Intellectual Property

1. Your content

You retain ownership of the materials you send to Hemistich (your notes, documents, images, text, and the words you speak when using voice features - "Your Content"). We do not claim ownership of Your Content.

2. Licence you grant us

To operate the service, you grant Hemistich a limited, non-exclusive, worldwide, royalty-free licence to host, process, and transmit Your Content solely for the purpose of providing the features you request (for example, summarizing a PDF or generating flashcards). This licence ends when the content is deleted, except for backups or where retention is required by law. To provide the features, Your Content is sent to the AI and speech providers listed in our Privacy Policy. We do not use Your Content to train AI models, and we do not keep recordings of your voice.

3. Your responsibilities

• You confirm you have the right to upload Your Content and that doing so does not infringe anyone else's rights.
• Do not upload copyrighted material you are not authorized to use. See our Acceptable Use Policy.

4. AI-generated outputs

Outputs Hemistich generates for you (summaries, explanations, quizzes, flashcards, plans, spoken answers, etc.) may be used freely for your personal, academic, and non-commercial purposes. Note that AI outputs may be similar to content generated for other users, and we make no claim of exclusive ownership over them on your behalf. Always review outputs for accuracy and originality before relying on or submitting them (see our AI Disclaimer).

You may not copy, modify, distribute, reverse-engineer, or create derivative works from them, or use our branding, without our prior written permission.
