Privacy

Short version: your photos never leave your device.

Your photos and patterns

When you choose a photo, Numbrush processes it entirely inside your web browser. The photo, the pattern, the mixing recipes and the PDFs are never sent to our server or anyone else.

Your projects are stored in your browser's own storage (IndexedDB) on this device only, so you can come back to them. Settings such as canvas size and the paints you own are kept in local storage. Clearing your browser's site data, or deleting a project in My projects, removes them. We can't see or recover them.

What our hosting sees

The site is served by Cloudflare. Like any web host, Cloudflare processes standard request information such as IP address, browser type and the page requested, to deliver the site and protect it from abuse. Fonts are loaded from Google Fonts, which receives your IP address when your browser requests them.

We don't use tracking cookies, we don't have accounts, and we don't sell data.

Advertising

Numbrush may show sponsored placements or ads in the future to stay free. If an ad service that uses cookies is added, this page will be updated before it goes live to explain what it collects and how to opt out.
