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)
Open Alpha Terminal
Go to alpha-terminal.app and click Get started. You can enter a free API key (GitHub Models, Cerebrasβ¦) or click "Access without a key" to explore.
Open your browser DevTools
Keyboard shortcut:
- Mac:
Cmd + Option + I(Chrome/Edge/Firefox) orCmd + Option + C(Safari, after enabling "Develop menu" in Preferences) - Windows / Linux:
F12orCtrl + Shift + I
Go to the Network tab. Tick "Preserve log" at the top.
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.).
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.
Observe the result
Throughout the analysis, the panel filtered on alpha-terminal.app should show:
π 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
| Data | Destination | Our server? |
|---|---|---|
| Analyzed ticker (AAPL, BTCβ¦) | Chosen AI API | β No |
| Your prompts | Chosen AI API | β No |
| Your portfolio (Wealth) | Browser localStorage | β No |
| Your RAG documents | Browser IndexedDB | β No |
| Financial data (prices, financials) | FMP / Polygon / Yahoo / etc. | β No |
| License activation | api.lemonsqueezy.com | β No (their server) |
| Anonymous analytics (page visits) | plausible.io | β No Β· cookieless Β· IP anonymized |
Technical architecture: why it's possible
Alpha has no backend for analyses. It's a deliberate design choice. Here's how each component works:
api.anthropic.com, api.openai.com, etc. via fetch() in your browser. No middleware on our side.IndexedDB + localStorage. No server DB.AES-GCM-256 with your passphrase (PBKDF2 100k iter). The encrypted vault stays local. We never see it.What we CAN'T do (even if we wanted to)
- Read your portfolio or positions β they never left your browser
- Read your analysis prompts β they go directly to the AI provider
- Read your API keys β they're encrypted with your passphrase
- Sell your activity to advertisers β we don't have the data
- Hand over your analyses (even under legal subpoena) β we never had them
Open code = open audit
You can inspect the frontend source code directly in your browser:
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.
Comparison with cloud competitors
| Platform | Where does your data go? |
|---|---|
| Alpha Terminal | Stays on your device |
| Bloomberg Terminal | Bloomberg cloud + government access (Patriot Act) |
| Koyfin | Koyfin cloud (USA) |
| Seeking Alpha | Cloud + ad monetization |
| ChatGPT (personal analysis) | OpenAI cloud + used for training (unless opt-out) |
| Stock Rover | Stock Rover cloud |
