Sales Tax & Tip Calculator does its job entirely on your device. We do not have an account system, and we do not collect, store, or sell your personal information. The amounts you type never leave your phone.
Bill amounts, tip percentages, chosen state and preferences are stored only locally on your device and are used only to perform the calculations and remember your settings. They are not transmitted to us.
The free version shows ads via Google AdMob. Google may collect and use data as described in Google's advertising and privacy policies to serve and measure ads. You can remove all ads by upgrading to Pro. See Google's Privacy Policy.
Pro upgrades are processed by the Google Play Store or Apple App Store. We never see or store your payment details; those are handled by the respective store under its own privacy policy.
If you choose to send feedback, the message and basic app context (app version, language, platform) are emailed to us so we can respond. Providing feedback is entirely optional.
The app is a general-audience utility and is not directed at children under 13.
