WhatsApp & Messenger Nastavení soukromí: 12 Must-Change Options

WhatsApp and Facebook Messenger handle billions of messages daily. But the default settings prioritize convenience over privacy. Your profile photo might be visible to everyone, your "last seen" status could be broadcasting your schedule, and your chat backups might be sitting unencrypted in the cloud.

Take 8 minutes to review these 12 settings and significantly improve your messaging privacy.

Part 1: Contact & Profile Visibility

1. Who Can See Your Profile Photo

WhatsApp: Settings → Privacy → Profile Photo

Option	Recommendation
Everyone	Not recommended
My Contacts	Good default
My Contacts Except...	Best for most people
Nobody	Maximum privacy

2. Last Seen & Online Status

WhatsApp: Settings → Privacy → Last Seen and Online

Set to "My Contacts" or "Nobody." This prevents strangers (and potentially stalkers) from tracking when you're active.

3. About / Status Visibility

Don't put personal information in your "About" field. No phone numbers, email addresses, or location details.

Part 2: Chat Security

4. Two-Step Verification

WhatsApp: Settings → Account → Two-Step Verification

Must enable. This adds a 6-digit PIN that's required when registering your phone number with WhatsApp again. Prevents account hijacking.

5. Chat Backup Encryption

WhatsApp: Settings → Chats → Chat Backup → End-to-End Encrypted Backup

Critical setting. Without this, your chat backups on Google Drive or iCloud are stored unencrypted. Anyone who gains access to your cloud account can read all your messages.

6. Mizející zprávy

WhatsApp: Settings → Privacy → Default Message Timer

Set a default timer (24 hours, 7 days, or 90 days) for all new chats. Messages auto-delete after the timer expires.

7. Notification Preview

Phone Settings: Notifications → WhatsApp → Show Previews

Set to "When Unlocked" or "Never." This prevents message content from appearing on your lock screen.

Part 3: Location & Media

8. Live Location Sdílení

Never leave live location sharing running indefinitely. If you use it, set the shortest duration needed and verify it's stopped afterward.

9. Media Auto-Download

WhatsApp: Settings → Storage and Data → Media Auto-Download

Disable auto-download on mobile data and Wi-Fi. This prevents potentially malicious files from automatically downloading.

10. Photo & Video Visibility

WhatsApp: Settings → Privacy → Profile Photo (set to contacts only)

Also consider: Settings → Chats → Media Visibility → Off to prevent WhatsApp media from appearing in your phone's gallery.

Part 4: Zabezpečení účtu

11. Linked Devices

WhatsApp: Settings → Linked Devices

Regularly check which devices are connected to your WhatsApp. Remove any you don't recognize immediately.

12. Blocked Contacts & Spam Reporting

Actively block and report spam contacts. WhatsApp uses reports to identify and ban malicious accounts.

Sdílení Sensitive Info bezpečně

Even with end-to-end encryption, sensitive information you send via WhatsApp stays in chat history indefinitely (unless you use disappearing messages). Screenshots can capture it. Forwarded messages spread it.

For truly sensitive information like passwords, bank details, or access codes, use LOCK.PUB to create a password-protected, encrypted link with an expiration date. The recipient enters the password to view the info, and it auto-deletes when expired — leaving nothing in the chat history.

Shrnutí

Default messaging settings favor convenience over privacy. These 12 changes take under 10 minutes but dramatically reduce your exposure. When you need to share sensitive information through any messenger, use LOCK.PUB to keep it encrypted and temporary.

Your privacy is worth 8 minutes.
