Privacy Policy — Panchangam (iOS)

Effective date: May 12, 2026 · App: Panchangam — Hindu Almanac for iOS (bundle dev.tnc.panchangam) by TnC Apps.

We respect your privacy. This policy explains, in plain language, what data the Panchangam iOS app handles and what it does not do. A separate policy applies to the Panchangam Android app and to the Panchangam web app.

Summary

We do not collect personal data.
No accounts, no logins, no sign-up.
No advertising SDKs, no third-party analytics SDKs, no tracking, no IDFA.
All panchangam, kundali, porutham, baby-name and vrat-guide calculations run on your device.

What information the app processes

Panchangam computes traditional Hindu calendar values (tithi, nakshatra, sunrise, muhurtam, kundali, porutham, vrat guides, etc.) for a date and place that you choose. To do this, the app processes:

The city you select (or the latitude / longitude / timezone of a custom city you enter). Used only to perform the astronomical calculation and to display the result back to you.
The date you select.
Optional birth details for Kundali / Porutham / Baby Name (date, time, place). Used only to generate the chart shown on screen. Never uploaded.
Optional family-member profiles you choose to save for quick access. Stored only on your device.
Your preferred language (English, Telugu, Kannada, Tamil, or Hindi).
Notification preferences (daily panchangam reminder time, festival reminder toggle). Stored only on your device.

Where this information is stored

Your selected city, language, saved profiles, and notification preferences are stored only on your device using UserDefaults and the app’s sandboxed storage. Nothing is uploaded to our servers.
The home-screen widget reads the same on-device preferences through an App Group container; the widget does not perform any network requests.
We do not maintain user profiles, accounts, or histories on any server.

Network requests

The iOS app does not require an internet connection for core panchangam, kundali, porutham, baby-name, festival and vrat features — everything is computed on-device.

If you use the optional “custom city” search, the app queries Apple’s MapKit local-search service to resolve a place name to coordinates. Those queries go directly to Apple and are governed by Apple’s Privacy Policy.
External links you tap (such as “Contact support”) open in your browser or Mail app and are subject to that destination’s own policy.

Permissions used by the iOS app

Location (When In Use) — optional. Used only when you tap “Use my location” in the city picker to determine your current city for the panchangam calculation. The coordinates are used on-device and are never transmitted to our servers. You can decline this permission and pick a city manually instead; all features still work.
Notifications — optional. Used only to deliver the daily panchangam summary and festival reminders that you opt in to from the Settings screen.
The app does not request access to your contacts, microphone, camera, photos, calendar, health data, motion data, Bluetooth, or any other sensitive device data.

Children’s privacy

Panchangam is a general-audience reference app rated 4+ and is not directed at children under 13. We do not knowingly collect any data from children.

Data retention & deletion

Because we do not store personal data on our servers, there is nothing for us to delete. To remove the local preferences and profiles saved by the app, either reset them from within the app’s Settings screen or uninstall the app — iOS will discard the app’s sandboxed storage automatically.

Changes to this policy

If we change how the app handles data, we will update this page and the “Effective date” above. Material changes will also be noted in the app’s release notes on the App Store.
