This page explains which personal data is collected through devkadogalgaz.com, for which purposes and on which legal grounds it is processed, who it is shared with, how long it is kept, which cookies the site uses, and what rights you have under Turkish Personal Data Protection Law No. 6698 (KVKK).

Data controller

The data controller for your personal data is the business identified below. “We” and “our company” in this notice refer to that business.

Legal name	DEVKA DOĞALGAZ BURAK DEVECİ-KORAY KAYA
Address	Bayındır Mah. 322. Sk. No:24/1, 07030 Muratpaşa/Antalya
Phone	0553 028 82 80
E-mail	info@devkadogalgaz.com
Website	www.devkadogalgaz.com

What data we collect

The site has no membership, user accounts, online payment or comments. Personal data is collected only when you contact us. The contact form collects the following fields:

Data	Where it is collected	Status
Full name	Contact form	Required
Phone number	Contact form	Required
E-mail address	Contact form	Optional
District	Contact form (select from list)	Optional
Subject	Contact form (select from list)	Optional
Message text	Contact form	Required
Date and time of submission	Automatic on submission	Recorded automatically
Short irreversible digest of the IP address	Automatic on submission	Recorded automatically

When you submit the form, these details are both written to a log file on our server and sent by e-mail to info@devkadogalgaz.com. If you entered an e-mail address, it is added to the “reply-to” field of that e-mail so we can answer you directly.

We do not store your IP address as such. To prevent a large number of submissions from the same connection in a short time, a short irreversible digest derived from the IP address is stored together with the submission time in a separate counter file; that record is deleted after 10 minutes.

If you reach us directly by phone, WhatsApp or e-mail, the details you share in that message are processed for the same purposes.

Values you enter into the boiler kW and radiator calculators on this site are computed in your own browser only; they are not sent to our server and are not stored. Only if you click “request a quote with this result” are the values carried into the message field of the contact form; if you then submit the form, they are processed as form data.

As with every website, technical access records (request time, requested address, IP address, browser information) are generated on the server of our hosting provider. These records are kept by the provider for system administration and security; we do not use them for marketing, profiling or analytics.

Why we process it

We use the data we collect only for the following purposes:

Responding to the request you send through the contact form, phone, WhatsApp or e-mail
Scheduling the free site survey and appointments
Preparing a quotation for your request and sending it to you
Carrying out the installation, maintenance or service work and staying in touch with you throughout, if your request turns into a job
Preventing automated abuse of the contact form and keeping the site secure

We do not use your data for anything beyond these purposes. We do not send you advertising or bulk marketing messages without your consent, and we do not sell your data.

Legal grounds and collection method

Your personal data is collected electronically, by partly automated means: through the contact form when you fill it in and submit it, or through the relevant channel when you reach us by phone, WhatsApp or e-mail.

Our processing relies on the conditions listed in Article 5(2) of the Law:

Art. 5(2)(c): Processing is directly related to the conclusion or performance of a contract. Your survey, quotation and job request are part of pre-contractual discussions.
Art. 5(2)(ç): Compliance with a legal obligation of the data controller. Keeping documents for the periods required by law once a job turns into a contract or invoice falls here.
Art. 5(2)(f): The legitimate interests of the data controller, provided this does not harm your fundamental rights and freedoms. Keeping a record of requests, tracking request history and preventing abuse of the form fall here.

The consent box on the form is there to confirm that you have read this notice and accept that your contact details will be used to reply to your request. Because the legal grounds above are sufficient, we do not additionally rely on your explicit consent.

We do not collect special categories of personal data such as health, religion or membership; please do not include such information in the message field.

Transfer of data

We do not transfer or sell your data to third parties for marketing. The limited and necessary cases where a third party comes into contact with the data are:

Hosting provider: Our website and e-mail service run on the servers of a hosting provider established in Türkiye. Because form records and incoming e-mails are held on that server, the provider is technically able to access the data as part of system administration. This transfer takes place within Türkiye; we do not transfer data abroad.
Google Maps: The map showing our office on the contact and home pages is content embedded by Google. When the map loads, your browser connects directly to Google servers; Google may receive your IP address and browser information and may set its own cookies. That connection is subject to Google’s own privacy policy and is outside our control.
Authorised public authorities: Only where required by law and limited to the information requested.

Google Privacy Policy

No data is transferred to any advertising network, analytics service or data broker.

Retention period

We keep each record only as long as the purpose it was collected for requires:

Record	Retention period
Contact form records and incoming e-mails	Up to 2 years after your request is closed
Documents of jobs that turn into a contract, quotation or invoice	The period required by law (5 years under tax legislation)
Form submission counter (IP digest and submission time)	Up to 10 minutes
Session cookie	Deleted when you close your browser
Server access records	A limited period set by the hosting provider’s system configuration

Records are deleted once the period ends. You may also request deletion before then; the application procedure is explained below.

Cookies

This site uses no advertising, tracking, analytics or social media cookies. No measurement tool such as Google Analytics or the Meta pixel is installed. All fonts, images, stylesheets and scripts are served from our own server; no external CDN is used.

The only cookie set by the site itself is the technical (strictly necessary) session cookie below:

Cookie	Purpose	Duration	Type
PHPSESSID	Cross-site request forgery (CSRF) protection on the contact form, displaying form error and success messages, keeping the short-term submission counter	Session	Strictly necessary / technical

This cookie carries only a randomly generated session identifier; it contains no name, phone number or message and is not used to track you across sites. It is deleted when you close your browser.

You can delete or block cookies in your browser settings. If you block the session cookie, the security check cannot run and the contact form will not work; in that case you can reach us by phone, WhatsApp or e-mail.

When the embedded Google Maps map loads, Google may set its own cookies. Those cookies do not belong to us, cannot be read by us, and are not loaded on pages without the map.

Your rights

Under Article 11 of the Law you may apply to the data controller and request the following:

To learn whether your personal data is processed
To request information if it has been processed
To learn the purpose of processing and whether the data is used in line with that purpose
To know the third parties in Türkiye or abroad to whom the data is transferred
To request correction if the data is incomplete or incorrect
To request erasure or destruction within the conditions of Article 7 of the Law
To request that correction, erasure or destruction be notified to the third parties the data was transferred to
To object to a result against you arising from analysis of the data solely by automated systems
To claim compensation if you suffer damage due to unlawful processing

No decision producing an adverse result for you is made on this site through analysis by automated systems alone.

How to apply

You can submit a request regarding your rights in line with the Communiqué on the Procedures and Principles of Application to the Data Controller, in the following ways:

In writing: a signed letter sent to Bayındır Mah. 322. Sk. No:24/1, 07030 Muratpaşa/Antalya (in person or through a notary).
