Sollus started as a personal itch and turned into a position: your financial history is not raw material for someone else's business model.
Every expense tracker I tried began the same way — a sign-up screen. Before showing a single number, they wanted an email, a password and, often, read access to a bank account. The apps were competent. The trade was not.
A ledger of what you buy is one of the most revealing datasets about a person that exists. It shows where you were, what you eat, who you support, when your habits changed and what you were worried about. Handing that to a company whose revenue depends on knowing things is a strange default, and it's a default almost nobody chooses deliberately.
So Sollus was built the other way round. No account, because there's nothing to sign into. No cloud, because there's no server. No analytics SDK, because the app has nothing to phone home about. What's left is the part that was always the point: a fast, clear way to see where your money goes.
It shipped as version 1.0 on Google Play in 2026, free and ad-free, in seven languages, and it will keep being developed the same way.
Mission
Understanding your own money should not require surrendering it as data. The goal is an app good enough that people choose it on quality, and private enough that they never have to weigh that choice against a risk.
A promise in a document can be revised. A product with no server cannot quietly start collecting. We prefer designs where the guarantee is structural.
Software that stops working without a connection has made your data someone else's dependency. Everything here runs locally, first and always.
Tracking an expense has to be faster than not bothering. If the interaction takes longer than the purchase did, the app has failed.
No fake urgency, no engagement loops, no notification you didn't ask for. If the app isn't useful, it should be easy to leave — exports are one tap away.
No 'bank-grade encryption' theatre. The privacy policy is written to be read, and the Play Data Safety declaration says 'no data collected' because that's true.
The features people rely on today will not move behind a paywall later. Premium adds new things; it never repossesses old ones.
The near-term work is depth rather than breadth: better insights, better planning, and an optional Premium tier so the app can be sustained without advertising.
After that, the hard one — cloud sync. It only ships if it can be end-to-end encrypted, opt-in, and genuinely optional, with local-only remaining a first-class way to use the app. If that turns out to be impossible to do honestly, it doesn't ship.
Longer term: iOS, home screen widgets, shared household budgets and investment tracking. The roadmap page has the current ordering.
The long view
The ambition isn't to become a bank, a marketplace or a data business. It's to still be here in ten years as a small, fast, trustworthy app that a few hundred thousand people quietly rely on — and to have never once had a breach to disclose, because there was never anything to breach.
The argument is more convincing after five minutes of using it.
