TipJar is licensed, not sold, to you for use under Apple's standard Licensed Application End User License Agreement (apple.com/legal/internet-services/itunes/dev/stdeula), supplemented by the terms below.
TipJar is a calculator. Every tax-related figure it shows is an estimate based on published IRS and state data. It is not tax, legal, or financial advice, and it does not file returns or report anything to any authority. You are responsible for your own tax decisions. Consult a licensed tax professional before filing.
TipJar offers auto-renewing subscriptions (Pro and Plus, monthly or annual). Payment is charged to your Apple ID. A subscription renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel in your Apple ID settings. Free-trial time is forfeited if you upgrade during a trial.
The app is provided "as is." Estimates may differ from your actual tax liability or paycheck. We are not liable for decisions made based on the app's output.
Use TipJar lawfully. Do not attempt to reverse engineer, resell, or misuse the app.
