When you buy a licence on yojika.com, your licence key is sent to your email. Enter it in the app to unlock Yojika on this device. This page covers the Activate Yojika screen.
Where the key comes from
You buy your plan on the yojika.com website. After payment, you get an email with a key that looks like YJK-XXXX-XXXX-XXXX. Keep this email safe.
Enter your key
On the Activate Yojika screen:
- Type your License key (for example
YJK-XXXX-XXXX-XXXX). - Type the Email the key was sent to.
- Click Activate.
You need the internet once to activate. After that, Yojika works fully offline.
After activating
When the key is accepted, the app unlocks and takes you into Yojika. A Desktop or Mobile licence covers one device; a Combo licence covers two devices in total — two computers, two phones, or one of each. Activating one device more than your plan covers releases the device that has gone longest without checking its licence — each device checks about once a week while the app is open and the device is online, and entering the key counts as a check too, so it is normally the device you have gone longest without using that goes. That device stops working the next time it checks its licence: at its next start if Cloud Sync is on, otherwise within about a week. Until then it keeps working, so a device that stays offline is not signed out — but its slot is already gone, and staying offline does not protect it. To use Yojika on another computer or phone, see Manage your licence and plan.
If it does not activate
The screen tells you what went wrong:
- This license is still expired — your licence has run out. Renew it on yojika.com, then activate again with the renewed key.
- This license is registered to another device — what to do depends on your plan. On a paid one-device plan, re-enter the same key here to move the licence; the other device is signed out at its next licence check (at its next start if Cloud Sync is on, otherwise within about a week). On the Combo plan a second device simply activates, so you should not see this; a third activates too, and releases whichever device has gone longest without checking its licence. A free trial cannot be moved.
- Check the key and email — make sure the key and email match exactly what is in your purchase email. If it still fails, contact support.
Reaching this screen later
You can also open this screen from the Welcome to Yojika screen by clicking I have a license key. If you are already using Yojika (for example on a trial) and want to enter a paid key, you do not need this screen — use Settings instead. See Manage your licence and plan.
