8Bit.Pizza · Last updated: 19 May 2026

This policy explains how 8Bit.Pizza (a hobby website and app at 8bit.pizza) handles information when you use the pizza dough calculator and related pages. We are based in the United Kingdom and welcome visitors from anywhere in the world.

Who we are

8Bit.Pizza is run as a personal hobby project. For privacy questions or requests, email sliceof@8bit.pizza.

What stays on your device

Most of what you do in the calculator does not get sent to our servers, because we do not run user accounts or store your recipes on a backend:

Dough settings, preferences, and saved recipes in your browser (for example pdc_prefs_v1 in local storage).
Flour library choices (stock, hidden flours, custom entries) in local storage.
Share links that encode your recipe in the URL.
Your cookie choice (accept or reject analytics) in local storage.

You can clear this data anytime via your browser settings. Uninstalling or clearing site data removes it from that device.

What we collect automatically (analytics)

If you click Accept on our cookie banner, we use Google Analytics 4 to understand how the site is used (for example pages viewed, approximate location, device and browser type, and interactions). Google processes this data as our processor. We configure IP anonymisation and do not use analytics for advertising personalisation.

If you click Reject, we do not load Google Analytics. See our Cookie policy for details.

Other third-party services

Google Fonts — pages may request font files from Google when they load. That can involve your IP address being sent to Google.
Hosting — our host may log standard technical data (IP address, user agent, time of request) when you download pages and files. We use these logs only for security and operation.

Service worker and offline use

The site may register a service worker to cache files so the app works offline or loads faster. That is functional storage, not used to profile you.

When you email us

If you contact us at sliceof@8bit.pizza, we use your email address and message content only to respond. We do not sell your email address.

Optional support

Optional support is offered on our About page. On the website, support goes through Ko-fi. In the Android app, optional support goes through Google Play consumable in-app products (for example supporter_coin_1, supporter_coin_3, and supporter_coin_5). These purchases do not unlock extra features. Payment details are handled by Ko-fi or Google — we only receive what they pass to us (such as amount and, if you provide it, name or email). Ko-fi’s and Google’s own privacy policies apply to those checkouts.

Why we use your data (UK lawful bases)

Consent — analytics cookies, when you accept them.
Legitimate interests — running and securing the site, replying to email, and understanding aggregate use of a free tool.
Contract — if you email us and we reply, to perform that request.

How long we keep data

Analytics: according to Google Analytics settings (typically months, not forever).
Email: until the conversation is finished, unless we need to keep a record for a legal reason.
On your device: until you clear browser storage or we change what we store (we will try to note major changes here).

International transfers

Google and other providers may process data outside the UK. Where required, they rely on appropriate safeguards (such as standard contractual clauses).

Your rights

Under UK data protection law you may have rights to access, correct, erase, restrict, or object to processing, and to data portability where applicable. You can also complain to the Information Commissioner’s Office (ICO). To exercise your rights, email sliceof@8bit.pizza.

Children

The calculator is a general audience tool. It is not directed at children under 13, and we do not knowingly collect personal data from them.

Changes

We may update this policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the site after changes means you accept the updated policy.
