Privacy Policy

Last updated: 4 November 2026

ShubhDin (“the app”) is a Hindu calendar and festival companion for Android, made by Saral Labs, published as com.dip.shubhdin. This policy explains what stays on your phone, what may go to Google, and how to export or delete your data.

ShubhDin is not an official government or temple almanac. Festival dates and panchang details are computed on the phone; your local Panchang may differ on rare dates.

The short version

Your family names, birthdays, anniversaries, punyatithi dates, greeting cards, and city choice stay in the app’s private storage. We operate no ShubhDin server and you have no account. Nothing you type about your family is sold or uploaded to us.

The app may use the internet for Google AdMob (non-personalised ads), Firebase Remote Config (signed festival corrections), optional Google Analytics (only if you turn it on), Firebase Crashlytics (always on when Firebase is configured), and Google Play updates and review. We do not sell your information.

What we store on your phone

Home location — city name, latitude, longitude and time zone you pick from the built-in list. ShubhDin does not request GPS.
Calendar choices — region pack, tradition, month system, languages, theme, and display options.
Family people and events — names, relations, optional photo references, birthdays, anniversaries, punyatithi and custom occasions, reminder settings, and private flags.
Occurrence cache, wish log, card drafts, reminder preferences, and analytics consent.

Other apps cannot read this data. Android cloud backup is off for the app. Uninstalling removes it unless you exported a copy yourself.

What we never send

Family names, photos, dates you enter, greeting message text, or your family export file — unless you choose to share an export through Android’s share sheet.

Export and deletion

Export family pack (Settings → Privacy & data) saves JSON you control. Photos are omitted by default.
Delete all data removes people, events, drafts and caches on the phone.
Cards can export a festival calendar file or a year-list image when you ask.

Advertising (Google AdMob)

A banner may appear at the bottom of the Calendar tab only.
A full-screen ad may appear after you successfully share from the app, at most once per session — never on cold start.
Every request is non-personalised (npa=1), including after Google’s User Messaging Platform consent flow.
AdMob may receive your device advertising ID, approximate location from IP, device information and ad interactions, as described in Google’s advertising policy.

Your family data and panchang details are not sent to advertisers.

Usage analytics (opt in)

Google Analytics for Firebase runs only if you enable Share anonymous analytics. When off, no analytics events are sent. When on, we receive coarse feature use and screen views — never names, dates or message text. The advertising ID is not collected for analytics. See Firebase privacy.

Crash diagnostics

Firebase Crashlytics reports crashes and ANRs when Firebase is configured. This helps fix failures. Reports may include stack traces, app and device metadata, and an installation identifier — never family names, dates or card text. See Crashlytics privacy.

Festival overrides (Remote Config)

Signed JSON may download from Firebase Remote Config to correct festival dates between app updates. It is verified before apply. Your family list is not included in fetches.
