Managing or cancelling your subscription: subscriptions are managed through your Apple ID or Google account, not inside iQuli. On iPhone/iPad, go to Settings → your name → Subscriptions. On Android, open the Play Store app → Payments & subscriptions.
Restoring a purchase on a new device: open iQuli, go to Settings, and use "Restore Purchases" — this re-links your existing subscription to your account.
Free trial questions: trial eligibility and length are shown on the plan you select before you confirm a purchase, and any unused portion of a trial is forfeited if you buy a subscription during it.
Deleting your account or data: you can delete your account at any time from within the app, or email us and we'll do it for you.
Bug reports and feedback: email us with your device model and iOS/Android version if something isn't working — screenshots help a lot.
