Privacy Policy

Last updated: June 2026

Sylvia ("the Extension") is a Chrome extension that helps you manage your Gmail inbox using AI. This policy explains what data we access, how we use it, and what we never do with it.

1. What data we access

To function, Sylvia requests access to your Gmail account via Google's official APIs. This may include:

Email metadata (sender, subject, date, labels)
Email content, when required to carry out a task you explicitly request
Your Google account email address (for authentication only)

2. How we use your data

All data accessed through Gmail is used exclusively to perform the actions you request within the Extension (search, filter, label, summarise). Specifically:

Email content may be sent to an AI model (OpenAI, Google Gemini, or Azure OpenAI — configured by you) to generate responses.
Requests are routed through Sylvia's backend server, hosted in Germany (EU), solely to forward your queries to the AI provider. No email data is stored on this server.
No email data is used for advertising, analytics, or any purpose beyond fulfilling your request.

3. What we never do

We do not sell your data to third parties.
We do not store your emails or personal information.
We do not use your data to train AI models.
We do not share your data with anyone except the AI provider you configure.

4. Google API Services

Sylvia's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

5. Third-party AI providers

When you configure an AI provider (OpenAI, Gemini, Azure), your requests are processed according to that provider's privacy policy. Sylvia does not control how those providers handle data once it is transmitted.

6. Data retention

Sylvia stores only your API keys and preferences locally in your browser using Chrome's storage API. This data never leaves your device.

Sylvia's backend server is located in Germany (EU). It acts solely as a relay between your browser and the AI provider you configure, and retains no email data, logs, or personal information.

7. Children's privacy

Sylvia is not directed at children under 13 and does not knowingly collect data from them.

8. Changes to this policy

We may update this policy. The "last updated" date at the top will reflect any changes.
