Google Photos

Photo management · 7の代替ツール

Google Photos aggregates memories with AI sorting, face recognition, and shared albums. Since 2021 the free unlimited tier ended—photos are among your most personal data.

なぜ Google Photos から離れる?

Face labels, places, and people tags can feed cloud AI. Account suspension can lock you out of years of memories. Taking back long-term control is worth the effort.

Googleの限界・リスク

  • Since 2021, unlimited high quality ended—15 GB shared quota applies
  • Face recognition and location tie into Google’s ML pipeline
  • Shared albums and “Memories” lock into your Google account
  • Original-quality long-term storage effectively requires Google One paid plans
