Privacy policy
Kalyo is a Human Echo Connect product. This page explains simply what data we collect, why, for how long, and how to have it deleted.
Data we collect
We only collect what is necessary to respond to your request or to run the voice agent during a demonstration:
- Contact form: name, phone number, industry provided, and the content of your message if you leave one.
- Demo call request ("Have our AI call you"): your phone number, used once for the test call.
- Calls handled by the agent (Kalyo product customers): conversation transcript, information relevant to the request (address, requested slot, reported emergency), and an audio recording for the duration of processing, in line with what is announced to you at the start of the call.
- Browsing: light/dark display preference, stored only in your browser's local storage (see "Cookies & local storage").
What this data is used for
- Responding to your contact or demo request;
- Scheduling and running a test call you requested;
- Running the voice agent during a real call (taking bookings, triaging emergencies, booking appointments) when you are a Kalyo product customer;
- Improving the quality of the service (anonymised analysis of latency, speech recognition and answer relevance).
We never use your data for unsolicited marketing, advertising profiling or resale to third parties.
Legal basis for processing
Depending on the case, processing relies on your consent (form checkbox, voluntary request for a test call), on steps taken at your request prior to or under a contract (if you become a Kalyo product customer), or on our legitimate interest in responding to a request you send us spontaneously.
Retention periods
- Contact and test-call requests that don't lead anywhere: 12 months maximum, then deleted or anonymised.
- Data linked to an active customer account: kept for the duration of the contract, then 12 months after the relationship ends.
- Call recordings and transcripts: kept for a maximum of 90 days, unless a different duration is agreed with a customer to improve their own agent.
You can request early deletion at any time (see "Your rights").
Recipients and hosting
Your data is processed by the Kalyo team and by the technical providers strictly necessary to the service (hosting, telephony, voice engine), all bound by confidentiality commitments. It is never sold, rented or shared with third parties for commercial purposes.
Hosting and processing take place within the European Union. If a non-EU provider were ever used, we would ensure a compliant transfer framework (standard contractual clauses or equivalent) and inform you.
If you book a time slot from the Contact page, the booking is handled by Cal.com, our scheduling tool. The calendar only loads after you agree; the information you enter (name, email, phone, chosen slot) is then sent to Cal.com to arrange the appointment. If this data is processed outside the European Union, the transfer is covered by the safeguards provided for by the GDPR (adequacy decision or standard contractual clauses).
Cookies and local storage
This site uses no advertising cookies and no third-party analytics trackers. It only uses your browser's localStorage to remember your display preference (light or dark theme). This information stays on your device, is never transmitted to our servers, and can be cleared at any time by clearing site data in your browser.
Your rights
Under the General Data Protection Regulation (GDPR), you have the following rights over your personal data:
- Right of access to and communication of data concerning you;
- Right of rectification of inaccurate or incomplete data;
- Right to erasure ("right to be forgotten");
- Right to restriction of and objection to processing;
- Right to data portability;
- Right to withdraw your consent at any time, without retroactive effect;
- Right to lodge a complaint with a supervisory authority, such as the French CNIL (www.cnil.fr) or your own country's data protection authority.
To exercise any of these rights, write to us at contact@kalyo.ai. We reply within one month, and may ask you to prove your identity if needed.
Artificial intelligence (AI Act)
Kalyo is a conversational artificial intelligence system. In accordance with Article 50 of Regulation (EU) 2024/1689 on artificial intelligence (AI Act), every caller is told at the start of the call that they are interacting with an AI, and the agent's voice is generated by speech synthesis. No decision producing legal effects or similarly significantly affecting you is taken solely by automated means: each call is passed on as a call record to the business you contacted, which decides on any follow-up. Kalyo performs no emotion recognition, no biometric categorisation and no profiling of callers.
Data security
We implement reasonable technical and organisational measures (encrypted exchanges, access restricted to relevant teams, European hosting) to protect your data against unauthorised access, loss or alteration. These measures are continuously strengthened as the product develops.

For any question about this policy or your data, contact us at contact@kalyo.ai or via our Contact page. This policy may evolve along with the Kalyo product; the update date at the top of the page is authoritative.
