πŸ”’ Technically verifiable

Verify yourself that Alpha sends zero data to our servers

We say everywhere that your analyses stay 100% local. Easy to claim. Here's how to verify yourself in 30 seconds using tools already installed in your browser. No blind trust required.

The reproducible tutorial (Chrome / Firefox / Safari / Edge)

1

Open Alpha Terminal

Go to alpha-terminal.app and click Get started. You can enter a free API key (GitHub Models, Cerebras…) or click "Access without a key" to explore.

2

Open your browser DevTools

Keyboard shortcut:

Go to the Network tab. Tick "Preserve log" at the top.

3

Filter requests by domain

In the Network panel filter bar, type:

alpha-terminal.app

This shows only requests to our servers (not to Anthropic, OpenAI, Lemonsqueezy, etc.).

4

Run an analysis

Pick a stock (e.g. AAPL) and run a Quick Analysis or 10-K Decoder. You'll see requests scrolling in real time.

5

Observe the result

Throughout the analysis, the panel filtered on alpha-terminal.app should show:

πŸ“­ No requests.

All requests go directly to the AI provider you chose (api.anthropic.com, api.openai.com, generativelanguage.googleapis.com, etc.) β€” never to our servers.

What goes out, and where

DataDestinationOur server?
Analyzed ticker (AAPL, BTC…)Chosen AI API❌ No
Your promptsChosen AI API❌ No
Your portfolio (Wealth)Browser localStorage❌ No
Your RAG documentsBrowser IndexedDB❌ No
Financial data (prices, financials)FMP / Polygon / Yahoo / etc.❌ No
License activationapi.lemonsqueezy.com❌ No (their server)
Anonymous analytics (page visits)plausible.io❌ No · cookieless · IP anonymized
⚠️ Transparent note: the only thing that goes through our servers is loading the app itself (HTML, CSS, JS, images) β€” like any web site. But once loaded, the app runs entirely in your browser. That's the principle of a client-side PWA.

Technical architecture: why it's possible

Alpha has no backend for analyses. It's a deliberate design choice. Here's how each component works:

🧠 AIsYour prompts go directly to api.anthropic.com, api.openai.com, etc. via fetch() in your browser. No middleware on our side.
πŸ’Ύ Personal dataWealth, RAG, past analyses: everything stored in browser IndexedDB + localStorage. No server DB.
πŸ” API key vaultYour keys are encrypted AES-GCM-256 with your passphrase (PBKDF2 100k iter). The encrypted vault stays local. We never see it.
πŸ“Š Financial dataPrices, financials, news: direct calls to public APIs (FMP, Polygon, Yahoo, FRED) using keys you provide or free endpoints.
πŸ’³ PaymentLemonsqueezy handles checkout. They send us a webhook with your email to activate the license. No other data passes through us.
πŸ“ˆ AnalyticsPlausible.io in anonymous mode (cookieless, hashed IP). Public stats. No individual tracking possible.

What we CAN'T do (even if we wanted to)

Open code = open audit

You can inspect the frontend source code directly in your browser:

β†’

Verify the source code yourself

1. Cmd+Option+U (Mac) or Ctrl+U (Win/Linux) β†’ see raw HTML
2. Sources tab in DevTools β†’ see all .js files
3. Search fetch( in global search (Cmd+Shift+F) β†’ see ALL possible network calls. None point to our servers for analyses.
