About this project
A small set of privacy tools that run in your browser, built so that anyone can use them.

The name
Pseudononymous is a crossing of pseudonymous and anonymous. That blend describes the project fairly well: the goal is not to disappear from the internet, which is close to impossible anyway, but to decide which version of you is exposed, and how much.
Why it exists
Plenty of sites offer to strip the metadata from a photo, and almost all of them ask you to upload it to their server first. It is an odd bargain: to protect your privacy, hand it over. Here there is no server to upload anything to, and that is not a technical detail — it is the whole idea.
The other reason is simpler: almost every privacy tool is written for people who already know about privacy. This one is built so that your grandmother and your nine-year-old niece can both use it, in their own language, without signing up or configuring anything.
What is here now
- Five tools, finished and usable, not a prototype.
- Everything runs in your browser. No accounts, no cookies, no third-party analytics.
- Spanish and English from day one, each with its own URLs.
- Light and dark themes, both designed with the same care.
- Everything is checkable from your own browser, with nothing to take on trust.
What comes next
The next phase adds the tools that genuinely need a server: checking whether your email appears in breaches, finding how many platforms a username exists on, and an exposure score tying it together. They come later on purpose: they bring API keys, legal considerations and a real attack surface, and shipping five finished things beat shipping eight half-built ones.
After that, a learning section: interactive challenges for understanding how tracking, phishing and passwords actually work, by doing rather than reading.
How to help
The most useful thing you can do is tell us when something does not work. A security report is the most welcome of all, and the security page explains how to send one. But if you spot a translation that reads oddly, an explanation that does not land, or a tool that misbehaves on a particular file, that counts for a lot too: real usability only shows up when real people use the thing.
