Privacy Policy for Fillo

Last Updated: June 18, 2025

Overview

Fillo is a Chrome extension designed to help developers by intelligently filling form fields on localhost development sites using AI language models. This privacy policy explains how Fillo collects, uses, and protects your data.

Data Collection and Usage

What Data We Collect

1. API Keys and Configuration
   • API keys for language model providers (OpenAI, Anthropic, Google, Ollama)
   • Provider settings and model preferences
   • Creativity level preferences
   • General extension settings
2. Form Field Data (Localhost Only)
   • Form field types and labels detected on localhost sites
   • Generated content for caching purposes
   • Page context (titles, meta tags) from localhost sites only
3. Usage Data
   • Cache hit/miss statistics
   • Error logs (no personal data included)
   • Performance metrics

How We Use Your Data

1. Primary Functions
   • Generate contextually appropriate content for form fields
   • Cache responses to reduce API calls and improve performance
   • Provide personalized AI-generated content based on your creativity preferences
2. Performance Optimization
   • Store generated content locally to avoid duplicate API calls
   • Monitor extension performance to identify and fix issues

Data Storage

1. Local Storage Only
   • All data is stored locally on your device using Chrome's storage API
   • API keys are encrypted before storage
   • No data is transmitted to Fillo's servers
2. Temporary Cache
   • Generated content is cached locally with expiration times
   • Cache can be manually cleared through the extension settings

Data Sharing

Third-Party Services

Fillo integrates with the following AI providers when you configure and use them:

1. OpenAI - When using OpenAI models, your prompts are sent to OpenAI's API
2. Anthropic - When using Claude models, your prompts are sent to Anthropic's API
3. Google - When using Gemini models, your prompts are sent to Google's API
4. Ollama - When using local Ollama models, data stays on your local machine

Important: Your API keys and generated content are only shared with the specific AI provider you choose to use for each request.

No Data Sales or Marketing

• Fillo does not sell your data to third parties
• Fillo does not use your data for advertising or marketing purposes
• Fillo does not share your data with any parties other than the AI providers you explicitly configure

Security Measures

1. API Key Protection
   • API keys are encrypted using Chrome's storage encryption
   • Keys are never logged or transmitted outside of API calls
   • Keys are automatically cleared if the extension is uninstalled
2. Localhost Restriction
   • Extension only operates on localhost development sites
   • No data collection from production or public websites
   • Hostname validation prevents accidental activation on non-localhost sites
3. Minimal Permissions
   • Extension requests only necessary Chrome permissions
   • No access to browsing history or personal files
   • No network access beyond configured AI provider APIs
