Terms of Use

Effective date: 2026-10-20

These Terms of Use (“Terms”) set out the conditions for using the app “Ongo” (called “つづくログ” in Japanese; the “App”) provided by Ongo Operator (“we” or “us”). By using the App, you agree to these Terms. If you do not agree, please do not use the App.

1. About the App

  • The App is a tool for you to log and look back on habits you choose for yourself.
  • Streaks, completion rates, statistics, and every other number shown in the App are simply summaries of the records you entered.
  • The App does not provide medical, health, fitness, diet, drinking, sleep, or any other advice, diagnosis, or treatment. Which habits you keep, and how much, is your own decision and responsibility. If you have concerns about your health, please consult a doctor or other professional.
  • Reminders are scheduled on your device. Depending on your OS settings and device state, they may not arrive as scheduled.

2. Your records

  • Your records are stored on your device and are not sent to our servers. We do not have your records and cannot view or restore them.
  • If your records are lost because your device is lost, broken, or reset, the App is deleted, or the OS, iCloud, or any other backup fails, we cannot restore them and are not responsible for that loss.
  • You may be able to restore records from an iCloud backup or an exported file, but we do not guarantee it.

3. Sharing

  • The App can turn a streak into a card image that you can share. You decide whether and where to share, and you are responsible for what you share and its consequences.
  • Your use of the services you share to (such as social networks) is governed by their own terms.

4. Paid features (Ongo Pro)

  • Some features of the App are offered as a paid upgrade, “Ongo Pro” (“Pro”). What Pro includes and its price are shown on the purchase screen in the App. Unlimited habits, logging, undo, fixing past days, rest days, and exports are available without Pro.
  • Purchases, payments, and refunds are handled by Apple or Google (the “Store”) under its terms and policies. We do not issue refunds. Please request refunds from the Store.
  • Subscriptions (monthly and yearly) renew automatically for the same period and price unless canceled at least 24 hours before the end of the current period. You can cancel at any time in your Store account settings. Deleting the App does not cancel a subscription.
  • A one-time purchase is paid once and does not renew.
  • You can use Pro again with “Restore purchases” while signed in to the same Store account.
  • If Pro ends, the habits and records you created stay. Using a Pro setting for the first time, or changing one, requires Pro.

5. Prohibited conduct

When using the App, you must not:

  • Violate any law or public order and morals
  • Modify or reverse-engineer the App, or use paid features by unauthorized means
  • Interfere with the operation of the App, or infringe the rights of us or any third party

6. Changes, interruption, and discontinuation

We may change the App, suspend it temporarily, or stop providing it, without prior notice. Except as provided in Section 8, we are not liable for any damage this causes you. If we stop offering a subscription, we will announce it in advance in the App or on this website.

7. Disclaimer of warranties

The App is provided “as is” and “as available”. To the maximum extent permitted by law, we make no warranties of any kind, express or implied, including warranties of accuracy, completeness, usefulness, fitness for a particular purpose, freedom from bugs or errors, uninterrupted availability, or compatibility with your device or OS.

8. Limitation of liability

  • To the maximum extent permitted by law, we are not liable for any damage arising from your use of, or inability to use, the App, including loss of records, reminders that did not arrive, damage from decisions made with reference to the App, damage related to content you share, and disputes with third parties.
  • We are not liable for damage caused by the Store, RevenueCat, iCloud, the services you share to, or any other third-party service, except where we are at fault.
  • The two paragraphs above do not apply to damage caused by our intentional misconduct or gross negligence, or where such exclusion is not permitted by applicable law (including consumer protection laws). Even in such cases, except for our intentional misconduct or gross negligence, our liability is limited to ordinary and direct damage, up to the greater of the total amount you paid for Pro in the 12 months before the damage occurred or 3,000 Japanese yen.

9. Your responsibility

If we suffer damage because you violated these Terms or misused the App, you will compensate us for that damage.

10. Changes to these Terms

We may change these Terms when necessary. We will announce the changes and their effective date in advance on this page or in the App. If you use the App after the effective date, you are deemed to have agreed to the revised Terms.

11. Severability

If any provision of these Terms is held invalid under applicable law, the remaining provisions remain in effect, and the invalid provision remains effective to the extent permitted by law.

12. Governing law and jurisdiction

These Terms are governed by the laws of Japan. The district court having jurisdiction over our location has exclusive jurisdiction in the first instance over any dispute relating to the App. Nothing in these Terms limits any rights you have as a consumer under the mandatory laws of the country where you live.
