Privacy policy
Effective: November 9, 2026
WINTELL processes the following information to provide blinds consultations and arrange in-home services.
Information and purpose
We collect your name, phone number, installation area and district, room, preferred contact time, site language and preferred consultation language. Product preferences, selected fabric samples, color preferences, comparison choices, customer measurements, messages and photos are optional. We use the information for consultations, quotations, visit scheduling and communications about contracts and installation. A detailed address may be collected when arranging a visit.
Encrypted backups
Encrypted recovery copies of consultations, visits and attachments may remain for up to seven days. Additional encrypted copies may be stored on the operator’s device with the same retention period. Requests marked permanently deleted are excluded from normal missing-record recovery.
Retention and deletion
Consultation information is retained for up to one year after the consultation ends, then deleted. Records related to a concluded contract may be retained separately as required by the contract and applicable law. The operator reviews and deletes records and photos when no longer needed. Deletion requests are reviewed for any required retention.
Service infrastructure
We do not sell customer information or provide it for advertising. When notifications are connected, we send the reference, broad service area, product category, preferred language and last four phone digits to the operator’s Telegram chat. Names, full phone numbers, detailed addresses and photos are excluded from notifications. OpenAI Sites and its underlying Cloudflare infrastructure host the site, database and photo storage. Consultation information and photos are accessible only to authorized administrators. We do not use external map, analytics or advertising tracking scripts.
Consent and your rights
You may refuse to provide the required information, in which case online consultation requests are unavailable. You can request access, correction, deletion or restriction of processing using the contact details below.
Visit statistics
Our own server measures referral hostnames or restricted campaign tags, pages, products, language, device categories and successful consultation submissions for up to 90 days. A daily rotating HMAC identifier estimates visits; raw IP addresses, full browser details and long-term tracking cookies are not stored. A submitted consultation may be linked to that day’s visit identifier. We honor browser Do Not Track (DNT/GPC). Statistics are optional and do not affect your ability to submit a request. Administrator and test visits are excluded from customer statistics.
Cookies and security
A cookie remembers your language preference. Single-use security checks and daily-hashed connection data help prevent spam. Blocked-request records are retained for up to seven days. Cloudflare Turnstile is used when additional bot verification is connected. Administrator sign-in uses ChatGPT authentication, and only the authorized administrator can access consultation records and photos. Applicants cannot view other customers’ records.
