> Draft for review. The effective date and product-specific receipt through the shared contact channel require confirmation. Do not publish this draft as final terms.
Purpose
DrumsCore helps you create, edit, and practice drum charts using notes you enter and audio you provide. The app builds drum notation from the instruments and positions you enter, and plays it with built-in drum sounds. Version 1.0 does not include automatic transcription from audio or stem separation. Check your notes and any BPM estimate before using them.
Rights to audio and charts
Use material that you have the rights to use, copy, export, and share. Importing or exporting a file does not grant permission to use another party's recording, composition, or chart.
Free and subscriptions
Free allows up to three songs (including the sample), including archived songs. You can edit or delete the sample. Deleting it frees one song slot; duplicates also count as songs. Note entry, editing, audio, practice, speed, and song length have no additional Free limits.
Monthly and yearly DrumsCore Pro plans remove the song limit and provide PDF, MIDI, editable-song, and library-backup export, plus optional iCloud sync. There is no free trial. See the purchase screen for your price and billing period. Purchases are charged to your Apple Account, and subscriptions renew automatically.
Use Apple's subscription settings to manage or cancel a subscription. Refund requests follow Apple's process and are subject to Apple's conditions.
After Pro expires
Existing songs on your device remain editable and playable. Adding songs is restricted when you have three or more songs, including the sample; export and iCloud sync stop. When sync resumes, differing versions may be kept separately to protect your work.
Storage and sync
Edits are stored on your device. iCloud sync requires your Apple Account, a network connection, and available storage. Audio transfers require an explicit action. Sync is not a guarantee of backup or collaborative editing. Keep a separate copy of important work using available export options.
Privacy and contact
See Privacy for data handling and Support for contact information.
Decisions required before publication
Confirm the effective date and required regional disclosures. The operator and shared contact channel are established. The relationship to Apple's standard EULA was confirmed in App Store Connect on September 30, 2026. No unapproved liability limits, governing law, or jurisdiction clauses have been added.

Draft verification status (October 10, 2026)
The primary device is iPad; the Mac Catalyst and iPad versions are planned to launch together. Existing decisions on the operator, shared contact channel, retaining inquiries only as needed and deleting unneeded personal information remain in place. Canon records dated September 30 report the standard Apple EULA shown in App Store Connect, GA retention settings, the Sentry US region, and the user's confirmation of relay delivery. These are dated records, not administration settings reverified in this work. In-app delivery on physical devices, SDK retention and deletion operations, the effective date, and public URLs remain separate checks. A dedicated sample song and transcribed data are planned; materials, rights, and integration are not complete.
