From the Developer


This app is built by a solo developer who used to be an actor.


When I was acting, I spent so much time memorizing lines — studying scripts in the walk-in cooler during convenience store shifts, mumbling lines on the train. I kept thinking, "If I could just get the memorization out of the way, I could focus on making rehearsals better."


Now that I'm an engineer, I built this app for the person I used to be.


Get your lines memorized quickly, put down the script, and get to the real work of rehearsal.


That's the philosophy behind this app. It's not a replacement for live rehearsal — it's a tool to help you get more out of it.


I have absolutely no interest in collecting your data. I'm selling an app, not your information.



In Short


  • When importing scripts or generating voices, your data is temporarily sent to a server
  • It is deleted as soon as processing is complete — your scripts are permanently stored only on your phone
  • Your data is never used to train AI models
  • The developer does not view the content of your scripts


    • In More Detail


    "Will AI use my data for training?"


    Many people worry about AI using their data for training when they hear the word "AI." I completely understand that concern.


    The key question here isn't really about "security" — it's about whether the data you send is used to train AI models.


    This app uses Google's cloud voice services for voice generation, and AI services from Google and Anthropic for script parsing.


    All of these use commercial APIs, which means your data is never used for AI training. This is clearly stated in each company's API terms of service.


    For safety monitoring, submitted data may be retained in logs for up to 30 days, after which it is automatically deleted.


    "Where is my script data stored?"


    Your script text, character settings, and practice history — all of these are stored only on your phone.


    Your full script is never permanently stored on our servers. Even for temporary data during processing, the developer does not view the content of your scripts.


    Text is temporarily sent to servers for AI processing (voice generation and script parsing), but is deleted after processing is complete.


    "What happens when I share a script?"


    When you share a script using a share code, it is uploaded to a server via encrypted communication. This data is automatically and completely deleted after 48 hours.


    Sharing only happens when you explicitly choose to do so. Your data is never sent without your action.


    "What about copyright?"


    We sometimes receive questions about script copyright.


    Generally, using a script to memorize your lines is recognized as "reproduction for private use" under copyright law.


    However, sharing a script with others via the share feature may go beyond private use. What the rights holder permits varies by work and contract.


    This app is simply a tool for practicing scripts and does not manage or make judgments about copyright. Please use the app responsibly, including the share feature, in accordance with any agreements you have with your agency, production company, or rights holders.
