Prabhupada Vani Sync Player

Privacy policy

Last updated 5 November 2026

Prabhupada Vani Sync Player keeps the lecture audio and its transcript together on prabhupadavani.org. There are no accounts, no analytics and no advertising. Almost everything the extension keeps stays on your own device; the one thing it sends is the identifier of the lecture you are already listening to, so it can fetch that lecture's timing file.

What is stored on your device

The extension uses your browser's local extension storage for three things:

• your settings — highlight colour, playback speed, skip size, and whether the transcript follows one word at a time;
• your place in each lecture, so a lecture resumes where you stopped;
• a cache of transcript timing files, so a lecture you have opened before highlights immediately instead of waiting for a download.

This information stays in the extension's own storage on your device. It is not synced to us or to anyone else, it is not linked to an account, and removing the extension removes it.

What is sent over the network

The extension contacts its timing server at prabhupadavani-sync.bhakti.eu.org when you open a transcript page on prabhupadavani.org:

• It asks whether another recording of that lecture is known. That request includes the lecture's identifier, taken from the page address, so the server can return the right answer.
• If “Get corrected timings automatically” is on — it is on by default — it also downloads the timing files for that lecture and an index of the lectures that have corrected timings. These files are used only to move the highlight in time with the audio.

The request body contains no personal information: no page text, no account details, no advertising identifier. Two listeners on the same lecture send the same request.

The server is hosted on Cloudflare Pages. Like any web host, Cloudflare processes standard request information such as IP address, browser type and time of request in order to deliver files and protect the service. We do not use that information to identify individual listeners, and we do not combine it with anything else.

Other recordings

Some lectures are not available on prabhupadavani.org, or their tape plays silence. For those, the extension can offer a recording hosted by audio.iskcondesiretree.com. If you choose to play it, your browser loads the audio directly from that site. The extension sends nothing to that site beyond the normal request for the audio file, and that site's own privacy policy applies.

Permissions and why they are needed

• Storage — saves the settings, resume positions and timing cache described above.
• Access to prabhupadavani-sync.bhakti.eu.org — downloads the timing files and the list of alternate recordings.
• Access to 127.0.0.1 and localhost — used only by the developer's local preview tool while testing the extension. The published extension makes no requests to these addresses.

What the extension does not do

• No analytics, telemetry, advertising or tracking.
• No accounts, sign-ins or advertising identifiers; the extension sets no cookies.
• No collection of names, email addresses, health, financial or authentication information.
• No reading of your browser history or activity on other sites, and no transmission of keystrokes or clipboard contents. The only page information sent is the lecture identifier described above.
• No sale or transfer of data to third parties.
• No remote code: all of the extension's JavaScript ships inside the package. It does not download or execute scripts, modules or WebAssembly from a server.

Your choices

The pinned player, transcript following and corrected timings can each be turned off in the extension's popup. Turning corrected timings off stops the timing downloads; the extension may still ask whether an alternate recording of the lecture is known. Removing the extension deletes all locally stored settings, positions and cached timing files.

Changes to this policy

If this policy changes, the new version will be posted at this address with a new date. The extension's Chrome Web Store listing links to this page.
