This Privacy Policy explains how the PSOTS Chhath Puja Committee handles your personal information when you use chhath.psots.in. This Site is built exclusively for the residents of Prestige Song of the South (PSOTS), Bengaluru — it is non-commercial, community-run, and carries no advertising of any kind.

We respect the trust you place in us when you share your details. Everything collected here serves one purpose: organising a beautiful Chhath Puja celebration for our community.

1. Information You Provide

1.1 Registration & Profile

• Name — to identify your contribution and, with your consent, display it on the contributors list.
• Flat Number — to confirm you are a PSOTS resident.
• Mobile Number — to send a WhatsApp receipt and for payment verification.
• Email Address — for sign-in (Google or OTP) and committee communication.

1.2 Contribution Details

• Amount contributed — recorded for community financial transparency.
• UPI app used — e.g. GPay, PhonePe — noted for reconciliation only.
• Transaction reference — optional, if you choose to share it.

1.3 Volunteer Sign-up

If you register as a volunteer, we additionally collect your availability and preferred tasks — used solely for assigning duties on the day of the event.

1.4 Prasad Registration

If you register for Prasad (Kharna/Thekua), we collect the names and headcount of family members collecting, and generate a QR pass tied to your flat — used solely to track and coordinate distribution on event days.

1.5 Support Tickets & Messages

If you raise a complaint or query — via the portal, WhatsApp, or email — we collect your name, phone/email, and the issue description, used solely to resolve it and keep you updated on its status.

2. How Your Data Is Stored

2.1 On Your Device (Browser Cache)

When you sign in, your profile details (name, flat number, photo) are saved locally in your browser so pages load instantly between visits. This local copy is a cache only — the authoritative record lives in our database. It is cleared when you sign out.

No tracking cookies, advertising cookies, or analytics cookies are used — ever.

2.2 In Our Secure Database

Details you submit — contributions, volunteer registrations, Prasad registrations, support tickets, WhatsApp opt-ins — are stored in a Cloudflare D1 database accessible only to authorised committee members. Payment receipt images and event gallery photos are stored in Cloudflare R2, under the same access controls. Cloudflare's infrastructure is ISO 27001 certified and SOC 2 compliant. Data is encrypted at rest and in transit.

3. How We Use Your Information

• To record and verify your contribution to the Chhath Puja 2026 fund.
• To display your name on the contributors list — only with your consent.
• To send a WhatsApp payment receipt, Prasad pass, and ticket updates (via Fonnte) — sent based on your contribution/registration, not a separate opt-in.
• To send general WhatsApp broadcasts (announcements, event reminders) if you've subscribed via the Subscribe page.
• To send a email receipt and contribution confirmation (via ZeptoMail from noreply@chhath.psots.in) when your payment is verified.
• To coordinate volunteer duties during the event.
• To maintain transparent financial records for the community.
• To keep you signed in across visits using your browser cache.

4. No Advertising. No Data Sharing.

The only parties who can access your submitted information are:

• Authorised committee members — for managing contributions, volunteers, Prasad, and tickets.
• Google — if you sign in via Google OAuth, your basic profile (name, email, photo) passes through Google's systems as per their policy. We do not store your Google credentials.
• Twilio — if you sign in or verify via SMS OTP, your phone number is used solely to deliver the one-time code, via Twilio Verify.
• Cloudflare — as our infrastructure provider, your data resides in their D1 database and R2 storage. Cloudflare cannot read or use your data for their own purposes.
• ZeptoMail — your email address is used solely to deliver transactional receipts. No marketing.
• Fonnte — your WhatsApp number is used solely to deliver payment confirmations, Prasad passes, and event updates if you have opted in, and to operate our WhatsApp helpline bot.
• Anthropic (Claude AI) — if you send our WhatsApp helpline bot a question outside its standard menu, that message's text may be sent to Anthropic's Claude model to generate a reply. The bot is restricted to answering questions about this event only, and every AI-generated reply is labelled as automated.

5. Payments & Refunds

Contributions may be made via UPI or through an integrated payment gateway. We do not collect or store any card numbers, bank account details, net-banking credentials, or CVV. Any payment data entered through a gateway is processed securely by the gateway provider and is subject to their privacy policy.

5.1 Refund of Contributions

If a resident needs to withdraw their contribution, a refund can be considered — provided the corresponding payment can be verified in our records. A refund request is only actionable when there is a confirmed, traceable payment to match it against.

To request a refund, contact the committee on WhatsApp with your name, flat number, and the UPI transaction reference. The committee will verify the payment and process the refund at the earliest.

6. Your Rights

As a PSOTS resident, you are always welcome to:

• Ask us what information we hold about you.
• Request a correction if anything is inaccurate.
• Have your name removed from the public contributors list.
• Delete your name, email, and phone from your profile, RSVP, volunteer sign-up, and tickets at any time via My Profile → Delete My Data in the portal — contribution amounts are kept for accounting, with your name removed.
• Remove yourself from the committee's general WhatsApp broadcast list (announcements, event reminders) at any time via the Subscribe page — note this doesn't affect transactional messages like payment confirmations, Prasad passes, or ticket replies, which go out based on your contribution/registration.
• Sign out to clear your local session from this device.

For any of the above, reach us on WhatsApp: 9482088904 or 9902837002.

7. Children

This Site is intended for adult residents of PSOTS. We do not knowingly collect personal information from anyone under 18 without a parent or guardian's involvement.

8. Updates to This Policy

If we ever need to update this policy, changes will be posted here with a revised date. We will not make changes that reduce your privacy without informing the community first.
