VPN and network extension compliance — platform APIs only, no tunnel data collection
Why it matters
Apple guideline 5.4 and Google Play's VPN Service policy require that VPN apps use platform NetworkExtension/VpnService APIs exclusively, with no private API usage — and prohibit collecting user network traffic payloads for any purpose. A VPN that logs DNS queries or packet data to an analytics server violates GDPR Article 5 (data minimization) and CWE-311 (Missing Encryption of Sensitive Data) simultaneously. The business risk is heightened: Apple requires advance entitlement approval for Network Extension, so an app submitted without that approval will be rejected before reviewers even open it.
Severity rationale
Low because VPN apps in compliance are straightforward to approve, and the required entitlements are obtainable through the standard developer portal — the severity reflects that violations are uncommon when the developer is following platform documentation.
Remediation
Verify that all VPN functionality is implemented exclusively via NEVPNManager or NETunnelProviderManager (iOS) or VpnService (Android). Check ios/[AppName]/[AppName].entitlements for the required key:
<!-- ios/MyApp/MyApp.entitlements -->
<key>com.apple.developer.networking.vpn.api</key>
<array>
<string>allow-vpn</string>
</array>
Remove any code that reads or transmits packet payload data — connection metadata (byte counts, duration, timestamps) is permitted; packet.data contents are not. Apply for the Network Extensions entitlement through the Apple Developer portal before submission. Update the privacy policy to explicitly describe what network data the VPN collects and does not collect — reviewers check this.
