Questions and answers

Is it legal to record phone calls?

Whether you can record a phone call depends on your country’s laws, so always tell the other person you are recording.

Where are iPhone call recordings?

iPhone call recordings are saved in the Notes app, in the Call Recordings folder.

How much of a call recording is free?

Kalpa transcribes the first 2 minutes of any phone call recording for free; the rest of the call is in the Kalpa app.

Can Kalpa transcribe calls in other languages?

Kalpa detects the language of a call recording automatically and supports 25 languages, including Spanish, Polish, Ukrainian and Croatian.

Is my call recording stored?

Kalpa deletes the call audio right after the transcript is made; the text is kept for 24 hours so the same recording isn’t processed twice, then deleted, and Kalpa does not use it to train models.
