Terms

Last updated October 28, 2026

These terms cover your use of Bookbubble, a service of Performance Improvement Platform LLC. By making an account or using the app you agree to them.

What you get

Bookbubble is a web app that reads PDF files aloud with highlighted words. A subscription gives you access to the app while it is active.

Subscription and payment

• The price is shown on the home page and is billed monthly through PayPal until you cancel.
• If we offer a free trial, you are charged the monthly price when the trial ends unless you cancel first.
• You can cancel at any time from your account page or inside PayPal. Cancelling stops future charges, and you keep access until the end of the period you have paid for.
• If you think you were charged by mistake, contact us and we will look into it.

Your files and your voice accounts

• You are responsible for having the right to listen to the PDFs you open.
• If you add an ElevenLabs key, that account is between you and ElevenLabs. ElevenLabs bills you directly and their terms apply to it. We aren't responsible for their charges, limits, or availability.
• Keep your key private. It is saved in your own browser.

Using it fairly

Don't share your login, try to break or copy the service, or use it to break the law.

No guarantees

We work hard to keep Bookbubble running, but it is provided as is. Reading quality depends on the PDF and on the voice you choose, and some phones limit audio when the screen is off. We may change or stop the service, and if we end it we will stop billing you.
