Privacy Policy

BIM•STACK is an independent project. This page explains what information is collected when you use the site and how it's used — in plain language, not legal boilerplate.

What I collect

• Account information. If you sign in with Google or create an account with email/password, I store your name, email address and country (for email/password sign-ups) so you can access features like comparing software.
• Ratings. If you rate a software, that star rating is stored and averaged with other users' ratings for the same product. Ratings aren't linked to your name publicly.
• Contact form. When you send a message through the contact form, your name, email address, the topic you picked and your message are stored in Google Firebase so I can read it and reply. Only I can read these messages — they can't be read back through the site — and they aren't shared with anyone.
• Basic usage. Standard web server logs (like what any static site host keeps) may include your IP address and browser type. This site uses Cloudflare Web Analytics, a privacy-focused, cookie-free analytics tool, to see aggregate traffic like page views and which pages are popular — it doesn't track you individually across sites and doesn't use cookies or fingerprinting. This site also uses Google Analytics (GA4), which does use cookies to recognize repeat visits and understand how people navigate the site — see the Cookies section below for details. I don't run ad-retargeting scripts on this site.
• AI search queries. If you use the "Ask AI" search to describe what you need in your own words, that text is sent to Cloudflare Workers AI, which runs the model on Cloudflare's own infrastructure to pick software from this site's catalog. The text you type is stored for up to 7 days so the same question doesn't have to be re-run, and it's stored on its own — not attached to your name, your account or your IP address. Your IP is used only as a daily counter to stop one visitor exhausting the shared usage limit, and that counter holds no query text. Don't type anything confidential into it; like any search box, it isn't the place for personal or client information.

How it's used

Account data lets you use sign-in-gated features and helps me understand which countries the site's users are coming from, so I know who I'm actually building this for. Aggregate traffic data from Cloudflare Web Analytics and Google Analytics helps me understand which pages and products people find useful. I don't sell your data, and I don't share it with third parties beyond the infrastructure providers below.

Third-party services

This site runs on Google Firebase for authentication and data storage, subject to Google's privacy policy. If you sign in with Google, Google handles that authentication directly. Traffic analytics are handled by Cloudflare Web Analytics and Google Analytics, subject to Cloudflare's and Google's privacy policies. The "Ask AI" search runs on Cloudflare Workers AI — the same Cloudflare privacy policy applies, and what you type there isn't sent to OpenAI, Google or any other AI provider.

Cookies & local storage

The site uses your browser's local storage to keep you signed in between visits. It also uses Google Analytics, which sets a small number of first-party cookies (like _ga and _ga_*) to distinguish repeat visits and measure site usage — these don't identify you by name and aren't used for advertising or cross-site tracking. No third-party advertising or retargeting cookies are used. You can block these cookies in your browser settings, or use a browser extension such as Google's Analytics opt-out add-on, without affecting your ability to use the site.

Your choices

You can sign out at any time from the account menu in the header. To request that your account data be deleted, send me a message and I'll take care of it.
