Разрешения на доступ обычных чекеров почты: http://inbox.google.com/* http://mail.google.com/* https://inbox.google.com/* https://mail.google.com/* Разрешение на доступ этого чекера: *://*.google.com/* То есть, если я правильно понимаю, расширению «Google Mail Checker» предоставлен доступ не только к почте, а ко всему гугл-аккаунту. К тому же, издатель не предоставил никакой информации о сборе и использовании личных данных. Возможно, я в чём-то заблуждаюсь. В таком случае буду рад, если меня поправят.

Beim Öffnen des Chrome Browsers "hängt" die Erweiterung neuerdings, soll heißen diese ist grau und mit einem Fragezeichen versehen. Erst wenn man Gmail öffnet, aktualisiert diese sich.

Lukas Krampitz2021年5月13日

A very nice, very simple extension. It's been working great for years now and I am very pleased with it.

AI product read

Displays the number of unread Gmail messages as a badge on the browser toolbar icon and provides quick access to Gmail inbox

Allows users to quickly check their Gmail unread count without opening Gmail, saving time by showing at-a-glance email status in the browser toolbar

Extension installs → polls Gmail Atom feed using browser cookies → displays unread count as badge text on toolbar icon → user clicks icon to open/focus Gmail inbox. Polling repeats every 5-60 minutes with exponential backoff on failures.

Target users: Gmail users who want quick visual notification of unread emails / Users who prefer toolbar badge notifications over checking Gmail tab directly

Cannot confirm whether the Gmail Atom feed (/feed/atom) is still actively supported by Google as a functional API endpoint in 2024

Monetization

No paid features detected

The extension contains no payment logic, no subscription checks, no premium/upgrade features, and no payment platform integrations. The keyword hits for 'license' refer to the BSD open-source license comment (background.js:2-3), and 'pro' hits are false positives from locale translation strings (e.g., 'problema' in Spanish) and code comments about 'process'. The extension is entirely free with all features available unconditionally.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension fetches the Gmail Atom feed at https://mail.google.com/mail/feed/atom (background.js:100) which requires the user to be logged into a Google account in the browser. When the fetch fails (user not logged in), it shows a 'gmail_not_logged_in.png' icon with a '?' badge (background.js:111-113). The extension itself implements no login UI — it relies entirely on existing Google session cookies in the browser. The core workflow (displaying unread count) cannot function without an active Google/Gmail login.
