Terms of use

Effective November 9, 2026.
These terms cover the Evenreef iPhone app and the website at evenreef.com, run by Ilyas Kaizar Colombowala ("we" or "us"). By using either one, you agree to them.

Dosing guidance is informational

Evenreef calculates doses from manufacturers' published data and from the test results you enter. The results are information to help you decide what to do; they are not a guarantee. Test kits vary in accuracy, products and their formulas change, and every tank behaves differently. Confirm with a fresh test before a large correction, and follow the product label.
You are responsible for your livestock and for everything you add to your tank, including any dose the app or the AI advisor suggests. The advisor's answers are written by an AI model and can be wrong, even though every dose it suggests is checked against the same limits as the dose check.

Evenreef Plus

Evenreef Plus is an auto-renewing subscription, sold in the iPhone app and billed by Apple to your Apple account when you confirm the purchase. It renews automatically for the same period at the current price unless you cancel at least 24 hours before the current period ends. You can manage or cancel it in iPhone Settings: tap your name, then Subscriptions. If you buy a subscription during a free trial, any unused part of the trial ends. Apple handles refund requests.

Apple's Standard EULA

If you use the iPhone app, Apple's Licensed Application End User License Agreement (the Standard EULA) also applies.

Fair use

Do not interfere with the service, try to get around its usage limits, or use it to break the law.

Evenreef is provided "as is" and "as available", without warranties of any kind, including fitness for a particular purpose, to the fullest extent the law allows.

Limitation of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special or consequential damages, including the loss of fish, corals, other livestock or equipment, arising from your use of Evenreef. Our total liability for any claim is limited to the greater of what you paid for Evenreef Plus in the 12 months before the claim or US$50.
