There is no personally identifiable data collected, but some usage data and minimal device-related data may be collected for the purpose of improving the app. By default, this information is periodically sent automatically, but you can disable yourself by going to the Profile screen, turn on Special Optionz, and then under the Telemetry section, disable Auto Report Errorz and Auto Report Activity.
Unless you feel strongly, we recommend leaving these on so we can improve the app for everyone. Don't be selfish...
To request your data be deleted, please email pebblezpuzzlez@outlook.com. We will advise you of next steps (since we'll need some information to do so).
