Privacy Notice and Data Deletion

For the tavexus.com website and the Tavexus programs · Last updated: 01.11.2026

1. Data controller

Under Turkish Law No. 6698 on the Protection of Personal Data ("KVKK"), the data controller is Mehmet Şeref Dağ — Tavexus Yazılım, Muratpaşa / Antalya, Türkiye. Contact: info@tavexus.com, +90 545 430 19 69.

2. What personal data is processed?

• Contact details: name, business name, city, phone number, e-mail address and message content that you share when you contact us by WhatsApp, phone or e-mail.
• Technical logs: the website is hosted on GitHub Pages (GitHub, Inc.). For security and operation, the host may keep access logs (such as IP address, date and time, browser information). These logs are not passed on to us.

The "Quote and free trial" form on this website does not store your details and does not send them to a server; it only opens a prepared message in WhatsApp. Whether you send that message is up to you.

3. Purposes

• Answering your questions and your requests for quotes and free trials,
• Planning installation, training and support appointments,
• Handling contracts and invoicing if you request them,
• Meeting our legal obligations.

4. Legal basis

Your personal data is processed under KVKK Article 5(2): it is directly related to concluding or performing a contract (c), it is necessary to meet our legal obligations (ç), and it is in our legitimate interest provided this does not harm your fundamental rights and freedoms (f).

5. Transfers

Your personal data is never sold. It may be shared only with public authorities where the law requires it, and as far as needed to provide our service (for example with our accountant for invoicing). WhatsApp and e-mail run on the infrastructure of their providers (Meta Platforms, Google); when you use these services, the providers' own privacy terms also apply.

6. How data is collected

Data is collected electronically and by non-automated means when you contact us by WhatsApp, phone or e-mail of your own accord.

7. Retention

Communication records that do not lead to a contract are kept for at most 2 years. Where a contract is made, data is kept for the periods required by law (for example the Turkish Tax Procedure Law and Commercial Code) and is then deleted or anonymised.

8. Your rights (KVKK Article 11)

By contacting us you can find out whether your personal data is processed and request information about it; learn the purpose of processing and whether it is used accordingly; know the third parties it was transferred to; ask for incomplete or incorrect data to be corrected, and for data to be deleted or destroyed; ask for these actions to be notified to third parties it was transferred to; object to a result against you that arises from automated analysis; and claim compensation for damage caused by unlawful processing.

Send your requests to info@tavexus.com. They are answered free of charge within 30 days at the latest.

9. Cookies

This website uses no cookies and contains no visitor statistics, advertising or social media tracking code. All files, including fonts, are loaded from the website itself.

10. Data in our programs

Tavexus programs are installed on our customers' own computers. Customer, sales and document data entered into the programs stays on that business's computer and is not sent to Tavexus Yazılım. The business that uses the program is the data controller for this data.

This section applies to Tavexus Inventory, Promissory Notes, Rentals, Building Manager, Studio, Phone Shop, DocFinder, e-Invoice Desk and LokmaPOS. Tavexus Social Manager, which connects to Facebook, Instagram and YouTube accounts, has its own privacy policy: Social Manager privacy policy and data deletion instructions (Turkish and English).

11. License request code and support code

To get a license or ask for support, you send us the license request code or support code shown in the program yourself (by WhatsApp or e-mail). These codes contain only the installation ID, program name and version, trial / license status and date information; they contain no customer, sales or document data. The program never sends them to us on its own. Our license and contract records hold only this information plus your business name and contact details.

12. Automatic updates

At night the programs check GitHub (GitHub, Inc.) for a new version and download it if there is one. Nothing from the program's data is sent during this check; GitHub may only keep technical logs of the download request (such as IP address, date and time). These logs are not passed on to us.

13. Deleting your data

• Data in the program: this data exists only on your computer; Tavexus has no copy. To delete it, delete the records in the program, or uninstall the program and delete its data folder (including backups). Tavexus cannot access this data and therefore cannot delete it for you.
• Your records at Tavexus: you can ask for your contact, quote, license and contract records to be deleted by writing to info@tavexus.com. Records still within a legal retention period (e.g. invoices) are deleted when that period ends; all others are deleted within 30 days and we will let you know.
