iOS 18 ATT 2.0 & Android 15 Privacy Sandbox Adaptation

With Apple's 2026 ATT framework upgrade and Google's Privacy Sandbox on Android rollout, we have re-engineered every consent flow in the matrix. ATT prompts are now shown only once per app lifetime (per Apple's guidance), and our Privacy Sandbox Topics API integration is live for the cohort-based ad-relevance use case. The single-attempt consent flow measurably improves opt-in rates without sacrificing user trust.

Following India's Digital Personal Data Protection Act enforcement, we've added a dedicated data-principal rights workflow for Indian users: consent withdrawal, erasure requests, and grievance officer contact are all available in-app and on the website.

Wardrobe Inventory Planner 2.0 — Outfit Calendar

EU AI Act — Generative Content Disclosures

For any future product surface that incorporates generative AI, we have published the full disclosure framework: explicit "AI-Generated" labels, opt-out for AI-assisted features, and a documented model-training data ledger. No current production app uses generative AI; the framework exists so we ship it correctly when we do.
