Welcome to "Heyday" (the "Service"). These Terms of Service (the "Terms") govern the rights, obligations, and responsibilities between Hills Inc. (the "Company") and you, the user.
By using the Service, you are deemed to have agreed to these Terms. If you do not agree to these Terms, please stop using the Service.
These Terms set forth the rights, obligations, responsibilities, and other necessary matters between the Company and the user in connection with the use of the "Heyday" service provided by the Company.
The terms used in these Terms are defined as follows.
The Company will post these Terms within the Service or on a linked screen to notify users.
The Company may amend these Terms within a scope that does not violate applicable laws. When the Terms are amended, the Company will provide notice within the Service specifying the amended content and the effective date.
The amended Terms take effect from the announced effective date, and if the user continues to use the Service after the effective date of the amended Terms, the user is deemed to have agreed to the amended Terms.
The Service provided by the Company includes the following.
The user may create an account to use the Service. Upon first launch, the Company may automatically create an anonymous account based on a device identifier, and the user may subsequently link such account to an authenticated account via Social Login.
The user may create an account or link to an existing account through the social login methods provided by the Company, such as Apple or Google. When using Social Login, the terms of service and privacy policy of the relevant provider also apply.
The user must keep account information accurate and up to date and is responsible for the security of the account. If unauthorized use of the account is detected, the user must promptly notify the Company.
An anonymous account is tied to the device and may become inaccessible upon app deletion, device change, or reset of the device identifier. To preserve held assets, users are encouraged to link the account via Social Login.
Users must not create, use, or provide multiple accounts, accounts in another person's name, or authentication methods to bypass reward conditions or restrictions or obtain other improper benefits. Normal device changes and account linking, recovery, or migration are not in themselves abuse.
The user may accumulate Points or Gold upon meeting the mission and participation conditions shown in the Service. The accumulation ratios and conditions are subject to the Company's policy, which may change from time to time at the Company's discretion.
The user may exchange accumulated Points or Gold for products provided by the Company. The types, prices, and availability of exchangeable products may differ depending on the user's country and the Company's policy.
Fulfillment of product exchange requests is performed by the Company or a third-party operator designated by the Company, and some products may be delivered manually after operator review.
Available missions and products depend on the service country; changing the display language does not change these conditions. Direct bank withdrawals through Heyday are available only in Korea. Japan offers gift cards. The United States catalog includes rewards delivered by external payment providers such as PayPal and Venmo. Receiving these rewards and any subsequent transfer or cash-out from a provider account are subject to that provider's account requirements, eligibility rules, fees, and terms. The baseline redemption value is 10 Points for JPY 1 in Japan, or 10 Points for USD 0.01 in the United States. Product prices, denominations, availability, fees if any, and use restrictions are shown before an order is placed. The displayed point price for the selected product controls the order.
Rewards may be fulfilled through the relevant issuer or payment provider. Review the product country, validity, redemption instructions, and provider terms before ordering. Fulfillment may take time. Where a code or link is issued, it is available in redemption history. For payment-provider rewards, check the delivery email and the receiving account for payout details. An order whose issuance status is uncertain remains under review. Points are returned when fulfillment failure is confirmed; do not submit duplicate orders while an earlier order is processing.
Points and Gold are promotional in-service balances accumulated without charge. They cannot be transferred or inherited. Direct bank withdrawals through Heyday are offered only in Korea. External payment-provider rewards in the United States catalog are governed by the relevant provider's receipt and cash-out conditions. They may expire upon prior notice in cases set by the Company or after a prolonged period of inactivity.
Expired assets are not recoverable, and the Company does not provide any separate compensation for such expiration. Refunds and cancellations after a product exchange has been completed are governed by the relevant product provider's policy and applicable laws.
If the user obtains or attempts to obtain Points, Gold, or products through fraudulent means, the Company may recover such assets and products and restrict the user's use of the Service.
The Company may display advertisements within the Service in various forms, including banners and interstitial ads, for the operation of the Service.
Advertisement availability and personalization may depend on country, device settings, and privacy choices. Weekly Visits requires consent to personalized ads and, on iPhone, tracking permission. Turning this off stops Weekly Visits. Other missions and access to points already earned remain available.
The Company is not responsible for the legality or accuracy of advertisement content provided by advertisers. Where the user transacts with an advertiser through an advertisement, such transaction is between the user and the advertiser, and the Company bears no responsibility for it.
Only with the user's explicit consent, the Company collects the device's location information to provide location-based auxiliary services such as nearby park recommendations.
The user may withdraw consent to provide location information at any time through device settings; upon such withdrawal, the use of location-based auxiliary services may be limited.
Users must not engage in any abuse that undermines normal Service operation or fair use, falsely represents unfulfilled conditions as fulfilled, or bypasses restrictions to obtain improper benefits. The following are examples of prohibited conduct; conduct meeting the above criteria remains prohibited even if its methods or form differ.
If the user breaches the above obligations, the Company may impose measures such as restricting Service use, suspending or terminating the account, and recovering accumulated assets.
The Company may modify, change, add, or suspend all or part of the Service to improve service quality.
Where there is a material change to the Service, the Company will notify users in advance through in-Service announcements. However, in unavoidable cases such as emergency system maintenance or incident response, the Company may provide notice after the fact.
If the Company changes or suspends all or part of the Service provided free of charge, no separate compensation is provided.
All intellectual property rights to the content included in the Service (texts, graphics, logos, images, mission content, software, etc.) belong to the Company or its rightful owners.
Without the Company's prior written consent, the user may not reproduce, modify, distribute, transmit, disclose, sell, or commercially use any content included in the Service.
The Company protects the user's personal information in accordance with applicable laws, and matters regarding the collection, use, and provision of personal information are governed by a separate Privacy Policy.
The privacy policies of the relevant providers (Apple, Google, etc.) also apply to the processing of information collected through Social Login.
Responsibility for the following matters is limited only to the extent that the Company is not at fault. This Article and the third-party provisions in Article 7 do not exclude liability arising from the Company's intentional or negligent conduct or applicable law.
If the Company or a user intentionally or negligently violates applicable law or these Terms and causes loss to the other party, the party responsible for the violation is liable for that loss under applicable law.
These Terms do not exclude the Company's liability for intentional misconduct or gross negligence or any liability that cannot lawfully be excluded, and do not transfer the Company's liability to users or restrict their remedies without sufficient reason.
These Terms are construed and applied in accordance with the laws of the Republic of Korea, without limiting mandatory consumer rights and protections available under the laws applicable to the user.
If a dispute arises between the Company and the user in connection with the use of the Service, both parties shall consult in good faith to reach an amicable resolution.
If the parties fail to reach an agreement, either party may bring a claim before a court with jurisdiction under applicable law. Nothing in these Terms removes a mandatory right to bring a claim in the user's place of residence.
Entire Agreement: These Terms constitute the entire agreement between the Company and the user regarding the use of the Service and supersede all prior agreements.
No Waiver: The Company's failure to exercise or enforce any provision of these Terms shall not be construed as a waiver of such right.
Severability: If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions shall remain in full force and effect.
