SideZerothe honest AI sidebar

Verify the wiring

Every AI extension says it respects your privacy. Ours is the rare claim you can check yourself — in about 60 seconds, with tools already built into Chrome.

The claim: your API keys and your conversations travel from your browser directly to the AI provider you chose — and nowhere else. SideZero has no server in the middle. Nothing is proxied, logged, mined, or phoned home. Keys live in your browser's local extension storage and never leave it except as the authorization header of a request to that provider.

Watch the traffic yourself

Open the SideZero side panel, then go to chrome://extensions and switch Developer mode on (top right).
On the SideZero card, click Inspect views → sidepanel.html. A DevTools window opens — this is the extension's own traffic, nothing else mixed in.
Pick the Network tab in that DevTools window.
Back in the panel: send a message, summarize a page, generate an image — use anything.
Read the Domain column. Every request goes to the provider whose key you added. Click any request → Headers to see exactly what was sent, and to whom.

The complete list of domains

This is every network destination in the extension. Not the highlights — the whole list.

Domain	What it's for	When
`api.anthropic.com`	Claude chat, web search, model list	Only with your Anthropic key
`api.openai.com`	GPT chat, images, deep research, voice, model list	Only with your OpenAI key
`generativelanguage.googleapis.com`	Gemini chat, search, images, deep research, voice, model list	Only with your Google key
`openrouter.ai`	OpenRouter chat + live model prices	Only with your OpenRouter key
`127.0.0.1:11434`	Ollama — local models on your own machine	Never leaves your computer at all
`cdn.currency.wiki`	Live exchange rates for the price-conversion feature — a free feed we run ourselves. The request carries no key, no page content, no identifiers, and is cached for an hour.	Only when you convert prices

That's the whole list. A request to any other domain would be a bug — we'd genuinely like to hear about it: [email protected].

What you will never see

No calls to sidezero.app. The extension never phones home. You only land on our site when you click a "get a key" link in Settings (a plain redirect), or when Chrome itself opens our feedback page after an uninstall — carrying nothing but your browser type and the extension version, never an identifier.
No analytics or telemetry domains. There is no tracking library in the extension. We don't know who you are, what you browse, or what you asked.
No error reporting. Diagnostics stay on your device; the Support card lets you copy a scrubbed debug summary and email it — or not. Key-shaped strings are removed from it before it's even written to disk.
No key sync. Keys are stored with chrome.storage.local — the variant that never syncs to your Google account or other machines.

Why this works as proof

A browser extension can't hide its traffic from its own browser. DevTools sits below the extension, not beside it — if SideZero called anywhere else, it would appear in that Network tab, timestamped, with the payload attached. That's why we'd rather show you the wiring than ask you to trust a policy page.
