Section 01
About subprocessors
These are Kartios’s current direct infrastructure, delivery, and payment providers. Providers may process information on Kartios’s behalf and, for some payment activities, under their own legal responsibilities. Each may use its own subprocessors under its published contractual and privacy terms.
This list should be read with the Privacy Policy and our Security & Privacy page.

Section 03
Services Kartios does not currently use
Customer relationship management platforms, advertising networks, artificial intelligence providers, and a product-email SDK are not current Kartios subprocessors. Workspaces may still begin through a walkthrough, while eligible new workspaces use Stripe-hosted signup when self-service billing is enabled.
Resend currently delivers Supabase authentication emails through SMTP. Kartios does not currently use Resend’s application SDK for product messages.
Section 04
Changes to this list
Kartios will keep this page current. After public launch, we will provide approximately 30 days’ advance notice of a materially new subprocessor when reasonably practicable. A provider needed for an urgent security, legal, or service-continuity reason may be engaged sooner, with notice as practical.
Questions or reasonable objections about a new provider may be sent to jdtozier@gmail.com. Kartios will review them in good faith, but cannot guarantee that every requested alternative provider will be technically or commercially available.
