Privacy Policy

Last updated: November 2, 2026

This policy explains how Semih Turna ("I") handles personal data when you visit semihturna.com, send a request through the contact form, or work with me. Visitors in Türkiye can also read the KVKK notice in Turkish.

What I collect

• Contact form: your name, e-mail address and request; optionally your company or brand, phone number, how you handle the job today, timeline, budget range and preferred way of contact.
• Where your visit came from: the page your visit started on, the address of the page that linked to this site, and campaign tags (utm) if the link had them.
• Security check: Cloudflare Turnstile processes technical data such as your IP address and browser details to confirm that a person sent the form.
• Site statistics: Cloudflare Web Analytics records aggregate data such as page views, referring sites, country and page speed, without cookies and without building a profile of you.
• Ad and usage measurement (Google Consent Mode v2): the Google Ads tag and Google Analytics (Google LLC) load on every visit, but they use no cookies or persistent identifiers unless you press "Accept" in the cookie banner; until then only cookieless, anonymous aggregate signals (page views, clicks on demo and contact buttons) are sent to Google, which may use them for aggregate statistical modelling. If you accept, cookies may be set and your IP address and browser details may be processed to measure how my ads perform and how the site is used. If you decline, Google cookies are deleted and not set again; you can change your choice at any time with the "Cookie preferences" button at the bottom of the page.
• Work together: the files and details you send me for a job.
• E-mails you send me.

How I use it

To answer your request and talk with you about the software or a possible job, to keep the form free of abuse, and to see which channels bring visitors and how fast the site loads. I do not sell your data to third parties for commercial purposes, and I do not use it to profile you. If you accept the Google Ads tag and Google Analytics, Google may use their data to measure the performance of my own ads and the use of this site.

Service providers

The contact form is processed by Vercel Inc. (USA); the site, the security check and the statistics run on Cloudflare, Inc. (USA); if you accept the ad and usage measurement tags, Google LLC (USA) also receives the data described above; requests reach me by e-mail at my semihturna.com mailbox. Your data may therefore be processed outside Türkiye. The position of these transfers under Turkish law (KVKK Article 9) is being assessed separately; the form asks for no consent for them. Your data may be shared with the service providers named above and with my e-mail hosting provider as needed to run the service, and with authorised public bodies to the extent the law allows or requires. Sending the form creates no order, contract or payment.

Retention and your rights

Requests that do not lead to work together are deleted at the latest one year after I reply. If we later work together, records of the work are kept as long as the law requires. You can ask me to access, correct or delete your data at any time by e-mailing info [at] semihturna.com.

Free tools

In the site's free tools (WhatsApp message and link, QR code and QR menu, cost, VAT and expense-split calculators, price labels), the names, phone numbers and amounts you type are processed only in your browser; they are not sent to my servers and are gone when you close the page. In the credit ledger, daily cash book and barcode stock tools, the records you enter (customer names, phone numbers, amounts, product list) are kept only in the browser storage (localStorage) of the device you use; they are not sent to my servers and are lost if you clear browser data; a backup file you download stays with you and protecting the personal data inside it is your responsibility. The barcode tool’s camera opens only when you press “Open camera” and allow it in the browser prompt; the picture is not recorded or sent. In the QR menu tool the menu travels in the part of the QR address after the # sign, which is not sent from the browser to a server. When you open a WhatsApp link, the number and message pass to the WhatsApp app on your phone. For measurement, and in line with your cookie choice, an event containing only the tool's name and the page path may be sent to the Google tag; what you type is not sent.

Cookies

Without your consent this site sets no tracking or advertising cookies; Cloudflare Web Analytics is cookieless. If you press "Accept" in the cookie banner, the Google Ads tag and Google Analytics are loaded and may set cookies such as _gcl_* and _ga. Pressing "Decline" or leaving the banner unanswered keeps the tags off. Your choice is stored in your browser (st_consent) and you can change it at any time with the "Cookie preferences" link at the bottom of every page; declining after accepting also removes the Google cookies this site set.
