Day by Day Terms of Use

Effective date: September 19, 2026

1. Purpose

These terms set out the conditions for using Day by Day (하루씩, the “App”) and the rights and responsibilities of the operator and users.

2. The service

The App provides the following free of charge:

• Counting and showing the days since a start date you choose
• A daily check-in, with your best record and restarts kept
• Creating shareable card images, saving them to Photos, and sharing them to other apps
• Home Screen and Lock Screen widgets

3. Health notice

• Challenges about drinking, smoking, eating, exercise, or other health topics are a tool for keeping your own record. They are not medical advice and do not replace treatment.
• If you are dependent on alcohol, nicotine, or other substances, or have health concerns, please talk to a medical professional.

4. Your records

• Records are stored only on your device. The operator does not back them up.
• Records may be lost if you delete the App or lose or reset your device. Restoring from a full iPhone backup restores them as well.

5. Cards you make

• You are responsible for the photos and text you put on cards, and must not use material that infringes anyone else's rights.
• Cards you share are subject to the terms of the apps and services you share them to.

6. Ads

The App is supported by advertising. Google AdMob ads appear on the Settings and Records screens and at some points after sharing a card.

7. Limitation of liability

To the extent permitted by law, the operator of this free App is not responsible for:

• Loss of records caused by losing or resetting a device or deleting the App
• Differences in day counts caused by changing the device's date, time, or time zone
• Disputes arising from cards you share

8. Changes to or ending the service

The operator may change or end the service. Important changes will be announced in the App or on this page.

9. Changes to these terms

If these terms change, the new version will be posted on this page with its effective date.
