Only on your phone (and your Apple Watch or Wear OS watch, if you use one). There is no account and nothing is sent to us. See the privacy policy for the details.

In the app, open Settings, Backup, and choose Back up to a file. Save it somewhere you can reach from the new phone, such as Files, AirDrop, Google Drive or an email to yourself, then choose Restore from a backup on the new phone and enter the same password. Restoring replaces everything on that phone.

Yes. A backup made on iPhone restores on Android, and one made on Android restores on iPhone, using the steps above. VialOwl Pro does not move with it: a subscription or Lifetime purchase stays with the App Store or Google Play, wherever you bought it.

We cannot recover it. The password is never stored or sent anywhere, which is what keeps the file private. Make a new backup from the phone that still has your records.

VialOwl only draws a curve when there is published human pharmacokinetic data for that compound. Where there is not, it says so rather than guessing.

No. Every amount is entered by you. The app shows what published research reports and what models predict, for education only.

On iPhone, open iOS Settings, tap your name, then Subscriptions, and choose VialOwl; Apple handles refunds. On Android, open the Play Store app, tap your profile picture, then Payments and subscriptions, Subscriptions, and choose VialOwl; Google handles refunds. Cancel at least 24 hours before the renewal date. VialOwl Pro Lifetime is a single payment, so there is nothing to cancel. If you buy Lifetime while subscribed, cancel the subscription yourself so it does not renew.

Open Settings in VialOwl and choose Restore purchases while signed in with the Apple Account or Google account you subscribed with or bought Lifetime with.

On iPhone, check that notifications are allowed for VialOwl in iOS Settings, Notifications, and that Focus modes are not silencing them. On Android, open Settings, Apps, VialOwl and check that notifications are on and that Alarms and reminders is allowed, so reminders arrive on time, and that Do Not Disturb is not silencing them.
