Questions
Where do the figures come from?
From public sources: company announcements, SEC filings and press reports. Each figure has its date and a link to the source. Valuations are reported figures, not market prices.
How does the trial work?
You enter a card in Stripe Checkout and use the full plan for 14 days. If you cancel before the trial ends, nothing is charged.
Can I change plan or cancel?
Yes, at any time from your dashboard: card, plan, invoices and cancellation are in the billing portal.
Is this investment advice?
No. Unicorn Data provides information only, with no recommendation to buy or sell anything.
Do I get an invoice?
Yes. Stripe issues an invoice for every payment automatically, with your company details and tax ID.
