Privacy Policy

Effective: 2026-07-29  ·  Applies to Lesson Attendance & Tuition, published by goonobu.

What we collect

Nothing. Lesson Attendance & Tuition does not have user accounts, does not use advertising or analytics SDKs, and does not contain an external AI or backend service. No usage data, device identifiers, or student and payment records are transmitted to us or any third party.

Where your data lives

All records you create — student rosters, lesson attendance, charges, payments, and generated PDFs — are stored only in the app's local database on your device. Nothing syncs to iCloud or any server operated by us or a third party.

How to delete your data

You can delete any student or ledger entry individually from its list view within the app. Deleting the app from your device removes all locally stored records. If you previously exported a backup or PDF, that file remains wherever you saved it (Files app, iCloud Drive, etc.) and is not affected by deleting the app — delete it separately if you want it gone.

Exported PDFs

Receipt and statement PDFs are generated on-device and exported only when you use the standard iOS share sheet. You choose the destination, and we never receive a copy.

Payments

The one-time in-app purchase is processed entirely by Apple through StoreKit. We do not receive your payment details. Apple's own privacy policy governs that transaction. Separately, tuition payments recorded in your ledger are amounts you enter yourself — the app does not process or transmit any student payment.

When the app does use the network

Lesson Attendance & Tuition otherwise works fully offline. Network activity happens only in two cases: (1) tapping a Terms of Use or Privacy Policy link opens Safari, and (2) purchasing or restoring the in-app purchase communicates with Apple's payment system. No other network activity occurs.

Children

Lesson Attendance & Tuition is a business tool for teachers and is not directed at children, even though student names may be entered by the teacher using the app.

Changes

If this policy changes, the new version will be posted at this same URL with an updated effective date.
