Cookie Policy
Last updated 13 October 2026
This page lists what this site stores in your browser and why. We keep it short because the site itself is deliberately light on tracking.
AI conversations and advertising choices
The website assistant processes voice through OpenAI or Google, and typed messages through Anthropic or OpenRouter and its selected model provider. You choose when to start a voice conversation and can use text instead. We do not record raw audio. Conversations are processed to answer you; server-side chat context is cleared after the session unless you separately consent to saving it. Consented transcripts are retained for up to 30 days. Confirmed enquiry details are retained for business follow-up, independently of transcript consent.
Opening the assistant sets a necessary zt_assistant_visitor cookie for up to 90 days to protect the free allowance against repeated use. It contains a random signed identifier, not contact details. Usage checks store request timestamps and keyed hashes of this identifier and your network address. The allowance uses a rolling 24-hour window, shared across AI providers; visitors on the same network may share the limit. Expired usage records are removed during later allowance reservations. This security data is not used for advertising. WhatsApp and enquiry forms remain available after the allowance is used.
Optional analytics and advertising cookies remain disabled until you choose them. Advertising consent permits Meta Pixel and server-side Conversions API events, including hashed contact details for saved enquiries and confirmed payments linked to those enquiries, with permitted campaign/cookie identifiers. Payment events include the amount, currency and payment time, never bank or card credentials. Consented enquiry matching data is retained for up to 90 days. WhatsApp clicks measure a click, not a conversation or a sale. Conversation text is not sent to advertising platforms. You can change these choices using Privacy on any page; withdrawal stops future optional tracking and cancels queued events linked to enquiries from your current browser session. Events already delivered cannot be recalled. Contact us to withdraw consent for enquiries from another session.
Promotion preferences store only a campaign identifier and last-shown time in your browser so that popups respect their frequency limit. Optional promotion analytics follow your analytics and advertising choices.
Contact zarachtech@gmail.com to request access to or deletion of enquiry information. Provider processing may involve transfers outside Nigeria; their own privacy terms also apply.
Strictly necessary
These are required for the site to work and cannot be switched off.

The session cookie is marked HttpOnly, SameSite=Lax and, over HTTPS, Secure. It contains an identifier only — no personal data.
Analytics
Where Google Analytics 4 is enabled, it sets cookies (typically _ga and _ga_<id>) to distinguish visitors and measure how pages are used. These last up to two years. We use analytics only in aggregate — to see which pages are useful — never to identify you individually.
You can opt out for every site you visit with Google's browser add-on, or block the cookies as described below.
Spam protection
Where Google reCAPTCHA is enabled on the contact form, Google sets cookies and collects device and interaction signals to tell humans from bots. This is loaded only on pages carrying the form. Google's handling of that data is governed by its own privacy policy.
What we do not do
With advertising consent, Meta Pixel uses advertising cookies such as _fbp and _fbc to measure campaign results. Server conversion events complement browser events and share an event ID to avoid counting a saved enquiry twice. You can reject optional cookies or change your choices using Privacy on this website.
Controlling cookies
Every major browser lets you see, block and delete cookies, usually under Settings → Privacy. Blocking strictly necessary cookies will stop the contact and newsletter forms from working, because the anti-forgery check depends on the session.
