This extension collects no data, transmits no data, and makes no network requests of any kind. Every journal lookup is answered from data files bundled inside the extension package itself.
In one paragraph
Scholar Metrics reads the journal name printed under each result on Google Scholar, looks it up in a list of journals stored inside the extension, and draws a badge. That is the whole of it. Nothing is uploaded, because the extension has no ability to make network requests at all. The only things written to your computer are your own settings and a list of journal names already looked up.
Data we do not collect
Using the categories defined by the Chrome Web Store, the extension collects none of the following:
| Data type | Collected? |
|---|---|
| Personally identifiable information (name, address, email, age, identification number) | No |
| Health information | No |
| Financial and payment information | No |
| Authentication information (passwords, credentials, security questions, PINs) | No |
| Personal communications (emails, texts, chat messages) | No |
| Location (region, IP address, GPS coordinates) | No |
| Web history | No |
| User activity (clicks, mouse position, scroll, keystroke logging) | No |
| Website content (text, images, sounds, files, hyperlinks) | No |
What is stored on your device
The extension requests one permission, storage, and uses it for
two things. Neither leaves your device, and neither is accessible to the
developer.
-
Your settings. Which ranking system leads each badge,
whether the strip is full or compact, whether shortened venue names are
matched at all, and which Google Scholar pages the extension runs on. These are kept in
chrome.storage.sync, so Chrome mirrors them between your own signed-in devices under your own Google account — the same mechanism used for bookmarks. They are never sent anywhere else. -
A local lookup cache. Journal names already resolved are
kept in
chrome.storage.localso that revisiting a page is instant. This cache contains journal titles and their index status only. It never contains article titles, author names, search queries, URLs, or anything identifying you. You can erase it at any time using the Clear cache button in the extension popup, or by removing the extension. Entries are also discarded automatically whenever the extension is updated or its journal data is rebuilt, so a stale answer is never served after a correction.
Which pages the extension can access
The extension runs only on Google Scholar addresses —
scholar.google.com and its country domains such as
scholar.google.com.vn. On those pages it reads the venue name
printed beneath each result so it can look that journal up in its bundled
data, and it inserts its own badges into the page.
It declares no host permissions for any other website, so it is technically incapable of reading or modifying any other page you visit. It does not read your search queries, your account, or your browsing history.
No network requests, no third parties
The extension contains no analytics, no telemetry, no trackers, no advertising, and no remotely hosted code. It does not contact the developer's servers, and it does not contact SCImago, Clarivate, Google, or any other third party. There is no networking code in the extension at all.
This can be verified from the extension's manifest, which declares the
storage permission and nothing else, with no host permissions
beyond Google Scholar itself.
Data sharing, sale, and use
Because no user data is collected, no user data is sold or transferred to third parties. No data is used or transferred for purposes unrelated to the extension's single purpose, and none is used or transferred to determine creditworthiness or for lending purposes.
Children
The extension is an academic research tool. It has no accounts, no sign-in, and no data collection, and it is not directed at children.
Changes to this policy
If this policy changes, the revised version will be published on this page with an updated date. Any change that introduced data collection would require a new extension version and your explicit consent to the new permissions before it could take effect.
