Privacy Policy

Effective from

This notice explains how we process the personal data of business partners and visitors on b2b.lumivix.cz, why, for how long, and what rights you have. It is provided under Articles 13 and 14 of Regulation (EU) 2016/679 (“GDPR”) and Czech Act No. 110/2019 Coll., on the Processing of Personal Data.

I. Controller

1.1.The controller is Lumivix Technologies s.r.o., registered office: Korunní 2569/108, 101 00 Prague 10, Czech Republic (Company ID (IČO) 30131553, registered in the Commercial Register kept by the Municipal Court in Prague, file number C 456947) (“LUMIVIX”, “we”).

1.2.For privacy matters contact us at info@lumivix.cz (business inquiries also at b2b@lumivix.cz) or in writing at our registered office.

1.3.We have not appointed a Data Protection Officer as we are not required to under Art. 37 GDPR.

1.4.This notice applies to b2b.lumivix.cz. The consumer site lumivix.cz has a separate notice (in Czech).

II. Purposes and legal bases

2.1. Partner inquiry

From the inquiry form we process your name, company name, business e-mail, expected volume, your message and the selected language in order to handle the inquiry, prepare an offer and discuss cooperation. Inquiries sent by e-mail are handled the same way.

The legal basis is taking steps at your request prior to entering into a contract (Art. 6(1)(b) GDPR); where you act on behalf of a company, it is our legitimate interest in communicating with contact persons of business partners (Art. 6(1)(f) GDPR). We do not send you marketing communications without your consent, except to existing customers as permitted by Section 7(3) of Czech Act No. 480/2004 Coll.

2.2. Inquiry source

We attach information about the campaign or website you came from to your inquiry. Campaign parameters are kept only in the memory of the open page until you submit the form; they are not stored in cookies or browser storage. For UTM parameters, landing page and referring site the legal basis is our legitimate interest in evaluating our marketing (Art. 6(1)(f) GDPR). Ad click identifiers (e.g. gclid, fbclid, li_fat_id) are attached only with your marketing-cookie consent (Art. 6(1)(a) GDPR). We do not store your IP address or browser identification with the inquiry.

2.3. Website operation and security

Our hosting provider processes technical data in server logs (IP address, date and time of the request, requested URL, browser type) to keep the site available and secure. The legal basis is our legitimate interest (Art. 6(1)(f) GDPR).

2.4. Analytics and marketing (consent only)

With your consent we measure traffic and advertising effectiveness and show LUMIVIX ads to people who visited the site (Section III). The legal basis is consent (Art. 6(1)(a) GDPR; Section 89(3) of Czech Act No. 127/2005 Coll., on Electronic Communications).

2.5. Server-side conversion sharing with Meta (consent only)

If you consented to marketing cookies, after you submit an inquiry our server sends this event (“Lead”) to Meta Platforms Ireland Limited via the Meta Conversions API. We send: your e-mail address in irreversibly hashed form (SHA-256), the values of the _fbp and _fbc cookies, your IP address and browser user-agent, the event name, time and ID, and the page URL. We do not store the IP address or user-agent ourselves – they are only passed on at the moment of sending.

The purpose is measuring ad effectiveness and de-duplicating the event recorded by the Meta Pixel. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time via “Cookie settings”; without consent nothing is sent. We are joint controllers with Meta for collecting and transmitting this data under Meta’s Controller Addendum; Meta is solely responsible for subsequent processing.

2.6. Legal claims

We may use data to the extent necessary to establish, exercise or defend legal claims (Art. 6(1)(f) GDPR).

2.7.Providing data is voluntary, but without contact details we cannot respond to your inquiry. We do not carry out automated individual decision-making (Art. 22 GDPR).

III. Cookies and measurement tools

3.1.Necessary storage is always used, as the site otherwise cannot remember your choice. Analytics and marketing tools run only after your explicit consent; until then their scripts are not loaded at all. Rejecting is as easy as accepting. Your choice on this site is independent of your choice on lumivix.cz.

3.2.Your choice is stored in your browser with a timestamp and version; we ask again after 12 months or when our tools change. For Google tools we use Google Consent Mode v2 in basic mode (Google’s script loads only after consent).

3.3. Tools overview

  • Analytics – Google Analytics 4: traffic statistics (pages viewed, traffic source, device type, approximate location derived from the IP address, button clicks, form submissions).
  • Marketing – Google Ads: conversion measurement (inquiry submission) and remarketing, i.e. showing LUMIVIX ads in the Google network to people who visited the site.
  • Marketing – Meta Pixel: measuring and targeting ads on Facebook and Instagram, complemented by the server-side conversion sharing under Section 2.5.
  • Marketing – LinkedIn Insight Tag: LinkedIn conversion measurement and ad targeting.
  • Marketing – Pinterest Tag: Pinterest conversion measurement (page visit, inquiry) and ad targeting.

These tools may involve profiling for advertising purposes by the platform operators.

Third-party cookie durations are set by their providers and may change. Fonts are self-hosted; no requests are made to Google Fonts.

How to change or withdraw consent: at any time via “Cookie settings” in the footer or . After withdrawal we delete the measurement cookies and reload the page without these tools. Withdrawal does not affect the lawfulness of prior processing.

Consent record: to be able to demonstrate your consent (Art. 7(1) GDPR), our server stores a record of each choice you make in the cookie banner – a randomly generated consent ID (also kept in your browser), date and time, site, banner version, the chosen categories and how you chose (accept all / reject all / save settings). We do not store your IP address, browser details or anything that directly identifies you. The legal basis is compliance with a legal obligation (Art. 6(1)(c) GDPR). Records are deleted automatically after 3 years.

IV. Retention

  • Inquiries and business correspondence: for the duration of discussions and then 3 years from the last contact, matching the general limitation period (Section 629 of the Czech Civil Code). If a contract is concluded, for its term and the limitation period, and as required by accounting and tax law (typically 5 to 10 years).
  • Inquiry source data: for the same period as the inquiry.
  • Server logs: briefly, per the hosting provider’s settings, typically no more than 30 days.
  • Google Analytics: 14 months from collection. Cookie durations are listed in Section III.
  • Consent records (given, changed or withdrawn): 3 years from creation, then deleted automatically.

After the retention period we delete or irreversibly anonymise the data.

  • Vercel Inc. (USA) – website hosting and server logs; processor.
  • Neon Inc. (USA), via the Vercel platform – inquiry database hosted in an EU data centre (Frankfurt am Main); processor.
