Subtitle Edit is an offline, open-source application. It does not collect, store, transmit, or analyze the content of your subtitle files, media files, or any associated metadata — not for analytics, not for model training, and not for any other secondary purpose, now or in the future. All core features, including editing, converting, video playback, and local auto-backup , run entirely on your device. Subtitle Edit aims to give you full control over your files — your data stays yours.
