Conversation is how apps and websites talk to each other — and what they share about you
In tech, conversation means the back-and-forth exchange of data between your device and a company's servers, or between different apps and services. When you load a webpage, send a message, or use a smart home device, your device is having a conversation with distant computers. Each piece of information sent — your location, what you clicked, what you typed — is part of that conversation.
The reason this matters for privacy is straightforward: every conversation leaves a record. The company on the other end can see what you asked for, when you asked, and often where you were when you asked it. If that conversation isn't encrypted, anyone between you and the company — your internet provider, someone on your WiFi network, or a hacker — can listen in and see what you're saying.
Understanding conversation also helps you spot when apps are talking to each other without your knowledge. A fitness app might have a conversation with a data broker. Your smart speaker might be sending conversations to the manufacturer's servers even when you're not actively using it. Knowing this happens is the first step to deciding whether you're comfortable with it.
Key Takeaways
- A conversation in tech is any exchange of data between your device and a server, or between two apps — it happens constantly in the background.
- Unencrypted conversations can be read by your internet provider, your WiFi network owner, or anyone positioned to intercept the data in transit.
- Apps often have conversations with third parties you never agreed to — data brokers, advertisers, or analytics companies — without telling you.
- HTTPS (the "s" in a website address) encrypts the conversation between you and that website, but does not hide what you're doing from the website itself.
- Checking an app's privacy policy tells you which companies it has conversations with and what data gets shared in those conversations.
How a conversation works: the basic flow
When you open your email, your phone sends a conversation to Gmail's servers that says something like: "Here's my username and password — show me my inbox." Gmail's servers respond with a conversation back: "Here are your emails, sorted by date." Your phone displays them. That whole exchange is one conversation.
Conversations happen in pieces called requests and responses. Your device makes a request ("show me the weather for my zip code"). The server sends a response ("it's 68 degrees and cloudy"). A single action — like refreshing your social media feed — might trigger dozens of conversations happening at the same time, each one asking for different pieces of information.
The timing matters. If you're on an unencrypted WiFi network at a coffee shop, someone with basic tools can watch these conversations happen in real time. They can see which websites you visit, what you search for, and sometimes even what you type into forms. This is why public WiFi is risky for sensitive tasks like banking or checking email.
What gets shared in a conversation, and with whom
The obvious things are what you type: your search queries, your messages, your passwords. But conversations also include metadata — information about the conversation itself. Your device's unique identifier. Your location (if the app has permission). The time you did something. What device you're using. How long you spent on a page. Which links you clicked.
Many apps have conversations with companies you've never heard of. When you open a news app, it might simultaneously have conversations with the news publisher, with an ad network, with a data analytics company, and with a tracking service. Each conversation sends different pieces of information. The ad network learns what articles you read. The analytics company learns how long you stayed. The tracking service builds a profile of your habits across multiple apps.
Your phone's operating system also has conversations with Apple or Google. When you use an iPhone, Apple's servers are part of many of your conversations — they handle your iCloud backup, your location services, your app store purchases. When you use Android, Google plays that role. Neither company can see the content of encrypted conversations (like your encrypted messages), but they can see that a conversation happened, when it happened, and often what service it was with.
Encrypted conversations versus unencrypted ones
An encrypted conversation scrambles the data so thoroughly that only your device and the destination server can read it. If someone intercepts it, they see gibberish. Most websites now use encryption (you can tell by the "https://" at the start of the address and a lock icon in your browser). Most messaging apps like WhatsApp and Signal use encryption by default.
An unencrypted conversation travels in plain text. Anyone between you and the destination can read it. Some older websites still use "http://" instead of "https://" — avoid entering passwords or payment information on these sites. Some public WiFi networks, some email services, and some older apps still send unencrypted conversations.
Encryption protects the conversation from being read in transit, but it does not hide the conversation from the company receiving it. When you search Google for "anxiety medication," that conversation is encrypted so your internet provider cannot see it. But Google can see it, because the conversation is between you and Google. Google knows what you searched for. Encryption only protects you from people in the middle, not from the destination.
