Who operates Pianu?

Your AI LLC operates Pianu. For questions about your data, email support@pianu.app.

Accounts and service usage

When you sign in, our account service stores the email address used for login. The service records processing metadata to check access, run the service, and diagnose errors.

Songs, players, and Goals

The app keeps songs, player details, Goals, and progress on your device. Songs can sync through iCloud under your Apple Account. Data on your device and in iCloud is separate from your Pianu service account.

Sheet-music scan photos

The score transcription service receives a scan image and processes it in memory to return a score. That service does not keep an image library after processing. Service usage records are separate from the image. This description does not apply to images saved as Chat attachments.

Chat and AI requests

Chat history is saved on the device for the signed-in account. It can include message text, player context, and attached images. A request sends the conversation and relevant attachments to the configured AI service to produce a reply or result.

AI score and cover tools also send the content needed for the request to an AI service. Do not include information you do not want sent for processing. Saved local Chat attachments are not covered by the scan service's temporary-image behavior.

Service providers

Pianu uses Supabase for accounts and service records, Modal for score transcription, Cloudflare for the website and request routing, and AI providers for generated results. Apple provides iCloud and App Store purchases. These services receive the data needed for the feature you use. Their own policies also apply.

Purchases

Apple handles payment for Pianu Pro. We do not receive your payment card details. The app and subscription service use purchase information to check Pianu Pro access.

Website download measurements

When you use a download link on this site, the website records a fixed button label and a count through Cloudflare Analytics Engine. We do not put an IP address, account ID, referrer, or full URL in that event, and do not set a cookie for it. It counts outbound requests, not unique people or installs. Hosting providers also process network requests to deliver the site.

Families and children

Pianu supports young learners. An adult should manage sign-in, purchases, and content sent through Chat or AI tools. If you need help with a child's information, contact support@pianu.app.

Access and deletion

Use Delete Account in the app, or email support@pianu.app from your account address to request help with account data. Songs and Chat history stored locally, iCloud content, and Apple subscriptions are separate. Tell us which data you want removed. Manage Apple subscriptions in Settings > Apple Account > Subscriptions.

Updates and questions

We update this page when the app's data flows change. The review date below shows when this description was last checked. Contact support@pianu.app with a question or a data request.
