Our mission
Why this has to be a nonprofit
A company giving this away free would eventually need to make money from it, and the only asset here worth selling is your portfolio data.
The incentive problem
Free tools that hold financial data tend to end up selling it.
Most portfolio trackers ask you to link a brokerage account and then hold that data on their servers indefinitely. That is not carelessness; it is the business model working as designed. A company needs revenue, the data is the asset, and every incentive points at collecting more of it.
Removing the profit motive is the only durable way to promise the data stays where it is. So Veluma is structured as a nonprofit and funded by donations and grants rather than by users, and the architecture is built so that breaking the promise would require rewriting the application rather than changing a policy.
Financial self-assessment should not require surrendering your financial life to a vendor.
What we commit to
Each of these is written so you could catch us breaking it.
- No paid tier, ever
- If a feature appears behind a price, this commitment was broken.
- No analytics on this site
- Check the network tab. Any request to a domain that is not Alpha Vantage breaks it.
- The math stays readable
- Every formula is a plain function with unit tests, named on the methodology page.
- Changes to the math are announced
- The changelog marks them. A number that moves without an entry breaks this.
How this is paid for
Donations and grants. Not by you, and not by anyone buying access to you.
Hosting static files is close to free, which is a deliberate consequence of having no servers, no database, and no accounts to administer. The remaining costs are development time and the domain.
We do not run a sponsorship slot, an affiliate link to a broker, or a “recommended products” section. Each of those would put a second party’s interest between the reader and the number on screen.
Why these four measurements
They are what a desk runs before judging a track record.
Return alone tells you almost nothing. Drawdown says how bad it got, the Sharpe ratio says what the return cost in volatility, and correlation says whether a portfolio that looks diversified actually is. These are the standard institutional figures, and there is no reason an individual should pay a subscription to see them.
They are also modest by design. Veluma does not forecast, score, or recommend. It measures what already happened, states how, and leaves the judgement to you.
