Privacy Policy

Last updated: June 9, 2026

Yansio is a browser extension for English writing assistance on web pages. It works on editable web surfaces such as textareas, supported text-like inputs, and contenteditable editors. The extension only processes text when the user explicitly triggers rewriting, correction, or translation.

What data may be processed

• Selected text.
• Nearby editor context required to preserve tone and intent.
• Current page URL and page title inside extracted context metadata.
• User-entered model configuration, including API endpoint and API key.
• Local usage statistics such as token counts and request duration.

How the data is used

• Selected text and necessary context are sent to the AI provider configured by the user in order to return a rewrite, correction, or translation result.
• API keys are stored locally in browser extension storage so the user does not need to re-enter them.
• Token counts and timing data are stored locally for statistics.
• Call history is disabled by default. If the user turns off privacy mode, recent request input, output, and context may be stored locally for history display.

Data sharing

• User text is transmitted only to the model provider selected and configured by the user.
• The extension developer does not currently route requests through a separate developer-owned relay server.
• Data is not sold.

Local storage

• Model configurations.
• Active model selection.
• Domain rules.
• Privacy mode preference.
• Token usage statistics.
• Optional call history if the user turns off privacy mode.

User controls

• Choose which model provider to use.
• Configure or remove stored API keys.
• Control which sites and site rules are active.
• Keep privacy mode enabled so new call history is not stored.
• Clear locally stored history.
• Export or import local configuration backups.
