Yes. VANDR stores everything locally on your device. Uninstalling permanently deletes your data. If you're moving to a new phone, set up iCloud restore before deleting VANDR on the old one so your data carries over.

Unfortunately we cannot — your data lives only on your device. To prevent losing a streak in future, use the grace days (up to 3 per month) when a day slips, or enable Daily Workout Reminder in Profile → Notifications.

Open VANDR PRO from Profile or any locked PRO screen, scroll down and tap Restore Purchase. Make sure you're signed in to the App Store with the same Apple ID you originally bought PRO with.

If you miss a single day, you can use a grace day to keep your streak alive. Each calendar month gives you up to 3 grace days. The option appears on the Home screen the day after a missed day, only if your streak is at least 2 days long.

Yes — Profile → Notifications. You can pick from the preset times, or (PRO) set any custom time.

VANDR uses your weight × 35 ml when weight is logged. If you've only entered height, it estimates ideal body weight and uses that × 35 ml. If neither is set, it defaults to 2.5 L. You can override with a custom goal in the Hydration sheet.

Not yet. Export is on the roadmap. If you need it urgently, email us and we can advise.

VANDR doesn't use accounts. To erase everything: Profile → App → Reset All Data, or uninstall the app. Both fully delete your VANDR data from your device.
