Sub-processors
Last updated 7 October 2026
In short. These are the companies that handle personal data for Presence, each for one job. We tell account owners by email at least 14 days before we add or replace one, and you can object.
Providers we use
Each provider’s name links to its privacy policy. We have contracts with each that limit it to its job and require it to protect the data.
| Provider | What it does | Data | Where |
|---|---|---|---|
| Telnyx LLC | Phone carrier: connects calls and texts to the public phone network, provides and moves numbers, submits texting registrations | Phone numbers, call audio in transit, call records, text messages, texting registration details, number-move paperwork | United States |
| Hetzner Online GmbH | Hosts our servers, database and recordings | All data held by Presence | Ashburn, Virginia, United States |

Providers you choose to connect
These receive data only if your business connects them, and on your instructions. Their own terms govern what they do with it.
| Provider | What it does | Data | Where |
|---|---|---|---|
| HubSpot, Inc. | Receives your call records, if you connect HubSpot | Call records and notes, matched to a contact by phone number | Per your HubSpot account |
| Apollo.io | Receives your call records, if you connect Apollo | Call records and notes, matched to a contact by phone number | Per your Apollo account |
Phone networks
To deliver calls and texts, other carriers handle them on their way to the people you reach, as on any phone network. To register a business for texting, its details go through Telnyx to The Campaign Registry and the mobile carriers, which the carriers require. These networks act under their own legal obligations, not as our sub-processors.
Changes
We email account owners at least 14 days before a new sub-processor starts handling personal data, or an existing one starts a new job. Under the Data Processing Addendum, you may object on reasonable data-protection grounds within that time by emailing support@redstonecastles.com. In an emergency, such as a provider failing, we may make a change sooner and will tell you as soon as we can.
