Will I be charged after my free trial?

No. The free trial never turns into a paid subscription on its own, so you won't be charged unless you choose to subscribe.

The AeroLOPA app is free for 14 days after you first sign in. When the trial ends, the app shows the subscribe screen. Nothing is billed unless you pick a plan there.

Signed up by mistake, or don't want to continue? You don't need to do anything. There's nothing to cancel. You can stop using the app or delete it.

Already subscribed? Then it's a regular subscription, billed by Apple or Google. See How do I cancel Pro or get a refund?.

The aerolopa.com website stays free whatever you decide.
