Alternative To WhatsApp: Signal
If you use Messenger or WhatsApp and would prefer to do your messaging using an app not owned by Facebook, you should seriously consider switching to Signal. Signal secure messaging is one of the only apps that has its privacy-preserving technology always enabled; this default system ensures that there is never a risk of sharing moments or sending messages to a non-intended recipient. Signal is a cross-platform encrypted messaging service dedicated to end-to-end encrypted voice calling and encrypted texting.
Signal is an Open Source project supported by donations and grants, so there are no advertisements, no affiliate marketers, and no secret tracking. Signal doesn’t have the keys to decrypt messages, so the company will never have access to content its users are exchanging.

Alternative To Google Chrome/Search: Duck Duck Go
Search engines are quite useful but one major demerit of using Google and Bing is that your search term is often shared with third-party sites you visit. Apart from traceable searches, they also intrude your privacy by placing cookies on your device to monitor your search habits. They also deliberately save your search history which can be changed from the setting.

APKPure verifies the legitimacy of all apps before publishing by using SHA1 to ensure the certificate is safe. Cryptographic signatures for new versions of apps must match previously published versions, and entirely new apps are matched against other software from the same developer.

Alternative To Gmail: Criptext
Criptext is a free encrypted email service for Windows, Linux, macOS, Android and iOS. It is not cloud-based like Gmail or Outlook; Criptext emails are not stored on servers permanently, they are only stored on your device using end-to-end encryption. It uses the Signal Protocol for this.
Criptext says that every email is encrypted with a unique key. Attachments are encrypted as well; they are stored on Criptext's Amazon Web Services servers though the encryption keys for those are saved on user devices. The important thing to note here is that the service only encrypts mails sent by one Criptext user to another. So, if you use it to send mails to other services (Gmail, Outlook, etc), those will not be encrypted.
