Privacy policy

Last updated: 14 November 2026. This policy covers the Sketch Fury website (sketchfury.com) and the Sketch Fury app for Android and iPhone.

What we collect

When you just play

Nothing that identifies you. The game counts how often each fighter is picked and how often it wins, as plain totals. Your settings (sound, difficulty, your online name) are stored on your own device.

When you play online

You choose a player name. Other players see it, and it appears on the leaderboards with your number of wins. Please do not use your real name. Your internet address is used while you are connected, to match players and to stop the leaderboard being cheated; it is not stored with your name.

When you send a sketch

• The picture. Photos are re-saved on your device before they are sent, which removes hidden information such as where and when the photo was taken.
• The name of the fighter, and, if you choose to give them, its powers and a "drawn by" name. Please use a first name or nickname only.
• The internet (IP) address the sketch was sent from, and the time. This is used only to limit how many sketches one connection can send and to block misuse. It is never shown publicly.

If a sketch is approved, the picture (a cleaned copy), the name of the fighter and the "drawn by" name are shown publicly in the game, in the app and on the website. A sketch that is not approved is never shown to anyone.

In the app

• An install code. The app makes up a long random code the first time it runs. It is how the app knows which sketches are yours without an account. It is not the advertising ID of your phone, it is not linked to your name, and our server only keeps a scrambled (hashed) form of it.
• A notification token, only if you turn notifications on. It lets us send "your fighter is ready" messages to your phone through the Firebase Cloud Messaging service from Google (and the Apple notification service on iPhone). Turning notifications off in the Settings of the app removes it from our server.
• On your device only: a small copy of the sketches you sent, a drawing you have not finished, and your settings.

The app does not read your contacts, your location or your photo library. It only sees the one picture you choose or take when you make a sketch.

Counting visits

We count how many people visit, which pages they open, which country and kind of device they come from, and totals such as how many fighters were shared. These are plain totals. We do not use cookies for this, we do not use any analytics company, and nothing is stored about any one visitor. To count a person only once a day, your internet address and browser type are scrambled together with a random key that is thrown away when the day ends.

When something goes wrong

If the app or the game hits an error, it sends our server a short report so we can fix it: the error message and where in our code it happened, which screen was open, the app version, the kind of device and browser, and the screen size. The report does not say who you are. It does not include your install code, your name, your sketches or your internet address, and it goes to our own server only, not to any other company.

When you report a fighter

We keep which fighter it was, the reason you picked, anything you wrote, and the internet address the report came from, so a person can look into it.

How sketches are processed

Sketches are reviewed and turned into fighters by automated AI tools, with a person able to step in. To do that, the picture and the words sent with it are processed by Anthropic (the Claude AI models, for review and design) and Google (the Gemini image models, for the artwork). We send them only the sketch and its words, never the internet address or the install code.

Who else handles data for us

• Cloudflare delivers the website and protects it from attacks, so it handles the internet traffic to and from sketchfury.com.
• Our hosting provider runs the server where sketches, fighters and leaderboards are stored.
• Google Firebase Cloud Messaging and the Apple Push Notification service deliver notifications, if you turn them on.
• Anthropic and Google, as described above.

We do not sell personal information, and we do not share it with anyone for advertising.

How long we keep it

• An approved sketch and its fighter stay in the game until we, or you, take them down.
• The original upload, the words sent with it and the internet address are kept with the sketch for as long as the sketch is kept.
• Leaderboards are kept by day. A player name can be removed on request.
• The install code and notification token are kept while the app is in use, and removed when you turn notifications off or ask us to.

Children

Sketch Fury is made for families, and many of its artists are children. That is why there are no accounts, no chat, no adverts and no tracking, why every sketch is checked before anyone can see it, and why we ask for a first name or nickname only. If you are under 13, please ask a parent or guardian to help you send a sketch. A parent or guardian can ask us at any time to remove the sketch, fighter or player name of a child, and we will.

Your choices

• Remove a sketch or fighter: write to [email protected] with the ticket code or the name of the fighter.
• Remove a leaderboard name: write to the same address with the name.
• Notifications: switch them off in the Settings of the app, or in the settings of your phone.
• Everything stored on your device: clear the site data in your browser, or uninstall the app.
• Depending on where you live, you may also have the right to see, correct or delete the information we hold about you, and to complain to your data protection authority. Write to us and we will help.

Changes

If this policy changes, the new version will be published on this page with a new date.
