Privacy Policy

This website

erwindegroot.nl is a landing page and a couple of pages describing the two apps, and nothing else. It has no user accounts, sets no cookies of its own, and runs no analytics or tracking scripts. Nothing you do on this page is recorded by it.

Fractalysis

Fractalysis is hosted here, at erwindegroot.nl/fractalysis/. Everything it renders is computed on your own device, in your browser. Nothing you explore or export is sent to a server, and the app keeps no accounts, no counters and no stored data of any kind.

PhotoSpiralysis

PhotoSpiralysis lives on its own website and is covered by its own policy, at photospiralysis.com/privacy-policy/. In short: your photos are processed entirely in your browser and never leave your device.

The tip button

The “Tip Me” button in the corner of the front page is provided by Ko-fi. To show it, the page loads a script from ko-fi.com, which means Ko-fi’s servers receive the standard details of that request — such as your IP address and browser type — whether or not you ever press the button. Ko-fi may also set cookies of its own.

If you do leave a tip, the whole payment happens with Ko-fi. This site never sees your name, email address or payment details. How Ko-fi handles your data is described in Ko-fi’s privacy policy.

Server logs

Like most websites, the hosting provider for erwindegroot.nl may keep standard server access logs (such as IP address and request time) for security and operational purposes. These are not used to track individual visitors.
