One of the top reasons new Android applications are rejected during closed beta and production reviews is a Data Safety Section Mismatch. Google's static analysis engine scans your compiled APK/AAB bundle, detects the third-party SDKs and network calls embedded in your code, and cross-references them against what you declared in the Play Console Data Safety questionnaire.

If your app contains an analytics or ads SDK that collects an Advertising ID (AAID) or IP address, but you marked "My app does not collect user data," your submission will be rejected with an enforcement warning. This guide explains how to properly declare your data collection practices in 2026.

1. The Golden Rules of Google Play Data Safety

To avoid compliance violations, you must understand how Google defines data collection:

Use this reference table to accurately map the data collected by popular mobile frameworks and toolchains:

SDK / Library Data Types Collected Purpose / Declaration
Firebase Analytics / Crashlytics Device IDs, Crash logs, Diagnostics, In-app purchase history App Functionality, Analytics, Crash Reporting
Google AdMob Device or other IDs (Advertising ID), Approximate Location, Interaction data Advertising / Marketing, Fraud Prevention, Personalization
Supabase / Firebase Auth Name, Email Address, User IDs, Authentication tokens App Functionality, Account Management
RevenueCat / Google Play Billing Purchase history, User IDs, Transaction logs App Functionality, Fraud Prevention
OneSignal / Firebase Cloud Messaging (FCM) Push Tokens, Device IDs, Interaction logs App Functionality, Developer Communications

3. Data Encryption in Transit & Account Deletion URL

Google Play now mandates two critical disclosures for all apps that handle user data:

A. Encryption in Transit

All data transmitted between your app and external servers must utilize standard cryptographic protocols (HTTPS / TLS 1.3). If your app makes insecure plain-text HTTP calls (except for local testing), your Data Safety declaration must declare that data is not encrypted in transit, which displays a security warning to store visitors.

B. Mandatory Account and Data Deletion URL

If your application allows users to create an account, Google Play requires:

  1. An in-app mechanism allowing users to delete their account and associated personal data.
  2. A public web URL (e.g., https://yourdomain.com/delete-account) where users can request data deletion without needing to reinstall the app.

Warning on Account Deletion Requirements

Simply providing an email address like "email us to delete your account" is no longer compliant for modern production review. You must provide a dedicated web landing page explaining what data is deleted, what data is retained for legal compliance (such as financial records), and an automated or submission-based deletion form.

4. Syncing Your Data Safety Section with Your Privacy Policy

Google employs automated natural language processing (NLP) to inspect the Privacy Policy link submitted in your store listing. Ensure that:
