Last updated: 3 November 2026

This privacy notice is prepared by Versiyonbir Teknoloji as data controller under Article 10 of the Personal Data Protection Law No. 6698 (KVKK) and the Communiqué on the Procedures and Principles to Be Followed in Fulfilling the Obligation to Inform. It tells everyone who visits our site or contacts us how their personal data is processed.

Your personal data is processed by Versiyonbir Teknoloji, based in Ankara, as data controller. You can reach us about anything concerning your personal data at info@versiyonbir.com. The controller's details:

Personal data we process

We process your personal data in these categories:

Identity: your first and last name.
Contact: your e-mail address and, if you share it, your phone number.
Professional: the name of the company you work for or represent.
Request: your message, the service you are interested in, the language and address of the page you sent the form from, and the time it was sent.
Transaction security: in our request records, a salted hash of your IP address, never the address itself; in server logs, the IP address, browser details, the requested address and the time.
Booking, when call booking is offered: your name, e-mail address, notes, the time you chose and your time zone.
Chat, when you use the chat assistant: the messages you type, your voice if you turn the microphone on, the assistant's replies, your language choice and the technical data a connection needs; the details are under "Chat assistant" below.
Visit statistics, if we measure visits: the page viewed, the referring address, browser and device type, and country; these are derived from your browser's page request without cookies, and we see only aggregate figures.

Please do not send us special categories of personal data (KVKK Article 6), such as data on health, religion, ethnic origin, political opinion or criminal convictions.

How we collect personal data

We collect your personal data orally and electronically, partly by automated means, through these channels:

The contact form.
E-mail.
Phone.
WhatsApp, when offered: your phone number, profile name and messages; WhatsApp's own terms also apply on this channel.
The call booking form, when this feature is offered.
The text and voice chat window at the bottom right of our site; the details are under "Chat assistant" below.
Server logs and, if we measure visits, cookieless visit statistics.

Purposes of processing

We process your personal data for these purposes:

Answering your request and preparing an offer for you.
Answering your questions in the chat assistant and, in a voice conversation, turning your speech into text and the replies into speech; the details are under "Chat assistant" below.
Pre-contract communication and following up your request in our records.
Keeping the site secure and preventing unwanted and malicious submissions.
If we measure visits, seeing how the site is used through aggregate statistics.
Meeting our legal obligations and answering requests from the authorities.
Taking the steps needed to establish, exercise or protect a right.

Legal grounds

We process your personal data for these purposes on the following legal grounds of Article 5(2) of the KVKK:

(c) Processing is directly related to establishing or performing a contract, where processing the contracting parties' personal data is necessary: answering your request and the questions you ask the chat assistant, preparing an offer and pre-contract communication.
(ç) Processing is necessary for us to meet a legal obligation: legal obligations and requests from the authorities.
(e) Processing is necessary to establish, exercise or protect a right: the steps we take to establish, exercise or protect rights.
(f) Processing is necessary for our legitimate interests, provided it does not harm your fundamental rights and freedoms: following up requests in our records, site security, preventing abuse, aggregate statistics if we measure visits, and answering your request when you write on behalf of a company.

On this site we base no processing of personal data on explicit consent, and we do not ask for special categories of personal data.

Chat assistant

The text and voice chat window at the bottom right of our site is an AI assistant that answers questions about Versiyonbir Teknoloji's services. When you open it, your browser connects to the real-time communication server (LiveKit) we run on our own server; our server is in Hetzner Online GmbH's data centre in Helsinki, Finland.

What is processed

The text you type; your voice, only while you keep the microphone on; the assistant's replies; your browser's language or the language you pick; the technical data a connection needs (IP address, browser details). The microphone turns on only when you press its button and off whenever you choose; no camera image or screen is captured. The assistant does not ask for personal data; personal data you type yourself is processed only to produce the replies in that conversation.

Purpose

Answering your questions; in a voice conversation, turning your speech into text and the replies into speech.

Transfer abroad

In the chat, your data is sent to these providers established abroad:

Anthropic, PBC (USA), the Claude language model: your typed messages, in a voice conversation the transcript of your speech, and the assistant's replies, to produce the replies.
Deepgram, Inc. (USA): the audio of your voice, only while the microphone is on, to turn your speech into text.
ElevenLabs, Inc. (USA): the text of the replies, to turn them into speech.
Microsoft Corporation (USA): the text of the replies when ElevenLabs cannot be reached, to turn them into speech; this fallback uses Microsoft's publicly available Edge read-aloud service, under Microsoft's own terms.

These transfers rest on the conditions set out under "Transfers abroad" below. The providers may keep data for a limited time under their own privacy terms: Anthropic, Deepgram, ElevenLabs and Microsoft.

Retention

Our chat server stores no conversations; the session is deleted shortly after you close the window. Technical logs keep random session identifiers and the language and voice switches for a short time, and the connecting IP address only when the request limit is exceeded; message content is not logged.

Stored in your browser

The chat window sets no cookies. When you press the language button it saves your choice in your browser's local storage (vb-chat.lang); it remembers that you opened the window until the tab closes (vb-chat.opened), so the icon does not move again in this tab. These entries do not identify you and are shared with no one.

For your rights and how to exercise them, see the relevant section of this notice.

Recipients and service providers

We transfer your personal data to the recipients below, and only as far as the purposes above require. The service providers process the data on our behalf.

Hosting, server functions and server logs: Vercel Inc. Our functions run in Frankfurt; pages are served through Vercel's global network.
The database that holds our request records: Neon.
Transactional e-mail (the notification to our team): Resend.
Our business e-mail provider (mail to our info@versiyonbir.com address and team notifications).
Call booking, when this feature is offered: Cal.com.
Cookieless visit statistics, if we measure visits: Vercel Web Analytics.
Chat assistant: our own server (Hetzner Online GmbH, Helsinki, Finland) with Anthropic, Deepgram and ElevenLabs; Microsoft for the fallback voice.
Competent public authorities and courts, where the law requires.

We do not sell your personal data and do not share it with anyone for advertising.

The AI providers used in the automations we build for our clients are chosen for each project and named in our contract with that client. On this site, AI providers are used only by the chat assistant described under "Chat assistant" above; no other part of the site sends personal data to them.

Transfers abroad

Our hosting, database, mail-delivery and booking providers and the chat assistant's providers (Anthropic, Deepgram, ElevenLabs and Microsoft) are established in the United States, and our own chat server is in Finland, so your personal data is transferred abroad. If our business e-mail provider is established abroad, transfers to it rely on the conditions below as well. Our server functions on Vercel run in the European Union, in Frankfurt; pages are served to you from the nearest point of Vercel's global network.

We make these transfers in line with Article 9 of the KVKK as amended by Law No. 7499, relying on one of the legal grounds in Article 5 and on one of the following conditions:

An adequacy decision of the Personal Data Protection Board for the country of transfer.
Where there is no adequacy decision, one of the appropriate safeguards the article lists, such as the standard contract announced by the Board.

Retention periods

We keep your personal data only as long as necessary:

Request records (including booking data) and the e-mails about them: 12 months from the last action on the request. They are then deleted or anonymised under the Regulation on the Deletion, Destruction or Anonymisation of Personal Data.
If a contract follows, the records about it: for the periods commercial and tax law set.
The salted IP hash and server logs: at most 30 days.
Chat assistant: our chat server stores no conversations; its technical logs hold no message content and are kept for a short time. The details are under "Chat assistant" above.
