Sub-processors
Last updated 20 July 2026
To run Mainframe101 we use a small number of trusted providers who process personal data on our behalf. This page lists them and what they do.
These providers act as our sub-processors under our privacy policy. Each is bound to process personal data only on our instructions and to keep it secure.
| Provider | What they do for us |
|---|---|
| Supabase | Database and authentication — stores account, waitlist, and learning data. |
| Resend | Email — sends messages to the address you give us, and stores our email contact and mailing list. |
| Vercel | Hosting and privacy-friendly analytics — serves the site and product. |
Changes
As the product grows we may add or change providers. When we do, we will update this page and the date above. If you are an organisation or education customer and would like to be notified of changes to this list, let us know.
