I’m evaluating an iOS app that uses Family Controls / DeviceActivity for an adult user’s voluntary personal device-management and digital-wellbeing goals. The app would also have an optional social competition feature where friends participate in fantasy-style leagues based on completion of their individual digital-wellbeing goals. I’m trying to understand the restrictions in Apple Developer Program License Agreement Section 3.3.3(P), specifically whether a privacy-preserving result derived locally from Family Controls / DeviceActivity can leave the device when the underlying usage data never does. I’m considering three architectures: A — Locally derived fantasy score DeviceActivity information is evaluated entirely on-device and converted locally into an abstract score. The server receives only: fantasy_points = 82 No Screen Time duration, app identity, website activity, bundle identifier, or underlying usage information leaves the device. B — Binary goal completion A user creates a private usage goal, such as remaining below their chosen daily device-usage threshold. The goal is evaluated entirely on-device. The server receives only: goal_completed = true The server then awards predetermined fantasy points. It never receives the underlying Screen Time value. C — Opaque challenge completion A user privately selects an app/activity goal. DeviceActivity evaluates the threshold locally. The server receives only: challenge_id = C928 completed = true The server knows C928 is worth a predetermined number of points, but does not receive the selected app identity, usage duration, Screen Time quantity, or other underlying DeviceActivity information. In all three approaches, raw Screen Time duration, per-app usage duration, application/bundle identity, website activity, DeviceActivity reports, and underlying historical usage records would remain on-device. Friends would only see fantasy points, matchup results, standings, and/or achievements. My question: Under Section 3.3.3(P) and the Family Controls requirements, are any of A, B, or C permitted? More specifically, does Apple consider an abstract score, boolean goal-completion result, or opaque challenge-completion result to itself be “device or usage data” when it was derived from Family Controls / DeviceActivity? If none of these architectures are permitted, is there a supported privacy-preserving architecture that allows an on-device DeviceActivity evaluation to affect a server-side social or multiplayer feature without transmitting the underlying device/usage information? I’m trying to establish the compliant architecture before development rather than build around an incorrect interpretation of the Family Controls requirements.
