Everything you type is transformed on your device and is never sent to us or anyone else. The last text you typed is kept on your device so it is there next time. The Home Screen widget stores the text you give it on your device. The share menu action reads only the text you choose to share with it, and keeps nothing.
On iPhone and iPad the app shows ads from Google AdMob. Google may collect your device's advertising identifier, approximate location from your IP address, and information about how ads are shown and tapped, to serve and measure ads. The app asks your permission before using the advertising identifier for tracking; if you decline, you still see ads, just less relevant ones. In the EEA, the UK and Switzerland you are asked for consent first, and you can change your choice any time under Settings, Ad privacy choices. Google's policy: policies.google.com/privacy.
Remove Ads is sold through Apple. We never see your payment details. Once bought, the ad SDK is never started.
We do not run our own servers, create accounts, collect analytics, or sell personal data.
The app is not directed at children under 13.
If this policy changes, the new version appears here and in the app under Settings, Privacy policy.
