Built for the calls you can’t leak.
Sales calls carry names, phone numbers, prices and promises. Here is exactly how CallSight protects them — in plain words.
In the EU. In one place. Isolated.
Call audio, transcripts, scores and the search index behind Echo are stored in Frankfurt, Germany, on Supabase. Data is encrypted in transit and at rest. Calls only leave that home to be transcribed and analyzed by the AI providers listed below — and come straight back.
Who processes what
| Provider | What it does for CallSight | When |
|---|---|---|
| Supabase | Database, file storage and server functions (EU — Frankfurt) | Always |
| OpenAI | Transcribing calls; building the search index Echo uses | Every call |
| Anthropic | Analyzing and scoring calls; answering as Echo | Every call, every question |
| Vercel | Hosting the CallSight app | Always |
| Cloudflare | Website hosting, demo-request storage and notification delivery | Website only |
| Email inbox for responding to demo requests | Demo requests only | |
| monday.com | Receiving call summaries in your CRM | Only if you connect it |
| WhatsApp messaging provider | Sending lead alerts to your team | Only if you turn alerts on |
OpenAI and Anthropic are used through their business APIs, which do not use your data to train their models.
Recording consent
Whether a call may be recorded depends on where you and your customers are. CallSight records the calls that pass through the line you connect; telling customers that a call is recorded, where required, is your team’s responsibility. We’re happy to walk through how other teams handle it.
