Terms of Service

1. Service provider

These services are provided by Alpheth (Hong Kong SAR), referred to below as "we". Registration details are governed by the Business Registration Certificate; this page does not disclose a registration number or registered address.

If you accept these terms on behalf of a company or other organisation, you confirm that you are authorised to do so.

2. The services

QuantSmith is a backtesting and research tool for MetaTrader 5, covering strategy modelling, backtest execution, parameter optimisation and report export. AIChatFlow is a knowledge-base-driven AI customer service workflow tool that connects to official channels and replies automatically.

QuantSmith output is technical research only. It is not investment advice, an offer, or a trading recommendation of any kind. Historical backtest results do not indicate future performance and no return is guaranteed.

We may adjust, improve or retire features. Material changes will be announced in advance through site notices or email.

3. Accounts and eligibility

You may register yourself according to the instructions on the product pages. You must provide information that is true, accurate and contactable, and keep it up to date.

An account may only be used by the registering entity. You are responsible for safeguarding your sign-in credentials and for activity under your account. If you become aware of unauthorised access, notify us immediately.

Each AIChatFlow sign-in account may belong to only one tenant. Subscription ownership and billing permissions are those shown in the account centre.

4. Acceptable Use Policy (AUP)

The following rules are incorporated into these terms and are binding on your use of the services.

• No spam, bulk harassment, unsolicited marketing, or unlawful, infringing, fraudulent or hateful content;
• No circumventing or attempting to circumvent quotas, rate limits, authentication or other technical controls;
• No resale, redistribution, rental or white-labelling of the services, and no providing equivalent hosted services to third parties on our behalf;
• No reverse engineering, scraping, scanning, stress testing or otherwise interfering with the services or networks;
• No uploading malicious code or content that infringes third-party intellectual property or breaches confidentiality obligations;
• No use of the services for money laundering, terrorist financing, sanctions evasion or other unlawful activity.

5. Subscriptions, billing and auto-renewal

Paid tiers are processed through Stripe and similar payment channels on a monthly or annual cycle; AIChatFlow is monthly only. Prices, allowances and currencies are those displayed at checkout.

Subscriptions renew automatically until you cancel. You may cancel in the account centre or the payment provider customer portal. After cancellation you retain the current period until it ends, then fall back to the free tier.

Allowances reset each period: paid tiers follow the subscription anchor day and the free tier follows the calendar month. Annual plans still reset monthly; a full year of allowance is not issued at once. On reaching the limit the service hard-stops until the next period or an upgrade.

If a renewal fails we provide a 7-day grace period during which entitlements remain. If payment is still outstanding when the grace period ends, entitlements fall back to the free tier.

6. Refunds and cancellation

Refunds are governed by the Refund Policy. In short: within 7 days of the subscription start and with no more than 20% of the period allowance used, a full refund may be requested. Beyond those conditions, refunds are calculated pro rata for unused days and reviewed manually. Cancelling a subscription does not by itself trigger a refund.

Send refund requests to support@alpheth.com with your account email and order details.

7. Content and intellectual property

Knowledge bases, prompts, conversations and strategy descriptions you upload remain yours. You grant us a limited licence to process them as necessary to provide the services.

The software, interfaces, documentation and trademarks of the services belong to us or their respective owners. Except as expressly authorised, you may not copy, modify, distribute or create derivative works.

You must ensure that uploaded content does not infringe third-party rights, and you are responsible for content you upload.

8. Data processing roles and subprocessors

For AIChatFlow customer conversation data, you (the tenant) are the data controller and we are the processor. We process data only on your instructions and as described in the Privacy Policy. A Data Processing Addendum (DPA) is available in Simplified Chinese, Traditional Chinese (Hong Kong) and English on request at support@alpheth.com.

We use subprocessors in the following categories: payment processing, email delivery, cloud hosting and identity services. We do not name specific vendors here; details are available from the support email.

Data is stored in the Hong Kong Special Administrative Region of China. Where cross-border transfer applies, we follow applicable law and the Privacy Policy.

9. Disclaimers and limitation of liability

The services are provided on an "as is" and "as available" basis. We make no service level agreement (SLA) commitment and do not warrant uninterrupted or error-free operation or fitness for a particular purpose.

To the maximum extent permitted by law, we are not liable for indirect loss, loss of profit, loss of data or trading losses. For any subscription, our aggregate liability is capped at the fees you actually paid for that subscription in the preceding 12 months.

Nothing in these terms excludes or limits liability that cannot be excluded or limited by law.

10. Availability and changes

We perform planned maintenance and give reasonable advance notice; emergency maintenance may occur without notice.

We may suspend or restrict the services for compliance, security or operational reasons, explaining the reason where reasonable.

11. Termination and data deletion

You may delete your account in the account centre at any time. Once deletion completes, product data is deleted; billing, transaction and tax records are retained for the statutory period of 7 years in de-identified form.

If you materially breach these terms or the AUP, we may suspend or terminate the services after notice. Termination does not affect accrued payment obligations or records that must be retained by law.

12. Governing law and disputes

These terms are governed by the laws of the Hong Kong Special Administrative Region. Disputes arising from these terms should first be discussed in good faith; if unresolved, they are subject to the courts of the Hong Kong Special Administrative Region.

13. Changes and contact

We may update these terms. Material changes will be notified in advance through site notices or email; continued use constitutes acceptance of the updated terms.
