The majority of the Software's functions operate offline on the user's local system.

The Software itself does not collect, store, or transmit any personal data directly. However, certain features, such as AI narration (text-to-speech), translation, Google transcription and SRT generation from plain text, rely on third-party services like Google Speech Recognition, Google Translate and Google Text-to-Speech (gTTS), which may involve transmitting data (e.g., text for translation or speech generation) to those services.

When using these online features:

1. Data is transmitted directly from the user's device to the third-party service providers without passing through Subtitle Sphere's servers.
2. Users maintain full control over when and what data is transmitted to these third-party services.
3. Users are responsible for ensuring their use of these third-party services complies with the respective terms of service and data policies.

Subtitle Sphere is currently offered as a free software for both personal and professional use. However, we reserve the right to modify our licensing terms, including the potential introduction of paid features or commercial licensing requirements, in the future. Any such changes will be communicated to users and will not affect the core offline functionality of the software.
