Intervalpad keeps your medicines and logs only in this browser on this device — nothing is uploaded, no account. Closing a private window or clearing browser data erases them, and they don't move to another device by themselves: save a backup file regularly.
Doses counted from the last one taken
Every 2 days, every 8 hours — counted from the last dose you actually took, not from a calendar. Late or logged afterwards, the next due moves with it.
Intervalpad is a log that counts your own interval from your last dose. It is not a medical device: it knows nothing about any medicine or dose and gives no advice — follow your prescription and your doctor or pharmacist. Reminders only sound while this page is open, so use your phone's Clock app for a dose that must not be missed.
