Terms of use
Last updated 12 November 2026
These terms apply to Yellowkey: the website, the API and the connector for AI assistants (together, the service). By creating an account or using the service you accept them. If you do not accept them, do not use the service.
1. What Yellowkey is
Yellowkey is a research and information service on listed companies and exchange-traded funds. It organises what companies and fund issuers publish (reports, results calls, fund documents) together with market and financial data, and answers questions about them, in part with the help of AI models.
2. Not investment advice
Yellowkey gives information. It does not give investment, legal, tax or accounting advice, does not recommend buying, selling or holding any security, and does not take your personal situation into account. Nothing in the service is an offer or a solicitation. You alone are responsible for your investment decisions; speak to a qualified adviser before making them.
3. Accuracy
We work to keep the data and the answers accurate and dated, and we show sources where we can. Even so, data can be late, incomplete or wrong, and answers written by AI models can contain errors or omissions. Check anything that matters against the original document before you rely on it. The service is provided as it is.
4. Your account
- You must be at least 18 and able to enter into a contract.
- You sign in with a Google account. Keep access to it secure; you are responsible for what is done with your account.
- One account is for one person. Do not share it.
- API keys are secrets. Keep them on a server, never in a web page or an app, and revoke a key you believe is exposed.
5. Plans, allowances and payment
- The Free plan costs nothing and has a small allowance. Paid plans are billed in advance, each month, through our payment provider, at the price shown when you subscribe. Prices include or exclude tax as shown at checkout.
- Each plan has an allowance: questions, API calls, and calls made through the connector. When it is used up, the service tells you so; the allowance restarts at the next period, or you can change plan or buy extra usage where offered.
- A subscription renews each month until you cancel. You can cancel at any time from your billing page; the plan stays active until the end of the period already paid, and that period is not refunded, unless the law where you live gives you a right to a refund.
- We may change prices or allowances for future periods. We will tell you beforehand, and you can cancel before the change applies.
6. What you may and may not do
You may use the service for your own research, personal or professional, and quote short extracts of answers with a mention of Yellowkey.
You may not:
- copy, extract or download the data or the documents in bulk, or build a database or a competing product from them;
- resell, sublicense or redistribute the data, the documents or your access, or let other people use your account or keys;
- get around allowances, limits or access controls, including by using several accounts;
- probe, overload or disrupt the service, or try to obtain how it is built;
- use the service against the law, or to mislead others about a security.
Outputs obtained through the API or the connector may be used inside your own tools and workflows, within the same limits.
7. Content and rights
The service, its presentation, its data organisation and its texts belong to Yellowkey or to those who license them to us. Company reports, transcripts and fund documents belong to their publishers or licensors; you get access to read them through the service, not the right to republish them. Your questions remain yours; you allow us to process them to provide the service.
8. AI assistants and other tools
When you connect Yellowkey to an AI assistant or call it from your own software, that product is run by someone else under its own terms. We are responsible for the data Yellowkey returns, not for what the other product does with it or writes around it.
9. Availability and changes
We aim for a service that is available and fast, without guaranteeing that it will never be interrupted. We may add, change or withdraw features. If we withdraw a paid feature you rely on, you may cancel and stop paying.
10. Suspension and closure
You can close your account at any time by writing to us. We may suspend or close an account that breaks these terms, puts the service or other users at risk, or is not paid. Where reasonable, we warn first.
11. Liability
To the extent the law allows, Yellowkey is not liable for investment losses, lost profits, or indirect damage arising from the use of the service, and our total liability for any claim is limited to the amount you paid for the service in the twelve months before the claim. Nothing in these terms removes rights that the law gives you as a consumer and that cannot be waived, or liability that cannot be limited by law.
12. Changes to these terms
We may update these terms. The date at the top shows the latest version. For a change that matters, we tell account holders by email or in the service before it applies. Using the service after that date means you accept the new version.
