This Privacy Policy explains what information the Sidishtro mobile app ("the app", "we", "us") collects, how it is used, who it is shared with, and how you can delete it. By using the app you agree to this policy.

1. Information we collect

Account information

Your Google account identity (name, email address and profile identifier) if you sign in with Google.
Your phone number, if you sign in with a one-time code sent by SMS.
A unique account identifier issued by Firebase Authentication.

Profile and birth details

Name, date of birth, time of birth and place of birth (including the latitude, longitude and time zone derived from the place) for you, and for any other person ("guest") whose chart you choose to create.

Generated content

The astrological charts, Dasha periods, interpretations, predictions, horoscopes and Kundli matches calculated from the birth details above.
AI-generated explanations you request, and cached daily and weekly horoscope results.

Preferences

Your language choice and your selected active profile.

We do not collect your precise device location, contacts, photos, microphone or advertising identifiers. The app contains no advertising and no third-party analytics or tracking SDKs.

2. How we use your information

To sign you in and keep your account secure.
To calculate your charts, Dasha periods, interpretations, predictions, horoscopes and Kundli matches.
To generate natural-language explanations when you tap "Explain with AI".
To remember your preferences and make the app faster by caching results on your device.

We do not sell your personal information, and we do not use it for advertising or profiling.

3. Where your data is stored

Your profile, birth details and generated charts are stored locally on your device in the app's database. They are not uploaded to a server for storage by us.

4. Information sent to services and why

To provide the app's features, some data leaves your device:

Recipient	What is sent	Why
Firebase Authentication (Google)	Phone number or Google account identity	To sign you in and verify your identity. For phone sign-in, Google sends the one-time code by SMS.
Astrology calculation service (our backend, hosted on Google Cloud Run)	Birth date, time and place (and the date for transit/horoscope calculations)	To calculate planetary positions and charts. The service returns results to your device; it does not keep your data for its own use.
OpenAI, via our AI gateway	The already-calculated chart, prediction or match details needed for the explanation, and your language	Only when you tap "Explain with AI", to produce a plain-language explanation. We do not send your phone number or email. OpenAI processes the request under its own privacy policy and API data terms.

All data sent over the network is encrypted in transit (HTTPS/TLS).

AI explanations are generated by a language model and may contain mistakes. They only explain results the app has already computed.

5. Sharing

We share information only with the service providers listed in Section 4, and only as needed to operate the features above. We may also disclose information if required by law. We do not sell or rent your data.

6. Data retention

Data on your device is kept until you delete it or uninstall the app.
Your Firebase account is kept until you delete your account.
Data sent to our calculation service and to OpenAI is used to produce a response. Providers may retain request data for a limited period for security, abuse prevention and legal compliance, according to their own policies.

7. How to delete your data

Delete a profile or guest: open Settings → Manage Profiles and choose Delete. This removes that profile's birth details, charts and saved AI explanations from your device.
Delete all data from your device: uninstall the app, or clear its storage in Android Settings.
Delete your account: open Settings → Manage Profiles → Delete Account and confirm. This immediately and permanently deletes your sign-in account (Google or phone identity) and every profile, guest and chart stored on your device. If you can no longer access the app, you can request deletion at https://sidthstro-prj.web.app/delete-account or by emailing indiaairtel0605@gmail.com from the email address or phone number you signed in with; we will delete your sign-in account within 30 days of a verified request.

8. Your rights

Depending on where you live, you may have the right to access, correct, delete or export your personal data, and to withdraw consent. Most of your data is on your device and can be viewed, edited or deleted in the app. For anything else, contact us at indiaairtel0605@gmail.com.

9. Children

The app is intended for users aged 18 and over. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.

10. Security

We use encryption in transit, Firebase Authentication for sign-in, and keep API keys for AI services on the server rather than in the app. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.

11. Disclaimer

Astrological content is provided for entertainment and general guidance only. It is not professional medical, legal, financial or psychological advice, and it does not guarantee any outcome.

12. International transfers

Our service providers (Google/Firebase, Google Cloud, OpenAI) may process data in countries other than your own, including the United States. By using the app you understand your data may be transferred and processed there.

13. Changes to this policy

We may update this policy from time to time. The "Last updated" date above shows the latest revision. Material changes will be communicated in the app or on this page.
