Bugfender is only active if you ask it to be. If you discontinue a paid Bugfender subscription service, the free Bugfender SDK will stop sending logs to our servers, but will continue to output log files locally on the device just as if you’d used the native logging facilities of your platform.

There’s no problem in leaving the free Bugfender SDK in your application and continuing to use it for your local log output. It’s also convenient in case you’re experiencing problems and want to sign up for the paid Bugfender subscription service again at a later time.
