Terms of Service

These Terms of Use govern your access to and use of the Asteria Quant platform (asteriaquant.com), provided by Quant Algorithm Tree System Ltd ("QATS Ltd", "we"), an Israeli private limited company (Company ID 517208377). You keep custody of funds on your exchange and remain responsible for the activation, sizing, and risk of any strategy you run.

Effective: 25 May 2026 Version 2.1 (Asteria) Operator: QATS Ltd · Israel

1. Summary

Asteria Quant is a service of Quant Algorithm Tree System Ltd ("QATS Ltd", "we", "us"), an Israeli private limited company (Company ID 517208377), registered office at Maurizio Vitale 3, Tel Aviv, Israel. Throughout these Terms "Asteria Quant", "Asteria", "the Platform", "we", and "us" refer to QATS Ltd in its capacity as operator of asteriaquant.com. You ("user", "you") remain the principal of every trade you execute through the Platform; the Platform is a tool, not an investment adviser, broker, dealer, or custodian.

Plain-English summary. You bring an exchange account and money. You pick a strategy. We send orders on your behalf using a trade-only key. You can pause or stop at any time. Past simulated results do not guarantee future returns.

2. Account

You must be of legal age in your jurisdiction to enter into a binding contract.
You confirm that using algorithmic trading is permitted in your jurisdiction.
You are responsible for the confidentiality of your credentials. We recommend enabling MFA.
One person, one account. Sharing accounts is not allowed.

3. The service

Asteria provides: a strategy catalog (Aster Prime, Aster Surge, Aster Flow and advanced variants), setup review tools, a live execution runner, dashboards, and operational notifications. The service does not provide individualised investment advice. Strategy descriptions, parameters and historical simulations are informational only.

4. Subscriptions and billing

Setup review is part of the activation process and is not a separate subscription item.
Strategy subscription: a per-strategy monthly fee, recalculated daily within published bounds based on strategy metrics and demand. The price you accept at checkout is locked for that paid month.
Live billing is monthly in advance and is processed by Hero Payments (our payment processor). Failed payments may pause Live execution for the affected strategy. Card data is handled by the processor; QATS Ltd does not store full payment-card numbers.
You can cancel at any time from Settings > Billing. Cancellation stops further charges; you retain access until the end of the paid period.
Subscription payments are non-refundable except where required by applicable law or otherwise stated in our Refund Policy.
You are responsible for any taxes (VAT, sales tax, withholding) applicable in your jurisdiction unless they are explicitly included in the price you pay.

5. Risk disclosure

Crypto trading is high risk. You can lose all of the funds you allocate. Algorithmic strategies do not remove this risk and can amplify losses during gaps, exchange outages, regime changes or model mis-specification. Past performance, including simulated performance, is not indicative of future results.

Markets can move further and faster than any stop level; slippage can be material.
Exchange outages, withdrawals freezes, delistings and connection failures can prevent the runner from acting.
API rate limits, partial fills and adverse latency can degrade execution quality.
Leverage, when offered by the exchange, magnifies both gains and losses.

By activating live execution, you confirm that you have read this section and accept the risks. We require an explicit acknowledgement in the Live Activation Gate before live orders are placed.

6. Exchange API responsibilities

Your API keys must be trade-only. We refuse keys with withdrawal permission enabled.
You are responsible for restricting your key by IP if your exchange supports it.
You authorise Asteria to place, cancel and modify orders consistent with the selected strategy.
You may detach a key at any time. Detach stops new orders within seconds, but open positions remain on your exchange under your control.

7. User obligations

You agree not to:

Use the service for market manipulation, wash trading, money laundering or any unlawful activity.
Reverse-engineer the runner, the order router or the strategy code.
Resell, sublicense or operate Asteria as a managed service for third parties without a written agreement.
Attempt to bypass the Live Activation Gate, MFA, or other security controls.

8. Availability

We target high availability but do not guarantee uninterrupted service. Scheduled maintenance, exchange outages, regulatory events or force majeure may interrupt order placement. During an interruption, your open positions remain on the exchange; we do not have the ability to act outside the runner.

9. Intellectual property

The Asteria Quant brand, application, strategy descriptions, dashboards and runner are owned by us or our licensors. You receive a non-exclusive, non-transferable, revocable licence to use the service while your subscription is active. You retain ownership of your trading data; you grant us a licence to process it for the purposes described in our Privacy Policy.

10. Termination

You may close your account at any time from Settings > Account. We may suspend or terminate access for breach of these terms, for security reasons, or where required by law. On termination, we will retain operational logs as described in the Privacy Policy and erase other personal data within 90 days, subject to mandatory retention.

11. No warranty

The service is provided "as is" and "as available", without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, or that the service or any strategy will be profitable, uninterrupted or error-free, to the maximum extent permitted by law.

12. Limitation of liability

To the maximum extent permitted by law, Asteria, its officers, employees and processors are not liable for: trading losses, slippage, missed orders, exchange outages, taxes, or any indirect, incidental, special, consequential or punitive damages. Our aggregate liability for any direct damages is limited to the fees you paid to Asteria in the 12 months preceding the event giving rise to the claim.

Some jurisdictions do not allow the exclusion of certain warranties or limitations of liability. In those jurisdictions, the above limitations apply only to the maximum extent permitted by law.

Force majeure

QATS Ltd shall not be liable for any delay or failure in performance of any part of the Platform caused by events beyond its reasonable control, including but not limited to: acts of God, war, acts of terror, civil disturbances, governmental regulation, pandemic, embargoes, strikes, labour disputes, supply shortages, hardware or software failures, exchange outages, or the failure of any third-party service or utility (such as internet, hosting, or telecommunications).

13. Governing law & disputes

These Terms and any dispute or claim (including non-contractual disputes) arising out of or relating to these Terms or your use of the Platform are governed by the laws of the State of Israel, without regard to conflict-of-laws principles. Disputes will be resolved in the competent courts of Tel Aviv, Israel, unless a different forum is mandatory under your local consumer law. Nothing in this clause limits any mandatory consumer rights you may have under the law of your country of residence.
