Except as noted below, Chimap offline map applications for Android phones and devices do not collect ANY data from your device. No connection is made to the Internet in order to avoid roaming charges for you.
If you have problems with your application and it crashes, you will be asked permission to send a crash report. This is information collected by Google Crashlytics system and made available to us, the developer. It contains technical data. It does NOT contain your location nor anything about you personally. We recommend that you say yes, but you do not have to. This will alert us to any problem and hopefully allow us to fix it. We will not use the data for any other purpose nor release the data to any third party.
