ProofPilot — Privacy Policy

Last updated: February 11, 2026

Overview

ProofPilot is a browser extension that proofreads selected text using AI. Your privacy is important to us. This policy explains what data the extension accesses, how it is used, and what is stored.

Data collected and transmitted

When you right-click selected text and choose ProofPilot, the following data is sent to your chosen AI provider:

• Selected text — the text you highlighted is sent to the API for proofreading.
• API key — your personal API key is included in the request to authenticate with the provider.

The text is sent directly from your browser to the AI provider's API. ProofPilot does not operate any servers and does not relay, log, or store your text.

Third-party API providers

Depending on your configuration, your text is sent to one of:

• Anthropic (api.anthropic.com) — Anthropic Privacy Policy
• OpenAI (api.openai.com) — OpenAI Privacy Policy

How these providers handle your data is governed by their respective privacy policies and API terms of service. When using the API (as opposed to consumer products), both providers state that API inputs are not used to train models by default.

Data stored locally

The following settings are stored in your browser using chrome.storage.sync:

• Selected AI provider (Anthropic or OpenAI)
• Selected model ID
• Language preference
• API keys (one per provider)

This data stays in your browser and is synced via your Chrome profile if sync is enabled. It is never transmitted to ProofPilot or any third party other than the API providers listed above.

Permissions used

• contextMenus — to add the "ProofPilot" item to the right-click menu.
• activeTab — to read the selected text from the current page and display the correction overlay.
• storage — to save your settings (provider, model, language, API keys) locally in the browser.
• host_permissions: api.anthropic.com, api.openai.com — to send proofreading requests to the AI APIs.

Data not collected

ProofPilot does not:

• Collect analytics or usage data
• Track browsing history or behavior
• Store or log the text you proofread
• Transmit data to any server other than the chosen API provider
• Use cookies
• Display advertisements

Children's privacy

ProofPilot is not directed at children under 13 and does not knowingly collect personal data from children.
