Privacy
Effective date: May 7, 2026. Last updated: October 2, 2026.
Prime Expeditions LLC owns and operates OnBook and is responsible for how personal information is processed as described in this Privacy Policy.
To use OnBook, you need an email address for account access. Some features may ask for optional information. For example, if you use partner invite features, you may choose to provide a display name so your partner can recognize the invitation in their app.
OnBook may process rehearsal materials you upload, line audio you record or receive, purchase information, app usage information, and diagnostic data to provide, maintain, and improve the service.
When OnBook first opens, it asks Apple whether the installation resulted from one of our Apple Ads. Apple provides a privacy-limited result, which may include campaign, ad group, keyword, placement, and whether the download is new or a redownload. We store the result with an installation-specific identifier and may associate it with your OnBook account and product usage to measure our own marketing. We do not use it for third-party advertising or cross-app tracking.
OnBook may send us diagnostic reports about some rehearsal runs to help improve recognition accuracy. These reports include the text recognized by your phone or tablet, related script text, and timing and technical details from those runs. They never include audio recordings.
We use this information to provide and improve OnBook, send product and service updates, respond to support requests, maintain security, and comply with legal obligations. We do not sell your personal information or use it for third-party advertising or cross-app tracking.
If you submit rehearsal materials in the app, they are used to provide product functionality. Speech processing and script handling are designed for sensitive audition workflows.
We retain data only as long as reasonably necessary for service operations, security, legal compliance, and legitimate business needs.
You can request access, correction, or deletion of your personal data by contacting us.
