
7. Send refund requests to theheyai@heyaicoltd.com with your payment details (date, payment method, account email). Refunds are made to the original payment method within 3 business days of confirmation (the payment provider may need a few more days to post it).
1. The Company may add, change or remove features and may suspend all or part of the Service for maintenance, outages, security incidents or abuse.
2. The Company gives advance notice in the Service or by email of important changes or discontinuation. If a Paid Service is discontinued entirely, the fee for the remaining period is refunded.
3. The Company may amend these Terms. Amendments are announced in the Service or on this page at least 7 days before they take effect (30 days for changes unfavourable to Users). If you do not agree, you may stop using the Service and delete your Account; continuing to use the Service after the notice means you accept the amended Terms.
1. The Company may restrict your use or terminate your Account without prior notice if you violate these Terms or the law, infringe the rights of other Users or third parties, or endanger the safety of the Service. Fees already paid are not refunded in that case; if it turns out there was no violation, access is restored and the period of use is extended by the length of the restriction.
2. You may end the agreement at any time by deleting your Account. Deleting the Account permanently removes stored conversations, notes and settings.
1. All rights in the Service and its components (software, design, trademarks, text, the AI models and the structure of their output and so on) belong to the Company or their rightful owners.
2. The content you enter into the Service (voice, text, images, notes and so on) remains yours; the Company processes it only to the extent needed to provide the Service.
3. The Company may use your input to improve the Service and its AI only if you have separately agreed by turning on “Help improve the app” in Settings. You can turn it off at any time; the details are set out in the Privacy Policy.
1. The Service is provided “as is”. The Company does not warrant that the Service will be uninterrupted or error-free or that it is fit for a particular purpose.
2. To the extent permitted by law, the Company is not liable for indirect, incidental, consequential or special damages (including loss of profit, data or business opportunity) arising from the use of or the inability to use the Service.
3. To the extent permitted by law, the Company’s total liability is limited to the amount you paid the Company in the 12 months immediately before the event giving rise to the claim.
4. The Company is not liable for damage caused by events beyond its control, such as natural disasters, war, government action, failures of telecommunications or power, or outages of cloud or AI providers.
5. This Section does not apply to damage caused by the Company’s wilful misconduct or gross negligence, nor to liability that cannot be excluded under applicable law.
The Company processes personal data as described in the Privacy Policy, which forms part of these Terms.
1. These Terms are governed by the laws of the Republic of Korea, and the Seoul Central District Court has jurisdiction in the first instance over disputes relating to the Service, unless the mandatory law of your country of residence provides otherwise.
2. If a dispute arises, please contact theheyai@heyaicoltd.com first. The Company will discuss it in good faith; you may also apply for mediation with the Korea Consumer Agency or the relevant authority in your country.
1. If any part of these Terms is held invalid, the remaining provisions stay in force.
2. The Company’s failure to exercise a right is not a waiver of that right.
3. If the Korean and English versions of these Terms differ, the Korean version prevails for Users in the Republic of Korea.
