Daysake Terms of Use

Version 1.0 (English) · Effective date: 2026-11-03 · Last updated: 2026-11-03

These terms are an agreement between you and Inadle (아이나들, "we" or "us"), which runs Daysake. They explain how you can use Daysake and what each of us is responsible for. Daysake is a private notebook where parents and the family members they invite write down a child's day and keep it in one place.

By creating an account, you agree to these terms and to our Privacy Policy (https://daysake.com/en/privacy/).

1. Who we are

• Operator: inadle (아이나들)
• Address: Seongdong-gu, Seoul, Republic of Korea (full postal address on request at [email protected])
• Service: Daysake (어린날 in Korean)
• Contact: [email protected]

2. Who can use Daysake

• You can create an account if you are 18 or older, or the age of majority where you live if that is higher, and you are either a parent or legal guardian of the child, or a family member a parent or guardian has invited to keep the notebook with them. Our Privacy Policy says the same.
• Children do not have accounts and do not use Daysake.
• You confirm that you have the right to write about the child and about any family members you mention, and you write only what you need.
• You may not add a child's information if you are not their parent or guardian or invited by one, or try to get into another family's notebook.
• If we learn that a person does not have guardian rights, or that guardian rights are disputed, Section 9 explains what we do.

3. What Daysake offers

Daysake currently lets you:

• sign up with email and password, Sign in with Apple, or Google (signing up with Kakao is offered when the app is set to Korean),
• add a child's name or nickname and birth month or birthday,
• write short pages, each kept with the date and your child's age at the time,
• answer a weekly question about your child,
• attach one photo to a page,
• choose who sees a page: your family, or "Just me",
• browse pages by month, edit them, or delete them,
• invite another parent or family member with an invite link or code to write in the same notebook,
• download everything as a PDF or a ZIP file, for free.

Photos. You choose one photo from your photo library for a page. We keep smaller copies and a thumbnail, not the original file, which stays on your phone. We ask for your permission the first time you use this feature. If you delete the page, the photo is deleted too.

Daysake does not offer:

• storage of original photo files,
• camera capture, face recognition, or emotion detection,
• voice recording,
• payments,
• public sharing, likes, comments, followers, or rankings,
• scoring, comparing children, or assessing development, health, personality, or future careers.

4. New features

We may add features later, such as voice notes, AI summaries, long-term storage plans, or paid products. The consent you gave when you signed up does not cover them automatically. Before you use a new feature, we will explain what it does, what information it uses, its conditions and price (if any), and how to stop using it, and ask for your consent where needed. You can choose not to use optional features.

5. Your pages

• You own your pages and photos. You give us permission to store, display, and process them only to run Daysake for you and your family, including showing them to the people you invited and making your downloads.
• We keep your original words. The first version of a page is never overwritten. If you edit a page, we keep the edit separately, and the app and your downloads may show the latest version with its edit date.
• Deleting a page removes it from the notebook at once, and we delete it for good within 30 days. This is different from deleting your account, which is described in Section 6.
• Daysake is not medical or professional advice. It does not diagnose, treat, assess development, or tell you how to teach or raise your child. If you are worried about your child's health or development, talk to a qualified professional.

6. Downloads and account deletion

• Download everything (a PDF, or a ZIP file with photos) is free. The file is made on your phone and handed to your phone's share sheet. We do not make download files on our servers.
• Anyone can delete their account in Settings › Delete my account. If you are the only person in your family notebook, the whole notebook is deleted. If others write in it with you, only you are removed and the pages you wrote stay with them, except your "Just me" pages, which are deleted. Details are in the Privacy Policy.
• You can also ask for deletion without the app at https://daysake.com/en/delete-account/. To make sure the request comes from the account holder, we confirm it with a code sent to the email address on the account.

7. Paid services

Daysake does not take payments today. If we offer paid features in the future, we will tell you the price, billing period, refund and cancellation terms, and the role of the app store or payment provider before you buy. We do not collect card numbers or other payment details directly.

Pages you have already written will never be locked behind payment or deleted because of a price change. Writing, reading and Download everything stay free.

8. What you must not do

• Try to access another family's notebook.
• Add a child's information without guardian rights or an invite from a guardian.
• Enter false information or other people's personal information without a right to do so.
• Try to get around Daysake's security or access rules.
• Use Daysake pages to post about, rank, score, or diagnose children.
• Use Daysake in a way that breaks the law or harms others.

9. Limiting or suspending use, and family disputes

If you try to access another family's notebook, add a child's information without the right to, or try to get around our security, we may pause access to Daysake or to the related pages while we look into what happened. Where appropriate, we then delete the account or pages.

If the adults in a notebook disagree about it, for example after a separation or divorce, we do not take sides. We follow a court order or other legal requirement that applies to us. Before we limit access to a notebook or delete pages because of such a dispute, we will tell the people writing in it and give them 30 days to download everything, unless a court order or the law requires us to act sooner.

10. Changes and shutting down

• If features, these terms, or the Privacy Policy change, we will tell you in the app or by another reasonable means. If a change is significant, we will tell you before it takes effect.
• If we ever shut down Daysake or change how long we keep notebooks, we will tell you at least 30 days before, explain how to download or delete your notebook, and keep Download everything working during that time.

11. Our responsibility

We work hard to keep Daysake running and your notebook safe. Please download everything from time to time.

To the extent the law allows, Daysake is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not promise that Daysake will always be available or error-free.

To the extent the law allows, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for losses that we could not reasonably foresee or that were not caused by our failure to meet these terms. To the extent the law allows, our total liability to you for any claim about Daysake is limited to the greater of the amount you paid us for Daysake in the 12 months before the claim or US$50.

Nothing in these terms limits our responsibility for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited by law, and nothing in this section limits rights you have under the mandatory consumer laws of your country (Section 12).

12. Consumer rights, governing law, and disputes

If you are a consumer, nothing in these terms limits rights you have under the mandatory consumer laws of the country where you live, and you can bring a claim in the courts of that country.

In the UK and the EU, you keep the protections of your local consumer law.

If you have a problem, please contact us first at [email protected] so we can try to solve it together.

Apart from those mandatory rights, these terms are governed by the laws of the Republic of Korea, and disputes will be handled by the court with jurisdiction under the Korean Civil Procedure Act and other applicable law. Unless you and we agree otherwise, the Seoul Central District Court will be the court of first instance.
