Privacy Policy
At Veltstack we process personal data transparently, proportionately and only as needed. This policy explains what we collect—and how we use it—when you visit our site, fill out a form or get in touch.
Last updated: July 19, 2026
1. What This Policy Covers
Your privacy is part of how we work with you. This policy summarises what data we collect, why we process it, who we share it with (and when), and how you can exercise your rights.
We do not collect data for unrelated purposes and we do not sell marketing lists. We use data to communicate, deliver services, keep the site secure and meet legal obligations.
2. Data Controller
The data controller under this Privacy Policy is Ömer Halis Demir, operating under the Veltstack brand.
3. What Data We Collect
Until we know you, we typically work with the information you choose to share. The categories below are the ones that most often apply:
- Identity and contact: full name, email address, phone number
- Request content: project summary, service you need, budget range and message text
- Technical data: IP address, browser and device details, session logs and essential cookies
- Analytics data: page views and on-site interaction statistics (only when your cookie preferences allow it)
4. How We Use Your Data
We process personal data for the following purposes:
- Responding to enquiries and managing the quotation process
- Running pre-contract discussions, delivering services and coordinating projects
- Keeping the site secure, preventing abuse and fixing technical issues
- Meeting legal obligations
- Understanding site performance and improving experience (with your consent where required)
5. Legal Bases
Processing is grounded in the legal bases set out in Article 5 of Turkey’s Personal Data Protection Law (KVKK): establishing or performing a contract, complying with a legal obligation, protecting our legitimate interests and, where needed, explicit consent.
Marketing or promotional messages are sent only with your explicit consent; you may withdraw that consent at any time.
7. How Long We Keep Data
We keep data for as long as the processing purpose continues and as required by applicable limitation periods. When the purpose ends or the retention period expires, we delete, destroy or anonymise the data.
Contact and quotation records are generally kept for up to 2 years after the last interaction. Records we must retain by law are kept for the statutory period.
8. Your Rights
Under the KVKK you may ask whether your data is processed, request information if it is, request correction or deletion, learn who it has been shared with, object to processing and claim compensation for damage caused by unlawful processing.
Send requests to veltstack@outlook.com with enough detail for us to verify your identity. We respond within 30 days at the latest.
9. Security Measures
We apply proportionate technical and organisational measures to protect personal data against unauthorised access, loss, alteration or disclosure—including HTTPS, access control, secure hosting and regular backups.
No system can promise absolute security; we commit to maintaining reasonable, up-to-date safeguards. If a breach is suspected, we will notify you and the competent authorities to the extent required by law.
11. Children’s Privacy
Our services are not directed at anyone under 18. We do not knowingly collect personal data from children under 18. If we become aware that we have, we will delete it.
12. Policy Updates
We may update this policy as our services, legal requirements or infrastructure change. The current version is always published on this page; significant changes may also be announced on the site.
