Article 6 — Meta Advertising Measurement

The Company uses the Meta SDK provided by Meta Platforms, Inc. in order to measure app installations and use attributable to the Company's advertising and to improve advertising performance. Through this SDK, app events such as app installation, app launch, opening news or video content, and completing a news search, together with app information, device information, and the IP address used for the network connection, may be sent to Meta.

On iOS, WallWall requests permission through Apple's App Tracking Transparency system before enabling advertiser tracking and the collection of the device advertising identifier. If you decline, every feature of the Service remains available to you, and in that case only limited app events and aggregated installation attribution that do not use the advertising identifier may be processed.

The Company does not send your account identifier, email address, search terms, followed sectors or watchlist contents, or the titles of the articles you read to Meta.

• Recipient: Meta Platforms, Inc.
• Purpose: advertising attribution, campaign measurement, fraud prevention, and ad delivery optimization
• Information transferred: app events such as installation and launch; app information; device information; network information including the IP address; the advertiser-tracking choice applied from the iOS App Tracking Transparency decision; and the device advertising identifier where available under the operating system's privacy settings
• Timing and method: transmitted over an encrypted connection when the app is launched or a configured event occurs
• Processing location: the United States and other countries in which Meta processes data
• Retention and use period: for the period necessary for the purposes above, subject to Meta's Business Tools terms and privacy policy

On iOS you can review or change tracking permission in Settings > Privacy & Security > Tracking. On Android you can delete your advertising ID or limit personalized advertising in your device's ad settings. Declining or later withdrawing tracking permission does not restrict your use of the Service.

Article 6 governs the details of what is transferred to Meta Platforms, Inc., why, and the choices available to you.
