Coralog

Terms of Use

Effective date: June 21, 2026 · Last updated: June 21, 2026

1. Acceptance

By downloading or using Coralog ("the app"), you agree to these Terms of Use. If you do not agree, do not use the app.

2. Not professional advice

Coralog is a personal record-keeping and visualization tool for your own reef-tank husbandry. It does not test your water or verify your readings, and the dosing calculator gives an estimated amount based on the numbers you enter — always check your additive's own label and dose gradually. Coralog does not provide water-quality, chemistry, or veterinary advice and is not a substitute for professional care. For livestock health or serious tank issues, consult an experienced reef keeper or a qualified professional.

3. Your content and data

Your entries are stored only on your device (see the Privacy Policy). You are responsible for your device, for backups you choose to make, and for any files you export and share.

4. License

We grant you a personal, non-transferable, non-exclusive license to use the app for your personal, non-commercial use, subject to these Terms and the Apple Media Services Terms.

5. Subscriptions (auto-renewable)

Coralog offers optional auto-renewable subscriptions ("Coralog Premium") that unlock premium features such as correlation insights, the dosing calculator, parameter-drift alerts, and history export.

Free trial: New subscribers may receive a 7-day free trial. If you do not cancel at least 24 hours before the trial ends, it automatically converts to a paid subscription.
Billing: Payment is charged to your Apple Account at confirmation of purchase. Subscriptions automatically renew at the then-current price unless cancelled at least 24 hours before the end of the current period.
Pricing (may vary by region): Monthly and Annual plans as shown in the app and on the App Store. The Annual plan is offered at a discount versus monthly.
Manage / cancel: Manage or cancel anytime in your Apple Account settings (Settings → your name → Subscriptions). Deleting the app does not cancel a subscription.
Refunds: Handled by Apple per the Apple Media Services Terms; we cannot issue refunds directly.

6. Acceptable use

Do not misuse the app, attempt to reverse engineer it except as permitted by law, or use it for any unlawful purpose.

7. No warranty

The app is provided "as is" without warranties of any kind, to the maximum extent permitted by law. We do not warrant that the app is error-free or that any figure, pattern, or guidance shown is accurate or complete.

8. Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages, or for any decision made in reliance on the app.

9. Governing law

These Terms are governed by the laws of Japan, without regard to conflict-of-laws rules.

10. Changes

We may update these Terms; material changes will be posted here with a new "Last updated" date.
