Terms of Service

Last updated: 2026-05-03

By using Factor Weave (the "Service") you agree to these terms. If you don't agree, don't use the Service.

1. The Service

Factor Weave provides quantitative-finance data — daily factor scores, vector similarity search, forward-return labels, and a market-regime indicator — through a REST API and an MCP server. We update the data daily after market close. Latency, completeness, and availability are best-effort.

2. Not investment advice

The Service is informational only and is not investment, legal, tax, or other professional advice. Nothing in the Service constitutes a recommendation to buy, sell, or hold any security. Past performance — including any backtest, label, or "historical analogue" feature — does not guarantee future results. You are solely responsible for any investment decisions you make. We are not a registered investment adviser, broker-dealer, or financial planner.

3. Accounts & access

You're responsible for keeping your password and API keys confidential. Treat fw_live_… keys like passwords. We may suspend or close accounts that abuse the Service, share credentials, or attempt to circumvent rate limits or tier gates.

4. Subscriptions & billing

• FREE tier is permanent and requires no payment. Paid tiers (HOBBY, PRO, QUANT) are billed monthly or annually via Stripe at the price displayed at checkout.
• Subscriptions auto-renew until you cancel. Cancel anytime from the Stripe billing portal — your subscription remains active through the end of the paid period.
• Annual plans: pro-rated refund available within the first 30 days. Monthly plans: no refunds; cancellation takes effect at the next renewal.
• An expired or failed subscription downgrades the account to FREE without notice.
• Prices may change with at least 30 days' notice for existing subscribers.

5. Acceptable use

• Don't redistribute the raw data feed, scrape beyond your daily quota, or resell access without a written agreement.
• Don't use the Service to send spam, conduct fraud, or violate any applicable law (including securities laws).
• Don't reverse-engineer, attempt to bypass authentication, or probe for vulnerabilities outside of a coordinated disclosure.
• Coordinated security disclosure: email support@factorweave.com.

6. Data sources & intellectual property

The data we serve is derived from third-party market-data providers and our own factor computations. We grant you a non-exclusive, non-transferable license to use the data to power your own applications, research, and trading decisions. Output you generate from your own use of the Service is yours.

7. Warranty disclaimer

The Service is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, completeness, non-infringement, or uninterrupted operation. We do not warrant that the Service will be free of errors, bugs, or interruptions, or that any data point is accurate.

8. Limitation of liability

To the maximum extent permitted by law, Factor Weave's total liability for any claim arising out of or relating to the Service is limited to the amount you paid us in the 12 months preceding the claim, or USD $100, whichever is greater. We are not liable for trading losses, lost profits, lost data, or any indirect, incidental, special, consequential, or punitive damages.

9. Termination

You can stop using the Service at any time by deleting your account or letting your subscription lapse. We may terminate or suspend access immediately for violations of these terms, abuse, or non-payment.

10. Changes

We may update these terms from time to time. Material changes will be announced on this page with a revised "Last updated" date and, where reasonable, by email. Continued use after the change constitutes acceptance.
