Built for clearer decisions
The essential indicators, without the noise.
Record purchases and sales, follow the remaining cost basis and put portfolio movements into perspective. The calculations are informational and use the same financial engine as the French interface.
Average purchase price
Read the average purchase price of the quantity still held, including purchase fees.
Performance
Separate market movements from contributions and withdrawals for a more useful reading.
Multiple portfolios
Organise different strategies while keeping one consistent local data structure.
Local by design
Your portfolio data stays on this device.
The app stores portfolios and transactions in the browser’s local storage. Current market prices are requested from an external price provider, without sending your holdings as a portfolio.
- One shared application
- The French and English interfaces use the same application, financial engine and local data. Switching language does not create a second portfolio.
- Backup and restore
- Export a JSON backup before changing browser or device, then restore it through the app when needed.
- PIN and biometrics
- The optional lock limits visual access on this device. It does not currently encrypt the data stored by the browser.
- Informational tool
- The tracker is not an official tax calculator and does not provide investment advice.
