Privacy Policy

Home Theater Builder is a free tool for planning a compatible home theater system. This page explains, plainly, what data the site collects, why, and what you control. There is no account system, no sign-up, and no email collection anywhere on the site.

What we collect

Three things, and nothing else:

• One cookie, to remember your saved builds. When you save a build, we set a single cookie (htb_uid) containing a random, unguessable id, not your name, email, or any identifying information. It has no purpose beyond letting you find and delete your own saved builds later without an account. It is not used for advertising, and it is not shared with any ad network or tracker.
• Local storage, for your in-progress build.While you are using the builder, your current part selections are kept in your browser’s local storage so the page survives a refresh. This never leaves your device unless you click Save or Share.
• Anonymous, aggregated usage analytics. We use Vercel Web Analytics, which does not use cookies and does not identify individual visitors. It counts things like which pages and product categories get visited, whether a search returned results (never the words you searched), and which outbound retailer links get clicked, so we know which parts of the site are useful. Vercel discards the underlying visitor signal within 24 hours. We never see your IP address, name, or any personal identifier through this system.

Saved builds

A saved build stores the name you gave it, the parts you selected, and a price snapshot, all attached to the random cookie id above, never to a real identity. You can delete any saved build at any time from the Saved page. Clearing your cookies has the same effect: the old builds become unreachable, since nothing ties them to you except that cookie.

Outbound retailer links and affiliate disclosure

Buy links on this site go to retailers’ own websites. Some of these are affiliate links: if you buy something after clicking through, we may earn a commission at no extra cost to you. This never affects which products we show, how we rank them, or what our compatibility checks say, those come from the stored spec data alone. When we click through to a retailer, that retailer’s own site handles the transaction and is governed by their own privacy policy, not ours. If we join an affiliate network in the future, that network may itself process click data for commission tracking; we will update this page to name it if so.

Who processes data on our behalf

The site is hosted on Vercel (hosting, content delivery, and the analytics described above) with its catalog stored on Supabase (a managed Postgres database). Both process standard web request data (like IP addresses, as part of ordinary internet routing and abuse prevention) as our infrastructure providers. Neither uses site data for their own advertising.

Children’s privacy

This site is not directed at children under 13, and we do not knowingly collect personal information from anyone in that age group.

Your choices

• Clear your cookies or local storage at any time through your browser settings to reset your anonymous id and locally stored build.
• Delete any saved build directly from the Saved page.
• Email support@hometheaterbuilds.com with any question about your data, including a request to confirm or delete a specific build.

We do not honor browser “Do Not Track” signals differently from any other visit, since the site collects no cross-site tracking data for DNT to meaningfully change.

Changes to this policy

If what the site collects changes, this page changes with it and the date at the top updates. We do not expect to add account sign-up, email capture, or advertising trackers without saying so here first.
