Privacy

Updated October 2026

Short version: the products you add and the routine Dermo builds stay on your device. We don't have accounts, we don't set cookies, and we don't use analytics or advertising trackers.

What stays on your device

Your products, their timing and the schedule are saved in your browser's local storage so they are there next time. An ingredient list you paste is read in your browser and not saved. You can delete everything with “Start over”, or by clearing this site's data in your browser.

Share links

A share link carries your product names, types and timing in the part of the address after “#”. Browsers don't send that part to our server; it is only seen by the people you send the link to.

What our hosting sees

Dermo is hosted by Vercel. Like any web server, it receives standard request information (such as IP address, browser type and the page requested) to deliver the site and protect it from abuse. Fonts are served from dermo.md itself, so no font provider sees your visit.

Changes

If we ever add something that collects information, such as a newsletter, this page will say exactly what, why, and how to remove it, before it goes live.
