# Sub-processors

**Last Updated:** September 5, 2026

AddCal uses the third-party sub-processors listed below to help us provide our Services. Each sub-processor only processes Personal Data as needed to perform the services we have engaged it for, and is subject to a data processing agreement with data protection obligations consistent with our [Data Processing Addendum](/dpa) and [Privacy Policy](/privacy-policy).

| Sub-processor | Purpose | Processing location |
| --- | --- | --- |
| Amazon Web Services (AWS) | Hosting, compute, database, storage, and email delivery (SES) | United States |
| Stripe | Payment processing | United States |
| Sentry | Application error monitoring | United States |
| PostHog | Product analytics | United States |
| Intercom | Customer support and messaging | United States |
| Bento | Email and lifecycle communications | United States |
| Google Cloud | AI and machine learning services (including spam and abuse detection) | United States |

"Processing location" refers to the region in which the sub-processor stores and processes Personal Data on our behalf. Where Personal Data is transferred outside the European Economic Area, the United Kingdom, or Switzerland, we rely on the safeguards described in our [Data Processing Addendum](/dpa).



We may update this list from time to time as our Services evolve. The "Last Updated" date above reflects the most recent change. If you would like to be notified of changes to our sub-processors, please contact us at **support@addcal.co**.

We give at least 30 days' notice before adding or replacing a sub-processor. If you have a reasonable, data-protection-based objection to a new sub-processor, let us know within 30 days and we will work with you in good faith to address it, as set out in our [Data Processing Addendum](/dpa).
