It should be assumed that any app that won't allow public review and independent builds of their source code can and will take actions for profit you may not approve of at any time, be it intentionally or out of negligence. Letting a third party run code on your system they don't permit you two or someone you trust to see is a bit like being asked to adopt a legal contract that has some amount of power over you you are not permitted to read. If you want apps willing to prove you can trust them to respect your privacy and freedom, the reasonably strict process of apps in the F-Droid store are what you are likely looking for. There is an accountable and privacy preserving alternative for almost everything.
