Privacy policy

Updated: 13 September 2026

This page describes how I, Andrey Udovichenko, handle data on this portfolio site and in the internal n8n-backup app, which connects to Google through OAuth.

Google Drive / n8n-backup. The app requests Google Drive access only to upload backup archives from my server into a folder of my (or an explicitly authorized) Google account. Google data is not sold, not used for ads, and not shared with third parties. Access can be revoked at any time: Google Account → Third-party apps.

2. Portfolio site

Public pages (the home page and this policy) do not require registration and do not collect visitor accounts. There are no forms with personal data on the site. Clicks through to Telegram and email happen on those services’ side.

The host and the browser may process technical data (IP, user-agent, request time) in server logs — only to run the site and for diagnostics.

3. The n8n-backup app and Google data

n8n-backup is an internal self-hosted automation app. It uses Google OAuth to upload a backup file to Google Drive on your behalf.

Google data requested: Google Drive access needed to create or update a backup file in the chosen folder.
How it is used: only to write the backup archive (and file metadata: name, size, parent folder).
Where it is stored: the file ends up in your Google Drive. Access tokens are stored in credentials on my n8n server and are not published.
Sharing: Google user data is not sold and is not shared with third-party services other than the Google Drive API itself.
Retention: while the app stays connected. After access is revoked, new uploads are impossible; files already on Drive stay yours and can be deleted manually.

Use of Google data is limited to the practices on this page and complies with the Google API Services User Data Policy, including Limited Use.

4. English summary (for Google OAuth)

The app n8n-backup is a private backup workflow. After you sign in with Google, it uploads backup archive files from the operator’s server to the Google Drive account that granted access. Google user data is used only to store those backups. It is not sold, not used for ads, and not shared with third parties. You may revoke access at any time in your Google Account.
