Terms of Use

Last Updated: 10 September 2026

The Service

Tallwise is a height-prediction and growth-tracking app. Predictions are statistical estimates with a stated error range, calculated from public growth references. They are not a diagnosis, not medical advice and not a promise. Talk to a doctor about any concern about growth.

Subscriptions

• Tallwise Plus is offered as a weekly or a yearly auto-renewing subscription, and some yearly plans include a free trial.
• Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your Apple ID settings.
• Any unused portion of a free trial is forfeited when you purchase a subscription.
• Prices are shown in the app before you buy and may differ by country.

Apple's standard licence terms also apply: Licensed Application End User License Agreement.

Acceptable Use

Use the app for yourself or for a child you are responsible for. Do not attempt to reverse-engineer or resell it.

Liability

The app is provided as is. To the extent permitted by law, we are not liable for decisions made on the basis of a prediction.
