How we handle your data.

Contact form submissions: when a visitor submits the contact form at interrupt.llc/#contact, we receive the four form fields (name, email, phone, message) plus an ALTCHA proof-of-work token. We store the submission only in the Gmail inbox of uplink@interrupt.llc via Gmail API delivery. No other database, no third-party CRM, no marketing-automation platform. The form uses ALTCHA (MIT-licensed, self-hosted HMAC-signed proof-of-work captcha) to prevent automated spam; ALTCHA does not share data with third parties.

Analytics: we use Google Analytics 4 for aggregate pageview and session analytics on the marketing site. GA4 collects standard measurements — page path, referrer, device category, approximate geographic region (country/region level), session duration — per Google's published GA4 documentation. No personally identifying information is passed to GA4. IP addresses are anonymized per GA4 default. A visitor can opt out via browser-level controls or the Google Analytics opt-out browser add-on.

Server logs: the site is hosted on Cloudflare Workers. Cloudflare generates standard request logs (request URL, response status, client IP, user agent, timestamp) retained per Cloudflare's published retention policy. These logs are used for security monitoring and infrastructure debugging. We do not export Cloudflare logs to third parties.

Contact form submissions are used solely to respond to the inquiry and conduct an engagement scoping conversation. Engaged clients' contact information is retained in the relevant email thread and (if the client becomes a signed client) in the engagement agreement and invoicing systems. We do not enroll inquiry-submitters in marketing email sequences. No unsolicited outreach.

Analytics data is used to understand aggregate site traffic patterns and inform content strategy. Specific sessions are not individually reviewed; GA4 data is analyzed at aggregate level only. Server logs are used for security and debugging only, not for user profiling.
