1. Information we collect

• Information you give us: name, email address, phone number, company and message content when you contact us or request a quote.
• Project information: strategy descriptions, code or data files you share for an engagement.
• Automatically collected data: IP address, browser type, device, pages visited and referring URL, collected through server logs and, with consent, analytics and advertising cookies (for example Microsoft Advertising / Microsoft Clarity or similar tools).

2. How we use information

• To respond to inquiries and deliver services you request
• To send invoices and service-related communications

We do not sell or rent your personal information. We share it only with service providers who help us operate (hosting, email, payment processing, analytics) under confidentiality obligations, or when required by law.

4. Advertising and analytics

We may use Microsoft Advertising and similar services to measure ad performance. These providers may use cookies to collect data about your visits. You can opt out of personalized Microsoft advertising at account.microsoft.com/privacy/ad-settings and manage cookies through our cookie banner or your browser.

5. Data retention

We keep inquiry data for up to 24 months and project records for up to 7 years for tax and accounting purposes, unless you ask us to delete them sooner where law allows.

You may request access to, correction of, or deletion of your personal information. California residents have rights under the CCPA/CPRA, including the right to know, delete, correct and opt out of the “sale” or “sharing” of personal information. We do not sell personal information. Visitors from the EEA/UK have rights under the GDPR. Email us to make a request; we respond within 30 days.
