Manga Translator Z
Effective date: April 4, 2026
Manga Translator Z ("the Extension") is a Chrome extension that translates manga, manhwa, and manhua images using AI. This policy explains what data we collect, how we use it, and how different backend modes affect your privacy.
Summary
| Data | Purpose | Stored Where |
|---|---|---|
| Anonymous install ID (UUID) | Identify installations for quota tracking | Locally via chrome.storage; sent to hosted server only |
| Image hashes (SHA-256) | Deduplication to avoid re-translating identical images | Locally via chrome.storage |
| User settings and preferences | Persist your configuration choices | Locally via chrome.storage |
| Weekly page count | Enforce free-tier quota (hosted mode only) | Server-side, keyed to anonymous install ID |
When you use the hosted translation server (the default), the following data is sent to our server for processing:
Image data is processed in memory for translation and is not stored permanently on our servers. Translated results are returned to your browser and discarded server-side after delivery.
Weekly page count is tracked anonymously to enforce the free-tier limit of 40 hosted pages per week. This counter resets weekly and is associated only with your anonymous install ID, not with any personal information.
When you connect the Extension to a local server running on your own machine, all image data and translation processing stays entirely on your device. No data is sent to our servers.
When using the Ollama backend, images are sent to the Ollama instance running at the URL you configure (typically on your local machine). No data is sent to our servers. Your data handling is governed by your own Ollama setup.
When using OpenAI with your own API key, images are sent directly to the OpenAI API using your key. No data passes through our servers. Your data handling is governed by OpenAI's privacy policy.
All locally stored data (install ID, image hashes, settings) resides in Chrome's built-in chrome.storage.local API, which is sandboxed to the Extension and not accessible by websites or other extensions.
Communication with the hosted server is encrypted via HTTPS. Image data transmitted for translation is processed in memory and not written to persistent storage on our servers.
Depending on the backend mode you choose, your data may be processed by:
The Extension does not integrate any third-party analytics, advertising, or tracking services.
The Extension is not directed at children under 13. We do not knowingly collect any personal data from anyone, including children.
We may update this policy to reflect changes in the Extension's functionality. Material changes will be communicated through the Extension's update notes on the Chrome Web Store. The effective date at the top of this page will be updated accordingly.
