Call for Line

Effective Date: April 8, 2026

This Privacy Policy explains how Call for Line LLC ("Call for Line," "we," "us," or "our") collects, uses, and protects your information when you use the Call for Line mobile application (the "App"). We’ve written this in plain English because we believe you deserve to know exactly what happens with your data.

1. Information We Collect

Information You Provide

Account information. When you sign in through Apple Sign-In or Google Sign-In, we receive your name, email address, and profile photo from those services. This is managed through our authentication provider, Clerk.
Scripts. You upload scripts as PDF or text files for parsing into scenes and dialogue.
Voice recordings. When you rehearse, the App records your voice to transcribe your lines and score your accuracy.
Rehearsal preferences. Your character selections, accuracy goals, speed settings, and hint preferences.

Information Collected Automatically

Device identifier. We generate a unique device ID the first time you sign in, which is linked to your account.
Basic device information. Device type, operating system version, and app version.
Usage metrics. How you interact with the App (e.g., which features you use, session length). We collect these through our own systems–we do not use any third-party analytics SDKs.

Information We Do Not Collect

We do not use third-party advertising or ad-tracking tools.
We do not use cookies (the App is a native mobile application).
We do not collect precise location data.
We do not sell your personal information. We have never sold personal information and have no plans to.

2. How We Use Your Information

We use your information only to provide and improve Call for Line. Here’s specifically what that means:

Script parsing. Your script text is sent to our processing tools to identify scenes, characters, and dialogue.
Voice generation. Individual lines from your script are sent to our voice generation tools to create scene partner audio for your rehearsals.
Transcription and scoring. Your voice recordings are sent to our transcription tools, which convert your speech to text so we can compare it against the script and score your accuracy.
Account management. Your account information is used to authenticate you and maintain your account.
Service improvement. Usage metrics help us understand which features are working well and what to improve. We analyze this data in aggregate–not at the individual level.
Communications. We may use your email to send you important service updates (not marketing, unless you opt in).

3. How Our Technology Partners Process Your Data

Call for Line relies on specialized third-party services to power its core features. Here’s exactly what goes where:

Important: We use the API (business) tiers of these services, which have contractual commitments not to use your data for model training. Your scripts and recordings are not used to train anyone’s systems.

4. What We Store and What We Don’t

Not all data is treated the same. Here’s the distinction:

Transient Data (Processed and Discarded)

Short scripts (under 20 pages) are sent to our parsing tools, processed, and discarded. The raw script text is not retained on our servers.
Voice recordings are sent to our transcription tools in real time and discarded immediately after processing. We never store your voice recordings on our servers.
Individual script lines sent for voice generation are processed and not retained.

Persistent Data (Stored)

Account information (name, email, profile photo) is stored in Clerk and our database for as long as your account exists.
Longer scripts (20 pages or more). To avoid re-parsing the same lengthy script every time it’s uploaded, we store a copy of the script text along with its parsed structure (scenes, characters, dialogue) in our database. These cached copies are not linked to individual user accounts–they are used solely for deduplication so that processing a 40-page play doesn’t have to happen from scratch each time.
Parsed script structures for all scripts (the scenes-and-dialogue breakdown) are cached in our database alongside the stored script text for deduplication purposes.
User records (your account ID, device ID, and account preferences) are stored in our PostgreSQL database hosted on Railway.

Data on Your Device

Scripts, rehearsal progress, and generated audio are stored locally on your device using the App’s local storage. This data is under your control and stays on your device unless you uninstall the App.

5. Data Security

We take reasonable measures to protect your information:

All data transmitted between your device, our servers, and third-party services uses HTTPS encryption.
Authentication is handled by Clerk, which provides industry-standard security for sign-in and identity management.
Our database is hosted on Railway with standard infrastructure security protections.
We limit employee access to personal data to those who need it to operate the service.

No system is perfectly secure. We cannot guarantee absolute security, but we are committed to protecting your data using commercially reasonable practices.

6. Your Rights and Choices

All Users

Access. You can view the personal information associated with your account in the App’s settings.
Deletion. You can delete your account through the App’s settings. This will remove your Clerk authentication record and your user data from our PostgreSQL database. Cached scripts and parsed structures (which are not linked to your account) may persist for deduplication purposes. Data stored locally on your device will remain until you uninstall the App.
Correction. You can update your account information through your Apple or Google account settings, which will sync to Call for Line through Clerk.
Data Portability. You can request a copy of your personal data by emailing us at support@callforline.com.
Withdraw Consent. You can stop using the App at any time. For microphone access, you can revoke permission in your device’s settings.

