Activate Pro (Redeem License Key)
Activation means removing the daily transcription limit with a license key after purchase. Once activated, the current device can transcribe without the daily cap.

How to Activate
- After purchasing Pro, you will receive a license key (in
OS-xxxx-xxxx-xxxx-xxxxformat). - Open OnceScribe → Settings → License.
- Enter the license key and click Verify / Activate.
- Once activated, the UI will show “Activated” along with the validity period, and the daily transcription limit will be removed.
The activation state is written to local config and refreshes the front-end License Store, so Pro remains active while offline as long as the license has not expired.
Device Slots & Management
A Pro license supports multiple device bindings. On the Settings → License page you can see:
- Machine ID: the unique identifier of the current device
- Device slots:
{used} / {max}devices used - Bound device list: device names and unbind actions
When the device limit is reached, activating on a new device will show “Device limit reached”. You must unbind an old device first.
Unbind Devices
Unbind This Device
In Settings → License, click Unbind this device and confirm. This will:
- Remove the current device from the license’s bound device list
- Revert the local Pro state to Free
- Free up one device slot for a new device
Unbind operations are rate-limited by the server. If you see “Unbinding too frequent”, please try again later.
Unbind Another Device
In the bound device list, click the delete button next to another device to remotely unbind it. This does not affect the Pro status of the current device.
Restore Purchase
Cross-Device Recovery (CDKey)
Enter the same license key on the new device to restore Pro. If the device limit is reached, unbind an old device first on any previously bound machine.
IAP Purchase Recovery
Currently OnceScribe primarily uses license-key authorization. If App Store / Microsoft Store versions are added in the future, the app will automatically query and restore store purchases on launch.
Common Errors & Solutions
| Message | Cause | Solution |
|---|---|---|
| License key not found | The CDKey does not exist in the system | Check that the key is entered completely, including hyphens, and watch for case sensitivity |
| Device limit reached | The license is already bound to the maximum number of devices | Unbind an old device from the list, or contact support to expand the limit |
| License key expired | The CDKey has passed its validity period | Contact your purchase channel or support for renewal |
| Unbinding too frequent | Server-side unbind cooldown | Try again later, or contact support for assistance |
| Network error | Cannot reach the license server | Retry after checking your connection; the client will automatically fall back to a backup domain if the primary is unreachable |
Notes
- A license key is bound to the current device once verified. Do not share it with others.
- When switching devices, unbind the old device first, then activate on the new one.
- OnceScribe Pro is a digital product and is non-refundable. Please try the Free tier before purchasing.
