TachiyomiSY is not available on mainstream app stores, so users must rely on verified sources to download and install the application safely. This section provides a complete overview of the secure installation process, including where to obtain the APK file, how to install it on Android devices, and which permissions are required.
Secure APK Sources
To maintain device security and ensure functionality, it is important to download the TachiyomiSY APK only from reputable and recognized sources. These include official GitHub repositories or well-maintained websites dedicated to Tachiyomi forks. Using unofficial or unverified APKs can lead to compromised privacy or malware infections.

Permissions and Security Settings
TachiyomiSY requires limited permissions to operate effectively. These may include access to storage (for saving downloads and backups) and network access (to fetch content from online sources). Users are advised to review permission requests during installation and grant only those necessary for core functions.
For added safety, users should consider using a mobile antivirus or monitoring tool, especially when installing third-party extensions. Maintaining regular backups and avoiding suspicious sources will help protect both data and device integrity.
Setting Up Extensions
TachiyomiSY offers a flexible and powerful extension system that allows users to access a wide range of manga and anime sources directly from within the app. Properly setting up extensions ensures a seamless reading and streaming experience.
Navigating the Extensions Tab
Within the app interface, the extensions tab serves as the central hub for discovering and managing content sources. Users can access it through the main menu. This section lists available extensions categorized by region, language, and content type, enabling users to explore options based on their preferences.
Installing Manga and Anime Sources
To begin, users can scroll through the available extensions and tap on any preferred source to install it. Installation is quick and typically completed with one tap. Once added, these sources appear in the browse section, allowing users to search and stream content from each extension. Manga extensions provide access to chapter listings and metadata, while video extensions support anime streaming directly or through external video players.
Troubleshooting Common Extension Issues
Occasionally, users may face issues such as failed loading, outdated sources, or missing chapters. Most problems are resolved by updating the affected extension or clearing the app’s cache. If an extension no longer works, it is likely the source has changed its structure or been discontinued. Users are encouraged to check for alternative sources or wait for community updates. Managing extensions through regular updates and removal of inactive ones helps maintain app performance and usability.
Privacy and Security Considerations

Handling Third-Party Extensions
TachiyomiSY allows the integration of various third-party extensions that provide access to manga and anime content from different sources. While this flexibility is a core feature, users must exercise caution when installing or using these extensions. Not all sources guarantee secure connections or verified content, and some may compromise user data or device security.It is recommended to install extensions only from trusted repositories and review user feedback when possible. Users should avoid downloading unofficial APKs or modified extensions from unverified websites, as these can contain malicious code or spyware.
Use of VPNs and Ad Blockers
To enhance privacy and reduce exposure to potentially intrusive ads or data tracking, many users opt for virtual private networks (VPNs) and ad-blockers while using TachiyomiSY. A VPN can protect user identity and location, particularly when accessing sources that are region-restricted or of questionable legality. Ad blockers may improve the user experience by preventing unwanted content or malicious scripts from loading within certain extensions. Both tools add an extra layer of protection when interacting with unknown or unverified sources.
Content Legality and Developer Responsibility
TachiyomiSY, like its base version, does not host any content itself. The application merely serves as a framework to aggregate and display content from external sources through user-installed extensions. The developers explicitly distance themselves from any pirated or unauthorized material accessed through third-party plugins. Users are solely responsible for the sources they connect with and the content they view. It is advised to comply with local copyright laws and respect the rights of original creators.
App Permissions
TachiyomiSY operates without requiring sensitive device permissions, which enhances local data privacy. It does not request access to contacts, messages, or location, and all user data — including reading history, library settings, and downloads — is stored locally on the device. This approach ensures that user activity remains private and is not transmitted to any external server unless the user explicitly chooses to back up or sync their data. This local-first design aligns with privacy-conscious development practices and gives users full control over their usage data.
