Privacy Policy
Effective 29 September 2026
Your spiritual journey is personal. Tattvamasi is built on that principle, and this policy explains exactly what we collect, why we collect it, and what you can do about it.
This policy is issued by CognidaX LLP ("we", "us"), which is the Data Fiduciary for the personal data processed through the Tattvamasi mobile application and website.
1. What we collect and why
If you create an account
- Name and contact details (mobile number or email address), used to create and secure your account and to sign you in
- The city you select, used to calculate panchang timings and location-appropriate guidance
- Your precise GPS location, requested when you use the temple finder feature to discover nearby temples, or when you tap 'Use my location' during account setup to detect your city. When you use the temple finder, your coordinates are sent to Google to find nearby temples, and the last-used coordinates are saved on your device only so the screen reopens where you left it. When you tap 'Use my location' during setup, your coordinates are sent to Google to identify your city; they are not stored with your account. Your location is not shared with advertisers and is not used for any other purpose.
- Birth date, birth time and birth place, collected during account setup; this step can be skipped. If provided, they are used to compute your Jyotish chart
- Spiritual preferences such as deity, tradition, intentions and age group, used to personalise the content you see
- Journey progress, favourites and session history, used to keep your place and show you where you have been
- Device notification token, used to send the reminders you have turned on
- Profile photo and memorial photos, if you choose to add them. These are taken using your camera or chosen from your photo library, and stored securely in your account
- Personal records you choose to create, such as bereavement records, life events and daily reflections, stored privately in your account
If you use the app as a guest
You can use Tattvamasi without an account. In guest mode we do not collect your name, contact details or birth details. Your preferences and progress are stored on your device and are lost if you uninstall the app.
Collected either way
- Anonymous crash reports and usage events, used to find and fix problems and to understand which features are used
- Basic technical data such as device model, operating system version and app version, used for compatibility and support
2. What we never do
- Sell or rent your data to anyone
- Share your personal information with advertisers
- Access your contacts or microphone
- Track you across other apps or websites
- Use your birth details or spiritual preferences for advertising
3. Consent
We process your personal data on the basis of the consent you give when you create your account and when you switch on individual features. Consent is requested separately for optional features, such as Jyotish, that require additional personal data.
You can withdraw consent at any time. Turn off notifications under Me → Notifications, remove your birth details under Me → Profile, or delete your account under Me → Delete my data. Withdrawing consent does not affect processing carried out before withdrawal, and some features will stop working once the data they depend on is removed.
4. Service providers
We use the following providers to run the app. Each receives only the data it needs for its function.
- Authentication & infrastructure (Google Firebase): account creation, sign-in, database storage, crash reporting and push notifications
- Astrology calculations (Prokerala): the coordinates of the city you select are sent to compute panchang timings. For Jyotish features, your birth date, time and birth-place coordinates are sent to compute your chart. If you use Numerology, the name you enter is sent; if you use Kundli matching, the birth details you enter for both people are sent. This data is used only to return the calculation.
- Location services (Google Maps Platform): the text you type in the city or birth-place search box is sent to find matching places (Places Autocomplete), and the place you pick is looked up to get its coordinates and time zone. When you use the temple finder, your GPS coordinates are sent to find nearby temples (Places Nearby Search). When you tap 'Use my location' during setup, your GPS coordinates are sent to the Google Geocoding API through our servers to identify your city.
- Photo storage (Firebase Storage): profile photos and memorial photos you upload are stored in Firebase Storage under your account. No other data is stored there.
- SMS sign-in (Twilio): your mobile number is used for one-time verification only and is not stored by the provider beyond that.
- Email sign-in (Google): when you sign in by email, a one-time code is sent from support@tattvamasi.app using Gmail. Google receives your email address to deliver the message.
- AI assistant (Anthropic Claude API): powers the in-app Ask & Learn feature. Only the text of your question is sent to generate an answer. Please do not include personal or sensitive information in your questions. This content is not used to train AI models.
5. Transfers outside India
Some of the providers listed above process data on servers located outside India. Where this happens, we transfer your personal data only as permitted under Section 16 of the Digital Personal Data Protection Act, 2023, and we require our providers to apply appropriate security safeguards.
6. Security
We protect your data using encryption in transit, encryption at rest for stored personal data, access controls that limit staff access to what is necessary, and logging of access to production systems. No system is completely secure, so we also keep the amount of data we hold to the minimum the app needs.
If a personal data breach affects your data, we will inform you and the Data Protection Board of India in the manner and within the timelines required by law, describing what happened, what it may mean for you, and what we are doing about it.
7. Retention and deletion
We keep your personal data for as long as your account is active.
When you delete your account from Me → Delete my data, we begin deletion immediately. Your personal data is removed from our live systems within 30 days and from encrypted backups within a further 90 days. After that we retain only what we are required by law to keep, and anonymous, non-identifying analytics that cannot be linked back to you.
If your account remains inactive for 24 months, we will contact you and then delete the account and its personal data unless you sign in.
You can also request deletion by writing to support@tattvamasi.app.
8. Your rights
Under the Digital Personal Data Protection Act, 2023, you have the right to:
- Access a summary of the personal data we hold about you and how it is processed
- Correct, complete or update inaccurate personal data
- Erase your personal data where it is no longer needed for the purpose it was collected
- Nominate another person to exercise these rights on your behalf in the event of your death or incapacity
- Raise a grievance with us, and escalate to the Data Protection Board of India if you are not satisfied with our response
Most of these can be exercised directly in the app under the Me tab. For anything else, write to support@tattvamasi.app. We will respond within 30 days.
9. Age
Tattvamasi is for users aged 18 and above, including in guest mode. We do not knowingly provide services to, create accounts for, or collect personal data from, anyone under 18.
If we learn that we hold personal data belonging to a person under 18 without verifiable parental or guardian consent, we will delete it. If you believe this has happened, write to support@tattvamasi.app.
10. Changes to this policy
We will update this policy when the app changes. If a change materially affects how we handle your personal data, we will notify you in the app or by email before it takes effect, and where the law requires it, we will ask for your consent again. The effective date at the top of this policy always reflects the current version.
