Privacy
Last updated 13 November 2026
Kaleidosort is run by Dino Ćoralić, a private person in Bosnia and Herzegovina, who is responsible for the data described here (the "controller" under data protection law). The short version: no accounts, no ads, no tracking cookies, and your videos never leave your device.
What stays on your device
The sorting, the sound and the video recording all happen in your browser. Your videos are not uploaded anywhere. They are only saved when you tap Download, and after that they are yours to share or not.
Kaleidosort saves a few things in your browser's local storage so they are still there next time:
- your settings: colour theme, custom colours, background, sound voice, glow and rotation;
- your Pro pass, if you opened a Pro link. It holds a reference number, the plan and an end date, signed so it can't be faked.
This data is not sent to us. Clearing your browser's site data for kaleidosort.com deletes it. Local storage is not a cookie, and we use it only for features you use.
What we collect
- Hosting logs. Kaleidosort is hosted by Cloudflare. When you open the site, Cloudflare processes your IP address, browser type, the page you asked for and the time, so it can deliver the site and protect it from attacks and abuse. We don't keep our own copy of these logs.
- Anonymous visit counts. We use Cloudflare Web Analytics to see how many people visit, which pages they open, which site sent them, and their country and type of device. It uses no cookies, doesn't follow you to other sites and doesn't build a profile of you.
- Emails you send us. If you write to support, we get your email address and your message. Our support address forwards to a Gmail inbox (Google). We use your email only to answer you and delete it when it is no longer needed.
Fonts and images are served from kaleidosort.com itself. We don't load anything from Google Fonts, ad networks or social media sites.
Payments
Pro can't be bought yet. Before it goes on sale, this policy will name the payment provider and explain what it collects, so you can read it before you pay. We will never see or store your card details.
Why we may use this data
For visitors in the EU and UK: we handle hosting logs and visit counts because we have a legitimate interest in running a safe, working site and knowing roughly how it is used (GDPR Art. 6(1)(f)). We handle your emails to answer your request (Art. 6(1)(b) and (f)). We don't sell your data and don't use it for advertising.
Where the data is processed
Cloudflare and Google are based in the United States and may process data outside your country. Both use the safeguards required by EU law for this, such as the EU-US Data Privacy Framework and standard contractual clauses. Their own privacy policies are at cloudflare.com/privacypolicy and policies.google.com/privacy.
Your rights
You can ask what data we hold about you, and ask us to correct or delete it, limit how we use it, or give you a copy. You can also object to how we use it. Because Kaleidosort has no accounts, this mostly concerns emails you sent us. Write to support@kaleidosort.com and we will reply as soon as possible.
You can also complain to a data protection authority: in the EU, the one in your country; in Bosnia and Herzegovina, the Personal Data Protection Agency.
Changes
If we change this policy, we update the date at the top of this page.
