Privacy Policy

1. Who is the data controller

The data controller for this website is Delacroix Sp. z o.o., ul. Lawendowa 1, Zarzyce Małe, 34-142 Leńcze, Poland, NIP: 5512681365, KRS: 0001274928, registered with the District Court for Kraków-Śródmieście in Kraków, 12th Commercial Division of the National Court Register.

Contact for any privacy question or request: the chat on https://sellchat.eu (bottom-right corner of every page) — leave your e-mail address in the chat and we reply by e-mail.

2. What data we process, and why

We collect different data depending on how you interact with the site:

• Buying SellChat: when you click “Order” you are taken to a Stripe-hosted checkout page. Stripe collects your email, name, and payment details directly — we never see or store your card number. After a successful payment, Stripe sends us your email address, name, and the completed transaction so we can deliver your package and issue any legally required accounting records.
• Download & confirmation email: once payment is confirmed, we use MailerSend (a transactional email provider) to send your download link to the email address Stripe passed us. MailerSend processes your email address and name on our behalf for this single purpose.
• The live demo chat widget on this site: if you type a message into the chat bubble on sellchat.eu, that message is sent to an AI provider (Anthropic's Claude) to generate a reply, temporarily stored in our Upstash Redis database so the conversation has context, and — if the conversation looks like a sales lead, or you submit the contact form in the chat — sent as a Telegram alert to us and logged through our Make.com automation to a Google Sheet, so we can follow up. Chat transcripts are kept for 7 days and contact details for 30 days. Do not share sensitive personal data (health, financial account numbers, etc.) in the chat widget.
• Contacting us through the chat (for the installation service, a refund, a complaint or a privacy request): we use the messages and the e-mail address you leave in the chat to handle your request and reply by e-mail. Where a request needs that correspondence kept longer than the chat retention above (for example a refund or a complaint), we keep it for as long as handling the request and any related claims requires.
• Site analytics: we use Vercel Analytics, a cookie-free, privacy-preserving analytics tool. It records aggregated page-view and click events (e.g. which “Order” button was used) without using cookies, without a persistent identifier, and without being able to identify you personally.

3. Legal basis for processing

• Performance of a contract (Art. 6(1)(b) RODO): processing your order, delivering the package, sending the confirmation email.
• Legitimate interest (Art. 6(1)(f) RODO): operating the demo chat widget, following up with visitors who show buying intent, and keeping aggregated, non-identifying analytics to improve the site.
• Legal obligation (Art. 6(1)(c) RODO): keeping transaction records for the periods required by Polish tax law.

4. Who receives your data (processors / recipients)

We use the following service providers to run this site and deliver SellChat. Each acts as our data processor (or, for Stripe's own compliance obligations, as an independent controller for payment-related legal duties) and is only given the data it needs for its specific task:

• Stripe, Inc. — payment processing (card data never touches our servers).
• MailerSend — transactional email delivery (download link, order confirmation).
• Anthropic — processes the text you send to the demo chat widget to generate a reply.
• Upstash — short-term storage of chat sessions (Redis database).
• Make.com — automation that forwards demo-chat leads to Google Sheets and Telegram.
• Google (Google Sheets) — lead log for the demo chat widget.
• Telegram — instant alert to us when the demo chat widget flags a hot lead.
• Vercel Inc. — website hosting, server logs, and cookie-free analytics.

5. International data transfers

Some of the providers above (including Stripe, MailerSend, Anthropic, Upstash, Google, Telegram, and Vercel) may process data outside the European Economic Area, in particular in the United States. Where that happens, we rely on the safeguards those providers offer (such as the EU-U.S. Data Privacy Framework or Standard Contractual Clauses).

6. How long we keep your data

• Transaction and invoicing data: kept for the period required by Polish tax law (generally 5 years from the end of the tax year in which the transaction occurred — confirm the exact period with your accountant).
• Demo chat conversations: kept only as long as needed to provide the conversation and follow up with genuine leads, then deleted or anonymized on a rolling basis.
• Email correspondence: kept as long as needed to resolve your query, then deleted or archived per our retention practice.

7. Your rights

Under RODO/GDPR, you have the right to: access your data, request correction or erasure, restrict or object to processing, request data portability, and withdraw consent at any time where processing is based on consent. You also have the right to lodge a complaint with the Polish data protection authority (Prezes Urzędu Ochrony Danych Osobowych, UODO) or your own country's supervisory authority.

To exercise any of these rights, write to us via the chat on https://sellchat.eu (bottom-right corner of every page) — leave your e-mail address in the chat and we reply by e-mail.

8. Cookies

As of the date above, this site does not set any cookies that require your consent. Vercel Analytics is cookie-free by design. If we add any cookie-based tool in the future (e.g. marketing or session cookies), we will update this policy and the cookie banner on the site will ask for your consent before those cookies are set.

9. Security

We use providers (Stripe, Vercel, Upstash, MailerSend) that maintain their own industry-standard security certifications. We do not store payment card data ourselves. Access to any data we do hold is limited to what's needed to run the site and fulfil orders.

10. Changes to this policy

We may update this Privacy Policy from time to time. The “last updated” date at the top will always reflect the current version. Material changes will be reflected here before they take effect.

11. Contact
