Privacy Policy

Last updated: October 30, 2026

OPBoostBuilds ("we", "us", "our") is a fan-made gaming builds resource. This policy explains exactly what data we collect, why we collect it, and how it is stored. The site shows ads served by Mediavine, covered in the advertising section below. Outside of advertising, we do not sell your data or share it with third parties for marketing purposes.

Data Stored on Your Device

We use your browser's localStorage to save your build progress (acquired items) and UI preferences locally. This data stays on your device and is never sent to our servers unless you sign in.

Data We Collect When You Sign In

Creating an account is optional. If you sign in via Supabase authentication, we store the following in our database:

  • Your email address or OAuth identifier (e.g. Google, Discord)
  • Display name and avatar URL (if provided via OAuth)
  • Builds you have liked or favorited
  • Your pet collection and active pet preference

All account data is stored in Supabase and protected by Row Level Security. Only you can read or modify your own records.

Contact Form

If you submit a message via our contact page, we store your name, email address, subject, category, and message in our Supabase database. We use this information solely to respond to your inquiry and do not use it for marketing.

Third-Party Services

We use the following services to operate the site. Each has its own privacy policy governing their data practices:

  • Supabase: authentication and database (privacy policy)
  • Cloudflare Pages & R2: website hosting, CDN, image storage, and privacy-first web analytics. Cloudflare Web Analytics is cookieless and does not track individual users or build behavioral profiles (privacy policy)
  • Google Analytics: measures how the site is used, including which pages you visit and how long you stay. Google Analytics sets first-party cookies and assigns your browser an anonymous identifier so repeat visits can be recognized. We use it to understand which builds and guides people find useful. We do not sell this data or use it for advertising (privacy policy)
  • Mixpanel: product analytics and session replay. Records which builds and guides you open, which creator videos you click through to, and what you like or favorite, so we know what to keep updated. It also records a replay of your visit: the pages you move through, where you scroll, and what you click, so we can see where the site is confusing to use. Anything you type into a form is masked and never recorded. Mixpanel stores an identifier in your browser to link those actions into a single visit, and if you are signed in it is linked to your account id so your activity is consistent across devices. We do not sell this data or use it for advertising (privacy policy)
  • YouTube: embedded build guide videos. Google's privacy policy applies when you play a video (privacy policy)
  • wsrv.nl: open-source image proxy used to optimize third-party images

Cookies

The only cookies we set without asking are the ones that keep you signed in, via Supabase. Those are required for your account to work.

How analytics behaves depends on where you are. If you are visiting from the EU, EEA, UK, Switzerland, California or Quebec, we ask first: Google Analytics and Mixpanel stay switched off until you accept in the banner shown on your first visit. Decline and neither one loads, no request is made to them, and no analytics cookie is set. Everywhere else they run by default, and you can still turn them off with a content blocker or by blocking cookies. If we cannot tell where you are, we ask.

When analytics is running, Google Analytics sets first-party cookies recording which pages you view and how long you spend on them, and Mixpanel stores an identifier in your browser's local storage and records a replay of your visit. Form fields are masked in those replays, so what you type is never captured. We do not share this analytics data with advertisers. Advertising cookies are covered separately below.

Cloudflare Web Analytics runs either way. It is cookieless by design, assigns you no identifier, and builds no profile of you.

To change your answer, clear this site's local storage and the banner will ask again. You can also block analytics through your browser settings or a content blocker. Signing in and browsing builds work normally either way.

Advertising

Mediavine Programmatic Advertising (Ver 1.1)

The Website works with Mediavine to manage third-party interest-based advertising appearing on the Website. Mediavine serves content and advertisements when you visit the Website, which may use first and third-party cookies. A cookie is a small text file which is sent to your computer or mobile device (referred to in this policy as a "device") by the web server so that a website can remember some information about your browsing activity on the Website.

First party cookies are created by the website that you are visiting. A third-party cookie is frequently used in behavioral advertising and analytics and is created by a domain other than the website you are visiting. Third-party cookies, tags, pixels, beacons and other similar technologies (collectively, "Tags") may be placed on the Website to monitor interaction with advertising content and to target and optimize advertising. Each internet browser has functionality so that you can block both first and third-party cookies and clear your browser's cache. The "help" feature of the menu bar on most browsers will tell you how to stop accepting new cookies, how to receive notification of new cookies, how to disable existing cookies and how to clear your browser's cache. For more information about cookies and how to disable them, you can consult the information at All About Cookies.

Without cookies you may not be able to take full advantage of the Website content and features. Please note that rejecting cookies does not mean that you will no longer see ads when you visit our Site. In the event you opt-out, you will still see non-personalized advertisements on the Website.

The Website collects the following data using a cookie when serving personalized ads:

  • IP Address
  • Operating System type
  • Operating System version
  • Device Type
  • Language of the website
  • Web browser type
  • Email (in hashed form)

Mediavine Partners (companies listed below with whom Mediavine shares data) may also use this data to link to other end user information the partner has independently collected to deliver targeted advertisements. Mediavine Partners may also separately collect data about end users from other sources, such as advertising IDs or pixels, and link that data to data collected from Mediavine publishers in order to provide interest-based advertising across your online experience, including devices, browsers and apps. This data includes usage data, cookie information, device information, information about interactions between users and advertisements and websites, geolocation data, traffic data, and information about a visitor's referral source to a particular website. Mediavine Partners may also create unique IDs to create audience segments, which are used to provide targeted advertising.

If you would like more information about this practice and to know your choices to opt-in or opt-out of this data collection, please visit National Advertising Initiative opt out page. You may also visit Digital Advertising Alliance website and Network Advertising Initiative website to learn more information about interest-based advertising. You may download the AppChoices app at Digital Advertising Alliance's AppChoices app to opt out in connection with mobile apps, or use the platform controls on your mobile device to opt out.
