We collect nothing. PAPER is a static page with no backend, no accounts, and no analytics. There is nothing to send your data to.
Your positions live on your device. Everything you enter is stored in your browser's localStorage, on your device only. It never leaves your browser. Clearing site data erases it, so export a backup from the Rules tab before switching devices.
Optional keys stay local. If you add a free Finnhub or Twelve Data key for stock quotes, it is stored in the same localStorage and sent only to that provider's API, never anywhere else.
No cookies. PAPER sets no cookies of its own.
Third parties. The app fetches public price quotes from CoinGecko (crypto) and, if you add a key, from Finnhub or Twelve Data (stocks). Those requests go to those providers when you use the app.
