Service Policy#

Last updated: 19-10-2026 · Privacy policy and terms of service for Uniplay

Uniplay is a library of games you play in your browser at play.unikia.es or in the Uniplay app for macOS and Windows. It's run by Rubén Robles Manrique ("Unikia", "we"), 48841641Z, Valencia, Spain. You can reach us at [email protected] about anything on this page.

This page has two parts: how we handle your data (the privacy policy) and the rules for using Uniplay (the terms of service). By using Uniplay you agree to the terms; the privacy policy explains what happens to your data whether or not you have an account.

In short#

• You can play without an account. Your saves, achievements and settings then stay on your device.
• An account is optional: sign in with Google to keep your progress across devices and to add buds. We keep your email address, the name and avatar you choose, and your game progress.
• We don't show ads, don't sell your data and don't use tracking or analytics cookies.
• Playing with buds connects your device directly to theirs, which shows them your IP address.
• You can download everything we keep about you, or delete your account, from Settings → Account at any time.

Privacy policy#

Who is responsible for your data#

Unikia is the controller of the personal data described here, under the EU General Data Protection Regulation (GDPR) and Spain's Organic Law 3/2018 (LOPDGDD). Write to [email protected] to exercise your rights or ask about your data.

What we collect, and why#

Without an account#

Uniplay works without an account. Saves, achievements, time played, your name, avatar and settings are kept in your browser's storage (or the app's) on your device, and never reach our servers. Clearing your browser's site data deletes them.

To serve the site, our servers receive the usual details of each request: your IP address, the address requested, the time, and your browser's user agent. They're used only to deliver the site, keep it secure and fix problems, and are deleted after [LOG RETENTION, e.g. 14 days]. Legal basis: our legitimate interest in running a secure service (Art. 6(1)(f) GDPR).

With an account#

When you sign in with Google, Google tells us your Google account identifier and your email address. We don't receive your Google password or access to anything else in your Google account. With your account we keep:

Legal basis: the performance of our agreement with you (Art. 6(1)(b) GDPR), as these are what the account is for.

Sharing with your buds. Your buds see your nickname, avatar and whether you're online and what you're playing. They see your achievements and time played only if you turn on Share my profile with buds, and you can turn it off at any time.

Reviews you write are public, shown with your nickname and avatar, the version you played and how long you played it. Admins can hide a review that breaks the rules below, with a reason.

Feedback you send (bug reports, ideas, requests) is kept with your account so we can answer it. If you leave Include technical details on, it also carries your browser and system, screen size, input device, the Hub's version and recent errors. Legal basis: our legitimate interest in fixing and improving Uniplay.

Publishers who submit games also give us the games' files and details, the publisher's name and picture, and which accounts are its members. A publisher's name, picture and games are public.

Playing with others#

Uniplay's rooms, chat, voice calls and co-op connect your device directly to the other players' devices (peer-to-peer, through WebRTC). This means the other players in a room can see your IP address, as in most online games. Chat messages and voice go straight between players: we don't receive, record or keep them.

To find each other, devices exchange connection details through public Nostr relays run by third parties (currently nos.lol, relay.sigit.io, purplerelay.com and others listed in the source code), and through public STUN servers run by Google and Cloudflare, which see your IP address. Your online status is published to the relays encrypted, so only your buds can read it; the relays see that an anonymous key published something, and when.

In the desktop app#

Uniplay for desktop keeps your sign-in in your system's keychain (macOS Keychain or Windows Credential Manager), and the games you download in the app's folder on your computer. When it checks for updates it sends us its version and your system and processor type (such as macOS on Apple silicon).

Cookies and storage#

We use one cookie, which keeps you signed in, plus a short-lived one during sign-in. Both are strictly necessary for the account you asked for, so they need no consent. Uniplay also keeps your progress and settings in your browser's local storage, as described above. There are no advertising, analytics or tracking cookies.

Who else handles your data#

We don't sell your data or share it with advertisers. These providers process it for us, under data processing agreements:

The Nostr relays and STUN servers above are public services we don't control; they only receive what's needed to connect players.

How long we keep it#

We keep your account data until you delete your account. Sign-in sessions end 180 days after they were last used. Feedback is kept while your account exists, and server logs for 365 days. When you delete your account, everything tied to it (progress, buds, reviews, feedback and sessions) is deleted at once, except where the law requires us to keep something.

Your rights#

You can access, correct, delete, or download your data, object to or restrict its processing, and withdraw any consent, by writing to [email protected]. You can also do most of this yourself:

• Download your data from Settings → Account → Download my account data, as a JSON file.
• Delete your account from Settings → Account.
• Change your name and avatar in Settings → Profile, and what your buds see in Settings → Account.

If you think we've mishandled your data, you can complain to the Spanish Data Protection Agency (Agencia Española de Protección de Datos, aepd.es) or your own country's authority.

Children#

You need to be at least 14 to create an account (the age at which Spanish law lets you consent to this on your own); younger players can play without one. If you believe a child under that age has an account, tell us and we'll delete it.

Terms of service#

Using Uniplay#

Uniplay is free to use. You may play the games on it for your own personal, non-commercial use. Accounts are personal: don't share yours or sign in as someone else, and keep your Google account secure, as it's how you sign in.

Behaving well#

Don't use Uniplay to:

• harass, threaten, or impersonate other players, or post hateful, sexual, or illegal content in nicknames, avatars, reviews, chat or voice;
• cheat in ways that affect other players, or tamper with achievements, saves or rankings stored on our servers;
• attack, overload, or probe Uniplay or its players' devices, or reach parts of the service you weren't given access to;
• send spam, or use Uniplay to promote other services.

You can block any player from your buds list. We may hide content, or suspend or close accounts, that break these rules, and will tell you why unless the law or someone's safety prevents it.

Your content#

You keep the rights to what you write (nicknames, reviews, feedback). You give us a free, worldwide licence to store, show and adapt it as needed to run Uniplay, for as long as it's on Uniplay. Feedback you send can be used to improve Uniplay without owing you anything.

Games and publishers#

The games on Uniplay are made by their publishers, who own them and are responsible for them. Each game has its own licence and may be all rights reserved. Publishers who submit a game confirm that they have the rights to it and to everything in it, and give us the right to host, review, show and distribute it on Uniplay, in the browser and in the desktop app, until they remove it. We review games before they go live, but we can't guarantee every game works on every device, and we may remove a game at any time.

Uniplay's own software#

Uniplay's code (the site, its server and the desktop app) is open source under the MIT licence; the open-source software it's built with keeps its own licences, listed on the Licences page. The Uniplay and Unikia names and logos aren't covered by those licences.

Availability and changes#

We work to keep Uniplay running, but it's provided as it is: it can be unavailable at times, and we may change or end features, or the whole service, with reasonable notice where we can. The desktop app updates itself after checking each update's signature.

Liability#

We're responsible for harm we cause through our intent or gross negligence, and as the law otherwise requires. As Uniplay is a free service, beyond that we aren't liable for lost data, lost progress or indirect losses. Nothing here limits your rights as a consumer under Spanish and EU law.

Ending#

You can stop using Uniplay and delete your account at any time. We may close an account that seriously or repeatedly breaks these terms.

Changes to this page#

When we change this page we'll update the date at the top, and tell you in Uniplay before important changes take effect. If you don't agree with them, you can delete your account.

Law#

These terms are governed by Spanish law. If you're a consumer, you can also bring a claim in the courts where you live, and keep the protections of your country's law.
