Privacy policy
Last updated 30 October 2026
- You can play without an account and without telling us anything about you.
- An account only needs an email and a password. Other players never see your email.
- We count visits with Google Analytics and show ads from Google. In Europe, ads are only personalized if you say yes; elsewhere you can turn that off. Ads are never personalized for children.
- We never sell your data for money.
- You can delete your account and everything saved with it at any time, from the Me page (Stats).
Who we are
Blob Empire is a free browser game made by Eliot Dupouy, who is responsible for your data (the "data controller"). In this policy, "we" means Eliot Dupouy.
Questions, or want to use your rights? Email eliotdupouy99@gmail.com. We answer within one month.
What we collect, why, and for how long
| What | Why | Legal reason | How long |
|---|---|---|---|
| Progress on your device | Your level, coins, items and settings are saved in your browser so you can carry on next time. | Needed to run the game you asked for. | Until you clear your browser data. |
| Account | Your email, your password (stored scrambled, we can't read it), your player name and a copy of your progress, so you can play on any device. Your email is only used to sign you in and to send a link if you forget your password. | Needed to give you the account you asked for. | Until you delete the account. |
| Online matches | Your player name, your moves and a random seat code go through our match server so the other players in your match can see them. | Needed to run the match you joined. | Deleted when the match ends. Your own results stay in your progress. |
| Technical logs | Like every website, our hosts see your IP address and browser type when you load the game, to deliver it and keep it safe from attacks. | Our legitimate interest in a working, safe game. | A few days. |
| Google Analytics | How many people play, on what kind of device, from which country, and how games go (a game was started or finished). It doesn't tell us who you are, and Google Analytics doesn't keep IP addresses. Unless we know you are under 13, it can also use Google signals (for players signed in to Google who allow ad personalization) and help Google pick better ads, as described in "Ads". | Your consent in the EU, UK and Switzerland. Elsewhere, our legitimate interest in improving the game. | 2 months. |
| Ads | See "Ads" below. | Your consent in the EU, UK and Switzerland. Elsewhere, our legitimate interest in keeping the game free, and you can opt out of personalized ads. | Set by Google (see below). |
We don't collect real names, addresses, phone numbers, photos or your exact location, and we don't use your data to make automated decisions about you.
Ads
Ads keep Blob Empire free. They come from Google AdSense. Google can use cookies to show ads based on your interests and other sites you visit ("personalized ads"), to limit how often you see the same ad, and to stop fraud. For personalized ads, Google is responsible for its own use of the data.
- In the EU, UK and Switzerland, ads are only personalized if you say yes in the consent message.
- Elsewhere, ads can be personalized. You can turn this off at any time in Google's ad settings, and in US states with privacy laws through the "Do not sell or share" choice in our privacy message.
- Children: when we know a player is under 13, ads are never personalized, and we tell Google so it only shows ads suitable for children.
How Google uses data from sites like ours: policies.google.com/technologies/partner-sites.
Cookies and storage on your device
- Ours, always on (needed for the game to work): your progress (and, while you're signed in, the guest progress you had before, so you get it back when you sign out), your sound setting, which updates you've read, whether you're signed in, the year you were born if we asked it (United States only), and your seat in an online match. They stay in your browser and aren't used to track you.
- Google Analytics (
_gacookies): tell visits apart so we can count players. Kept up to 2 years by your browser unless you clear them. - Ad blocker check: on blobempire.com, the game checks whether an ad blocker is on, because ads keep it free. Nothing is stored or sent: if one is on, we just ask you to pause it before playing.
- Google ads: show personalized ads (only as described in "Ads" above), limit how often you see an ad, and stop fraud. See policies.google.com/technologies/cookies.
In the EU, UK and Switzerland, Google Analytics and ads don't put anything on your device until you say yes in the consent message, and you can change your answer at any time. Until you say yes, Google may only receive basic signals without cookies (for example, that a page was opened), which don't identify you.
Who handles your data for us
We use these companies to run the game. They only use your data to provide their service to us:
- Vercel: hosts the website.
- Supabase: stores accounts and saved progress.
- Cloudflare: runs the online match server.
- Google: Analytics and ads. Google's privacy policy.
- An email delivery service that sends sign-in and password emails.
Some of these companies are in the United States. When your data leaves the EU or UK, it is protected by the EU–US Data Privacy Framework or by the European Commission's standard contractual clauses.
We never sell or rent your data for money. Under some US state laws, letting Google show personalized ads can count as "selling" or "sharing" data: you can opt out as described in "Ads" above.
Children
Blob Empire is a game for all ages, played by adults and children. Children can play without an account and without giving us any personal information.
Making an account needs an email. In the United States, we first ask the year you were born, and accounts are only for players 13 and over: younger players keep playing as guests, so we collect nothing about them. We keep the answer only on your device, so it can't simply be changed and tried again.
Everywhere else: if you are under 13, or under the age of digital consent in your country (16 in many EU countries), please ask a parent or guardian before making an account. If we learn that an account belongs to a child without a parent's agreement, we delete it. Parents can email us at any time to see or delete their child's data.
Your rights
Wherever you live, you can ask us to:
- show you the data we hold about you, or send you a copy;
- correct it;
- delete it (you can also delete your account yourself: Me → Stats → Delete account);
- stop or limit using it, or object to how we use it;
- withdraw your consent at any time, through the consent message or by clearing your browser data.
Email eliotdupouy99@gmail.com. If you live in the EU, UK or Switzerland and aren't happy with our answer, you can complain to your country's data protection authority. In the United States, residents of some states (such as California) have the same rights, including opting out of personalized ads, and we won't treat you differently for using them.
Keeping your data safe
Connections to the game are encrypted (HTTPS). Passwords are stored scrambled. Each account can only read its own saved data.
Changes
If we change this policy, we'll update the date at the top. Big changes will also show in the game's "What's new".
