Leron
Call recording notice
How calls answered or placed by our AI assistant are recorded and handled. Last updated 12 October 2026.
Who this is about
Leron provides Hana, an AI assistant that answers phone calls for restaurants. When you call a restaurant that uses Leron, the restaurant is the controller of your data, and Leron processes it on the restaurant's behalf and on its instructions. This notice explains what happens to your call.
When you ask Hana to call you
On leronsystems.com you can leave your name, your restaurant and a phone number, and ask Hana, Leron's AI assistant, to call you. Tapping Call me confirms the number is yours and is your agreement to that one call, straight away, about Leron. For this call Leron is the controller of your data, and our lawful basis is your consent. You can withdraw it at any time by hanging up, telling Hana, or emailing us.
- We keep a record of the request: the number, its country, the time, the exact words you agreed to, and a salted hash of your IP address. We never keep the address itself.
- Hana tells you at the start that the call is recorded, and the call is then handled as described on the rest of this page.
- We call a number at most once a day, only between 8am and 9pm where it rings, and never a number that costs extra to call.
- Requests are deleted 12 months after they are made.
What we collect
- The phone number you call from, and the date and time of the call.
- A recording of the call and a written transcript of it.
- Details you give to make a booking or enquiry: your name, contact number, party size, time, and any preferences or requests you mention.
Why we record, and how AI is used
Calls are recorded so the restaurant can take and confirm your booking, answer your enquiry, resolve any dispute, and improve its service. We also use AI to transcribe and understand the call so Hana can help you and the restaurant can review what was said. This AI analysis is a separate activity from the recording itself, and we set it out here in line with the ICO's guidance. Before Hana answers, you hear: “Just so you know, calls may be recorded to help with your booking.” We ask for your name rather than identify you by your voice.
Our lawful basis
The restaurant, as controller, decides the lawful basis for recording and handling your call. This is usually its legitimate interests in answering and managing its calls, balanced against your rights. The restaurant's own privacy notice says which basis it relies on.
How long we keep it
We keep conversation history, including call recordings, until you or the restaurant ask us to delete it. That history is the recording, transcript and summary of each call, and any texts, WhatsApp messages or emails.
The same goes for your booking history with the restaurant and details you asked them to remember, such as an allergy or a usual order, so they can look after you properly next time.
To have any of it deleted, ask the restaurant, or email us at the address below. Counts and totals that no longer identify anyone, such as how many bookings a restaurant took in a week, are kept.
Your rights
You can ask, at any time, for a copy of your call data, or for it to be corrected or deleted. Ask the restaurant you called, or email us at the address below and we will pass it to the restaurant and act on its instructions. We aim to answer within one month.
Who we share it with
We use a small number of service providers to run Hana: Twilio carries the call and plays the recording notice; ElevenLabs runs Hana's voice, keeps the recording, and writes the transcript and summary; OpenRouter passes the transcript to the AI models, made by Anthropic, OpenAI and Google, that sort the call and draft any follow-up; and Supabase holds the transcript and your booking in our database in London. Some of these providers process data outside the UK, including in the United States, under the safeguards our privacy notice names. We do not sell your data or use it for advertising.
