Try the demo
demo.badlen.fr is Badlen itself, holding a sample household portfolio: sixteen years of history, a dozen accounts, eighteen months of operations, a budget and goals. There is nothing to install and no account to create: the page opens on the overview, in the language of your browser.
Your data stays in your browser
Section titled “Your data stays in your browser”The whole application runs inside the page, the part an installed instance runs on its server included, along with its database. The sample data is generated when the page opens, dated today. What you read and what you type stays in that tab: the page sends nothing anywhere, not even a request for quotes.
The one thing that leaves is a visit count. The demo loads the project’s own Umami counter, which receives the page address, the language and the screen size, with no cookie and no figure from the portfolio. Nothing is sold or shared, and the counts are kept for a limited time. A link under Demo, in the middle of the top bar, Don’t count my visits, stops it, and so does your browser’s Do Not Track setting.
The first visit downloads about 8 MB, and preparing the demo then takes a few seconds; a ring shows how far along it is.
Everything that only touches the portfolio
Section titled “Everything that only touches the portfolio”Every write that stays inside the portfolio works, with the same rules as an installed instance:
- add, edit and delete operations, accounts, holdings and properties;
- set goals and a budget, and follow the effect on every screen;
- rename, add and reorganise categories, and recategorise operations;
- fill in your situation under Settings, which the projections and advice read;
- follow the journey and the course;
- export the portfolio as a JSON file.
Moving from screen to screen keeps your changes. Reloading the page erases them, and the demo starts again from the sample data. The word Demo, in the middle of the top bar, is there to remind you; a click on it shows the whole sentence.
Locked
Section titled “Locked”What has no meaning without a server, or would mislead you into thinking it worked:
- the password, two-factor authentication, sessions, the username and e-mail address, and deleting the account;
- API keys and data-provider keys;
- the hand-over: the letter, its printable copy and the relay to a relative;
- restoring a backup and the passphrase-sealed export;
- refreshing quotes, and rebuilding history from them;
- administration.
In the settings, these cards stay in view under a veil, with Locked for the demonstration account laid over it. Show anyway lifts the veil so you can read them, and unlocks nothing; it is back the next time you open the page.
