Access to Pytheas²-Lite is subject to these Terms of Use. You may not access or use Pytheas²-Lite or its browser interface for any commercial purposes whatsoever.  You may use Pytheas²-Lite only for lawful purposes and you may not use it in a way that infringes the rights of anyone else or that restricts or inhibits anyone else’s use:

• Who May Use – Pytheas²-Lite is free for academic, non-commercial research.  An account is for one person, so please don’t share your sign-in. Companies should contact us about Pytheas² through Cassia.
• Your Data – Files you upload are used only to run your jobs; we don’t look at them, share them or use them for anything else. They live in temporary storage for your session and are not kept after it ends. Large uploads pass through cloud storage and are deleted once copied into your session. Results you download are held in cloud storage behind a private link that expires after 6 hours, and are deleted within about a day.
• What We Record – For each job we record your username, which step ran and how long it took. We use this to plan capacity and to fix problems.
• No Warranty – Pytheas²-Lite is provided as is, without warranty of any kind. Check important results before you rely on them; Cassia is not liable for decisions made from them.
• Availability – The service may change, pause or end, and accounts may be closed. Workshop accounts close after the workshop.
• Citation – If Pytheas²-Lite contributes to a publication, please cite D’Ascenzo et al., Nature Communications 2022, 13, 2424-2436.

You understand that we have the sole right to determine in our reasonable discretion whether you are engaging in any unauthorized activity and/or violating any term or conditions of these Terms of Use.
