Privacy Policy

Last updated: 20 October 2026

Injoker is a small game made by an independent developer ("we", contact below). This policy explains what happens to information when you play Injoker on Android (the app net.relifes.injoker on Google Play) or in a web browser (injoker.relifes.net).

The short version

• Injoker does not need an account, and we do not collect, sell or share personal information.
• There are no ads, no in-app purchases and no analytics or tracking in the game. The website counts visits without cookies (see Website).
• Your progress stays on your own device.
• One optional feature of the Android app uses Google: the global leaderboards. Only if you sign in to Google Play Games are your results sent to Google, to rank you. See below.
• The web version has an optional world ranking. Only if you type a name for it are your results sent, with that name, to our leaderboard server. See below.

Android app

The Android app requests no permissions. It stores a few things on your device only, in the app's private storage:

• your records (best score, best combo, best survival time), your 10 best runs in each mode, your best time against each boss, your gold, the materials you found and the items you bought in the shop (with game gold only),
• your settings: sound on/off, recipe hint on/off, and whether you have finished the tutorial.

We cannot see this data. Unless you use the global leaderboards described next, it never leaves your device.

Global leaderboards (Android, optional)

From version 1.7.0 the Android app can show global leaderboards through Google Play Games. This is optional: the whole game works without signing in, and a player who is not signed in is not ranked globally and sends nothing.

• If you have a Google Play Games profile, Google may sign you in to it when the game starts; otherwise you are only asked when you open the global ranking yourself.
• While you are signed in, the game sends two kinds of results to Google Play Games: your score in PLAY and your survival time in SURVIVAL. They are stored by Google with your Play Games profile and shown on the leaderboards next to your Play Games name and avatar, to the people your Play Games settings allow.
• The game itself never reads, stores or sends your name, avatar, e-mail address or anything else from your Google account. We run no server of our own and receive none of this.
• Google processes this information under its own privacy policy.

Web version

In a browser the same data is kept in the browser's local storage on your device.

The game page also shows a visitor counter. The first time a browser opens it, it sends one anonymous request to a free counting service (abacus.jasoncameron.dev) to add one visit; no name, account or identifier from the game is sent. The pages are hosted on GitHub Pages. Like any website, these services receive the technical details of each request (such as your IP address) as part of normal internet traffic; Injoker does not collect or keep them. See the GitHub privacy statement for GitHub Pages.

Website (home page, guide, leaderboard)

The pages around the game (the home page, the guide and the leaderboard) set no cookies and load their fonts and images from our own site.

• Trailer: the home page shows a picture of the trailer. Only when you press it, the video is loaded from YouTube (in its privacy-enhanced mode, youtube-nocookie.com), and Google then processes the request under its own privacy policy.
• Visit statistics: the pages may use Cloudflare Web Analytics to count visits. It uses no cookies and no local storage, does not identify you or follow you across sites, and only gives us totals (pages viewed, country, browser type, referring site). See the Cloudflare privacy policy.
• Leaderboard: the home page and the leaderboard page read the public top names and scores from our leaderboard server; they send nothing about you.

World ranking (web version, optional)

The LEADERBOARD screen of the web version has a WORLD RANKING button. The first time you open it, the game asks for a name (2 to 12 letters, digits or spaces; it does not have to be your real name). Only after you have typed one, the result of each run you finish is sent to our leaderboard server, together with: that name, the board (PLAY or SURVIVAL), the score, the length of the run and the time it was sent. Your best results from this device are sent once when you set the name.

The server also stores a one-way, salted hash of your IP address, only to limit how many results one player can send in an hour; the address itself is not stored. No account, e-mail address, device identifier or location is collected. The server runs on Cloudflare (Workers and D1), which receives the technical details of each request as part of normal internet traffic.

The names and scores are public: anyone can see the ten best of each board. Results are kept until we remove them; a name that is offensive or impersonates someone is removed.

Feedback form (support page, optional)

The support page has a form to write to us. Only when you press Send, it sends us by e-mail: the name you typed (it does not have to be your real name), your message, your device type as your browser reports it (browser and system, so we can reproduce a bug) and the time. It goes through EmailJS, a service that delivers the message to our mailbox. We use it only to read and answer your message, and delete it on request. Nothing is sent from the game itself: the FEEDBACK button in the game only opens the support page.

Deleting your data

What the game stores is on your device, so you are always in control of it:

• Android: uninstall the app, or open Settings → Apps → Injoker → Storage → Clear storage.
• Web: clear the site data for injoker.relifes.net in your browser settings.
• World ranking (web): write to us (contact below) with the name you used, and we delete every result sent under it.
• Feedback form: write to us (contact below) with the name you used, and we delete your messages.
• Global leaderboards: your results there belong to your Google Play Games profile. In the Play Games app, open Settings to delete your data for a single game or your whole Play Games profile; you can also hide your game activity there. To stop sending results, sign out of Play Games for Injoker in the same place.

Apart from the world ranking of the web version and the messages you send us, we hold no copy of your data.

Google Play

If you install Injoker from Google Play, Google processes information about your download and device under its own privacy policy. We only receive the aggregated, anonymous statistics Google Play Console shows every developer (such as install counts and crash reports).

Children

Injoker is not directed at children under 13, and it does not knowingly collect information from anyone.

Changes

13 October 2026: added the optional feedback form of the support page (a name you type, your message).
3 October 2026: added the optional world ranking of the web version (a name you type, your results).
