Content rights — images, fonts, music, and trademarks are licensed

Using unlicensed content — a commercially-licensed font TTF file distributed without a mobile app license, a stock photo with a watermark removed, background music without a synchronization license — violates copyright law (17 U.S.C. §501) and supply chain integrity (CWE-1357). App stores reject apps containing clearly infringing assets when detected during review, and rights holders can file DMCA takedowns post-publication that force removal within 24 hours. Commercial font licenses for desktop typically explicitly exclude app distribution; Proxima Nova, Gotham, and Helvetica Neue each require separate mobile licensing agreements costing hundreds to thousands of dollars annually.

Audit every asset in assets/, src/assets/, and lib/assets/ before submission. Create a THIRD_PARTY_LICENSES.md at the repo root documenting each third-party asset:

# Find all font files in the project
find . -name '*.ttf' -o -name '*.otf' | sort
# Find all audio files
find . -name '*.mp3' -o -name '*.wav' -o -name '*.m4a' | sort

Replace commercial fonts with open-licensed equivalents: Google Fonts packages (@expo-google-fonts/*) use the Open Font License and are safe for app distribution. Replace stock photos with CC0-licensed images from Unsplash or Pexels (verify each image's specific license for commercial use). For icon libraries, use FontAwesome Free (SIL OFL + MIT) or Material Icons (Apache 2.0) rather than Pro icon sets without documented licenses.
