Privacy Policy
This Policy sets out how user information is handled by videoconverter.tokyo (the "Service"), as follows.
1. Login and Account Creation via Google Account
The Service provides login and account creation using a Google account. When you use Google Sign-In, the following information is obtained from Google.
- Google account identifier (Subject ID)
- Email address
- Display name (account name)
When creating a new account, the username you enter is also stored in the database alongside this information.
This information is used solely to identify you and to keep you logged in.
2. Recording of Operation Logs
The Service records logs of user operations for service improvement, fraud prevention, and troubleshooting. The information recorded is as follows.
- IP address
- User-Agent (browser, OS, and similar information)
- Device information such as device type and screen width, time zone, and language settings
- Username, the type of operation (page view, login, video selection, conversion start, download, etc.) and the time of the operation
- Values of some input fields, such as the trim range and output size
- A hashed identifier issued solely to group related actions together (not the actual session ID used for login authentication)
We never record secrets such as passwords, OAuth authorization codes, or access tokens in the operation log. The identifier we log is a separate, log-only ID used to group related actions together — it is not the real session ID used for login.
We also never record video/audio content, video file names, or your Google password.
3. Handling of Video Data
Uploaded videos are temporarily stored on the server solely for trimming and resizing. Converted videos are temporarily stored for download purposes.
Uploaded and converted videos are, in principle, automatically deleted within 1 hour of creation. The Service does not make videos public to third parties or use them for any purpose other than processing.
4. Security
The Service takes reasonable security measures, but does not fully guarantee the safety of transmitted or stored data.
5. Third-Party Services Used
- Google OAuth 2.0 (login and account creation via Google account)
- Google AdSense (third-party advertising service)
- Google Analytics (usage analytics service)

9. Advertising
This Service uses Google AdSense as an advertising service.
Third-party vendors, including Google, may use cookies and similar technologies to serve ads based on a user's prior visits to this Service or other websites.
As a result, users may see personalized ads based on their interests.
If you would prefer that Google not use advertising cookies, you can disable personalized advertising through Google Ads Settings.
For advertising cookies used by third-party vendors other than Google, you can opt out collectively through the opt-out tool at aboutads.info.
For details on how Google uses information obtained from sites like this one, please see how Google uses information.
10. Use of Google Analytics
This Service uses Google Analytics (Google Analytics 4) to analyze how the Service is used.
Google Analytics uses cookies to collect data such as page views and device/browser details. Your IP address is used momentarily to estimate your approximate location, but is not stored by Google Analytics 4.
If you would prefer that Google Analytics not collect your data, you can opt out by installing the Google Analytics Opt-out Browser Add-on.
