Terms of Service

Last updated: 2026-05-14

Welcome to readbiz (ReadBiz, the "Site", "we", "us"). Please read these terms before using anything here. By visiting the Site, creating an account, or paying for a subscription, you agree to everything below. If you don't agree, please don't use the Site.

1. What we provide

The Site takes public XBRL financial data from the U.S. Securities and Exchange Commission's EDGAR system (10-K, 10-Q, 20-F filings, etc.), normalizes it, translates it into Chinese, and displays it alongside plain-language explanations and automated health checks.

This includes cross-company unified statement headers across the income statement, balance sheet and cash flow statement; quarter-over-quarter trends; year-over-year deltas; click-to-explain tooltips; sign-aware labelling for bidirectional line items; written business narratives; and any features we add over time.

2. Not investment advice

This is the most important clause. Everything on the Site — data displays, explanations, health checks, trend charts, business narratives, everything — is for informational and educational purposes only. None of it is investment advice, an offer, a solicitation, a recommendation, or any kind of guarantee.

• We don't sell securities, don't act as an investment adviser, and don't make buy/sell decisions for you.
• We don't predict prices and don't guarantee any returns.
• Every investment decision is yours. You bear your own gains and losses.
• If you're unsure whether something fits your situation, please consult a licensed professional.

3. Data sources & accuracy

All raw financial numbers come from the SEC EDGAR public API. What we do is normalization and translation — we do not modify the underlying numbers. We are, however, not liable for:

• Errors, delays, or omissions in the SEC's underlying data.
• Errors we may introduce in XBRL tag mapping, field aggregation, or unit conversion.
• Judgment errors in our explanations, health checks, or business narratives.

You can — and should — verify any number against the original 10-K or 10-Q. Spotted something wrong? Email support@readbiz.app.

4. Accounts

Some features require an account (email login or Google OAuth, with identity provided by Supabase). Once you register:

• You're responsible for safeguarding your credentials and for everything that happens under your account.
• Please use a real email so we can reach you about account, subscription, or security matters.
• If you believe your account has been compromised, email us immediately.

You can request deletion of your account and associated data at any time by email.

5. Waitlist & email

Joining the Waitlist means you agree to receive email notifications from us when the companies you requested go live. Every email contains an unsubscribe link; once you unsubscribe we delete your email. See our Privacy Notice for details.

6. Paid subscriptions

Some features are offered through paid subscription tiers (such as "Founding"). Subscription terms:

• Pricing: the price shown on the Site's checkout page at the time of purchase governs. Founding (early-bird) pricing is available only for a limited number of seats or a limited window; once that closes, standard pricing applies.
• Billing: subscriptions auto-renew monthly (or on whichever cycle you choose) via Stripe until you cancel. Stripe is an independent third-party payment processor; the payment step is also governed by Stripe's own terms.
• Cancellation: you can cancel any time from your account page. After cancellation you keep access through the end of the period you've already paid for; we don't bill you again.
• Refunds: except where applicable law requires otherwise, paid subscription fees are non-refundable. If you believe there was a material malfunction or an erroneous charge, email us and we'll review case by case.
• Price changes: we may change prices for future billing periods. We'll notify you by email before the change takes effect; you can cancel before the next renewal if you don't want to continue.
• Taxes: unless otherwise stated, listed prices may not include applicable taxes, which Stripe may collect on our behalf based on your jurisdiction.

7. What you can and can't do

You're welcome to:

• Browse, search, and read content on the Site normally.
• Cite our pages in blog posts, research articles, and on social media with a link and proper attribution (see the citation note on our About page).
• Tell your friends interested in U.S. equities about the Site.
• Let AI assistants reference our pages as described in llms.txt.

You may not:

• Scrape the Site at scale (please use the SEC EDGAR public API directly — it's more reliable).
• Repackage, resell, or redistribute our normalized and translated dataset, or pass it off as your own product.
• Reverse-engineer the Site, run load or penetration tests against it, or send malicious traffic.
• Circumvent paywalls, share a paid account with many other people, or commit payment fraud.
• Use the Site for illegal activity, fraud, or to mislead other people's investment decisions.

If you violate any of the above, we may restrict access, suspend, or terminate your account without notice, and we reserve all legal remedies.

8. Intellectual property

Raw SEC EDGAR data is in the public domain. We hold copyright and other applicable rights in our original content — including but not limited to our tag-mapping logic, terminology translations, written explanations, business narratives, health-check rules, design, and code. Except for the citation uses explicitly allowed in section 7, you may not copy, modify, redistribute, or use our content commercially without written permission.

9. Third-party services

The Site relies on the following third-party services; your use of those features is also subject to each provider's terms:

• SEC EDGAR — source of financial data.
• Supabase — account identity and Waitlist data storage.
• Stripe — payment processing for paid subscriptions.
• Cloudflare — site hosting, email routing, and Turnstile bot protection.
• Google — Google OAuth sign-in (if you use it).

10. Service availability

We do our best to keep the Site up, but we don't guarantee 24/7 uninterrupted access. Maintenance, upgrades, third-party outages, and SEC API issues can all cause temporary unavailability. We also reserve the right to add, change, or retire any feature at any time.

11. Limitation of liability

To the maximum extent permitted by applicable law:

• The Site is provided "as is" without any express or implied warranty of merchantability, fitness for a particular purpose, or non-infringement.
• We are not liable for any indirect, incidental, special, punitive, or consequential damages arising from your use of (or inability to use) the Site, including but not limited to investment losses, lost profits, lost data, or lost opportunity.
• For any direct damages, to the extent permitted by law, our total aggregate liability shall not exceed the subscription fees you actually paid to us in the 12 months preceding the event; if you haven't paid us anything, the cap is USD 20 (or equivalent).

12. Termination

You can stop using the Site any time. We can suspend or terminate your access if you violate these terms. Sections that by their nature should survive termination (such as limitation of liability, intellectual property, and dispute resolution) survive.

13. Changes to these terms

We may update these terms from time to time. For material changes we'll update the "Last updated" date at the top of this page and notify you by email (if you have an account) or via an in-Site notice. Continued use after changes take effect means you accept the new terms.

14. Minors

The Site is not directed at children under 14. If you are under 18, please use the Site only with a guardian's consent and supervision, and do not purchase any paid subscription.

15. Disputes

If something goes wrong, please email support@readbiz.app first — we're a small team and we'd rather resolve things through a direct conversation than anything else. We read every message.

If informal resolution doesn't work, the consumer-protection laws and ordinary legal rules of your own jurisdiction apply. Nothing in these terms is intended to waive any non-waivable consumer right you have where you live.