California Residents (CCPA/CPRA)

If you are a California resident, you have additional rights under the California Consumer Privacy Act, as amended by the California Privacy Rights Act:

Right to Know. You can request details about the categories and specific pieces of personal information we’ve collected, the sources of that information, our business purpose for collecting it, and the categories of third parties with whom we’ve shared it. Under the 2026 regulations, this right extends to data collected going back to January 1, 2022.
Right to Delete. You can request that we delete your personal information, subject to certain exceptions (e.g., completing a transaction, security, legal obligations).
Right to Correct. You can request correction of inaccurate personal information.
Right to Opt Out of Sale/Sharing. We do not sell or share your personal information for cross-context behavioral advertising. If this ever changes, we will provide a clear opt-out mechanism.
Right to Limit Use of Sensitive Personal Information. We only use sensitive personal information (such as your account credentials) as necessary to provide the service.
Non-Discrimination. We will not discriminate against you for exercising any of these rights.

To exercise your California privacy rights, email us at support@callforline.com. We will verify your identity before processing your request and respond within 45 days as required by law.

Categories of Personal Information (CCPA Disclosure)

In the preceding 12 months, we have collected the following categories of personal information as defined by the CCPA:

Identifiers: name, email address, device ID.
Internet or electronic network activity: App usage metrics, device information.
Audio information: voice recordings (processed transiently, not stored).
Inferences: rehearsal accuracy scores derived from your voice recordings.

We have not sold any personal information. We have disclosed personal information to service providers (Anthropic, OpenAI, Clerk) for the business purposes described in Section 3.

7. Children’s Privacy

Call for Line is not directed at children under 13. We comply with the Children’s Online Privacy Protection Act (COPPA), as amended effective April 22, 2026.

We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without verifiable parental consent, we will take steps to delete that information as quickly as possible.

Users between 13 and 18 may use Call for Line with the consent of a parent or legal guardian. Because voice recordings are processed transiently and not stored, and because we do not use persistent identifiers for tracking or advertising, we believe our data practices are consistent with COPPA’s requirements for transient data use.

If you believe a child under 13 has provided us with personal information, please contact us at support@callforline.com.

8. Voice Recordings and Biometric Data

We want to be transparent about how we handle voice recordings, given the sensitivity of audio data and the evolving legal landscape around biometric information.

What we do: When you rehearse, the App captures your voice, sends the audio to OpenAI’s Whisper service for transcription, and receives text back. The audio is processed in real time and discarded. We do not create, collect, or store voiceprints or any biometric identifiers derived from your voice.

What we don’t do: We do not analyze your voice for identification purposes. We do not create speaker profiles. We do not use voice data for any purpose other than transcribing your rehearsal lines and scoring accuracy.

Illinois Residents (BIPA): The Illinois Biometric Information Privacy Act regulates the collection of biometric identifiers, including voiceprints. Because we do not extract, store, or use voiceprints or any biometric identifiers from your voice recordings, we believe our practices fall outside BIPA’s scope. If you have questions about how we handle voice data, please contact us at support@callforline.com.

9. International Data Transfers

Call for Line is operated from the United States. Our servers, database, and third-party service providers (Anthropic, OpenAI, Clerk, Railway) are all based in the United States. If you use Call for Line from outside the United States, your data will be transferred to and processed in the United States, which may have different data protection laws than your country.

By using Call for Line, you consent to the transfer of your information to the United States. We apply the same privacy protections to all user data regardless of where it originates.

10. Data Retention

Account data is retained for as long as your account is active. When you delete your account, we delete your Clerk record and PostgreSQL user data within 30 days.
Short scripts (under 20 pages) and voice recordings are not retained on our servers–they are processed transiently and discarded.
Longer scripts (20+ pages) and their parsed structures are stored in our database indefinitely for deduplication purposes. These are not linked to individual user accounts.
Usage metrics are retained in aggregate form. Individual-level usage data is deleted within 12 months of collection.
Device-local data (scripts, progress, audio cache) persists until you uninstall the App.

11. Third-Party Links and Services

The App may contain links to third-party websites or services. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies before sharing information with them.

12. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When we make material changes, we’ll notify you through the App or by email at least 30 days before the changes take effect. The “Effective Date” at the top of this page reflects the date of the most recent update.

We encourage you to review this Privacy Policy periodically. Your continued use of Call for Line after the effective date of an updated Privacy Policy means you accept the changes.
