Purchasing ARC-24
ARC-24 uses a one-time purchase model. There is no subscription and no automatic charge after the trial.
7-day free trial
On first launch you see the paywall with two options:
- Start 7-Day Trial — full access for 7 days (free non-consumable in the App Store)
- Unlock ARC-24 — pay once and keep the app forever
When the trial ends, the app locks until you purchase the full version. Your songs on the device are not deleted, but you cannot use the app until you unlock.
purchasing-trial-ended.webpTrial-ended lock screen with unlock and restore options (no personal data in screenshot).
While the trial is active, a TRIAL · Nd badge appears in the header (days remaining).
Full unlock
Unlock ARC-24 is a single non-consumable purchase. After purchase:
- Permanent access on your Apple ID
- Restore works on new devices and after reinstall
Restore Purchase
Use Restore Purchase on the paywall or trial-ended screen if you already bought the full version (or need to sync entitlements on a new device).
- Tap Restore Purchase
- Sign in with the same Apple ID used for the purchase
- The app unlocks when StoreKit confirms the entitlement
Restore does not start a new trial.
Not a subscription
- The trial does not auto-convert or auto-charge
- There is no recurring billing
- After the trial, you choose to pay once or stop using the app
Device trial limit
Each physical device can claim the 7-day trial once. A different Apple ID on the same device cannot start another trial. The full unlock is always available regardless of trial status.
Anonymous analytics
ARC-24 sends anonymous install-level analytics to our server when you start a trial, complete a purchase, or launch the app (entitlement status only). Events include a random install identifier, timestamp, locale, and iOS version — not your Apple ID, email, or name.
