Subprocessors

A subprocessor is a third-party company that Algebro hires to help run the platform. When you use Algebro, some of your data is processed by these companies on our behalf. For example, our database is hosted by Supabase, and the AI guide is powered by OpenAI.

We publish this list so that schools, districts, parents, and teachers can see exactly who handles student data, what they do with it, and how to verify their security and privacy practices. This is part of our commitment to transparency and to supporting district vendor vetting under FERPA, COPPA, and Florida student data privacy requirements.

Algebro maintains a Data Processing Agreement (DPA) with each subprocessor: executed directly with Supabase and OpenAI (July 2026), and incorporated into the service terms of Clerk, Vercel, Stripe, and Resend. Each subprocessor is contractually required to process data only as needed to provide its service to Algebro and to maintain appropriate security controls.

Before adding a new subprocessor or materially changing the role of an existing one, Algebro will provide advance notice by:

• Updating this page with the new subprocessor and the “Last updated” date
• Notifying customers who have signed a data privacy agreement requiring such notice, on the timeline set in that agreement
• Notifying customers who have opted in to subprocessor change emails (see below)

If a customer reasonably objects to a new subprocessor on data protection grounds, we'll work with the customer in good faith to resolve the concern. If we cannot reach a resolution, the customer may terminate their subscription and receive a pro-rated refund of any prepaid fees.
