Everything is explained in more detail below.
Kokomo is run by Nordic Dynamic ehf., reg. no. 580711-0810, Bræðratunga 16, 200 Kópavogur, Iceland. The company is the controller of the personal data described here. Questions about privacy go to kokomo@kokomo.is.
This policy is based on the Icelandic Data Protection Act no. 90/2018 and the EU General Data Protection Regulation (GDPR).
Game progress and settings are stored in your browser (localStorage) and are not sent to us. This is needed so the games remember where you were and whether you chose a light or dark look.
Anonymous counting. When you open or finish a game we record the event: which game it was, whether the device is a phone, tablet or computer, and whether the page is in Icelandic or English. No identifier is attached, nothing is written to your device and we cannot link two visits together. We use this to know which games are played and what needs fixing. The legal basis is our legitimate interest in running and improving the site.
Error reports. If something breaks on a page, your browser sends us the error message, the page address and the browser type. These are deleted automatically after 30 days. The legal basis is our legitimate interest in keeping the site working.
Feedback. If you send us feedback, we store the text, which game it concerns and the browser type. Please don't write your name or other personal details in feedback. Feedback and error reports are collected in a task list on GitHub, and we use an AI tool (Claude by Anthropic) to sort them and find fixes. Feedback is deleted after 24 months.
The weather on the front page is fetched directly from Open-Meteo, a Swiss weather service. Your browser connects to it to do this, so it sees your device's IP address. Nothing else is sent to it.
Speaking practice. In “First steps in Icelandic” you can practise pronunciation with your microphone. This uses the speech recognition built into your browser, and the audio goes to the browser maker (for example Google in Chrome) but never to Kokomo. The microphone only starts when you press it.
Servers. As on every website, the servers that host Kokomo see your IP address when you load a page. Our hosting providers keep such connection logs for a short time for security. We don't use them to find out who you are.
Then measurements are added that tell us how people find Kokomo and whether they come back:
The legal basis is your consent. You can withdraw it at any time by clicking “Cookies” at the bottom of any page and choosing “Decline”. The measurement then stops and the number is deleted from your browser.
If you decline or don't answer the banner, only the anonymous counting from section 2 takes place.
An account is optional. It lets you keep your progress, palms and outfits across devices.
What we store:
Legal basis: The account itself and what comes with it is based on our agreement with you (the terms). Push notifications and marketing email are based on your consent.
The weekly leaderboard shows your display name, your points, your streak and your puffin's outfit. Anyone who visits Kokomo can see the list. Use a nickname if you don't want others to recognise you, and never use your full name as your display name if you are a child.
Your friends can also see your name and number of palms on the friends list.
Everything else connected to your account is only visible to you.
Kokomo is for all ages and many players are school pupils. That is why:
Some teachers send pupils to Kokomo, even though the site is made for fun and is not reviewed teaching material. For them, this matters:
We never sell personal data. The following service providers process data on our behalf and only for the purposes described here:
| Provider | What | Where |
|---|---|---|
| Supabase | Database, sign-in and sign-in emails | Ireland (EU) |
| Vercel | Website hosting | United States and servers around the world |
| Sign-in with Google, and Google Analytics if you accept | United States and EU | |
| GitHub (Microsoft) | Encrypted database backups and a task list of feedback and error reports | United States |
| Anthropic | AI help sorting feedback and error reports | United States |
| Open-Meteo | The weather on the front page (sees only the IP address) | Switzerland |
| Browser makers (Google, Mozilla, Apple) | Deliver push notifications if you turn them on | United States and elsewhere |
When data leaves the European Economic Area, the transfer relies on the EU-US Data Privacy Framework where the provider is certified, and otherwise on the European Commission's standard contractual clauses.
| Data | Kept for |
|---|---|
| Game progress in your browser | Until you clear your browser or sign out |
| Anonymous counting and measurements with consent | 24 months |
| Error reports | 30 days |
| Feedback | 24 months |
| Account and game data | As long as the account exists |
| Backups | 90 days |
| Google Analytics | 2 months (user data linked to an identifier for up to 14 months) |
When an account is deleted we delete the email address, the display name and all game data, and disconnect measurements from the account. Information in backups disappears when the backup expires, after 90 days at the latest.
You have the right to:
Send your request to kokomo@kokomo.is from the email address registered on the account, so we know the request comes from you. We reply within one month.
If our answer doesn't settle the matter, you can complain to the Icelandic Data Protection Authority, Persónuvernd (personuvernd.is).
Kokomo itself sets no traditional cookies. We use your browser's storage (localStorage) for game progress, settings and sign-in, which is needed for the site to work. Your choice in the cookie banner is also stored there.
The measurements in section 3 and the Google Analytics cookies are only switched on if you choose “Accept”. You can change your choice at any time under “Cookies” at the bottom of the page.
Data is sent encrypted, access to the database is restricted so each player only sees their own data, and backups are encrypted. Only the owner of Kokomo has access to the admin panel.
If we change this policy we update the date at the top. If a change matters to account holders, we let them know on the site or by email before it takes effect.
