Privacy
naganitro is designed with privacy as the default. No accounts, no personally identifiable information, no third-party tracking on the live dashboard.
What we collect
We do not collect names, email addresses, phone numbers, or any other personal information. There are no user accounts.
Anonymous device identifier
When you first visit, your browser generates a random UUID (universally unique identifier) and stores it in localStorage. This is sent with each API request as the X-User-Id header so the server can keep your personal watchlist separate from other visitors. It is not linked to your name, email, IP address, or any external identity.
If you clear your browser data, you get a fresh UUID and your previous watchlist will no longer be associated with you on the server side (the data remains in the database but is orphaned — no way to retrieve it without the original UUID).
Data stored on our servers
Tied to your anonymous UUID, we store:
- Your watchlist (ticker symbols + the thresholds you set)
- System-generated buy/sell signals for those symbols
- Price history snapshots (for technical analysis)
We do not store your browsing behavior, your chat history with the AI Q&A panel (that lives only in your browser), or any third-party-trackable identifier.
Data stored only in your browser
The following stays in your browser's localStorage and is never transmitted to our servers:
- Your anonymous UUID (sent only as a per-request header, never logged)
- Your Anthropic API key, if you provide one for the AI Q&A panel (it's sent as a per-request header which we forward directly to Anthropic and immediately discard)
- Your AI Q&A conversation history
- The "seen symbols" list for buy-recommendations rotation
- Whether you've dismissed the demo banner
Third parties
Pages connect to:
- Cloudflare — hosts the site. Cloudflare may log standard request metadata (IP address, user agent, timestamps) for ~30 days for security/abuse purposes per their privacy policy. We do not have access to these logs.
- Anthropic — only when you use the AI Q&A panel with your own API key. Your queries (with watchlist context) are sent to Anthropic and billed to your account. See Anthropic's privacy policy.
- Yahoo Finance and FRED — server-side data fetches only. Your browser never connects to them directly.
Cookies
naganitro does not set any cookies for tracking, analytics, or advertising. The only client-side state is in localStorage (described above).
If we later enable contextual ads on /stock/* and trust pages, this section will be updated with the standard ad-network cookie disclosure. The live dashboard at / will remain ad-free.
Forget my data
The footer of every page has a "forget my data" link. Clicking it wipes everything from your browser's localStorage (UUID, API key, chat history, all settings) and reloads the page with a fresh anonymous identity.
Your server-side data tied to the old UUID becomes inaccessible but will remain in the database. If you want it permanently deleted, contact me via the feedback form on the dashboard with your old UUID and I'll remove it manually.
