Effective October 8, 2026
This is a previous version. See the current version
These Terms set the conditions for using the app Cat's Study (the “App”) provided by Lo-Fi Labs Inc. (“we”). By using the App, you agree to them.
1. The service
The App offers a focus timer, records and stats, task planning, room and cat decoration, background sounds and a friends and crews feature for free, and needs an internet connection. The App has no boards, posts, comments, chat, messages or photo uploads. We may change or pause features when needed and will announce important changes in advance.
2. Accounts
Starting without signing in creates an anonymous account; if you delete the App or change devices, its records can't be recovered. To keep them, link a Google, Apple or Kakao account. Don't use anyone else's account.
3. Coins and items
Coins are earned only through daily check-ins, a 5-minute focus once a day, streaks and rewarded ads you choose to watch, and cannot be bought. Coins and items are licenses for use inside the App with no cash value; they can't be exchanged for money, refunded or transferred. How they're earned is shown in the App and may change. We may take back coins or items obtained improperly, and all of them are lost when you delete your account.
4. Ads
The App shows banner ads and rewarded ads. You watch rewarded ads only when you want to; rewards are granted when you watch to the end and it's recorded, with a daily limit. Advertisers are responsible for their ads.
5. Friends and crews
The friends and crews feature is available to users aged 14 or older who have linked an account. You become friends when you send a request by ID and the other person accepts. A crew is a small group you join with an invite code or a friend's invite (up to 3 crews per person, 12 people per crew). Others see only the fixed information in section 2 of the Privacy Policy and pats; there is no chat or free-form messaging. The crew owner who created a crew can rename it, remove members (removed people can't rejoin) or delete the crew.
- Names, IDs and crew names may not contain contact details (phone numbers, messenger IDs, email, etc.), links or promotion, impersonation of other people or companies, or insults, hate or sexual content.
- You can report a name or crew name. If 3 different users report it within 30 days, the name is hidden automatically, and if it's a person, their friend requests, crew creation and invites are paused. After reviewing, we may unhide the name, change it or restrict use.
- Searching, requests, invites and pats have limits to prevent spamming.
- You can remove or block a friend at any time, and leave a crew at any time.
6. Prohibited conduct
- Getting records or coins by modifying the App, automation, or manipulating the device clock or server requests
- Fraudulent ad views or taps, attacking the servers, or reverse engineering or copying the App
- Harassing others, spamming or promoting through the friends and crews feature
- Copying or distributing the App's artwork, text or sounds without permission, or otherwise breaking the law
If you break these rules, we may take back coins or items, change your name, restrict your use of the friends and crews feature, or delete your account. You can object by email.
7. Deleting your account
You can delete your account any time with [Delete account] at the bottom of the Account tab; your account, records, coins and items are deleted immediately and can't be restored. If you can't use the App, ask us by email.
8. Rights
Rights to the App's artwork, characters, text, sounds and software belong to us or their rightful owners. Tasks, resolutions, names, crew names and other text you write belong to you, and we use them only to provide the service and to operate these Terms.
9. Limitation of liability
The service is provided free and as is. We aren't liable for causes beyond our control, such as disasters, network failures or device settings (notifications off, power saving, clock changes), or for records lost by deleting the App on an anonymous account. This doesn't apply to damage caused by our intent or gross negligence.
10. Changes and governing law
When we change these Terms, we'll announce it in the app or on this page with the effective date; if you disagree, you can delete your account. We'll give 30 days' notice before ending the service. These Terms are governed by the laws of the Republic of Korea, and disputes go to the competent court under the Korean Civil Procedure Act. Consumers abroad keep the rights given by the mandatory laws of their country.
Addendum: these Terms take effect on October 8, 2026.
