📌 Short version: Books Listening runs entirely in your browser. Your books, notes, and reading data never leave your device. We collect no personal information.
1. What We Collect
Books Listening is a browser-based application. We collect no personal information from users of the app itself.
The following data is stored only on your device using your browser's local storage:
- Books you save to your personal library
- Your reading position and bookmarks
- Notes and pins you create
- Your voice, speed, and theme preferences
- Your license key (to verify Pro activation)
- Your trial start date
None of this data is transmitted to our servers or any third party.
2. What We Don't Collect
- We do not collect your name, email, or any account information
- We do not upload, read, or analyze your books
- We do not track which books you read
- We do not use analytics or tracking cookies in the app
- We do not sell any data — there is no data to sell
3. Purchase Information (Gumroad)
Books Listening is sold through Gumroad. When you purchase, your payment and email are handled by Gumroad under their own privacy policy. We receive confirmation of your purchase and your license key — we do not receive or store your payment card details.
Gumroad's privacy policy is available at gumroad.com/privacy.
4. The Landing Page (bookslistening.com)
Our website is hosted on HostGator. Standard web server logs may record your IP address and browser type when you visit the site — this is standard for all web hosting and is not used to identify you personally.
The landing page does not use advertising trackers, analytics pixels, or cookies.
5. Third-Party APIs Used in the App
The app optionally uses these external APIs — all are opt-in and only activated by your explicit action:
- Free Dictionary API — when you click a word to look it up. The word is sent to their server; no personal information is included.
- MyMemory Translation API — when you use the quick translate feature. The text is sent to their server; no personal information is included.
- ElevenLabs — only if you choose to connect your own API key for cloud voices. The sentence being read is sent to them so they can speak it. Your API key is stored in your browser only and is never sent to us.
- Hugging Face and jsDelivr — if you turn on offline translation or the natural voice, the language model is downloaded once from these CDNs. Only the download is requested; none of your book text is sent.
- Google Fonts and cdnjs — page fonts and the libraries that read your files load from these CDNs. As with any web request, they receive your IP address.
- Licence verification — when you activate a licence key, that key alone is sent to our verification endpoint so it can be checked. Nothing else is sent with it.
6. Children's Privacy
Books Listening is designed for general audiences. We do not knowingly collect any information from children under 13. Since we collect no personal information at all, this is inherently satisfied.
7. Changes to This Policy
We may update this policy from time to time. Any changes will be reflected on this page with an updated date. Continued use of the app after changes constitutes acceptance of the updated policy.
