Are They Hiding an Affair or … Is It Just a Secret Anniversary Gift?
Our phones are most often loyal secret keepers nowadays. Personal moments and relationships stand behind these pervasive devices.
With the suspicion that your partner is hiding something on their phone come feelings of uncertainty and emotional fallouts.
I have been unfortunate enough to have to go through this scenario in my last relationship as well! If you’re here to do some digging, I’ve got you! I understand how important this is to you!
And we’re not just talking hiding secret anniversary gifts. That can be a possibility, right! However, other times the intentions are more malicious than that.
Do you have lots of questions but no answers about their dang phone surrounded by this secretive aura? Mystery is cool, but maybe don’t mix it with cheating and emotional intimacy.
Let’s dive into 9 signs you should look out for to figure if they’re hiding something on their phone. Take these with a pinch of salt and remember that open communication is the second-best alternative to just following your instinct.

1. Guarded and protective body language when using their phone
When your partner likely has something incriminating on their phone, they will exhibit signs of guarded and protective body language.
Subtle cues can be shielding their phone screen from your view, nervous energy when checking their phone around you, and vigilant glances if you’re physically close to their phone.
Sure, I’ve experienced cases when shielding the phone screen is more about privacy and habit and less about hiding and secrecy.
Nonetheless, this number 1 sign will still prompt awful questions like, ‘Am I being paranoid?’ or ‘Is this just in my head?’
I urge you to first notice multiple, if not most, signs before you reach a conclusion as close to reality as possible.
- Do they turn away when writing a text?
- Do they generally keep their phone face down when not using it?
- Do they subtly become cautious and / or nervous when leaving their phone unattended, especially if you’re around?
2. Their phone is (too) securely locked
Have you guys perhaps shared passwords in the past? See how this behavior has changed over time. Are they more reluctant all of a sudden? Have they set up a new method of locking their phone or changed old passwords?
Sharing some innocent passwords can be a great sign of trust, transparency, and commitment in relationships. If this relationship habit is foreign to you and it has never happened though, I’d say consider adding at least 0.5 points to the are they hiding something score!
The first scenario does set a trusting precedent, but a few doubts still remain.
In both cases, the intrigue is simply why? They must need a good reason to ramp up security.
- Have you tried going through their unattended phone but suddenly found that there’s a new password? It could be that something shifted in your relationship trust. Could it be because they now need more independence and are withdrawing from you? Or would it be for worse purposes?
- Have they recently added an additional method of securing their phone? All that extra security must mean something. As for this specific reflection question, I’d say they’re more likely to hide something in there. One phone protection method is usually more than enough.
3. Social media habits are more secretive
Do consider this sign if they’re an active social media user. But if they’re generally not, number 3 might not be an accurate indicator for everyone.
Keep in mind that we all go a bit MIA on social media sometimes, depending on our mood and busy schedules.
If you must know though, here’s a little tip for you. If you have the chance of checking their phone, go to Settings – Notifications. Any notable social media app that has notifications off or notification previews off?
Privacy settings are common (and necessary!) for all of us, but have theirs been abrupt and heightened lately? Lots of aspects to take into account before anything else, aren’t there?
4. Wiping the slate clean
Similarly, if you ever have the chance to go through their phone, it’s a good idea to check call logs, text chats, and app history.
If the history doesn’t go way back and is mostly or recently emptied, it’s a sign that they’re hiding the tracks.
So, are they working hard to not leave any digital traces behind? Or do they usually prefer to constantly delete chats? Questions, questions.

5. Odd hours and patterns
This is mostly useful if you live with your partner. Maybe their phone habits have changed, and they’re now going on their phone late at night? Odd hours and shifts in phone patterns combined with guarded body language can definitely indicate that something is off!
Don’t mean to sound mainstream here, but clandestine interactions do tend to happen late at night.
6. Emotional closeness signs
Even if your partner is potentially good at hiding something, they can’t be good at hiding their emotions in the relationship forever. Inevitably, signs will appear. You’re on the right track to flag those.
- Does your partner’s mood change before or after using their phone? Do they get agitated or withdrawn?
- Can you see signs of anxiety, guilt, or frustration in your relationship dynamics? Or have you two been going through a rough patch anyway?
One’s digital habits will interact with real-life emotions at some point.
7. Hidden identity on social media
Oh, this one hit close to home! I was stunned to find out that my ex was hiding a secret TikTok account from me two years ago. It’s just like your partner is keeping a part of themselves tucked away from your view.
Keep an eye out for secret social media accounts and apps concealed by secret folders and passwords. If smartly installed, did you know that some of these apps may not even be displayed within the phone list of apps.
Even worse, stay on the lookout for a second phone. While there may be illegitimate reasons other than cheating, hiding something is still hiding.
If you’re like me, all this thinking has motivated you to increase privacy measures. Not so much about revenge (where are my Scorpios at?) but security—I invested in this unbreakable privacy screen protector to feel more comfortable using my credit card info in public and sending risky texts…
8. Inconsistent when confronted
Okay, you’ve confronted your partner regarding their phone. Or maybe you’re still waiting on it.
To go on with my story, I did raise this issue with my ex. What happened was that they willingly handed me their phone.
Either way, pay attention to how they respond. They may give you vague answers or change excuses.
Best case scenario, your supposedly loving partner will want to directly address your concerns instead of deflecting them.
- Do they become evasive, vague, inconsistent, or defensive when confronted?
- Do they deny or use subtle emotional manipulation tactics like gaslighting?
9. Consider childhood trauma and lifestyle
Last but not least, I urge you to also consider their childhood trauma and lifestyle.
- Did they need to hide their phone from abusive parents? It could be hard-wired habit.
- Have you not built the type of emotional trust they need? You can work on it together.
- Do you have knowledge of odd activities and contacts in their life? It might not be cheating.
You can work towards a solution – but only together
Open communication, questions, and emotions can do wonders when your partner is the right match for you.
Here, remember that finding common ground on their phone issue can actually strengthen your bond. It’s not always as bad as you think.
I encourage you to trust your intuition but also respect boundaries.
