Privacy Policy for Autofill AI Ninja
Last updated: August 11, 2026
This Privacy Policy describes how the Autofill AI Ninja Chrome extension (“the Extension”) handles information when you install and use it. The Extension is designed for QA and development workflows that fill web forms with synthetic test data.
Data collection and usage
Autofill AI Ninja reads webpage structure (website content such as form labels, field types, placeholders, and related UI text) and may use user-provided candidate profiles or custom instructions (which can include personally identifiable information) strictly to perform local, browser-based form filling on pages you choose to fill.
The Extension does not browse the web on its own. Filling starts only from an explicit user action (side panel, context menu, or keyboard shortcut), except for short-lived same-tab resume after a multi-step navigation you already started.
Data storage
Settings, optional custom instructions, fill preferences, and API keys are stored
locally on your device using Chrome extension storage
(chrome.storage.local and, when applicable,
chrome.storage.session). You may optionally encrypt stored API keys at rest
with a passphrase.
We do not operate external servers that collect, store, analyze, or sell your profiles, form contents, or API keys.
Third-party processing
If you configure an LLM provider and use a fill mode that calls the model, field labels, limited form context, and related prompt content are sent securely over HTTPS directly from your browser to the provider you selected (for example OpenAI, Anthropic, Google AI Studio, xAI, Groq, OpenRouter, or Cerebras), solely to generate autofill values for that request.
- You supply and control your own API key.
- Only the selected provider is contacted.
- Heuristics-only mode does not send form contents to any LLM provider.
- Third-party providers process data under their own privacy policies and terms. Review those policies for the vendor you configure.
Data sharing
We do not sell, rent, or trade user data to third parties, data brokers, or advertising networks. Form-related content leaves your device only when you enable LLM filling and only to the API endpoint you configured.
Sensitive fields
The Extension can optionally skip password and payment-related fields
(excludeSensitiveFields). Even when those options are off, you remain
responsible for not submitting real production credentials or payment data into test
workflows.
Chrome permissions
Host and storage permissions exist so the Extension can inject into pages you fill, keep settings and keys on device, and call your chosen provider’s HTTPS API. They are not used to track browsing history for advertising or analytics.
Changes to this policy
We may update this Privacy Policy as the Extension evolves. The “Last updated” date at the top of this page will change when material revisions are published.
