Subprocessors
Last updated: October 29, 2026
The short version
- These are the kinds of companies that help us run TextKit and what each one sees.
- Customers under our DPA can get the named list from support@joinsimplesms.com, and can ask to be notified before it changes.
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. 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.
