Sub-processors
Last updated 10 September 2026
The third parties we use to run WaveSenda, what each one receives, and where it is. We give 30 days' notice before adding one.
1Who receives what
| Provider | What it does | What it receives | Where |
|---|---|---|---|
| Contabo GmbH | The server everything runs on — application, database and stored media | Everything the service holds — accounts, messages, media, contacts | Germany (EU) |
| OpenAI, L.L.C. | AI agent replies, message classification, image descriptions | Message text and knowledge documents sent for a reply | United States |
| Voyage AI | Knowledge base search (embeddings) | Knowledge document text, and the question being answered | United States |
| Deepgram, Inc. | Voice note transcription and spoken replies, where enabled | Audio of voice notes sent to a connected number, and the text of spoken replies | United States |
| ElevenLabs Inc. | Spoken agent replies, where enabled | The text of replies an agent speaks aloud | United States |
| Stripe, Inc. | Card payments for subscriptions and credits | Billing name, email and payment details — card numbers never reach us | United States, Ireland |
2What none of them may do
None of these providers may use your data for their own purposes. In particular, the AI providers above operate under agreements that prohibit training models on content sent through them — which is why an agent reply costs money per message rather than being paid for with your conversations.
3Changes
We give 30 days’ notice by email and in the console before adding a sub-processor, so you have time to object before it receives anything. Removing one needs no notice.
Optional features are marked as such above: a provider only receives data if you have switched the feature on. Voice transcription is off by default, and card payments are only used if you pay that way.
