Privacy Policy for Tithi
Last updated: [Effective Date]
Tithi (“Tithi,” “we,” “us,” or “our”) is a Hindu calendar mobile application operated by Shiachi.co, an individual based in Gurugram, India. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using Tithi, you agree to this Policy.
1. Information we collect
Account information. When you sign in with Google or Apple, we receive basic profile information such as your name, email address, and a unique account identifier, used to create and secure your account. We store authentication tokens in encrypted storage on your device.
Your content. Calendars, events, reminders, and related details you create are stored on your device and synced to our servers so they are available across your sessions. We do not use your event content for advertising.
Location (optional). If you grant permission, we use your device’s approximate or precise location to calculate accurate tithi, sunrise, and sunset times for where you are. Location is used for these calculations and is not used to track you over time. If you decline, Tithi uses a default reference location (Ujjain) and the app remains fully usable.
Diagnostics and usage data. We use Google Firebase (Analytics, Crashlytics, and Performance Monitoring) to understand how the app is used, diagnose crashes, and improve performance. This may include device model, operating-system version, app version, crash logs, and in-app events. This data is used in aggregate.
Advertising. Tithi displays ads through Google AdMob. Depending on your consent and region, advertising partners may process advertising identifiers to show and measure ads. On first launch we present a consent request (Google’s User Messaging Platform) where applicable, and we honor your choice.
Notifications. If you enable notifications, we use Firebase Cloud Messaging to deliver daily summaries and reminders. You can turn notifications off at any time in the app or your device settings.
2. How we use your information
- To provide and sync the calendar, events, and reminders.
- To calculate location-based tithi, sunrise, and sunset (with your permission).
- To send notifications you have enabled.
- To maintain security, prevent abuse, and operate your account.
- To analyze usage, fix crashes, and improve the app.
- To display and measure advertising, consistent with your consent.
3. How we share information
We do not sell your personal information. We share information only with:
- Service providers who operate the app on our behalf — Google (Sign-In, Firebase, AdMob) and Apple (Sign in with Apple) — who process data under their own terms and privacy policies.
- Legal and safety purposes, when required by law or to protect rights and safety.
Relevant third-party policies: Google Privacy Policy (policies.google.com/privacy) and Apple Privacy Policy (apple.com/legal/privacy).
4. Data retention
We keep your account and content for as long as your account is active. When you delete your account or request deletion, we delete or anonymize your personal data within a reasonable period, except where retention is required by law.
5. Your rights and choices
- Access, correction, deletion: Request a copy, correction, or deletion of your data by emailing support@shiachi.co.
- Delete your account: Use the in-app account option or contact us.
- Permissions: Control location and notification permissions in your device settings at any time.
- Ad personalization: Adjust ad-consent and device advertising settings where available.
6. Security
We use reasonable technical and organizational measures, including encrypted on-device token storage and secure transport, to protect your information. No method of transmission or storage is completely secure.
7. Children’s privacy
Tithi is not directed to children under 13 (or the minimum age in your jurisdiction). We do not knowingly collect personal data from children. If you believe a child has provided us data, contact support@shiachi.co and we will delete it.
8. International users
We are based in India and may process data in India and in countries where our service providers operate. By using Tithi you consent to such processing.
9. Changes to this Policy
We may update this Policy from time to time. We will revise the “Last updated” date and, for material changes, provide additional notice.
