Privacy Policy

Last updated: 9 November 2026. This policy describes what Glowsum (the web game at glowsum.embergaming.studio) does today.

Who we are

Ember Gaming LLC ("we"). Contact: support@embergaming.studio.

What stays on your device

Your progress, settings and pencil marks are saved in your browser's storage on this device. A random player id is created there; it is not linked to your name or email.

What we collect

Daily and Weekly Challenges. When you play them we store your random player id, the leaderboard name you choose, whether you solved the puzzle and your time. Your name and time appear on the public leaderboards. Names with offensive words are replaced with "Player".

Gameplay statistics (only if you agree). On your first visit we ask whether you want to share anonymous gameplay statistics. Only if you choose Yes, the game sends short events with your random player id: puzzle opened or solved, mistakes and hints used, time taken, and settings you changed. They contain no name, email or location. They are stored in our own database and, for analysis, in PostHog (US), with automatic tracking, session recording and personal profiles switched off. You can change your choice in Settings at any time; switching it off stops both.

Crash reports. When the game or our server hits an error, a report goes to Sentry (US): the error, where in the code it happened, the browser and page. No player id, name, IP address or link details are included. We use them only to fix bugs.

Sign-in (optional). If you sign in with Google or Apple to save your progress across devices, we receive the account id they give the game and your first name, never your password or email inbox. If you sign in with an email code, we use your address only to send the code and store only a one-way hash of it. We store your Ember ID, your username and a copy of your game progress.

Levels you share. If you share a level from the editor, we store it with your leaderboard name, and other players can play, like and report it.

Feedback. If you send feedback, we store your message with your random player id, the level you were on and your language.

Server logs. Our hosting provider (Cloudflare) processes your IP address to deliver the site and protect it from abuse. We do not store IP addresses in our database.

What we do not do

The web game has no ads, no advertising ids, no tracking cookies and no real-money purchases (the shop is a free test mode). We do not sell your data.

Why we use it

To run the game and its leaderboards, keep your progress, stop cheating and abuse, and (with your consent) learn which levels are too hard so we can improve them.

Who we share it with

Cloudflare (hosting and database), Sentry (crash reports), PostHog (gameplay statistics, only if you agreed) and Google and Apple (only when you choose to sign in with them). Nobody else.

How long we keep it

Account data and saves: until you delete your account. Leaderboard results and gameplay statistics: up to 24 months, then they are deleted or kept only as totals.

Your choices and rights

Turn gameplay statistics off in Settings. Delete your account and its saved progress in Settings or on the Delete account page. Clearing your browser's site data removes everything stored on your device. Depending on where you live you may also have rights to access, correct or object to the use of your data; write to us and we will help.

Children

Glowsum is meant for players aged 13 and older. We do not knowingly collect data from younger children; if we learn that we have, we will delete it.

Security

Data travels over HTTPS. Sign-in tokens are checked by our server on every request.

International transfers

Cloudflare, Sentry, PostHog and Google may process data in the United States and other countries, under their own data protection terms.

Changes

We will post changes here and update the date above.
