Kalejdo – privacy and cookies
Applies to the Kalejdo app for Android and to kalejdo.app · Last updated 12 November 2026Kalejdo is a kaleidoscope you build yourself. It is published by Gr8eam AB, Sweden. We collect as little as we can: there is no advertising, no tracking and no analytics in the app or on the website.
Using Kalejdo without Pro
Your kaleidoscopes and settings are stored on your own device only (in the app, or in your browser's local storage). They are not sent to us. The app and the website fetch the picture libraries from kalejdo.app; like any web server, ours sees the IP address of each request and keeps it briefly in server logs to keep the service running and to stop abuse.
The first time the app starts it creates an anonymous account on our server: a number and a random secret key. It contains no name, e-mail address or device identifier and is only used to tell which libraries the app may show.
Kalejdo Pro (subscription)
Pro is a monthly subscription that you buy in the app through Google Play. Google handles the payment; we never see your card details, name or address. To check that a subscription is active we store the purchase token and order number that Google Play gives the app, together with the date the paid period runs to, on your anonymous account.
With Pro you can also:
- Sign in on the web by scanning a QR code with the app. The website then sets a cookie that keeps you signed in (see below).
- Build your own library on the website. The pictures you upload are stored on our server so that they can be shown in your browser and in your app. Only you can see them, unless you share a kaleidoscope that uses them.
- Share a kaleidoscope with a link. Anyone who has the link can open it. We store the kaleidoscope, its name and a preview picture.
- Give us an e-mail address (optional). It is used for one thing only: to warn you before a locked library is deleted.
When a subscription ends
When Pro ends, the Pro libraries, your own library and your shared links are locked. Your own library and your shared kaleidoscopes are kept for three months so that you can get them back by subscribing again. If you have given us an e-mail address we tell you when Pro has ended and remind you at least 14 days before anything is deleted. After that the pictures and the shared kaleidoscopes are deleted for good.

Permissions in the Android app
- Internet – to fetch the libraries, check the subscription and share kaleidoscopes.
- Vibration – a short buzz when you shake the kaleidoscope.
- The QR code is read by Google's code scanner; the app itself has no camera permission and never sees the camera picture.
- Pictures you save are written to Pictures/Kalejdo on your phone. The app cannot read your other pictures.
Deleting your data
Remove a picture from your library or stop sharing a kaleidoscope and it is deleted from our server straight away. Clearing the app's data or uninstalling the app removes everything stored on the phone. To have an account and everything linked to it deleted from our server, or to ask what we hold, write to info@gr8eam.com. A subscription is cancelled in Google Play (Play Store > Payments and subscriptions > Subscriptions).
Legal basis and contact
We process the data above to deliver the service you have asked for (contract) and to keep it secure (legitimate interest). Data is stored on our own server in Sweden. You have the rights given by the EU General Data Protection Regulation, including the right to complain to the Swedish Authority for Privacy Protection (IMY).
