This website
This website uses no cookies, no scripts, no analytics or advertising services and loads no third-party fonts or content. It is delivered via Cloudflare Pages. Cloudflare processes technically necessary connection data (e.g. IP address, time, requested file) to deliver the site and protect it against attacks. We do not analyse this data ourselves.
The app
- All data (portfolios, transactions, notes, imported files) is stored only on your device. There is no user account and no server of ours.
- With an app PIN, data and original files are encrypted on the device.
- The app contains no ads, no trackers and no analytics libraries.
When the app connects to the internet
- Update prices & data (only when you tap it): prices are requested from public price sources, including Onvista, using security identifiers (e.g. ISIN). No personal data or holdings are transmitted; the provider technically sees your IP address.
- AI questions (optional): only if you enter your own OpenRouter key and send a question. Name, type, entry price and long/short of your positions are sent – percentage shares only if you switch that on. You see the exact text before sending.
- Report a bug / contact: opens your own mail app. You decide what to send.
Backups
You save exports (CSV, encrypted ZIP) yourself wherever you like. We receive nothing.
