Privacy Policy

Last updated: April 2026

To use Google Drive storage, you must sign in with a Google account. The following permissions are requested:

• openid / profile — Used to obtain your display name, profile picture, and Google account ID (for header display and sign-in management).
• Google Drive (drive.file) — Access only to files created or opened by this app. No access to your entire Google Drive.

The following data is obtained from your Google account:

• Display name
• Profile picture URL
• Google account ID

For sign-in management, the database stores your display name, profile image URL, and Google account ID.

Document data (diagram/text editing content) is stored only in the following locations:

• Local storage: Saved in your browser on this device (it stays on the device and is not sent to our server).
• Google Drive storage: Saved as a file within your own Google Drive account. Our server does not retain the file.

When you first use image background removal or magic eraser, the browser downloads the required ONNX model from Hugging Face. Image data and document contents are not sent to the model host; processing runs in the browser.

To improve app quality, runtime errors that occur in your browser (exceptions and unhandled promise rejections) may be sent to server logs.

• Data sent: error message, stack trace, page URL, browser information, and event timestamp
• Purpose: detection, reproduction, and remediation of failures. Not used for advertising purposes.

We use Google Analytics to understand usage and improve quality.

• Data sent: page URL, browser and device information, referrer, interaction events, event timestamp, and similar usage data
• For runtime errors in the browser, we may send only the error type, error name, and page path to Google Analytics for trend analysis. Error messages and stack traces are not sent.
• Data not sent: document contents, diagram/text editing contents, Google Drive file contents, file names, and file IDs
• Purpose: usage analysis, feature improvement, and understanding defects or usability issues.

We do not sell or share collected data with third parties.
