Google Tightens Android Privacy Rules and Blocks Billions of Malicious Ads

Google has announced a major set of Play policy updates aimed at strengthening user privacy and reducing fraud across the Android ecosystem.

At the same time, the company revealed the scale of its security efforts:

🚨 8.3 billion ads blocked or removed
🚫 24.9 million accounts suspended in 2025

What’s changing in Android privacy?

Google is introducing more granular and user-controlled permissions in Android 17, focusing on two key areas:

  • Contacts access
  • Location data

Smarter contact access (Goodbye full access)

A new Contact Picker will replace broad access permissions.

Before:

  • Apps used READ_CONTACTS
  • Access to the entire contact list

Now:

  • Users select specific contacts only
  • Apps can request only required fields (e.g., phone or email)

👉 This significantly reduces unnecessary data exposure

Better control over location data

Google is also introducing a new location access model:

  • One-time access to a precise location
  • Clear user choice on when data is shared
  • Persistent indicator when apps access location

👉 Users gain full visibility and control

New rules for developers

To comply with the new policies, developers must:

  • Minimize permission usage
  • Justify access to sensitive data
  • Submit Play Developer Declarations for:
    • Full contact access
    • Persistent location tracking

📅 Key timeline:

  • Policy enforcement begins in 2026
  • Pre-review checks start October 27, 2026

Secure app ownership transfers

Google is also tackling fraud in app ownership:

👉 Introducing native account transfer in Play Console

Why it matters:

  • Prevents account hijacking
  • Blocks unsafe practices like:
    • Credential sharing
    • Buying/selling developer accounts
