Terms of Service

August 31, 2026

These Terms set out the conditions for using Cat Log (the “App”). Please read them before using the App.

1. About the App

The App is a notebook for logging what happens in your cat’s litter box and looking back at it. Several cats can be logged separately.

2. It does not diagnose illness

The App is not a medical device and not a diagnostic tool. A “worth a look” flag only tells you that an entry matched a fixed condition; it does not decide whether your cat is ill. If something worries you, consult a veterinarian.

3. Eligibility

The App is intended for users aged 13 and over.

4. Your data

The App keeps your data on your device. Backup and migration are your responsibility. If data is lost through device failure, loss, replacement, or deletion of the App, we cannot restore it.

5. Pricing, renewal, and cancellation

  • Registering cats, logging every day and browsing the history all work without paying. What Pro adds is listed on the “Pro” screen inside the App.
  • Monthly plan: ¥490/month in Japan. A 3-day free trial is configured for the first subscription (whether it applies is decided by Apple).
  • Yearly plan: ¥2,980/year in Japan. It has no free trial.
  • There is no one-time “pay once, keep forever” purchase.
  • Payment is charged to your Apple ID. It renews automatically for the same period unless cancelled at least 24 hours before the period ends.
  • Cancel from Settings on your iPhone → your name → Subscriptions. Deleting the App does not cancel a subscription.
  • Prices vary by country and over time. The amount shown in the App Store before you buy is the price that applies.
  • Refunds follow Apple’s policy. We cannot process refunds ourselves.

6. Usage records are sent

The App sends usage records to our server at launch. The fields and the destination are described in the Privacy Policy. The current version has no setting to stop this. If you do not agree, please do not use the App.

7. Prohibited conduct

Reverse engineering, modifying, or redistributing the App, impersonating others, and using the App for unlawful purposes are prohibited.

8. Limitation of liability

Except in cases of intent or gross negligence on our part, we are not liable for damages arising from use of the App. Entries and flags are a prompt to look. Decisions remain yours, with a veterinarian’s advice where needed.

9. Changes to these Terms

We may revise these Terms when needed. Material changes will be posted on this page. Continuing to use the App after a change means you accept the revised Terms.

10. Governing law

These Terms are governed by Japanese law. The Tokyo District Court has exclusive jurisdiction as the court of first instance for disputes relating to the App.
