Nirantar

Continuous Time

Nirantar is a calm, hand-tuned clock for Android — alarms, a timer, a stopwatch, and a live solar-system view of exactly where you are on Earth right now. Built for people who want the time of day to feel like a quiet ritual instead of a notification.

What's inside

Nine watch faces

Nirantar, Trishul, Bindu, Shudh, Mudra, Ekant, Rekha, Jyoti, Vidyut — pick one in Settings, swipe between them on the Clock screen. Smooth-sweep second hand throughout.

Custom alarm sounds

Four bundled ambient tracks — Bansuri, Sitar, Nadi, Shankh — designed for gentle waking. System ringtones still available.

Smart alarms

Per-alarm vibration, gradual wake, snooze duration, and an opt-in "delete after alarm goes off" toggle so one-shot alarms don't pile up.

Timer & stopwatch

Drag-to-set circular timer up to 60 minutes, with a five-second snap. Stopwatch with lap times and best-lap highlight.

Sky screen

A live, top-down solar-system view of Earth, the Sun, the Moon and you — annotated and updated every 30 seconds. Day/night terminator computed from your location.

Lock-screen alarms

Full-screen alarm UI that wakes the screen and shows over the lock screen, with snooze and dismiss controls within reach.

Permissions, and why

Permission	Purpose
`ACCESS_COARSE_LOCATION`	Approximate location → drives the day/night calc and the "you" dot on the Sky screen, plus the city + weather strip on the Clock screen. Never leaves your device except to fetch open weather data.
`SCHEDULE_EXACT_ALARM` / `USE_EXACT_ALARM`	Required so alarms fire at the exact minute you set, even when the phone is in Doze mode.
`USE_FULL_SCREEN_INTENT`	Lets the alarm UI take over the lock screen when an alarm goes off.
`POST_NOTIFICATIONS`	For the alarm-ringing notification and snooze controls.
`FOREGROUND_SERVICE` + `FOREGROUND_SERVICE_MEDIA_PLAYBACK`	Required to keep the alarm sound playing reliably until you snooze or dismiss.
`VIBRATE`	Per-alarm vibration pattern.
`WAKE_LOCK`	Briefly held while an alarm fires so the screen turns on.
`RECEIVE_BOOT_COMPLETED`	Re-arms enabled alarms after a phone reboot.
`INTERNET`	Fetches current weather and weather-code from Open-Meteo using only your coarse coordinates.

Privacy policy

Nirantar collects your approximate location on-device, with your permission, in order to:

compute whether the sun is currently above or below the horizon at your position (Sky screen),
display your city's name on the Clock screen,
fetch a current weather reading from the public Open-Meteo API.

Your location is stored only in the app's private SharedPreferences on your device. It is sent only to Open-Meteo, and only as latitude / longitude pairs, in the URL of an HTTPS request, in order to retrieve the weather reading. Open-Meteo does not require an API key and does not link the request to a personal account. The app does not include any analytics SDK, tracker, ad network, crash reporter, or third-party identifier. No data is shared with the developer or with any other third party.

You can revoke location permission at any time in Android's app settings; the app will keep working with the day/night view falling back to your device's local clock.

Children's privacy: Nirantar does not knowingly collect any personal data from children. The app does not show ads or in-app purchases.

Account data: Nirantar has no accounts, no sign-in, no cloud sync. Everything stays on your device.
