License Center

Track Factory handles trials, purchases, activation codes, restoration, and device migration through the License Center. With a valid license all splitting features are available; when the license is not ready, reading and splitting pause while your signed-in account and existing data are untouched.

The app interface is in Chinese; on-screen labels are quoted so you can follow along.

Opening the License Center

Sign in as this app's administrator, then click 授权中心 (License Center) at the top right. Ordinary NAS accounts have no purchase, redemption, backup or platform-account maintenance entry; ask the app administrator. fnOS system-administrator status does not grant those rights. The panel shows your current state:

• 软件已激活 (Software activated): a time-limited paid license is available, with its expiry shown.
• 已获得永久授权 (Lifetime license granted): a permanent license is available.
• 免费试用体验中 (Free trial): the trial is available, with its remaining time shown.
• 授权未激活 (License inactive): connect Leelaa to find a purchased license, or redeem an activation code.
• An administrator can use 打开授权中心 (Open License Center) in the 授权未就绪 (License not ready) banner. Ordinary accounts see a message to contact the app administrator.

Follow entries actually offered by your installed version. If an older version lacks My licenses or backup tools, retain its data and check the installed version; do not clear its identity to find a new button. Plans, prices and purchase availability come from the actual official page.

Trial

• The first time you open the License Center you can start a trial; the trial length is decided by the credential the license service issues and this app verifies — the panel shows the days remaining.
• When the trial expires, features pause; files already written are unaffected. Access resumes after this app verifies the credential and shows licensing as available.
• The trial is bound to your device and cannot be reset or bypassed by going offline; when it ends, purchase or redeem.

Purchasing

1. Click 我的授权 (My licenses) in the License Center, follow the link to sign in to the official store, and confirm the current device.
2. Click 购买授权 (Buy a license). Check the current plans and prices on the Track Factory page and pay.
3. Confirm the original order is paid in the store, then return to the app and click 刷新我的授权 (Refresh my licenses), choose 使用此授权 (Use this license), and confirm the target device on the official site.
4. Click 刷新进度并继续领取 (Refresh progress and continue claiming). Wait for verification and durable installation; 软件已激活 (Software activated) or 已获得永久授权 (Lifetime license granted) confirms success.

The official store retains orders and purchased entitlements. Payment, connecting an account, or completing a request still requires the license claim to finish. Return to the current operation to retry after a network interruption.

Redeeming an activation code

1. Choose 兑换 (Redeem) in the License Center.
2. Enter an activation code that belongs to Track Factory (letters, digits, and hyphens, within the form’s accepted length).
3. The license service verifies it. If you see 激活码未被接受，请核对后重试 ("activation code not accepted; check and retry"), check for typos and that the code is for this product.
4. Once verified, the panel shows 软件已激活 (Software activated) or 已获得永久授权 (Lifetime license granted), depending on the license.

Finding a license or replacing a device with your account

If the license belongs to your Leelaa account, you can find it without old app data or a backup file:

1. On the reinstalled app or new device, complete the local administrator's first login and password change. Open 授权中心 → 我的授权 (License Center → My licenses) and follow the connection prompts.
2. Sign in to the original account on the official site. Check the product, target device, and verification code before approving. Return to the app and click 我已确认，继续连接 (Confirmed; continue connecting).
3. Under 我的授权 (My licenses), use the offered action: 恢复到本机 (Restore to this device), 迁移到本机 (Migrate to this device), or 使用此授权 (Use this license). Confirm the actual target on the official site. A license already active here shows 使用中 (In use) and needs no repeat migration.
4. Wait for review if required, then click 刷新进度并继续领取 (Refresh progress and continue claiming). Success displays 当前设备的授权已核验并保存，可以继续使用 (This device's license has been verified and saved) and 软件已激活 or 已获得永久授权 in the main panel.

The license service decides approval, waiting time, and migration frequency. Migration does not extend the original expiry, and the old device becomes invalid according to the service's revocation rules. Disconnecting Leelaa retains the installed license and the local administrator login; a platform account does not replace the app administrator.

Importing an account recovery archive

.llab is an account archive exported from the official store. Connect the same Leelaa account used for export. Under 我的授权 (My licenses), click 导入授权档案 (Import a license archive), select the file, enter its password, and click 校验授权文件 (Verify license file). After inspection, choose 恢复到本机 (Restore to this device), confirm on the official site, and return to claim the license.

The app sends the encrypted archive and entered file password to the official Auth service for inspection. Restoration still requires the original account's confirmation and a live entitlement check. Damaged files, a different owner, expiry, or revocation prevent restoration. Use the respective import entry for .llab archives and the .lltf local backups below.

Backing up a license

Before deleting app data, open 授权中心 → 备份与恢复 → 备份授权 (License Center → Backup and restore → Back up license) to export a .lltf for restoration on the original device:

1. Enter the current administrator password for this app.
2. Set a file password of at least eight characters and confirm it.
3. Click 导出授权备份 (Export license backup) to download the .lltf file. Keep the file and its password separately in safe locations outside the app directory.

The backup contains only what is needed to restore this product's license. It does not contain the administrator password, directory settings, task history, or audio. A forgotten file password cannot be recovered; export a new backup instead. The file has no separate short expiry, while the original license expiry and revocation still apply.

Restoring on the same device

When reinstalling with app data retained, the app continues reading its existing license record. If the data was deleted, install on the same device, complete the administrator's first login and password change, then open 备份与恢复 → 恢复授权 (Backup and restore → Restore license):

1. Select the exported .lltf file and enter its file password.
2. Click 恢复授权 (Restore license). The app inspects the file before checking the license online.
3. The app checks the original license and device binding online. Success displays 已恢复本机授权 (License restored on this device).

Use 软件已激活 (Software activated) or 已获得永久授权 (Lifetime license granted) as confirmation; refresh the panel if needed. Restoration requires connectivity, a valid system clock, and a license that has not expired or been revoked. Use the Leelaa account flow above when replacing a device or when its identity has changed. Import does not overwrite an existing license or order record, and it does not recover deleted administrator accounts, configuration, or history.

Before uninstalling

Before choosing to delete app data, confirm that you can sign in to the Leelaa account that owns the license, or keep the local .lltf backup and its file password. Separately save any configuration, history, or output files you need. System uninstall options determine whether app data and shared directories remain; the uninstall script does not proactively delete source media. Recovery after a wipe requires account confirmation or a local backup, rather than a device ID alone.

Your license and your data

• License problems never clear your sign-in, source audio, written files, or task history.
• A revoked license blocks new tasks, and running tasks stop automatically (授权状态已变化，处理已停止 — "license status changed; processing stopped"); completed files are kept.
• License state lives in the app's own data. License import does not overwrite retained data or settings; deleted data must be recovered separately or configured again.

For anything not covered above, contact support and include the exact message text shown in the License Center.
