PlanSync is built by one person, so the reply you get is from the person who wrote the code. Nothing here is a ticket queue.

The alarm does not ring or vibrate
Open Settings → Notifications and check that notifications are on. For the full-screen alarm, iOS 26 asks for a separate permission the first time a timer is armed — if you declined it, grant it in the iPhone Settings app under PlanSync. A ringtone set to None is silent on purpose, but it still vibrates.
Restoring a purchase
Subscriptions follow your Apple Account. Open Settings → Subscription → Manage subscription on the device signed in to the Apple Account that paid. If it still does not show, write to me with the receipt and I will sort it out.
Sync between devices
Two-way sync is a Pro feature. Sign in with the same account on every device, and give the first sync a moment on a slow connection. Without Pro the app keeps everything on the device, which is also why it works with no signal at all.
Getting your data out, or deleting it
The Chrome extension exports a full backup file you can keep. To erase a lost device remotely, use Sign out everywhere in the account menu. If you want your account and its cloud copy deleted, email me and it is done as soon as I read it.
Reporting a bug
Open Settings → Diagnostics and tap Send report — it attaches the last errors with your task titles stripped out. A sentence about what you were doing when it broke helps more than anything else.
