1. What this policy covers

This policy explains what we collect when you use any of our "Services":

The short version: you can play without an account. We use a random ID so votes and progress work. Only if you say yes do we use analytics to see what is fun and what is broken. We do not sell your data, we do not show ads on our own sites, and you can delete your account.

2. Information we collect

2a. When you just visit or play (no account)

DataWhyKept for
A random anonymous ID (a Firebase anonymous account, also stored in a first-party cookie fbuid and in your browser's local storage)Count your vote once, keep your streak and progress, stop spamThe cookie lasts 1 year; the anonymous account until you clear your browser data or ask us to delete it
Game progress, settings, solved puzzlesSave your progressOn your device; copied to our servers only if you sign in
Technical data: IP address, browser and device type, pages requestedDeliver the site, security, rate limits, abuse preventionRaw IP up to 48 hours in rate-limit records; hosting logs for a few days
Your cookie choice (fb-consent)Remember whether you allowed analyticsOn your device

The first time you visit, a banner asks. If you choose Accept (or switch analytics on in Cookie settings), we load:

If you choose Reject, or your browser sends a Global Privacy Control signal and you have not chosen otherwise, none of these load, and the site works exactly the same. Our early-learner math practice page and our teachers page never load analytics, session recording or sign-up prompts, whatever you choose.

2c. When you create an account

You must be 13 or older to create an account, and you confirm that, and that you agree to our Terms and this policy, by ticking a box before the account is made. We record when you ticked it and which version you agreed to. You can sign in with Google or an emailed sign-in link (and, in the app, Apple). We collect:

2d. When you post or take part

2e. Party games

When you join a party game from your phone, the name you type and your in-game inputs pass through our real-time relay to the host screen. The relay does not keep them after the room closes. We keep session statistics (for example how many players and how long a round lasted), not what you typed.

2f. Surviversus and game portals

When you play Surviversus on bossfeed.fun, it sends gameplay statistics to us only if you allowed analytics. Our games published on portals (itch.io, Viverse, CrazyGames, Poki and others) send gameplay statistics to bossfeed.fun: a random per-browser player ID (not your portal account), a session ID, which portal and build, device type, country, and match and performance events. Portal builds respect Global Privacy Control and the in-game "no tracking" setting. The portal itself may also collect data (for example CrazyGames shows ads through its own software on its own site); its privacy policy applies to that.

2g. Emails

2h. Optional widgets

2i. Bots

Our Twitch bot stores the Twitch name and lines of chatters who join a story so the finished story can be shown. Our Discord bot only posts puzzles; it does not collect Discord user data.

Microsoft Clarity session recording, in detail

Clarity is a Microsoft service. It runs only if you allow session recording in Cookie settings (or press Accept all). When it runs, it makes a session replay of the page (what was on screen, clicks, scrolling and taps; anything you type into a form is masked) and builds heatmaps of where people tap, so we can find buttons that confuse people. If you keep clicking the same spot (repeated clicking), that session is tagged as a frustrated click so we can find it.

So we can find one player's recording when they report a bug, your browser tells Clarity your anonymous account identifier; Clarity's script scrambles (hashes) it in your browser before it is sent, and the first 8 characters are sent as a short label. Your email address is never sent to Clarity. It never runs on /account/, on the admin and analytics pages, or on our busiest real-time games.

3. How we use information

To run the Services and save your progress; to show leaderboards, profiles and posts; to send the emails you asked for; to keep the Services safe (spam, cheating, abuse, bots); to understand and improve the games (only with your consent for analytics); to respond to you; and to comply with law. We do not sell your personal information and we do not share it for cross-context behavioural advertising. We do not use your personal information to train AI models.

4. Who we share it with

5. Cookies and similar technology

See our Cookie Policy. Strictly necessary storage is always on; analytics only with consent. Change your choice any time with Cookie settings at the bottom of any page.

7. Your choices and rights

Everyone can:

California residents (CCPA/CPRA) have the right to know what personal information we collect, use and disclose; to access it; to delete it; to correct it; to opt out of the sale or sharing of personal information; to limit the use of sensitive personal information; and not to be discriminated against for exercising these rights.

Visitors from the EU, UK and elsewhere: you have similar rights (access, correction, deletion, portability, objection, withdrawing consent) and may complain to your local data protection authority. Our legal bases are: performance of our Terms (accounts, progress, emails you ask for), consent (analytics, optional emails), and legitimate interests (security, abuse prevention).

8. Children

The Services are for a general audience and are not directed at children under 13. Some puzzles are suitable for younger players and teachers may use them in class, but accounts, posting, uploads and email sign-ups are for people 13 and older, and our early-learner math practice page and teachers page do not load analytics, session recording or sign-up prompts. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has given us personal information, email privacy@bossfeed.fun and we will delete it.

9. Security

We use encrypted connections (HTTPS), access rules on our databases, encrypted storage by our providers, bot checks and rate limits. No system is perfectly secure. We will notify you of a breach affecting your data as the law requires.

10. International users

We are based in the United States and our providers store data in the US and other countries. By using the Services you understand your data will be processed there, with the protections described here.

YouTube videos, Bluesky posts, RSS headlines and links to other sites are governed by those sites' policies. Videos load only when you press play.
