Privacy policy

Version of November 12, 2026

Who is responsible

The company responsible for your data on Bitrir (the data controller) is Centro Publicidad Electrónica España SL, with its registered address at C/ País Valencià, 3, 03610 Petrer (Alicante), Spain, and Spanish tax ID (NIF/CIF) ESB53449120. For any questions about your data, email us at hola@bitrir.com.

What Bitrir is

Bitrir is a free platform for games made by the community: you can play, challenge your friends and make your own games with artificial intelligence. You can play without an account. We don't show third-party ads or use analytics or advertising tools from other companies. We may recommend our own games and apps, without building advertising profiles.

If you play without an account

To count visits and how long each game is played, the website uses a random number that only lives in the page's memory: it isn't saved in your browser and it's lost when you close or reload the page, so we can't tell whether you'd been here before.
For each visit we keep the day, the first page you opened, the link you came from (for example, a Bitrir link on a social network or the website that linked you here) and the country, which we work out from your browser's time zone. We don't store your IP address with that data.
To stop abuse, we count for a short while the requests that come from each IP address, without storing it.
If you report a game without an account, we keep the reason and whatever you write, without knowing who you are, and we delete it after 90 days.
The stats and saved games of a game played without an account stay on your device. Achievements without an account last as long as your visit.
Granjeros remembers on this device when a trailer in “More games” was last opened and which one it was, to rotate them and limit how often they appear. It doesn't use your account data to choose them.

If you have an account

Accounts are Videolibros accounts and also work on Pixelbook. Your email and your password are stored by Videolibros under its privacy policy; Bitrir only receives a number that identifies your account.

If you sign in with Google, Google gives Videolibros your email address, if it's verified, and an identifier for your Google account. Videolibros uses them only to find or create your account; it doesn't store your Google name or photo, and Bitrir only receives your account number. The Google button only loads on the screens for signing in, creating your account and deleting it: when it loads, Google receives your IP address and handles that data under its privacy policy.

Bitrir stores:

Your username, your friend code, the month and year you were born (not the day), when you signed up and when you last signed in. We use the month and year to work out your age at any given time. If you told us your age before we asked this way, we store instead the month and year that follow from that age and from when you told us.
Your profile picture, if you upload one. A member of the team reviews it before others can see it.
Whether or not you want to appear in the rankings, and who can see your profile.
The language your notifications and emails are sent in (Spanish or English): the one of the website where you created your profile, or the one you choose later.

What we keep when you play

Achievements, stats and cloud saves for each game.
Scores and records. In some games, also the replay of your best run (the “ghost”), so others can compete against it.
Your Elo score in the games that use it, your playtime per day and per game, your ratings and your favorites.
In persistent worlds, your character, your items and their history, to settle disputes and deal with cheating.

Friends and online play

We keep your friendships, requests, invitations and challenges. Your friends can see whether you're online and what you're playing.
Your public profile shows your username, your approved photo, your achievements and your place in the rankings. You can hide yourself from the rankings in Settings.
In quick matches with people you don't know there's no chat, and minors play with minors and adults with adults, based on your age, worked out from the month and year you were born.
If you report someone or a game, we keep who reported, who or which game was reported, the reason, what you tell us and, in drawing games, the reported drawing. The drawing is deleted as soon as the team resolves the report. We also keep blocks and penalties.

Notifications

Bitrir's bell keeps your notifications. Read ones are deleted after 90 days.
Emails about the games you make are sent by Videolibros, since it's the one that knows your address. In Settings you choose which ones you want to get.
If you turn on notifications on your device, we store the subscription address your browser gives us or, in the app, your phone's notification ID, from the Google, Apple, Mozilla or Microsoft notification service, and your device's time zone, so we don't notify you at night. You can turn them off whenever you want, in Settings or in your phone's settings.

If you make games

We keep your projects: the game files, their versions, the release notes, the reports from the automatic checks and what the review decides. When a game is published, it appears with your username and its code can be downloaded.
You can create without an account: the project stays anonymous, with a code to claim it with your account. If no one claims it within 30 days, it's deleted.
The tokens you give your AI agent are stored in a way that no one can read them, and you can revoke them in your profile.
What you write to your AI (ChatGPT, Gemini, Claude or another one) is handled by the company behind that AI under its own privacy policy. If you use an AI connected to Bitrir, like the Bitrir app in ChatGPT, Bitrir only receives the game files and what's needed to make the game, not your conversation.
Don't put your own or anyone else's personal data in your games.

Cookies and storage

Bitrir doesn't use advertising or tracking cookies, or analytics tools from other companies. Opening the website doesn't save anything in your browser; that's why we don't ask you to accept cookies. Only the following is saved, and only when you do something that needs it:

Your session (cookie bitrir_s): when you sign in with your account, so you stay signed in. It lasts 30 days or until you sign out.
Your language (cookie bitrir_idioma, which stores es or en): only when you choose a language yourself with the language selector (in the header, in the footer or in Settings › Language), to remember it on your next visits. It lasts one year. It's a technical cookie: it's saved because you ask for it, and it isn't used to track you.
Your games without an account (bitrir-datos: plus the game's name): when a game saves your stats or your progress.
An invitation (bitrir-invita): if you arrive through a friend's link and are about to sign in or create your account. It's deleted when you accept it.
Creating without an account (bitrir-invitado): your project's token, when you make a game without an account. Claiming your games (bitrir-reclamar): the code from your link, until you claim them or close the tab.
Notifications (a service worker and bitrir-push-de, or bitrir-push-nativo in the app): if you turn them on, until you turn them off or sign out. If you say “Not now”, bitrir-push-ofrecido keeps us from offering them to you again for 14 days.
Test mode (bitrir-pruebas). If you turn it on, the tab remembers that you're testing, so that activity is left out of the metrics and the player notifications. It's deleted when you leave test mode or close the tab.
A message (bitrir-aviso): when you delete your account, the notice that it has been deleted. It's removed as soon as you see it.
Only in the mobile app: the days you've opened it and the last time we asked you for a rating (bitrir-dias-app and bitrir-valoracion), so we don't ask you on your first day; and the link it was opened with (bitrir-arranque), until you close it. None of this leaves your phone.

