Terms of Use

This is a translation provided for your convenience. The Korean version is the official text. If anything here differs from it, the Korean version governs.

Thank you for using "오늘의 너" (the "app"). These terms set out the conditions for using the app provided by Blucy Lab (the "operator"), and the rights and duties of the operator and its users.

• Effective: 3 November 2026

---

1. Terms used here

2. Posting and changing these terms

1. The operator posts these terms in the app and on the support pages.
2. When the terms change, we announce what changes and when, at least 7 days before it takes effect. Changes that are unfavourable to users are announced at least 30 days before, with a separate notice in the app.
3. If you do not agree to the changed terms, you can delete your account at any time.

3. Signing up

1. You must be 14 or older to sign up.
2. You sign up with an email address and password, and you are responsible for your own account. Do not sign up with someone else's email address or hand your account to someone else.
3. Health information is stored only if you separately consent to it under the privacy policy.

4. What the app provides

Cycle logging and predictions, symptom and mood logging, sharing with a partner, suggested actions shown to the partner (coaching), reports, short messages between the couple, and so on. Specific features may change with app updates.

5. Not medical advice

• Cycle, ovulation and fertile-window predictions are estimates calculated from what you logged.
• The app is not a means of diagnosis, treatment or contraception. Do not rely on its predictions for contraception or pregnancy planning.
• If something feels wrong with your body, talk to a medical professional.

6. Connecting with a partner and sharing

1. A partner connects by entering the invite code created by the tracker.
2. The tracker decides what the partner sees. Each item can be turned on or off, and everything can be hidden "just for today". Intimacy records are off from the start.
3. Either of you can disconnect at any time. From that moment the other person can no longer see your records.
4. A partner can only view the other person's records and cannot edit or delete them.
5. Coaching shown to a partner is a general suggestion and does not stand in for the other person's actual feelings or needs.

7. Price and free period

• Without a subscription, you can keep viewing your existing records and calendar. New entries, predictions, sharing, coaching, reports and messages need a subscription.
• If one person in a couple subscribes, both can use subscription features. If you disconnect, the person who did not pay no longer has access.
• You can delete your account at any time, whether or not you subscribe.
• If prices go up, we give notice in advance following each store's process and obtain your consent where the store requires it.

8. Payment, auto-renewal and cancellation

1. Payment is handled by the Apple App Store or Google Play. The operator never receives card numbers or other payment details.
2. A subscription renews automatically for the same period until cancelled, and renewals are charged to your store account.
3. Cancel in the subscription settings of the store of whoever paid. Deleting the app does not cancel it. (iPhone: Settings → your name → Subscriptions / Android: Play Store → profile → Payments & subscriptions → Subscriptions)
4. After cancelling, you can use subscription features until the end of the period you have already paid for.
5. If you downloaded the app from the App Store, Apple's Standard License Agreement (EULA) also applies alongside these terms.

9. Refunds

1. Because the store handles payment, refunds follow each store's refund policy and process. (Apple: reportaproblem.apple.com / Google Play: order history in the Play Store or the Google Play Help Center)
2. These terms do not limit any right of withdrawal or refund that applicable law gives you, including Korea's Act on the Consumer Protection in Electronic Commerce.
3. If the refund process is difficult, contact us at the address below. We will help as far as we can.

10. Our promise about ads and data

The operator puts no ads in the app, does not sell or hand your records to third parties, and includes no analytics or tracking tools. How personal information is handled is set out in the privacy policy.

11. Your records

1. The records you leave are yours. The operator uses them only to provide the app's features.
2. Messages and "my notes" written for a partner also belong to whoever wrote them, and the recipient can see them.

12. What not to do

• Using someone else's account or handing yours to someone else
• Secretly signing up or connecting on another person's device without their consent
• Harassing or threatening others through the app
• Accessing, analysing or disrupting the app or its servers in abnormal ways
• Anything against the law

If we find any of these, the operator may restrict use after giving notice (or afterwards, in urgent cases).

13. Changes to and ending of the service

1. The operator may change features to improve the app.
2. Before significantly reducing paid features or ending the service, we give 30 days' notice. If the service ends, we will explain how each store's refund process applies to any remaining subscription period.
3. The app may be briefly unavailable for maintenance or because of outages.

14. Ending the agreement

1. You can leave at any time from Settings → Delete account. Your account and every record are deleted immediately and cannot be recovered. The subscription must be cancelled separately in the store (section 8).
2. The operator may end the agreement if a user breaks section 12 or is found to be under 14.

15. Limitation of liability

1. Unless there is intent or gross negligence, the operator is not liable for damage caused by events beyond its control, such as natural disasters or network failures.
2. Unless there is intent or gross negligence, the operator is not liable for decisions users make based on the app's predictions or coaching (section 5).
3. This section applies only to the extent permitted by applicable law.

16. Governing law and disputes

These terms are governed by the laws of the Republic of Korea. If a dispute arises, we will first try in good faith to resolve it, and if litigation is needed, it will be handled by the court with jurisdiction under Korea's Civil Procedure Act.