How to see which conversations your apps are having
On iPhone, go to Settings, then Privacy. You'll see a list of permissions — Location, Contacts, Photos, Microphone, Camera. Tap each one to see which apps have asked for that permission. An app that has location permission is having conversations that include your location data. This doesn't tell you everything the app shares, but it shows you what sensitive data it's accessing.
On Android, the process is similar: Settings, then Apps, then Permissions. You'll see the same categories. Some Android phones also have a Privacy Dashboard that shows you which apps accessed sensitive data recently and how often.
For a fuller picture, read the app's privacy policy. Look for sections titled "Data We Collect," "How We Use Your Data," or "Third Parties." These sections describe which companies the app has conversations with. A fitness app might say: "We share your workout data with our analytics partner Amplitude and our advertising partner Google." That tells you the app is having conversations with those companies on your behalf.
Conversations between apps and services you use
Many apps are designed to talk to each other. You might connect your Spotify account to your Discord account so your friends can see what you're listening to. That connection is a conversation — Discord is asking Spotify for your listening history, and Spotify is sending it. You authorized it, usually by clicking "Connect with Spotify," but the ongoing conversation happens in the background.
Some conversations happen without explicit permission. If you use the same email address across multiple services, data brokers can connect those services together and build a profile of you. They're having conversations with each service, asking "does this person exist in your system?" and building a map of your digital life.
Smart home devices like Alexa or Google Home are constantly having conversations with their manufacturer's servers. They listen for wake words, send audio clips for processing, and report back what they heard. Even when you're not actively using them, they're having background conversations — checking for updates, syncing settings, or sending usage data.
What you can control about your conversations
You cannot stop conversations entirely — they're how the internet works. But you can reduce what gets shared. Turn off location permission for apps that don't need it. Disable microphone access for apps that don't use voice. Log out of accounts you're not actively using so apps can't access them.
Use a VPN (virtual private network) on public WiFi to encrypt conversations that would otherwise be visible to the network owner. A VPN creates an encrypted tunnel between your device and the VPN company's server, so your internet provider and the WiFi network owner cannot see which websites you visit or what you're doing on them. This does not hide your activity from the VPN company itself, so choose a VPN provider you trust.
Check privacy settings in the apps you use regularly. Most social media apps, email services, and messaging apps have settings that let you limit what data they collect or who they share it with. These settings don't eliminate conversations, but they can reduce what gets sent in them.
Frequently Asked Questions
If I use HTTPS, can my internet provider see what I'm doing?
Your internet provider cannot see the content of your conversations (what you typed, what you searched for), but they can see which websites you visited and when. They can see you went to amazon.com at 3 p.m., but not what you searched for or what you bought. A VPN hides even that information.
Does turning off location permission stop apps from knowing where I am?
It stops the app from accessing your GPS location directly. But apps can still estimate your location from your IP address (which is less precise) or from WiFi networks nearby. If you want to be harder to locate, use a VPN and avoid connecting to WiFi networks that broadcast their names.
What does it mean when an app asks for "camera" or "microphone" permission?
It means the app is asking for permission to have conversations that include video or audio from your device. Granting permission doesn't mean the app is always recording — it means the app can access the camera or microphone when it needs to. But check the privacy policy to see whether the app stores or shares that audio or video.
Can I see all the conversations my phone is having right now?
Not easily. Your phone doesn't show you a real-time list of all background conversations. Some phones have privacy dashboards that show you which apps accessed sensitive data recently, but they don't show you every conversation. Using a network monitoring app (available in app stores) can show you which servers your apps are talking to, though interpreting the results requires technical knowledge.
If I delete an app, do the conversations stop?
Conversations from that app stop, but the data the app already sent to other companies remains with those companies. Deleting an app doesn't delete the profile that data brokers or advertisers have built about you. It only stops new data from being sent going forward.
