Frequently asked questions

Will my records move to a new device?

If you signed in with Google, Apple or Kakao, or linked an account in the Account tab, sign in the same way on the new device to pick up where you left off. Records from use without signing in can't be restored after you delete the App or change devices.

I'm not getting notifications

Check that notifications for the App are turned on in your device settings. The timer keeps running even with notifications off. On Android, power saving or battery optimization can delay notifications.

How do I earn coins?

Through the daily check-in, focus rewards (on days you focus for 5 minutes or more in one go), streaks and rewarded ads you choose to watch — or buy them in the App, or get them with a Pro payment. Spend them in the Shop on hats, outfits and room themes. Coins from a payment refunded by the store are taken back.

No rewarded ad shows up

Sometimes the ad provider has no ad to show. Please try again a little later. There's also a daily limit.

Delete your account and data

You can delete your Cat's Study account (operated by Lo-Fi Labs Inc.) and all of its data at any time.

Delete in the App

1. Open the Account tab at the bottom.
2. Tap Delete account at the very bottom.
3. Tap Delete account in the confirmation to delete right away.

If a focus session is running, finish it first. If some records haven't been uploaded yet, try again once you're online. Before deleting, you can save your records as a CSV file from the confirmation.

What gets deleted

Your account and sign-in links, settings and resolution, focus records, stats and streaks, tasks and categories, coins and their history, your items and badges, your friends list and crew memberships (if you were a crew owner, the crew passes to another member), and your push token are all deleted from the server immediately and cannot be restored. Copies in server backups are overwritten according to the backup cycle.

If you signed in with Apple, you can also remove the App's connection in iPhone Settings > Apple Account > Sign-In & Security > Sign in with Apple.

Request without the App

If you can't use the App, email support@catsstudy.com. For a signed-in account, include the sign-in method (Google, Apple or Kakao) and that account's email address. After confirming it's you, we'll delete it within 10 days and let you know.

For accounts used without signing in, there's no way to tell whose account it is once the App is deleted, so we may not be able to find it. Please delete your account in the App before deleting the App.
