Almost every tool you use to do your work is paid for by somebody who is not you. That arrangement has consequences, and they land on the person whose documents are involved, which is usually not the person who agreed to it.
Free office software is not charity. It is funded by knowing things about you: what you write, who you write to, what you search for on the way, and what that predicts about what you will buy. The product is good, often excellent, and the price is a permanent record of your working life held by a company whose interests are not yours.
The paid alternative asks for money and keeps the arrangement. You buy the licence, the subscription renews, the files still live on their servers, and the terms still change without asking you.
Both models share one assumption: that your work has to pass through somebody else's computer to be useful. That assumption is a business decision. It is not a technical requirement.
OBSCURA OS runs in the browser tab you already have open. The document you type, the spreadsheet you calculate, the contract you compare, the photograph you strip of its GPS coordinates: all of it is processed by JavaScript executing on your own machine, in your own memory.
There is no upload step. Not an encrypted one, not a “we promise not to look” one. There is no account, no password, no profile, and no server-side copy of anything you make. We cannot hand your files to an advertiser, a data broker, a court, or an attacker who breaches us, for the simple reason that we never receive them.
This is architecture, not a promise. A privacy policy is a statement of intent that can be revised. A tool that has nowhere to send your data cannot change its mind next quarter.
Anyone whose work involves other people's confidential material, where a leak is somebody else's problem before it is yours:
The ability to write something down privately, and to hand it to one specific person and nobody else, is not a technical nicety. It is the precondition for a source talking to a reporter, for a client being honest with their lawyer, for a person seeking help without it following them. When every tool that touches a document also reports on it, that ability quietly disappears, not by anyone deciding to end it, but by there being nowhere left to do it.
We are not going to overstate our part in that. This is software; it is not protection from a determined state adversary, and every tool on this site says on its own page exactly where its technique stops working. But the everyday case: the file that should never have left your laptop and did, because the only tool available wanted it on a server first: that case is solvable, and this is what solving it looks like.
Software costs something to build, so here is the honest accounting rather than a slogan.
Everything on the site, the Workspace Suite (documents, spreadsheets, slides, forms, drive, calendar, notes) and the Sovereign Suite (the privacy and document-defence tools), is free for personal use. No account, no trial, no feature held back, and no advertising. We used to run ads on the Workspace and sell a pass for the Sovereign tools. We stopped both: ads meant an advertising network watching which browsers visited, and a paywall meant a tool that only worked for people who paid. Neither belonged on a site that exists to keep your work yours.
Two things are paid, and both are optional. If the site is worth something to you, there is a pay-what-you-want support option: a gift, nothing promised in return. If you use OBSCURA OS inside a business or for client work, a one-time commercial licence covers that. The software behaves exactly the same either way; the licence is permission, not a feature key.
We are a small operation and we would rather be paid by the people using the software than by people buying access to them.
The Workspace Suite needs no signup and no payment. If you want to see the principle demonstrated in ten seconds, the photo metadata checker will show you the exact coordinates your phone wrote into your last photograph: reading it in your browser, without the image ever being uploaded.
