Terms of Service
& Privacy Policy
1. Agreement
These terms govern your use of the Lightworks Terminal (the “Service”), operated by Greister Technology (“we”, “us”). By creating an account or using the Service you agree to them. If you do not agree, do not use the Service.
2. Eligibility
You must be at least 18 years old and legally able to enter into a contract in your jurisdiction. The Service is intended for professional and institutional use.
3. Your account and its security
You are responsible for the accuracy of the details you register and for keeping your credentials confidential. Notify us immediately if you believe your account has been compromised. We authenticate accounts through Supabase; we never store your password ourselves, and we cannot recover it for you — a reset link is sent to your registered email address.
4. Acceptable use
You agree not to:
- access the Service by automated means intended to extract data at scale, or circumvent rate limits;
- reverse engineer, decompile or attempt to derive source code, except where the law expressly permits it;
- interfere with the integrity or performance of the Service, or attempt to gain unauthorised access to any account, system or network;
- use the Service to break any applicable law, including market-abuse rules, or to redistribute licensed market data beyond what your data licence permits.
5. Market data and no financial advice
The Service displays market data, model output and probabilistic forecasts. None of it is investment advice, a recommendation, or an offer to buy or sell any instrument. Forecasts are estimates derived from historical data and can be wrong. You are solely responsible for your trading decisions and for any loss you incur.
Market data is supplied by third parties and may be delayed, incomplete or unavailable. We do not warrant its accuracy or timeliness.
6. Availability and changes
We may modify, suspend or discontinue any part of the Service at any time. We aim to give reasonable notice of material changes but are not obliged to. Features described as experimental or in preview may change without notice.
7. Intellectual property
The Service, including its interface, models and documentation, is owned by Greister Technology and protected by intellectual-property law. You receive a limited, non-exclusive, non-transferable right to use the Service for your own trading activity. You may not resell or sublicense it.
8. Suspension and termination
We may suspend or terminate your access if you breach these terms, if required by law, or to protect the Service or other users. You may stop using the Service at any time and request deletion of your account.
9. Disclaimers and limitation of liability
The Service is provided “as is” and “as available”, without warranties of any kind to the extent permitted by law. To the maximum extent permitted by law, we are not liable for indirect, incidental or consequential loss, or for lost profits, lost trading opportunities or loss of data. Where liability cannot be excluded, it is limited to the amount you paid us in the twelve months before the claim.
10. Governing law
These terms are governed by the laws of the jurisdiction in which Greister Technology is established, without regard to conflict-of-law rules. Disputes are subject to the exclusive jurisdiction of its courts.
11. Privacy Policy
What we collect
- Account data — your name and email address, and the time you registered.
- Authentication data — handled by our authentication provider. Passwords are hashed by them; we never see them.
- Session data — a short-lived access token and a refresh token, kept on your device so you stay signed in.
- Operational data — the instrument, timeframe and settings you choose, stored locally in your browser.
How your session is stored
Session tokens are sealed in an encrypted vault on your own device using AES-256-GCM. The encryption key is generated by your browser and marked non-extractable, so it cannot be read out by scripts or copied to another machine. We do not keep a copy of your session on our servers beyond what authentication requires.
Third parties
Authentication is provided by Supabase, which processes your email address and credentials on our behalf. Market data is supplied by third-party data providers. We do not sell personal data.
Retention
Account data is kept while your account is active and for as long as we are legally required afterwards. Local session data stays on your device until you sign out or clear your browser storage.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, and to object to certain processing. To exercise any of these, contact us at the address below.
Cookies
The Service does not use advertising or tracking cookies. It stores local data strictly to keep you signed in and to remember your interface preferences.