Except for the session and language cookies, all of this stays in your browser and doesn't reach us. Anything without a time limit stays there until you delete it from your browser settings. Games run isolated on another domain (juegos-bitrir.videolibros.app), with no cookies and no access to any of the above.

Standalone apps: Granjeros

Granjeros is meant for people aged 14 and up and lets you play solo, offline and without an account. The app stores your preferences and progress locally. It doesn't ask for your age to play without an account. We don't send individual gameplay stats for guest players.

If you sign in with your account, we use the same friends, rooms, achievements, scores and ratings as on Bitrir. We store a session credential in the secure storage of iOS or Android; the server keeps a fingerprint of it, not your password. The session expires after 30 days or when you sign out. Pending saves are kept on your device and synced with your account when the connection comes back.

Guest games and each account's games are kept separate. Signing out keeps the local copy so you can continue later. Deleting your Bitrir account also deletes its local copy on the device you request the deletion from, and revokes mobile sessions. Recommendations for other games are our own, aren't personalized with your activity and don't use advertising identifiers. Promotions between farms count plays, skips and clicks per campaign and per day, without storing who saw them. You can turn on invitation notifications from Options if your device supports them.

What we use it for

Only to make Bitrir work (your account, your matches, your friends and your games), for safety and moderation, and to find out, without identifying you, whether people like Bitrir and how to improve it. We never sell your data or use it for advertising. The legal basis is the consent you give when you create your account and the legitimate interest in keeping the service secure and in measuring it without identifying you.

Accounts are for people aged 14 and up: in Spain, you can give your consent for this from age 14. If the age for giving it is higher in your country, you need permission from your mother, father or guardian.

Where and for how long

Bitrir's data is on Hetzner servers in Germany, inside the European Union. Games are served from juegos-bitrir.videolibros.app, on that same server.
We keep your account data for as long as you have the account.
Visits without an account are deleted after 24 months, unclaimed projects after 30 days and read notifications after 90 days.
The data of the people we contact about publishing their game is kept for the periods explained in that section.

Your rights

You can delete your account yourself, on the website or in the app, in Settings › Your account › Delete my account: just your Bitrir data or your whole Videolibros account. You confirm it with your email and password or, if you sign in with Google, with Google. Everything of yours is deleted right away, including your published games. If you can't sign in, email us at hola@bitrir.com from your account's email address.
You can ask for a copy of your data or have it corrected by emailing hola@bitrir.com from your account's email address.
You can also object to the processing of your data or ask us to restrict it.
You can file a complaint with the Agencia Española de Protección de Datos (the Spanish Data Protection Agency, aepd.es) or with the data protection authority in your country.

If we contact you about publishing your game

We look for games made with artificial intelligence that their authors have published on other websites and, sometimes, we write to them to suggest publishing them on Bitrir too. If we've written to you for that reason, you didn't give us your data: we saw it on public pages. Here's what we do with it.

What data: your username or the name you publish under, the links to your profile and your game, the public channel where you can be contacted (for example, the email address or account shown on your profile), the messages we send you and your reply. We don't look for any other data about you or build a profile of you: what we assess is the game.
Where it comes from: the public pages where your game or your profile is, such as itch.io, GitHub, X, Reddit, Hacker News and game jam pages.
Why, and on what legal basis: to suggest publishing your game on Bitrir, with your permission and credited to you, and to continue the conversation if you reply. The legal basis is our legitimate interest (Article 6(1)(f) of the GDPR) in offering Bitrir to people who already make games. We've weighed it against your interests: we only use data you've made public so people can find you, if you don't reply we remind you once at most, and you can say no with one word. We never publish anything of yours without your written permission.
Who sees it: the Bitrir team, who decide whom we write to. To find games and prepare messages we use automated tools, including artificial intelligence, from companies that process this data on our behalf. Some may be outside the European Union, for example in the United States; in that case we apply the safeguards the GDPR requires, such as the EU-U.S. Data Privacy Framework or standard contractual clauses. If we write to you on a platform (X, Reddit or another one), the message also stays there, under its rules. We don't sell or share your data with anyone.
How long:
- If your game doesn't end up being published on Bitrir, whether or not you reply, we delete your data 6 months after the last message.
- If you agree, we keep your permission and the conversation for as long as your game is on Bitrir and for 5 more years, as proof that you gave it. If you create an account to publish it, everything else follows the rest of this policy.
- If you say no or ask us not to write to you again, we delete everything else right away and keep only an opt-out record (the link to your profile, the channel we used to write to you and the date) so we don't write to you again. We keep it for as long as we keep looking for games on other websites.
Your rights: you can object at any time. Reply “stop” to the message or email us at hola@bitrir.com and we won't write to you again. At that same address you can ask us to see your data, correct it, delete it or restrict its use. You can also file a complaint with the Agencia Española de Protección de Datos (the Spanish Data Protection Agency, aepd.es) or with the data protection authority in your country. If you're under 14, let us know and we'll treat it the same as an opt-out.

Changes

If this policy changes, we'll let you know on Bitrir before the change takes effect.
