WhatsApp is probably the app you open more than any other on your phone. Family groups, class groups, work messages, voice notes from friends — half of our daily life now passes through this one green app. And because it is so familiar, most of us install it, tap "agree," and never open the privacy settings again.
I was the same. For a long time, my profile photo, my "last seen," and my About line were visible to anyone who had my number — including people I had never met. A shopkeeper I once bought a charger from could see my photo. A stranger in a group of 200 people could see that I was last online at 2 in the morning.
Nothing terrible happened to me, Alhamdulillah. But when I finally went through the settings properly, I realised how open my defaults were — and how easy they are to fix. In this guide I will walk you through the WhatsApp privacy settings you should change, one by one, in simple words. Each takes a minute or two.

Why WhatsApp's Default Settings Are Too Open
When you create an account, WhatsApp is designed to be social and easy, not private. So by default almost everything is set to "Everyone": anyone can see your profile photo, see when you were last seen, read your About line, and add you to groups.
"Everyone" means every WhatsApp user who has your number, whether they are saved in your contacts or not. And your number travels to many places in normal life — delivery riders, shopkeepers, classmates, people in big groups. Each of them counts as "everyone."
None of this means WhatsApp is a bad app. The controls to fix all of it are built in — WhatsApp gives you the keys, it just does not turn them for you. That part is our job.
Setting 1: Who Can See Your Photo, Last Seen and About
Start here — this is the most important change. Open WhatsApp, go to Settings, then Privacy. (On Android, Settings is under the three dots at the top; on iPhone it is the gear tab at the bottom. Wording can vary slightly between versions, but the Privacy section is always there.)
Profile Photo
Set this to My Contacts instead of Everyone. Friends and family will still see your photo exactly as before; strangers who somehow have your number will see a blank grey circle instead. Most versions also offer "My Contacts Except…" if you want to hide it from a few selected people.
Last Seen and Online
Your "last seen" shows the exact time you were last on WhatsApp, and "online" shows you are using it right now. Together they quietly share your daily routine — when you sleep, when you wake up, when you are busy — with anyone who opens a chat with you.
Set Last Seen to My Contacts, or Nobody for full peace. One honest note: WhatsApp keeps this fair — if you hide your last seen from everyone, you cannot see other people's either. For the "Online" status, choose "Same as last seen" so both follow the same rule.
About and Groups
Set your About line to My Contacts as well. And while you are on this screen, find Groups and change it from Everyone to My Contacts. This stops random people from adding you to random groups without asking — one of the most annoying things on WhatsApp.
Setting 2: Chat Lock for Private Conversations
Some chats are simply nobody else's business: family matters, a conversation with your teacher, something financial. If someone borrows your phone — a very normal thing in our homes — an unlocked WhatsApp means every chat is one tap away.
Chat Lock fixes this. A locked chat moves into a separate "Locked chats" folder that opens only with your fingerprint, face unlock, or phone passcode, and its notifications stop showing message content. To lock a chat, open the conversation, tap the contact's name at the top, and find the Chat Lock option in their profile. You can even hide the locked folder itself, so it appears only when you type a secret code into the search bar.
Locked chats pair well with disappearing messages, found in the same chat info screen: messages vanish after 24 hours, 7 days, or 90 days, as you choose. The other person can still screenshot, so it is not perfect privacy — but for everyday tidiness it is a sensible option.
Setting 3: Silence Unknown Callers and Block Spam
Spam calls and scam messages have become very common. "Sir, you have won a prize." "Madam, your account will be blocked." A strange number video-calling at midnight. Some version of this has reached almost every phone I know.
In Settings → Privacy, look for Silence Unknown Callers (in some versions it sits under Calls or Advanced). Turn it on. Calls from numbers not saved in your contacts will no longer ring and disturb you — they appear quietly in your calls list, so if it was someone genuine, you can simply call them back. Nothing is blocked forever; the noise is just removed.
For spam messages, use the tools already in the app:
- Block: open the chat, tap the number's name, and choose Block.
- Report: when you block, WhatsApp usually offers to report as well. Say yes for clear scams — reports help WhatsApp remove such accounts.
- Never engage: do not reply, do not click links, and never share any code, PIN, or payment detail, however urgent the message sounds.
