Is an app watching you?

How does Spytrap work?

Spytrap runs a background service on your Android phone that watches the camera and microphone at system level. The moment any app activates a sensor, it records four things:

• Which app reached for the sensor
• What time it happened, to the second
• How long it stayed on
• Whether your screen was locked at that moment

Doesn't Android already show a green dot?

It does — for about a second, and then it's gone. The privacy indicators introduced in Android 12 have no memory. If an app used your microphone at 3am while you were asleep, the dot appeared and vanished and nothing anywhere recorded it. Spytrap keeps the permanent history that Android doesn't.

How do I check which apps used my camera on Android?

Android 12 and later include a limited built-in view. Here's how to find it:

1. Open Settings → Privacy (or Security & privacy)
2. Tap Privacy Dashboard
3. Tap Camera or Microphone to see the last 24 hours

What it won't tell you: how long each access lasted, whether your screen was locked, or anything at all beyond 24 hours. That gap is the reason Spytrap exists.

Is this the same as an antivirus or anti-spyware app?

No. Antivirus apps scan for known malicious code. Spytrap doesn't scan anything — it watches behaviour, and reports which apps reach for your sensors and when. A perfectly legitimate app can still use your microphone more than you'd expect, and no spyware scanner would flag it.

Does Spytrap collect my data?

No. There's no account, no sign-up, no cloud and no ads. Everything stays on your device — Google Play's Data Safety section confirms no data collected and no data shared with third parties. Spytrap detects that a sensor was used; it never sees your photos, video or audio.

How much does Spytrap cost?

A one-time $0.99 on Google Play. No subscription, no in-app purchases — every feature is unlocked when you buy it. There's no server behind the app, so there's nothing to bill you for each month.

Who is Spytrap for?

It's built for everyday Android users who'd rather have evidence than a feeling: anyone who has talked about something out loud and then seen an ad for it, anyone handing a phone to a child, and anyone carrying a work device. You don't need to be technical — the whole app answers one question in a few seconds.

What phones does it work on?

Android 8.0 and later. Detection uses several system-level signals in parallel so it keeps working across manufacturers — though aggressive battery managers on some skins can pause background services, and Spytrap tells you when that has left a gap in your log rather than pretending it didn't happen.
