This Privacy Policy applies exclusively to the Kaal Sutra application. All data described below stays on your device unless explicitly noted otherwise.
Chrono Solutions ("we") publishes the Kaal Sutra app for Android and iOS. This policy explains what the app handles and what it does not. Kaal Sutra calculates panchanga, kundli, matchmaking, and family calendars on your device. We do not run an account server for this app.
The app saves these items in local storage on the phone. They are not uploaded to Chrono Solutions:
The app needs a place to calculate the panchanga. You can pick a city from the built-in list. If you search for another place, or if you tap to use GPS, the app sends that search text or those coordinates to OpenStreetMap Nominatim so it can return a place name. That request is used to fill the city field. We do not keep a location history.
GPS runs only when you ask for it. You can refuse the Android location permission and still use a city you select yourself.
On the Google Play version, Free and Astro tiers show ads through Google AdMob. Those ads can include a banner and a rewarded video. The rewarded video unlocks Kundli, Family, and Festivals for two hours. Ad-Free, Astro Pro, and Astro Plus do not show these ads.
Google may receive an advertising identifier, device information, and an IP address to deliver and measure ads. Where the law requires a choice, the app asks before personalized ads are requested. You can reset or delete the Android advertising ID in your phone settings.
Digital plans and report passes are sold through Google Play Billing. Google processes the payment. Chrono Solutions does not receive your card number. Google shares a purchase receipt with the app so the plan can be turned on for this device. Play's own privacy policy covers the payment.
When you tap share, the phone's share sheet sends the image or text you chose to the app you pick, such as WhatsApp. That send happens only after you confirm it.
Kaal Sutra is not directed at children under 13. A family calendar can hold birth details of people in your household, including children, because you typed them. Those details stay on your device. Add another person's details only if you are allowed to.
On-device information remains until you change it, clear the app storage, or uninstall. Purchase records are kept by Google under Play's rules. Ad measurement records are kept by Google under AdMob's rules.
We may update this Privacy Policy as Kaal Sutra evolves. Changes will be indicated by an updated effective date at the top of this document. Continued use of the app after a policy update constitutes your acceptance of the revised terms.
We will update this page if the app's data practices change. The date at the top is the current version.
