We use a small number of third parties to deliver Lemma Analysis. Below are 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 that we have signed with them.

LemonSqueezy handles your payment as our Merchant of Record. It receives your payment and card details — which we never see or store — and your email address. As Merchant of Record, LemonSqueezy is an independent data 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, your holdings, or any other personal data. They are therefore not subprocessors of your personal data.
We update this page when we add, remove or change a provider. For a material change we notify account holders by email and update this page at least 30 days before the change takes effect. Questions go to support@lemma-analysis.com.
