Chimely

Privacy Policy

Last updated: 2 July 2026

Chimely is a mosque-style LED clock that chimes every quarter-hour and can sound the azan at the five daily prayer times. Chimely does not run user accounts and does not ask you for personal details. The only data leaving your device comes from the advertising component described below.

Summary

Chimely has no user accounts and collects no personal details such as your name, email, or phone number.
Your settings and your chosen location are stored only on your device and are removed when you uninstall the app.
Chimely shows banner ads through Google AdMob. Google's advertising SDK collects device and advertising identifiers to serve and measure ads — this is the one place data leaves your device.
Prayer times are calculated entirely on your device. Your coordinates are never transmitted anywhere.

Advertising

Chimely displays banner advertisements using Google AdMob (the Google Mobile Ads SDK). To serve and measure ads, Google and its ad partners may collect and process:

Device and advertising identifiers (including the Android Advertising ID).
Approximate, IP-derived location and general device information.
Ad interaction and performance data (for example, whether an ad was shown or tapped).

This data is collected and used by Google in accordance with its own policies. You can learn how Google uses information from apps that use its services here: How Google uses information from sites or apps that use its services, and read the Google Privacy Policy.

Where required by law (for example, in the European Economic Area and the UK), Chimely presents Google's consent (UMP) form before requesting ads, so you can choose whether personalised ads are shown. You can reset or change this choice at any time from your device and Google ad settings. You can also limit ad personalisation system-wide via Android Settings → Privacy → Ads.

Location

If you enable prayer times, the app can use your location to calculate them. Location is used in the most private way possible:

It is read only when you tap "Detect my location" — never in the background and never continuously.
Chimely requests only approximate (coarse) location, and only once.
Prayer times are calculated entirely on your device. Your coordinates are stored only on your phone and are never transmitted by Chimely (there is no reverse geocoding or online lookup).
You can skip location access entirely by entering your location manually.

Data stored on your device

Your preferences — chime style, volume, LED colour, schedule window, theme, widget transparency, prayer-time settings, and your chosen location — are stored only on your device using Android's local app storage. They never leave your phone and are removed when you uninstall the app.

City name data

City names shown for your prayer-times location come from a bundled offline dataset derived from GeoNames, licensed CC BY 4.0. The lookup runs entirely on your device; no coordinates or location data are ever sent anywhere.

Permissions and why they are used

Alarms & reminders (exact alarm) — to sound the chime/azan precisely on time. If not granted, they still play but may drift by a few minutes.
Run at startup (boot completed) — to resume chiming after the device restarts.
Wake lock — to keep the device awake just long enough to finish playing a chime or azan.
Approximate location (coarse) — only to compute prayer times on-device, as described above. Optional; manual entry avoids it.
Network access — used by the Google AdMob advertising component to load ads.

Data sharing and security

Chimely itself does not sell or share your personal information. The only third party that receives data is Google, through the AdMob advertising SDK, as described in the Advertising section. Data transmitted by that SDK is sent over encrypted (HTTPS/TLS) connections.

Data deletion

Because Chimely stores your settings only on your device and keeps no account or server-side copy, uninstalling the app permanently deletes all data it stored. For advertising data held by Google, you can reset your Advertising ID or opt out of ad personalisation in your Android settings. Questions or deletion requests can be sent to the contact address below.

Children's privacy

Chimely is intended for a general adult audience and is not directed to children. We do not knowingly collect personal information from children.

Changes to this policy

If this policy ever changes, the updated version will be published at this same location with a new "Last updated" date.
