Subprocessors are third parties that may process Customer Personal Data on
our behalf. Each is bound by data protection terms at least as protective as
our [DPA](/dpa). We list them by category here; the named list, with each
provider's entity and location, is available to customers on request and is
confidential.

| Category | What it does | Data it processes | Location |
| --- | --- | --- | --- |
| Telecommunications carriers and aggregators | Transmit SMS and MMS, provision and port numbers, return delivery receipts | Phone numbers, message content and media, message metadata | United States, Canada |
| Messaging registries | Register brands and campaigns (A2P 10DLC, toll-free verification) as carriers require | Customer business details, campaign descriptions, sample messages | United States |
| Cloud infrastructure and database | Host the API, console, and database | All Service data | United States |
| AI moderation and classification | Screen outbound content for prohibited material; classify ambiguous inbound replies as opt-outs; draft registration suggestions from the public web pages a customer submits ([Privacy §4](/privacy)) | Message content, and text from public web pages a customer submits for registration; transiently, with no training on either | United States |
| Phone data provider | Carrier and line-type lookups | Phone numbers looked up | United States |
| Payment processor | Billing and payments | Account and billing data | United States |
| Email delivery | Account and service email | Account email addresses | United States |
| Product analytics | Website and console usage, with consent; account-level usage metrics (counts, timings, revenue estimates, per-message delivery status) sent from our servers for business reporting ([Privacy §8](/privacy)) | Account and message identifiers, usage counts, delivery status; never message content or recipient numbers | United States |
| Operations tooling | Internal alerts for billing and account events | Account identifiers; never message content | United States |

## Changes

We give at least 10 days' notice before a new subprocessor processes Customer
Personal Data, to customers who have asked for notices at support@joinsimplesms.com,
and update this page. Customers may object as described in the [DPA](/dpa)
§7.
