Privacy Policy

Effective May 17, 2026

Panna is a Hindi classical-poetry app. It works without an account — no email, no phone, no name. This page describes what data the app sends to our servers when you use it, what we don’t collect, and how you can control it.

1. Who runs Panna

Panna is operated by Panna (Dhananjay Ghanwat), contactable at hello@panna.in. The mobile app is distributed under the package name in.panna.app.

2. The short version

No account, no email, no phone number, no name.
An anonymous device identifier is generated on first launch so your favorites and listening history can sync to our servers and survive across app updates.
We do not collect your location, contacts, photos, microphone, calendar, or advertising ID.
We use no third-party analytics or advertising trackers. Behavioural data is stored on our own servers and used only to improve the app.
You can wipe everything by uninstalling the app or asking us to delete the device's data (see §10).

3. What Panna sends to our servers

When you use the app, the following is sent to and stored on our backend:

Data	Why	Identifies you?
Anonymous device id (UUID)	Sync your favorites, listening history, compilations across app launches.	No — random, not linked to anything else.
Listening history (poem id + position + completion + timestamp)	Resume where you left off, power "Continue listening".	No
Favorites (poem id + saved timestamp)	Show your saved poems.	No
Compilations (title + ordered poem ids)	Let you build and play your own playlists.	No
Anonymous usage events (named events + small properties)	Understand which poems land, where users drop off, what to build next.	No
Push token (when opted in)	Send notifications about new poems.	No (opaque token, not your phone number).
Patronage records (amount + occasion + optional UPI reference)	Acknowledge gifts and show your support history.	No — only what you choose to enter.
Feedback you submit	Triage bug reports and feature requests.	Only if you include your contact details in the message yourself.
Platform + app version	Diagnose platform-specific bugs.	No

Note that the device identifier is a random UUID generated on your phone the first time the app talks to our server. It is not linked to your Google account, your phone number, your Android Advertising ID, or any other identifier outside Panna.

4. What we do not collect

Your name, email address, phone number, or any other contact detail.
Your precise or approximate location.
Your contacts, photos, files, microphone, or camera.
Your Google Advertising ID (Android) or IDFA (iOS).
Cross-app or cross-site tracking identifiers.

5. Cookies and tracking

Panna’s mobile app does not use cookies. The admin portal you may be reading this on stores a single httpOnly session cookie for the curator’s logged-in session — that cookie is not set for visitors of this public policy page. We use no third-party analytics, no advertising SDKs, no Facebook/Google Tag Manager, no PostHog/Mixpanel.

6. Push notifications

If you opt in to notifications, the app obtains an opaque push token from Expo’s service and sends it to our backend. We use this token only to deliver Panna-related notifications (e.g. when a new poem is published). Expo and the underlying transport (Google FCM on Android, Apple APNs on iOS) see the token but no message content beyond what the notification itself displays. You can revoke notification permission in your phone’s system settings at any time.

7. Third parties

Panna sends data outside our own infrastructure only in these cases:

Expo / Google FCM / Apple APNs — to deliver push notifications when you've opted in.
MinIO / cloud object storage — for audio file delivery. We host the storage; only you and the audio CDN are involved in the transfer.
Your chosen UPI app — when you tap a patronage donation button, the UPI deep link opens your bank's app. We do not see your bank credentials or transaction details — only the optional reference your phone returns after the transaction.

We do not sell, rent, trade, or share your data with advertisers, data brokers, or analytics vendors.

8. Audio playback

Audio recordings are streamed from our object storage to your device via short-lived signed URLs. These URLs expire after 24 hours; the audio bytes never pass through any third-party CDN we don’t control.

9. How long we keep data

Listening history, favorites, compilations, patronage records: as long as the device is active. We may purge data tied to a device that hasn't been seen for 24 months.
Push tokens: until you uninstall, deny permission, or the platform invalidates the token (after which we delete it on the next broadcast attempt).
Feedback you submit: kept indefinitely (so we can refer back to suggestions and bug history). Delete on request.
Server logs: 30 days, then purged.

10. Your choices and rights

Disable analytics in-app: Profile → Settings → toggle off "Anonymous usage data". The app stops sending behavioural events to our backend.
Disable push: revoke notification permission in your phone's system settings.
Wipe local data: uninstall the app. AsyncStorage and SQLite are cleared.
Delete server-side data: send a request to hello@panna.in with the device id (Profile → Settings shows it). We'll delete every row tied to that id within 30 days.
Export your data: same email address; we'll send a JSON dump.

11. Children

Panna is suitable for general audiences and contains no targeted advertising. We do not knowingly collect data from children under 13. If you believe a child has interacted with the service, contact us at hello@panna.in and we will delete the associated device’s data.

12. Where data is stored

Panna’s database and audio storage are hosted in India (or wherever the operator’s infrastructure provider hosts them). Push notifications are routed via Expo (United States) and FCM/APNs (global).

13. Changes to this policy

If we change anything material, we’ll update the effective date at the top and, if the change affects what data we collect, surface a notice in the app before the new collection begins.

14. Contact

Questions, deletion requests, or anything else: hello@panna.in.
