Privacy Policy
SIAstro is a chat-based Vedic and K.P. astrology app for spiritual guidance and self-reflection. This policy explains what we collect, why, where it is stored, who else sees it, how long we keep it, and the choices you have.
SIAstro is operated by Datacells AI LLC ("we", "us"). Contact: privacy@siastro.ai for privacy requests, support@siastro.ai for anything else.
1. What we collect
| Data | Examples | Why |
|---|---|---|
| Account | User ID; name and email from your sign-in provider or the email you sign up with (some providers give a private relay email instead of your real one); how you signed in. Guests have only a random ID. | To sign you in and keep your data yours. |
| Country and home region | The country you choose at sign-up. | To decide where your data is stored (section 3). |
| People and birth details | Names, relation (self, family, other), date, time and place of birth, and the place's coordinates and time zone. | To compute charts, dashas and panchang, and answer questions about them. |
| Questions and answers | The chat questions you ask and the answers we give, including any personal topics you choose to mention. | To answer you and show your past readings. |
| Approximate location (optional) | With your permission, the nearest city to your phone. Never your exact position, and not stored. | To show today's panchang where you are. |
| Settings and consent | Name style, chart style, and when you agreed to this policy and the Terms. | To run the app as you set it, and to keep a record of your consent. |
| App and device checks | A token from your phone's operating system proving requests come from the genuine app. | To protect the service from abuse. |
We don't need, and don't ask for, government ID. Birth details are whatever you enter. We don't use advertising IDs, advertising, or third-party analytics or tracking.
You may choose to mention sensitive matters in a question, such as health, family or religious and spiritual beliefs. We use them only to answer that question and to keep it in your history.
2. How we use it
- To provide the app: compute charts, answer your questions, keep your folders and past readings.
- To keep it safe and working: sign-in, abuse prevention, usage limits, fixing errors. Our server logs contain request IDs and event names, never your birth details or chat text.
- To meet legal obligations, such as responding to valid legal requests.
We don't sell or rent your data. We don't use it for advertising or for profiling unrelated to answering you. Our AI provider may not use your data to train its models.
Legal basis (UK/EU users): performance of our contract with you; your explicit consent, given in the app, for sensitive matters you choose to share and for transfer to our AI provider; and our legitimate interest in keeping the service secure.
3. Where your data is stored
Your folders, birth details and chat history are stored with our cloud database provider in the region that matches the country you chose:
| Region | Location | Who it covers |
|---|---|---|
| India | Mumbai | India, rest of South Asia, Middle East |
| United States | Iowa | US, Canada, Latin America, other countries not listed, and all guests |
| United Kingdom | London | UK, EU, rest of Europe, Africa |
| Indonesia | Jakarta | Southeast and East Asia |
| Australia | Sydney | Australia, New Zealand, the Pacific |
Sign-in records are kept by our sign-in service, which is global. Guest data is stored in the default region shown above until you create an account, when it moves to your region.
Processing outside your home country. To answer a question, our server sends the question, the birth details it needs and recent conversation context to our AI provider. Birth details also go to our chart-calculation service, which stores nothing. Our server, chart-calculation service, AI provider and other service providers may be located outside your home country. Where the law requires it (for example for UK and EU users), these transfers are covered by standard contractual clauses or equivalent safeguards in our providers' data processing terms.
4. Who else receives data
We use service providers to run SIAstro. They process data only on our instructions, under contracts that require them to protect it, and may not use it for their own purposes.
| Type of provider | What for | Data |
|---|---|---|
| Cloud hosting and database | Running our server, storing your data, encryption keys | The data in section 1 |
| AI provider | Writing answers | Questions, the birth details they need and recent conversation context, for each answer |
| Chart calculation | Computing charts, dashas and panchang | Birth details and coordinates, while handling a request; nothing is stored |
| Sign-in and app integrity | Signing you in; checking requests come from the genuine app | Sign-in and app check tokens, and the name and email your sign-in provider shares |
| Monitoring | Keeping the service reliable, affordable and safe | Usage and technical information, such as timing, errors and cost of requests |
You can ask us for the current list of providers at privacy@siastro.ai. We may also disclose data where the law requires it, or to protect someone's safety.
5. How long we keep it
- While your account is open: your folders, birth details and chat history, until you delete them or your account.
- Deleting a chat: email us; we delete it within 48 hours.
- Deleting your account (Settings → Delete account): your account is disabled at once, and your data is deleted within 24 hours. We then keep an encrypted archive of it in your region for 180 days, only so we can meet legal obligations (for example, a valid legal request). Only authorised Datacells AI LLC staff can decrypt it, and every decryption is logged. After 180 days the archive is deleted automatically, unless the law requires us to keep it longer.
- Guest data can't be recovered once you sign out of guest mode. We may delete guest data that hasn't been used for a long time.
- Server logs (no birth details or chat text) are kept for up to 90 days.
6. Your choices and rights
- Access and correct: view and edit your folders and birth details in the app.
- Delete: delete your account in the app (Settings → Delete account), or email us to delete particular chats.
- Copy: email us for a copy of your data in a common format.
- Withdraw consent: you can delete your account at any time. Withdrawing consent doesn't affect processing already done.
- Location: location is optional; you can turn it off at any time in your phone's settings, and the rest of the app works without it.
- Complain: contact us first. You may also complain to your data protection authority, for example the Data Protection Board of India, the UK Information Commissioner's Office, your EU supervisory authority, or the Office of the Australian Information Commissioner.
These rights apply under laws including India's Digital Personal Data Protection Act 2023, the UK and EU GDPR, Indonesia's Personal Data Protection Law, Australia's Privacy Act 1988 and US state privacy laws. We answer requests within 30 days, usually much sooner. We may need to confirm it's you, for example by asking you to email from your account's address.
California residents
We don't sell or share personal information for cross-context behavioural advertising, and we don't track you across other websites or apps. Because of that, we treat all users the same whether or not their browser sends a "Do Not Track" signal. You may ask us what personal information we hold about you and ask us to correct or delete it, as described above.
7. Other people's details
You can add birth details for family members and others. Please add someone else's details only if they would be comfortable with it. They can ask us to remove their details by emailing us.
8. Age
SIAstro is for adults 18 and over. We don't knowingly collect data from anyone under 18. If you believe a child has used the app, email us and we will delete the account.
9. Security
All data is encrypted in transit (HTTPS) and at rest (AES-256, managed by our cloud providers). Database rules allow each user to read only their own data, in their own region. Access by our server is limited to what it needs. Deletion archives are encrypted with keys held in a key management service in your region. No system is perfectly secure. If a breach affects your data, we will notify you and the relevant authorities as the law requires.
10. Changes
If we change this policy in a way that matters, we will tell you in the app and ask for your agreement again where the law requires. The version and date are at the top.
