Free trial
2-day app preview
Every new install comes with a 2-day free preview. No subscription or payment is required. The preview starts the first time the app connects to the internet after install and cannot be extended by reinstalling - the timer is tied to the device via a stable identifier.
When the preview expires, a paywall is shown and the app requires an active subscription to continue.
14-day subscription trial
The Monthly and Yearly plans each include a 14-day free trial. Billing only begins after the trial ends. You can cancel before the trial ends without being charged. The 14-day trial is only available the first time you subscribe; it does not apply to renewals or plan switches.
Managing your subscription
Subscription management is handled through the platform store. In-app options are available in Settings → Subscription.
| Action | How |
|---|---|
| Purchase | Use the plan picker in the app (paywall or Settings → Subscription) |
| Restore purchases | Settings → Subscription → Restore Purchases - use this after reinstalling or switching devices |
| Cancel | Settings → Subscription → Cancel Subscription - opens the App Store or Google Play subscription management page |
| Upgrade to Yearly | Settings → Subscription → Upgrade Plan - shown when on a Monthly plan |
| Upgrade to Lifetime | Settings → Subscription → Upgrade Plan - shown when on a Yearly plan |
Cancelling stops renewal at the end of the current billing period. Access remains active until the period ends.
Grandfathered access
Users who downloaded SharKNX before the subscription model was introduced retain lifetime access at no charge. The Settings → Subscription page shows this as SharKNX Ultimate (Legacy). No action is required.
Offline behaviour
If the app cannot reach the subscription server and no valid cached state exists, it shows an Unable to Verify status. The app does not lock you out in this state - connect to the internet and tap Restore Purchases to re-verify your subscription.
