Article 8 (Family sharing and invitations)

3. A user may cancel an invitation or revoke a family member’s access at any time.
Article 9 (Paid Service and auto-renewing subscriptions)
1. The Pro subscription is offered as a monthly or annual product, and payment is taken through the App Store or Google Play from which the app was downloaded. The operator does not hold users’ payment method details.
2. The subscription price and currency are those displayed in each store, and the amount shown in the store at the time of payment is the final amount.
3. Subscriptions renew automatically. Unless cancelled at least 24 hours before the end of the current period, a subscription renews on the same terms and at the same price, and the renewal charge is taken from the user’s payment method within 24 hours of the end of the current period.
4. The annual product includes a 7-day free trial. Unless cancelled at least 24 hours before the trial ends, it converts automatically into a paid subscription and is charged. A free trial is available once per account or store account, and any unused part of the trial is forfeited when it converts to a paid subscription.
5. How to cancel — iOS: Settings › Apple Account › Subscriptions. Android: Play Store › profile › Payments and subscriptions › Subscriptions. Cancelling at any time is possible, and Pro features remain available until the period already paid for ends.
6. When a subscription is cancelled or expires, ads reappear and Pro-only features become unavailable, but the records the user entered are not deleted.
7. If the operator raises the subscription price, it will give 30 days’ notice before the new price applies, and users may cancel before it takes effect.
Article 10 (Withdrawal of subscription and refunds)
1. Under Article 17 of the Act on Consumer Protection in Electronic Commerce, a user may withdraw their subscription within 7 days of paying for the Paid Service. Withdrawal may be restricted where Article 17(2) of that Act applies, for example where the user has already used the Paid Service within that period.
2. Because payment and refunds are handled entirely by the App Store and Google Play, refund requests must be made directly to the relevant store under its refund policy and procedure. The operator has no power to cancel or refund a payment made through a store.
3. How to request a refund — Apple: select the purchase at reportaproblem.apple.com. Google Play: use play.google.com/store/account/orderhistory or the order history in the Play Store app.
4. If you have applied to the store for a refund, it was refused, and you believe your statutory right of withdrawal has been infringed, contact the support page with your payment receipt and the operator will review the store’s handling and provide the assistance needed.
5. No charge is made if you cancel during the free trial.
Article 11 (Payments by minors)
1. Where a minor under the age of 19 pays for the Paid Service without the consent of their legal representative, the minor or their legal representative may cancel that payment under the Civil Act.
2. Cancellation must be requested through the App Store or Google Play where the payment was made, and the store may require supporting evidence such as proof of the family relationship.
3. Cancellation may be restricted where the minor paid with property their legal representative allowed them to dispose of, or where they used deception to make the operator believe they were an adult.
Article 12 (Rights in data and content)
1. The records a user enters or uploads to the Service belong to that user. The operator processes them only to the extent needed to provide the Service (storage, syncing, backup, calculating statistics, producing predictions and displaying them on screen).
2. The operator does not use users’ records for marketing purposes or sell them to third parties. The processing of personal data is governed by the Privacy Policy.
3. Intellectual property rights in the software, design, trade marks and copy of the Service itself belong to the operator or the rightful owner, and users may not reproduce, distribute or create derivative works from them without the operator’s prior written consent.
4. Users may download their own records at any time using the export feature in the app.
Article 13 (Medical disclaimer)
1. The predictions (Smart Flow), statistics, growth charts and notifications the Service provides are reference information calculated from the records the user entered. They are not a medical diagnosis, treatment, prescription or advice.
2. The Service is not a medical device under the Medical Devices Act and is not intended to diagnose, prevent or treat any disease.
3. Always consult a doctor or other medical professional about your baby’s health, feeding volume, growth and medication. In an emergency do not rely on the Service; contact 119 or a medical institution immediately.
4. Notifications may be delayed or fail to arrive depending on the state of the device, the power-saving policy of the operating system and network conditions, so they must not be relied on as the only means of tracking time-critical events such as medication.
Article 14 (Limitation of liability)
1. The operator is released from liability where it cannot provide the Service because of force majeure, such as a natural disaster, national emergency, loss of communications, or the failure of third-party services including cloud providers and app stores.
2. The operator is not liable for loss caused by the user (loss of a device, careless management of sign-in credentials, inappropriate sharing of invitation codes and the like).
3. The operator does not warrant the accuracy of the records a user enters or that predictions based on them will prove correct.
4. Nothing in this Article excludes liability for loss caused by the operator’s wilful misconduct or gross negligence, or any other liability that applicable law does not permit to be limited.
Article 15 (Termination and account deletion)
1. A user may terminate the service agreement at any time through Settings › Account › Delete account in the app, and can follow the guidance at https://babyflow.studiohwi.kr/account/delete on the web.
2. Deleting an account removes the profile, baby information, activity records and uploaded photos without delay, and they cannot be recovered. Baby records shared by several guardians are retained while at least one guardian remains.
3. Deleting an account does not cancel an active subscription. Subscriptions must be cancelled separately in the App Store or Google Play; if they are not, charges may continue after the account is deleted.
4. The operator may terminate the service agreement after prior notice where a user materially breaches Article 7 or breaches applicable law. In urgent cases notice may be given after termination, and the user may object to it.
Article 16 (Dispute resolution and governing law)
1. The operator runs a contact route on the support page in order to take account of legitimate opinions and complaints from users and to compensate for any harm caused.
2. Disputes between a user and the operator are to be resolved by mutual agreement in the first instance; failing agreement, a user may apply for mediation to the Consumer Dispute Mediation Committee of the Korea Consumer Agency or to the Electronic Commerce Mediation Committee under the Act on Consumer Protection in Electronic Commerce.
3. These Terms and the use of the Service are governed by the laws of the Republic of Korea.
4. Any lawsuit arising from use of the Service is to be brought before the court having jurisdiction under the Civil Procedure Act.
