We use a small number of third parties to deliver Lemma Analysis. Below we list the processors that handle personal data on our behalf, and — separately — the payment provider that acts as an independent controller. This page is referenced by our Privacy Policy.
Each of these providers processes personal data only on our documented instructions, under a data processing agreement we have signed with them.

| LemonSqueezy | Merchant of Record — independent data controller for payments | Your payment/card details (handled entirely by LemonSqueezy — we never see or store card data) and your email. As Merchant of Record, LemonSqueezy is a separate controller with its own privacy policy, not our processor. |
We use Twelve Data and Finnhub to fetch market data about public companies. We send them stock tickers only — never your identity, holdings, or any personal data. They are therefore not subprocessors of your personal data.
We will update this page when we add, remove, or change a subprocessor, and we will notify users of material changes by email and by updating this page at least 30 days in advance of the change taking effect. Questions go to support@lemma-analysis.com.
