The way we behave online says a lot about us—and sometimes, it can reveal what’s going wrong in a relationship. From sudden privacy changes to secret social media accounts, more people in Singapore are noticing that red flags don’t always start in real life—they begin digitally.

At Top Private Investigator Singapore, we bring you the latest news and behavioural insights observed in private investigator cases. In this article, we break down 7 common online habits that could signal something more serious beneath the surface.

1. They Suddenly Become Secretive About Their Phone

It used to be no big deal when their phone buzzed. But now?

They take their phone everywhere—even to the toilet
They always keep it face-down
They get jumpy if you come near it

Why it matters: Singapore private investigators report that this is one of the most common first signs in digital infidelity cases. When phone behaviour suddenly shifts, there’s often more than just a new mobile game.

2. Passwords Get Changed—And You’re Not Told

Did you used to share access or at least feel trusted with their devices? If they:

Change their phone or app passwords without telling you
Use fingerprint or face ID when they never did before
Log out of accounts they used to leave open

…it might not just be about privacy. It could be about hiding something—or someone.

3. They’re Always “Online,” But Not Talking to You

You notice their green dot on WhatsApp, Instagram, or Telegram, but your messages go unanswered. Later, they claim they were “busy” or didn’t see your texts.

Private Investigator Singapore Insight: Emotional affairs often start with regular online chatting. That active status may be linked to someone new.

4. They’ve Created New Social Media Accounts

You thought you knew all their platforms, but suddenly:

A new Instagram or TikTok pops up
They’ve got a “burner” account with no followers or only a few friends
They post or follow people you’ve never heard of

Creating new accounts without sharing them can be a way to explore new connections in secret.

5. Their Social Media Activity Has Changed Drastically

Look out for:

A spike in posts showing off looks, lifestyle, or gym progress
Flirty captions or comments
Deleting old couple photos—or not posting about you at all

Red flag behavior: When someone is actively trying to appear “single” online, it may reflect a shift in their real-life intentions.

6. They’re Using Encrypted Apps More Often

WhatsApp used to be enough. Now they’re suddenly on:

Telegram (secret chat mode)
Signal
Snapchat (messages that disappear)

What this could mean: Many Singapore private detectives report that cheaters prefer platforms where messages are auto-deleted or hard to trace.

7. You Find Deleted Messages or Cleared Browsing History

If you accidentally see:

A cleared chat log
Deleted messages
Incognito browser tabs

…it may mean they’re not just hiding random browsing—they’re hiding specific conversations or interactions.

Private Investigator Insight: Deleting digital evidence is a common habit among individuals engaging in online flirtation, emotional cheating, or secret meetups.

What Should You Do If You Notice These Signs?

If one or more of these behaviors ring true, it doesn’t always mean your partner is cheating—but it might mean something is off.

Here’s what you can do:

Have a conversation – Gently raise what you’ve noticed. Stay calm and curious.
Observe the patterns – One habit may not mean much, but several could be a sign.
Trust your gut – If you feel something’s wrong, don’t ignore it.
Get clarity – Some turn to digital tools or professional help to understand what’s really happening.
