Cookie Policy

This Cookie Policy explains how BrewIQ uses cookies and similar storage technologies on the brew-iq.app website and in the mobile app. Read alongside the Privacy Policy, which explains the wider picture of how we handle your data.

What’s a cookie, and what else counts?

A cookie is a small text file a website saves on your device so it can remember you between visits. Similar technologies include the browser’s localStorage and sessionStorage, mobile device-local storage (used by the Supabase client and Zustand persistence), and any fingerprinting-style techniques we explicitly exclude. This policy covers all of them.

What we currently use

Strictly necessary (always on)

• Authentication — the app uses secure local storage to keep you signed in. Without this the app can’t function. On the web, this is handled by Supabase Auth cookies and localStorage entries; in the mobile app, by secure device storage.
• Session and preferences — small settings like which brewing method you last used, so the app opens where you left off.
• Security — tokens to prevent CSRF, replay, and automated abuse.

Functional

• Display band — the marketing site shifts its palette based on time of day. This is computed from your device clock, not stored, but some preference overrides may be saved locally in future.
• Font delivery — the marketing site uses the Fraunces typeface, which we self-host via Next.js. No third-party font request is made from your browser, so no third party (including Google) receives your IP address when the page loads.

Analytics and performance (planned)

As described in the Privacy Policy, we plan to introduce product analytics to understand which parts of BrewIQ get used, what breaks, and where people drop off. When we do:

• We will add the specific cookies and local-storage keys to this page.
• On the website, if local law requires consent for analytics cookies (for UK and EEA visitors, it typically does), we will ask for it via a banner before any non-essential cookie is set.
• In the mobile app, analytics run through the vendor’s SDK rather than cookies, and are tied to your BrewIQ account identifier — not a third-party advertising ID.

What we don’t set

• Third-party advertising cookies.
• Cross-site tracking pixels or remarketing tags.
• Fingerprinting libraries designed to identify you without consent.

Managing cookies

You can clear cookies and local storage at any time from your browser settings (“Clear site data” or similar) or, on mobile, by signing out and reinstalling the app. Blocking strictly-necessary cookies will log you out and stop the app functioning. Most browsers also let you deny all non-essential cookies by default.

For the website, once we launch a consent banner you can revisit your choice at any time from the footer link that will appear then. Until that banner is live, the site only uses the strictly-necessary and functional items listed above.

Changes

We’ll update this page whenever we add, remove, or change a cookie or a similar storage mechanism. The date at the top tells you when it last changed.
