License keys
A license key activates Premium after a web purchase. It also lets you use a Google Play purchase on a device signed in to another Google account. The app calls it an entitlement token.
Offline use
Keyguard verifies a license key on the device, so the key works offline.
- A lifetime key unlocks premium with no end date.
- A subscription key unlocks premium until its paid-through month ends.
When online, Keyguard checks the license status with the license server. If the check fails, Keyguard keeps the last known status. After a subscription renews, the check can return an updated key, and Keyguard stores it.
Privacy
A license key holds a license ID, the tier, the purchase type and, for a subscription, the paid-through month. The license server only validates purchases and checks license status. Your vault items, passwords, passkeys, notes and attachments never reach it.
Buy a lifetime license on the web
Use these steps when the Purchase page offers web checkout.
- Open the Purchase page.
- Select Buy lifetime license.
- Complete payment in Paddle.
- Keep the tab open until your key appears.
- Select Copy key or Download key.
The key is not sent by email. Save it in a secure place before closing the tab. Refreshing the same tab restores the checkout while its session is valid. If payment is still being confirmed, select Check payment status.
Create a key from Google Play
On the device with the purchase, while online:
- Open Settings > Keyguard Premium.
- Select Obtain entitlement token. Keyguard verifies the purchase with Google Play and shows the key under the option.
- Copy the key.
Use a license key on another device
- Open Settings > Keyguard Premium.
- Select Link existing entitlement token.
- In Entitlement token, paste the key.
- Select OK. If the key is valid and active, premium unlocks.
Remove a license key
- Open Settings > Keyguard Premium.
- Select Link existing entitlement token.
- Clear Entitlement token.
- Select OK. Keyguard removes the key from the vault.
Removing a key doesn’t cancel a subscription or refund a purchase. Manage a subscription in the store where you bought it.
License status
Keyguard shows the status of a key next to it in Settings > Keyguard Premium.
| Status | Meaning |
|---|---|
| Active | Premium is unlocked. |
| Grace period | Premium stays unlocked while the store resolves a billing issue. |
| Expired | The paid period ended. |
| Revoked | The purchase no longer grants premium. |
| Refunded | The purchase was refunded and no longer grants premium. |
| Pending | The purchase isn’t fully active yet. |
| Invalid | Keyguard couldn’t verify the key. |
Troubleshooting
”No eligible purchase found”
The Google account on this device didn’t buy premium. In Google Play, switch to the account that bought premium, then select Obtain entitlement token again.
”Could not obtain entitlement token”
Keyguard couldn’t verify the purchase. Check the internet connection, then try again.
”Invalid or expired key”
The key is incomplete or changed, or its purchase was refunded, revoked or expired. Copy the whole key again. For a Google Play purchase, select Obtain entitlement token on the device with the purchase.
Lost web purchase key
If you lost the key or closed the checkout tab before saving it, contact keyguard@artemchep.com with your Paddle receipt. Support can help recover your purchase.
