Private by design

Your birth details are nobody else's business

Many astrology apps send your birth date, time and place to a server. Rudra doesn't have one.

  • Calculated on your phoneCharts, horoscopes, panchang, matching and Ask Rudra's answers are all computed on the device.
  • No internet permissionThe app doesn't request Android's Internet permission, so it can't send anything over the network.
  • No account, ads, analytics or crash reportingThere is nothing to sign up for and no tracking of any kind.
  • Your backup, your choiceIf you turn on Android backup, Android can include Rudra's saved kundlis in your own Google account backup. You can switch that off in Android settings.

Questions and answers

Is Rudra free?

Yes. There are no ads, no in-app purchases and no subscription.

Does Rudra need the internet?

No. Rudra doesn't even request the Internet permission. Everything, including Ask Rudra, is calculated on your phone, so it works in flight mode.

Is Ask Rudra an AI chatbot?

Ask Rudra is a rule-based astrology engine, not a generative AI model. It reads your chart with classical Jyotish rules (houses, lords, dashas, transits, yogas and doshas) and builds its answer from Rudra's own written interpretations. Your question never leaves your phone.

Where is my data, and how do I delete it?

Your kundlis, chats and settings are stored only in the app's private storage on your phone. If Android backup is on, Android may include them in your own Google account backup.

To delete them: remove a kundli in the app, use "Clear chat" in Ask Rudra, or uninstall the app (or go to Android Settings → Apps → Rudra → Storage → Clear storage).

Why did a reminder arrive late, or not at all?

To save battery, Android delays alarms while the phone is in deep sleep. A Rahu Kaal heads-up can arrive a little late, and it's skipped if Rahu Kaal has already ended.

If the app is force-stopped, or a phone's battery optimizer stops it, its reminders are cleared until you open Rudra again. On phones with aggressive battery savers, allow Rudra to run in the background (Settings → Apps → Rudra → Battery).

Which phones does Rudra work on?

Android 8.0 and later. The app is designed for phones and also works on tablets.

Which ayanamsa and chart styles are available?

Lahiri (Chitrapaksha), KP and Raman ayanamsa; mean or true Rahu; North or South Indian charts. Change them in Settings.
