Use Hearleaf with care.

Testing purpose

Hearleaf is pre-release software offered so readers and creators can evaluate Library page capture and review, Studio script editing, synced web storage and audio export, authorized-voice narration, caching, and playback. Features, quotas, capacity, storage limits, formats, and availability may change. Test data may be reset, and a feature that works in one build may be changed or removed.

Web Studio account

Web Studio requires Google sign-in. Google shares your name, profile picture, and email. Hearleaf Studio uses only your name and email, does not display or copy the picture into Studio records or content storage, and does not access contacts, Drive, calendar, or other Google services. Firebase Authentication may retain the provider picture as account metadata. Keep access to your Google account secure. Current web Studio storage is limited to 1 GiB per account; clear generated block, project, or account audio when needed.

Use material you are allowed to process

Use Hearleaf only with pages, books, handouts, images, manually entered scripts, and other text that you own, created, have permission to process, or may lawfully use. Access to a physical or digital copy does not automatically give you the right to redistribute its text or generated narration.

Do not use Hearleaf to infringe copyright, bypass access controls, distribute unauthorized copies, or process unlawful content. You remain responsible for the material you submit and for how you use or share any resulting audio.

Use only authorized voices

Use your own voice, or a voice whose speaker knowingly gave you explicit permission to record and use it for Hearleaf listening, creation, and export. Permission for one purpose does not imply permission for advertising, publication, impersonation, or another purpose.

• Do not record or use a person's voice secretly or without informed permission.
• Do not impersonate, deceive, defraud, harass, threaten, or misrepresent another person.
• Do not defeat or work around voice authorization, security, quota, or abuse controls.
• Stop using a person's voice if that person withdraws permission.

AI-generated audio

Hearleaf narration is synthetic AI-generated speech. It can contain pronunciation, transcription, pacing, or other errors. Review the source material when accuracy matters. If you share or publish generated audio, you are responsible for permission to use both the voice and the underlying material and for any AI-generated-audio disclosure required by the destination platform.

Do not present generated audio as an authentic recording of the speaker or use it as proof that a person said, approved, signed, or agreed to something.

Exports and third-party destinations

Studio can create a messaging-compatible M4A copy or an exact WAV master. Android passes it through the native share sheet; web Studio uses browser sharing when available and otherwise downloads it. Export files are temporary and Hearleaf keeps no export history. Android share copies remain in its app cache for up to 24 hours. Hearleaf does not control that destination, its upload, or its later use of the file. Review the destination's terms, rights, privacy, and disclosure rules before sharing or publishing.

Reasonable testing limits

Do not overload, probe, reverse engineer, disrupt, scrape, or misuse the service, and do not automate requests in a way that defeats normal app controls. Hearleaf may limit, suspend, or end test access to protect users, voices, reading material, cloud capacity, or the service itself.

Privacy, synced storage, and local copies

The Privacy Policy explains what is stored locally, what is sent for voice authorization and audio preparation, what web Studio syncs with your account, and how to delete it. Keep your own copy of important material. Do not rely on Hearleaf as the only storage location for a book, page, creator project, script, voice recording, or generated audio.

Availability and warranty

Hearleaf is provided as available for evaluation during Open Testing. To the extent permitted by applicable law, no promise is made that the test will be uninterrupted, error-free, compatible with every device, or suitable for a particular purpose. Do not rely on it for emergencies, safety-critical work, or the sole means of accessing essential information. Nothing here limits consumer or other legal rights that cannot lawfully be limited.

Changes and ending participation

These terms may be updated as the test changes. A material update will receive a new effective date on this page. You may stop participating by removing local Android data or by using Delete account in web Studio after fresh Google confirmation. Further deletion guidance is available in the Privacy Policy.
