Live prayer-time countdown with automatic cross-tab media pausing.
Adhan Caster Pro is built to be privacy-friendly. It does not use analytics or trackers, does not require an account, and does not sell or share your data. Your settings stay on your own device. The only information sent off your device is the location you choose (a city name) and the text you type into the location search — used solely to look up prayer times and resolve places.
This policy covers the Adhan Caster Pro Chrome extension ("the extension"). It is a standalone browser extension published on the Chrome Web Store.
The extension works with a small amount of data, all of it tied to its core features:
| Data | Why it's used | Where it lives |
|---|---|---|
| Your chosen location (city, region/state, country, and the coordinates of the place you pick) | To fetch the correct daily prayer times and display them. | Stored locally on your device; the city/region/country are sent to the prayer-times API (see below). |
| Location search text you type | To find and resolve real places while you set your location. | Sent to the Open-Meteo geocoding API as you type (see below); not otherwise stored. |
| Your preferences (enable toggle, heads-up lead time, auto-resume delay, focus-mode toggle) | To make the extension behave the way you configured it. | Stored locally on your device only. |
| The fetched prayer schedule and current pause state | To show the countdown and pause/resume media at prayer time. | Stored locally on your device only. |
Local data is held in your browser's extension storage (chrome.storage.local) and never
leaves your device except as described in "Third-party services" below.
To do its job, the extension makes requests to two external services:
adhan-api-mauve.vercel.app) — receives the
city, region/state, and country you selected in order to return that location's prayer
times. No personal identifiers are sent.
geocoding-api.open-meteo.com, see the
Open-Meteo terms & privacy)
— receives the text you type in the location search to return matching places and their
coordinates.
As with any web request, these services automatically receive standard technical metadata (such as your IP address and request time). The extension itself does not attach any identifier to these requests. Data handling by these third parties is governed by their own policies.
The extension's content script interacts with a page only to find <video> and
<audio> elements so it can pause and resume them at prayer time. It does not inspect
or send page content anywhere.
| Permission | Purpose |
|---|---|
storage | Save your settings and the prayer schedule locally. |
alarms | Trigger the countdown and pause exactly at prayer time. |
notifications | Show the desktop notification when it's time to pray. |
scripting | Insert the pause/countdown logic into pages that are already open when you install or update. |
tabs | Send the pause/resume signal to your open tabs. |
Access to websites (http://*/*, https://*/*) | Required so media can be paused in any tab at prayer time — the extension's core feature. |
All settings and schedule data live on your device. You can clear your saved location and preferences
at any time from the extension's settings, or remove everything by uninstalling the extension from
chrome://extensions. The developer holds no server-side copy of your data.
The extension is not directed at children and does not knowingly collect any information from children.
If this policy changes, the updated version will be posted at this URL with a new "Last updated" date.
