Sub-processors

Mobius Labs Inc., doing business as Matarus (“Matarus,” “we,” or “us”), uses service providers to operate, secure, and support the Matarus services.

Where Matarus processes personal information on behalf of a school, organization, or other customer, these providers may act as sub-processors. Where Matarus determines why and how personal information is processed, they may instead act as processors or service providers to Matarus. This page should be read together with our Privacy Policy and any data processing agreement between Matarus and the applicable customer.

The location summaries above identify primary or typical processing locations and are not exhaustive. A provider may use affiliates or downstream sub-processors in additional jurisdictions in accordance with its agreement with Matarus. Where required, Matarus uses contractual or other safeguards for international transfers.

Analytics and Advertising

Matarus uses Google Tag Manager, Google Analytics, and Google advertising services on its public website only — the marketing pages and the sign-in, sign-up, and purchase pages. These services are not loaded on signed-in pages of the Matarus application, so they do not observe a Student’s use of the Services.

For these services Matarus is the controller of the information it collects, and Google may act as an independent or joint controller for its own purposes rather than as a sub-processor of Matarus. The information involved is IP address, cookie and device identifiers, page addresses, referral information, and advertising-conversion signals. Google’s handling of that information is governed by its own terms and privacy notices.

Communications Networks

WhatsApp messages are delivered through the WhatsApp Business Platform, so Meta Platforms processes the recipient's WhatsApp address, message or notification content, delivery status, and message-template information for every WhatsApp message. Meta acts as a sub-processor for WhatsApp delivery and is listed in the table above.

SMS and WhatsApp messages may additionally pass through telecommunications carriers, network operators, and other communications intermediaries needed to reach the recipient. Those parties may process addressing information, message or notification content, routing information, delivery records, and abuse-prevention data under their own legal and network obligations. Unlike Meta, they are not sub-processors of Matarus or Twilio — they carry the message under their own network and regulatory obligations.

Twilio maintains its own list of downstream sub-processors (opens in a new tab). That list may change independently of this page.

Changes to This List

We review this list as our services and providers change. We will update this page when we add or replace a sub-processor that processes personal information covered by this notice. Customers with contractual notification or objection rights will receive notice in accordance with their agreement with Matarus.

Questions or objections concerning a provider or international transfer may be sent to privacy@matarus.com.
