Introduction

After installing a plethora of apps on mobile devices, permissions for location, contacts, photo albums, microphones, and other functions often remain in an “always allow” state or have not been reviewed for a long time. Furthermore, system settings and privacy options on various social platforms are scattered across different menus. When attempting to tighten security based on the “Principle of Least Privilege,” it is often difficult to determine which items to disable or how to navigate the paths.

The following is an introduction to the community Skill on SkillHub: “Privacy Protection Settings” (@user_70c2f807/privacy-protection-settings). It organizes system-level settings, app permissions, social platform hardening, and periodic reviews into actionable steps and output templates. It is suitable for delegating to Agents like Cursor that support Skills, allowing them to proceed item by item based on your device model and specific concerns. It should be noted that this Skill targets personal terminals and common apps, and does not involve enterprise compliance or GDPR-type solutions.

What is This

“Privacy Protection Settings” is an Agent Skill originating from the SkillHub community (community), published by user_70c2f807. The current version is 1.0.0, categorized under it-ops-security, and tagged with requires_api_key=false (meaning installation and use do not depend on an additional API Key).

The Skill is positioned for use when users wish to reduce privacy leakage on their phones and apps, or understand privacy settings and the principle of least privilege across various platforms. The official page and coordinates are as follows:

  • SkillHub Display Page: https://www.skillhub.cn/skills/user_70c2f807/privacy-protection-settings
  • Installation Coordinates: @user_70c2f807/privacy-protection-settings

Core Features

The following content is derived from the Skill’s SKILL.md description and outlines the capability boundaries the Agent should follow once triggered.

  1. System-Level Privacy Settings: Guides adjustments to system privacy options (specific paths vary by iOS/Android and version).
  2. App Permission Review & Optimization: Compares current authorizations against the principle of least privilege and provides recommendations to disable or downgrade permissions (e.g., changing location access to “While Using”).
  3. Social Platform Privacy Hardening: Explains actionable privacy settings on various social platforms.
  4. Leak Detection & Remediation: Provides clues and inspection ideas in the FAQ (e.g., checking if an email is in a public leak database).
  5. Browser & Search Privacy: Includes protection recommendations for browsing and searching.
  6. Structured Output: Outputs a permission table, least privilege principles, system settings, social hardening tables, and periodic checklists according to fixed templates.

The Skill explicitly lists the following limitations: paths may vary across different systems and app versions; convenience and security must be balanced; digital footprints cannot be completely eliminated; and privacy policies on various platforms may change.

Installation & Activation

Install SkillHub CLI (If not already installed)

First, verify if skillhub is already on your machine:

command -v skillhub && skillhub --version

If not installed, you can follow the official SkillHub installation documentation to perform a full installation or CLI-only installation:

curl -fsSL https://skillhub-1388575217.cos.ap-guangzhou.myqcloud.com/install/install.sh | bash

curl -fsSL https://skillhub-1388575217.cos.ap-guangzhou.myqcloud.com/install/install.sh | bash -s -- --cli-only

Instructions and full details are available at: https://skillhub.cn/install/skillhub.md

Install This Skill

When installing, you must use --dir to point to the current Agent’s skills directory; otherwise, it defaults to ./skills/ and may not be recognized. Using Cursor as an example, the common path is ~/.cursor/skills/:

skillhub install @user_70c2f807/privacy-protection-settings --dir ~/.cursor/skills/

Paths for other clients (excerpted from the official installation documentation; select one based on your actual Agent):

  • Claude Code: ~/.claude/skills/
  • Codex: ~/.codex/skills/ or .agents/skills/ under the project
  • Windsurf: ~/.codeium/windsurf/skills/ or .windsurf/skills/ in the project

Alternatively, you can ask the AI to install it via official prompts: According to https://skillhub.cn/install/skillhub.md, install @user_70c2f807/privacy-protection-settings.

If the Agent does not automatically load the new Skill after installation, restart or reopen the session according to your client’s instructions.

Typical Usage

The Skill suggests establishing the environment first in the conversation before generating a targeted plan. The official “Quick Start” example flow is as follows:

  1. State the mobile operating system (iOS / Android).
  2. Describe the privacy issues you are most concerned about (e.g., location, contacts, photos).
  3. List frequently used apps.
  4. The Agent outputs a plan based on the execution steps within the Skill.

The execution steps are fixed at six stages within the Skill: Permission Review → Least Privilege → System Settings → Social Hardening → Browsing Security → Periodic Review.

The expected output structure includes an “APP Permission Review” table, “Principle of Least Privilege” items, “System Settings” path suggestions, a “Social Platform Hardening” table, and a “Periodic Checklist” (e.g., checking permissions monthly, cleaning up unused apps quarterly, checking for anomalous logins, etc.). The FAQ also summarizes priority permission types to restrict (location, contacts, microphone, camera, SMS, etc.) and explains the limited effectiveness of disabling ad tracking.

Users can simply say: “Help me use ‘Privacy Protection Settings’,” and then provide the above information to initiate the process.

Scenarios & Precautions

Who is it for

  • Individual users who want to systematically sort out mobile and app permissions and tighten them according to the principle of least privilege.
  • Those who need a checklist of privacy settings for social platforms and browsers and are willing to perform periodic reviews.
  • Users operating in Agent environments that have configured Skills directories, such as Cursor, Claude Code, Codex, etc.

What it is not for

The Skill explicitly states it is not applicable for: Enterprise data protection and compliance (including GDPR, etc.), privacy protection technology R&D, app privacy compliance auditing, or government surveillance and forensic technology.

Usage Precautions

  • If an app becomes unusable after a permission is turned off, the Skill suggests evaluating whether the app is truly needed rather than simply restoring all permissions.
  • Since paths change with device models and versions, the Agent provides principles and templates; you must verify menu names in the actual device settings when implementing them.
  • Privacy recommendations are based on public best practices; the Skill states it does not collect user device or app information, nor does it make commercial recommendations for specific apps.

Conclusion

“Privacy Protection Settings” translates permission review, system and social hardening, browsing privacy, and periodic maintenance on personal terminals into Agent-executable steps and output formats, making it suitable as a collaborative template for daily privacy self-checks.
