Privacy Policy

1. Data controller

RealStack Agency ("RealStack"), operator of realstack.agency, is responsible for processing personal data you provide when contacting us via WhatsApp, visiting our website, or hiring our web development services.

2. Data we collect

We may collect: name, phone number, email, information about your project or business, billing data required to process payments, and advertising campaign parameters (UTM) when you arrive from Meta, Google or TikTok ads. If you share other people's contact cards via WhatsApp, that third-party data is minimized (contact caps, truncation) and reduced to partial digits after a short window. Our WhatsApp commercial assistant may use automated rules and, only when needed to finish qualification, an AI provider with a minimized message excerpt (no full phone number). You can ask for a human advisor by typing «asesor». We do not intentionally collect sensitive data.

3. Purpose of processing

We use your data to: respond to commercial inquiries via WhatsApp, prepare proposals and contracts, execute web development projects, process payments through authorized gateways (Bre-b, Bancolombia, and Mercado Pago), send project-related communications, and improve our services and advertising campaigns.

4. Legal basis

Processing is based on your consent when contacting us, performance of a service contract, compliance with legal obligations, and our legitimate interest in operating and improving the business.

5. Data sharing

We may share data with technology providers necessary to deliver the service (AWS hosting, payment gateways, domain registrars, email services). We do not sell or rent your personal data to third parties for advertising purposes.

6. Cookies and similar technologies

This site may use browser local storage (localStorage, sessionStorage) for language preferences and UTM campaign parameters. We do not use invasive tracking cookies without your knowledge. Ad platforms (Meta, Google) may apply their own policies when you interact with our ads.

7. Retention

We retain your data while an active commercial relationship exists and for legally required periods for tax, accounting and warranty obligations. WhatsApp messages are purged per our ops matrix; third-party shared contacts are minimized and scrubbed sooner than the full thread history.

8. Your rights

You may request access, rectification, updating, deletion or objection to processing by contacting us on WhatsApp at +57 323 595 4237. We will respond within applicable legal timeframes in your jurisdiction.

9. Security

We implement reasonable technical and organizational measures to protect your information. No Internet system is 100% secure; we recommend not sharing passwords or sensitive financial data over unencrypted channels.

10. Changes

We may update this policy. The date of the last revision will be shown at the top of the document. Continued use of the site implies acceptance of published changes.
