Privacy Policy

Common Charts collects only the information needed to run the app and improve the service.

Information We Collect

• Account information such as your Firebase account ID, email address, and display name.
• Chord chart files, extracted text, and generated cleanup results when you upload PDFs or use AI cleanup features.
• Planning Center account connection details, including your Planning Center user ID and encrypted refresh token, if you connect Planning Center.
• Subscription, entitlement, and credit information used to manage Plus access and monthly allowances.
• App analytics events, such as onboarding step views, skips, sign-in method, Planning Center connection, imports, and Plus offer actions.
• Basic technical data such as request logs, timestamps, and network information used for security, abuse prevention, and diagnostics.

How We Use Information

• To sign you in and keep your account working.
• To process chord charts, generate cleaned output, and return results inside the app.
• To manage Planning Center connections, credits, subscriptions, and account recovery flows.
• To understand where onboarding works or gets abandoned, without collecting chart text, song titles, or account identifiers in analytics events.
• To monitor service health, prevent abuse, and improve performance and reliability.

Third-Party Services

Common Charts relies on third-party services to operate, including Firebase for authentication, Planning Center for connected account access, Firebase Analytics for app usage analytics, RevenueCat for subscription status, and Google Cloud Vision for positioned text extraction, Google Gemini and Moonshot AI models for independent chart verification, and OpenRouter for model routing where configured. Information needed to complete those features may be shared with those providers.

Data Storage

Planning Center refresh tokens are stored in encrypted form. Verified chart-conversion results and compact OCR evidence may be cached in encrypted form for up to 30 days for the same signed-in user; source PDF and image files are not stored in that cache and cached results are never shared between users. Other account, billing, and operational records may be stored as long as needed to run the service, maintain account history, and meet legal or security obligations.

Your Choices

You can disconnect Planning Center from the app at any time. If you want to ask about access, correction, or deletion of account data, email support@30twelve.org.

Optional import problem reports

When you choose to report an import problem, we receive technical diagnostics (import source, processing stage, error and request identifiers, app/build and operating system versions, page count and file size) and any note you provide. Chart content, filenames, credentials and private URLs are excluded from diagnostics. Chart files are shared only when you enable Include chart files; the app lists those files before submission.

Reports require sign-in to deliver. Pending reports stay on your device until delivery is confirmed; you may cancel queued reports. Reports and optional attachments are accessible only to authorized administrators through our private admin website. We delete them after 30 days or when you delete your account. Sending a report does not use conversion credits and does not promise an individual repair or response.
