Privacy Policy for Bilibili Follow Cleaner

Last updated: [April 2026]

Bilibili Follow Cleaner (“the extension”) helps users review and clean their Bilibili follow list by identifying followed accounts that have been inactive for a long time and allowing users to manually confirm unfollow actions.

1. What this extension does

The extension is designed to work on Bilibili follow-related pages and official Bilibili API endpoints that are necessary for the extension’s core follow-cleaning workflow.

Its core functions include:

reading the user’s Bilibili follow-list context
checking recent activity information for followed accounts
displaying inactive followed accounts inside the extension UI
allowing the user to manually select accounts
sending unfollow requests only after the user explicitly confirms the action

2. What data the extension handles

The extension may handle the following categories of data:

a. Website content

The extension reads limited content from Bilibili pages and official Bilibili API responses that is necessary to provide its core functionality, such as:

followed account identifiers
followed account display information shown on Bilibili pages
recent activity or update timing related to followed accounts
page context needed to locate and manage the user’s follow list

b. Extension local data

The extension may store the following data locally on the user’s device using Chrome extension storage:

user settings and preferences
scan progress
scan results
locally cached scanned-account data

3. How the data is used

The extension uses data only for the following purposes:

to scan the user’s Bilibili follow list
to identify followed accounts that appear inactive based on the extension’s rules
to present the scan results to the user
to let the user manually confirm cleanup actions
to resume interrupted scans and avoid unnecessary repeated scanning

The extension does not sell user data.

The extension does not share user data with advertisers or data brokers.

The extension does not send handled data to the developer’s own servers.

The extension communicates only with Bilibili pages and official Bilibili API endpoints as required for the extension’s user-facing functionality.

5. User control

The user controls when the extension runs.

The extension performs scanning only when the user uses the extension.

Unfollow actions are sent only after the user manually selects accounts and explicitly confirms the action.

Users can stop using the extension at any time by disabling or uninstalling it. Users can also clear extension data through the browser’s extension storage controls by removing the extension.

6. Data retention

Locally stored extension data remains on the user’s device until it is overwritten, cleared by the user, or removed when the extension is uninstalled, subject to browser behavior.

7. Security

The current version of the extension is designed so that executable extension logic is packaged with the extension itself. It does not load or execute remotely hosted code.

8. Third-party services

This extension depends on Bilibili pages and official Bilibili API endpoints to provide its functionality. Use of Bilibili is also subject to Bilibili’s own terms and privacy practices.

9. Children’s privacy

This extension is not specifically directed to children.

10. Changes to this policy

This Privacy Policy may be updated from time to time. If the extension’s data practices change, the policy will be updated accordingly and the revised version will be posted at this page.
