Terms of Service

Effective September 20, 2026 · GSDAQ app and gsdaq.com · Operated by Gwangsu Kim (“GSDAQ”, “we”), Los Angeles, California, USA · [email protected]

These Terms govern your use of the GSDAQ app and website, including paid subscriptions, AI top-ups, and any legacy credits on your account. The app itself is licensed to you under Apple's standard Licensed Application End User License Agreement; where these Terms and that agreement overlap, that agreement controls the app license and these Terms control the service. By using GSDAQ you agree to these Terms and to our Privacy Policy.

1. What GSDAQ is — and is not

GSDAQ provides information and education about the U.S. stock market: explanations of rules, indicators, news and the views of well-known investors, generated with the help of artificial intelligence. GSDAQ is not a broker-dealer, investment adviser, or financial planner, and nothing in the app is investment, tax, or legal advice or a recommendation to buy or sell any security. GSDAQ does not execute trades, hold funds or securities, or connect to brokerage accounts. You are solely responsible for your investment decisions. Markets involve risk, including the loss of principal; past performance does not predict future results.

2. Eligibility and accounts

You must be at least 13 years old to use GSDAQ, and at least 18 (or the age of majority where you live) to buy a subscription or AI top-up. A paid plan requires a GSDAQ account. Keep your sign-in credentials secure and tell us if you suspect unauthorized use. You may delete your account in Settings → Account. Deletion is permanent, immediately cancels an active subscription, ends access without a prorated refund except where required by law, and forfeits any AI top-up or legacy credit balance.

Where supported, you may connect another sign-in provider to the same GSDAQ account. Linking requires successful provider authentication and verification that the identity belongs to the existing account. Providers or addresses that cannot be verified remain separate. Available login methods may depend on provider configuration.

3. AI-generated content

Answers are produced by third-party language models selected by us for the Free, Quick, and Deep modes, or selected by you when you connect your own supported API key. They can be wrong, incomplete, out of date, or fabricated, including numbers and quotations. Verify anything you rely on. We do not review answers before they reach you. We may change, add, or remove models and providers while preserving the answer allowance of a paid plan.

4. Free use

All feeds, portfolio tools, custom alerts and widgets are free. AI conversations are limited to 5 a day, shared between Quick and Deep. The allowance resets at midnight Pacific Time. Signed-in accounts share this allowance across devices; guests use a device allowance. Reading feeds does not consume a conversation. We may change the limit, models or included features.

5. Billing pause and existing records

  1. Payments paused. New subscriptions, AI top-ups and automatic renewals are paused. A payment is not required for the free features above.
  2. Conversation allowance. Quick and Deep each use one conversation. Only completed answers consume the allowance; failed answers release the reserved conversation. Unused conversations do not roll over. Lesson completion does not add conversations. Service-wide cost limits or provider outages can temporarily interrupt AI access.
  3. Existing balances. Existing credits and payment records are preserved while the account remains open. Credits are not spent on these free conversations and do not extend the daily allowance. They have no cash value. Questions about earlier payments or refunds can be sent to support; this pause does not limit any non-waivable consumer rights.
  4. Account and subscription records. Sign in at app.gsdaq.com and open Settings → Account → Manage subscription when available to view Stripe Billing Portal records. Account deletion remains permanent and removes the account and its credit balance.
  5. Future changes. If paid services return, their price and terms will be shown before purchase. We will provide notice required by law for changes affecting existing rights.

6. Acceptable use

Do not use GSDAQ to: violate any law; attempt to extract, reverse-engineer, scrape, or resell the service, its data feeds, or model outputs at scale; circumvent free-use limits (for example by generating device identifiers); upload content you have no right to share or that contains other people's personal data; or interfere with the service's operation or security. We may rate-limit or suspend abusive use.

7. Your content and our content

You keep ownership of what you upload (questions, screenshots, holdings). You grant us the rights needed to process it to provide the service, including sending it to the AI providers described in the Privacy Policy. Answers generated for you may be used by you freely; we do not claim ownership of them, though similar answers may be generated for others. The app, its design, data compilations, lesson content and branding are ours or our licensors' and are protected by intellectual-property law. Market data and news headlines are provided by third parties under their terms and are for personal use only.

Private investment information. Administrator and customer-support tools do not provide access to your saved portfolio or personal investment details. Support access does not authorize signing in as you or editing your portfolio. Account synchronization and AI processing use the data described in the Privacy Policy.

8. Third-party services

The service depends on Apple, Cloudflare, AI providers (OpenAI, Google, Anthropic), market-data providers and, for web purchases, Stripe. We are not responsible for their availability or their terms, and outages on their side may interrupt the service.

9. Termination

You may stop using GSDAQ at any time, cancel a subscription in the Billing Portal at app.gsdaq.com, or delete your account in the app. We may suspend or terminate access that violates these Terms or creates risk for us or other users. If we discontinue paid service before the end of a paid period, we will provide a prorated refund for the unavailable portion except where the interruption is caused by a violation of these Terms.

10. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ACCURACY, COMPLETENESS, TIMELINESS, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT ANSWERS ARE CORRECT OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, GSDAQ AND ITS OPERATOR WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY TRADING LOSSES, LOST PROFITS, OR LOSS OF DATA, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF US$50 OR THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM. Some jurisdictions do not allow certain limitations; in those places our liability is limited to the extent permitted.

12. Indemnity

You will defend and hold us harmless from claims arising from your violation of these Terms or of any law, or from content you upload.

13. Governing law and disputes

These Terms are governed by the laws of the State of California, without regard to conflict-of-law rules. Before filing a claim, contact us at [email protected] and we will try to resolve it informally within 30 days. Claims not resolved informally must be brought in the state or federal courts located in Los Angeles County, California, or in small-claims court where eligible, and you consent to that venue. Nothing here limits consumer rights that cannot be waived under the law of your residence.

14. Changes to these Terms

We may update these Terms. We will post the new version here with a new effective date and, for material changes, notify you as required by law. If you do not accept a material change, cancel before it takes effect and stop using the service.

15. Apple-specific notice

These Terms are between you and Gwangsu Kim only, not Apple. Apple has no obligation to furnish maintenance or support for the app and is not responsible for addressing any claims relating to it. Apple and its subsidiaries are third-party beneficiaries of these Terms with respect to the app license and may enforce them against you.