That last point matters most. No bank, no company, and not even WhatsApp itself will ever message you asking for a verification code. A message asking for a code is a thief wearing a uniform.
Setting 4: Turn On WhatsApp's Two-Step Verification
WhatsApp has its own two-step verification: a 6-digit PIN you create inside the app. Once it is on, anyone who tries to register your number on a new phone — including a thief who somehow got the SMS code sent to your number — will also be asked for this PIN. Without it, they cannot take over your account.
Go to Settings → Account → Two-step verification and turn it on. Choose a PIN you will remember but others cannot guess — not your birth year, not 123456. Add an email address you actually use, because that is how you reset the PIN if you forget it. WhatsApp will occasionally ask for the PIN when you open the app, just so you do not forget it — that small annoyance is the sound of the lock working.
This is the same idea I explained in my guide to password safety and two-factor authentication: one lock can be picked, but two locks make the thief go somewhere else.
Setting 5: Stop WhatsApp Eating Your Storage
This one is not strictly about privacy, but it belongs in any honest settings guide, because for many of us it is the most felt problem: WhatsApp quietly filling the whole phone. By default, every photo, video, and voice note sent to you downloads automatically — including every forwarded video in every family group.
Go to Settings → Storage and data, and under Media auto-download you will find separate options for mobile data, Wi-Fi, and roaming. My honest recommendation:
- Mobile data: turn everything off, or allow photos only
- Wi-Fi: photos and audio if you like, but keep videos off — videos are the real storage killers
- Roaming: everything off
Media then downloads only when you tap it. On the same screen, Manage storage shows which chats use the most space, biggest files first — deleting a few huge forwarded videos can free surprising amounts of room.
Back Up Your Chats Safely
Privacy settings protect your present; backups protect your past. People usually think about them only on the day they lose their phone.
In Settings → Chats → Chat backup, you can back up to Google Drive (Android) or iCloud (iPhone). Set it to run automatically, daily or weekly, and include videos only if you have plenty of space. Before switching phones, make a fresh backup on the old phone, restore it on the new one, and only then factory-reset the old device. Also look for the end-to-end encrypted backup option there: it locks even the backup copy with a password only you hold — if you use it, write that password down somewhere safe at home.
The Unofficial WhatsApp Apps You Must Avoid
A final warning, because I still see these everywhere: GB WhatsApp, WhatsApp Plus, FM WhatsApp and other modified copies of the app. They promise extra themes and tricks like seeing deleted messages. In exchange, you accept three real dangers:
- Account ban. WhatsApp detects unofficial apps and bans numbers that use them — temporarily at first, permanently if you continue. Losing your number means losing your groups and chat history.
- Privacy risk. Your messages pass through software made by unknown people. The whole point of this article is keeping strangers out of your private life — an unofficial app invites them in.
- Malware risk. These apps come from random websites, not the Play Store or App Store, so nobody has checked what else is inside them.
No theme is worth your account. Use the official app and the settings above, and you get both safety and peace of mind.
Frequently Asked Questions
If I set my last seen to Nobody, can I still see others' last seen?
No. WhatsApp keeps this fair both ways. "My Contacts" is the middle path most people choose: your contacts see yours, you see theirs, strangers see nothing.
Will Silence Unknown Callers block important calls from new numbers?
No — it only silences the ringing. The call still appears in your Calls tab, so if a genuine person (a courier, a new client) called from an unsaved number, you can call them back.
What if I forget my WhatsApp two-step verification PIN?
If you added an email address when setting it up, WhatsApp can send a reset link to that email — which is why adding a real, working email matters. Without one, you may have to wait several days before resetting.
Is it safe to back up WhatsApp chats to Google Drive or iCloud?
Yes — it is the normal, official way to protect your chats, and far better than losing everything with a lost phone. For extra protection, turn on the end-to-end encrypted backup and keep its password written down safely at home.
Final Words
None of these changes will make WhatsApp feel different for the people who matter to you. Your family will still see your photo, your friends will still reach you, your groups will still work. The only thing that changes is the audience of strangers — and they quietly lose access they should never have had.
So do not leave it for another day. Open WhatsApp now and spend five honest minutes in the Privacy settings: photo and last seen to My Contacts, two-step verification on, unknown callers silenced, auto-downloads under control. Five minutes, once — and your most-used app becomes a much more private place.
