▸ What is DOMsters?

A browser extension that turns any web page into a turn-based creature-collection RPG. It's not a bag of random monsters: the species comes from the domain and the page's real structure (elements, links, forms, depth). The creature of a news site looks nothing like the one from a shop or a forum.

▸ Privacy (upfront — I owe you this)

It's an extension with permission over websites, so here's what it does and what it does not:

  • It does not read your history or your tabs (it doesn't request those permissions).
  • It does not send page content: only the domain (e.g. from opera.com/gx only opera.com travels) and a few numeric DOM metrics. Never the path, params, or what you type.
  • Zero third-party trackers.
  • Unobfuscated code: check it yourself in the network tab.

Every detail (what is stored, where, for how long and how to delete it) is in the privacy policy.
