Most people configure a video calling app once, during the rush of installing it, and never look at the settings again. That initial setup is designed to get you into a call quickly rather than to protect you, and the defaults reflect that priority. Whether you use live video chat for work, for family or for both, a handful of settings are worth revisiting, and none of them take long to change.
Camera and Microphone Permissions
The first thing worth auditing is not inside the app at all, but in your operating system. Both iOS and Android, and every desktop platform, maintain a list of which applications have been granted camera and microphone access. That list tends to accumulate over the years, and it is common to find permissions still active for apps you installed once and forgot about.
Revoke anything you do not currently use. A well-behaved app will simply ask again when it next needs access. It is also worth checking whether your system shows an indicator when the camera or microphone is active, since most modern platforms now display one, and knowing what it looks like means you will notice when something is recording unexpectedly.
Who Can Call You in the First Place
Many apps default to allowing calls from anyone who has your number or username, which is rarely what people actually want. Look for a setting that restricts incoming calls to your contacts, or that routes unknown callers to a request rather than ringing your phone directly.
Related to this is contact syncing. Several services ask to upload your address book on first launch in order to find people you know. This is convenient, but it also means the details of everyone in your contacts, including people who have never used the service, have been shared. If you agreed to this at setup, most apps allow you to disconnect and delete the uploaded data afterwards.
What Your Background Is Telling People
Video reveals more than most people consciously register. Post, whiteboards, family photographs, the view from a window, a school uniform hanging on a door: all of it is visible to everyone on the call and to anyone recording it.
Background blur is the simple fix and is now built into most applications, but it is often disabled by default. Turning it on permanently is more reliable than remembering to enable it for individual calls. It is also worth checking the camera preview before joining, which most apps offer and most people skip.
Meeting Links and Who Can Join
Anyone who has a meeting link can generally use it, and links get forwarded. If your app supports waiting rooms, passcodes or restricting entry to invited addresses, these are worth enabling for anything that is not deliberately public.
Pay attention to whether links are reusable as well. A personal meeting room with a fixed address is convenient, but it means every person you have ever sent that link to retains a permanent route into your calls. Generating a fresh link for each meeting avoids the problem entirely.
Recordings, Transcripts and What Happens Afterwards
The final setting to review concerns what persists after the call ends. Many services now record, transcribe or summarise by default, and store the results in the cloud where they may be accessible to other people in your organisation or retained under a policy you have never read.
Check whether recording is on automatically, where the files are stored, how long they are kept and who can retrieve them. If the service offers automated transcription or AI summaries, check whether that content is used for training. These options are usually available but rarely prominent.
In conclusion, protecting your privacy on video calls is less about avoiding the technology than about spending twenty minutes adjusting defaults that were chosen for convenience rather than for you. Audit your system permissions, control who can reach you, manage what your camera reveals, treat meeting links as the credentials they are, and know what is being kept afterwards. Do it once and the settings will look after themselves.
