Privacy policy

Last updated November 10, 2026

Expurgate mutes or bleeps profanity in audiobooks while you listen. This page explains what the Expurgate website, Chrome extension and Android app collect, and what they don't.

What stays on your device

• Your settings: filter on/off, mute style, chosen word categories, timing adjustment and button position are stored in your browser or phone.
• Filtering itself happens on your device. Expurgate does not record, upload or store the audio you listen to, and it does not host or stream audiobooks.

What we receive

• Filter lookups. To load the filter for a book, the extension or app asks our server for that book's filter file. This request includes the book's identifier or title and your IP address, which any web request carries.
• Book requests. If you ask us to add a book, we store the title and author you submit, and how many people asked for it.
• Email address. If you join the waitlist, or enter an email in the extension, we store that address to contact you about Expurgate access.
• Account sign-in. If you sign in to the Expurgate web app with an Audiobookshelf account, we handle your sign-in only to give you access and keep your library connection working.
• Payments. Subscriptions, when offered, are processed by Stripe. We never see or store your card number; we only receive confirmation that a subscription is active.

Third-party services

• Open Library. The extension looks up book covers by sending the book's title and sometimes its author to openlibrary.org, and loads the cover image from covers.openlibrary.org.
• Cloudflare. Our website and server connection run through Cloudflare, which processes requests to deliver them securely.

What we don't do

• We don't sell your data or share it for advertising.
• We don't use analytics or tracking scripts on this website or in the extension.
• We don't read pages outside the audiobook sites the extension lists in its permissions.

Keeping and deleting data

We keep waitlist emails and book requests until you ask us to remove them. To delete your data, email us from the address you signed up with. Uninstalling the extension or app removes the settings stored on your device.

Children

Expurgate is not directed at children under 13 and we do not knowingly collect their information.

Changes

If this policy changes, we'll update the date above.
