Where is my data stored?
On your device, and only on your device. ReefVitals has no accounts, no cloud, and
makes no network requests other than App Store purchase handling.
How are dosing amounts calculated?
Dry-compound doses use standard reef chemistry (the same stoichiometry as the
calculators the hobby already trusts). Liquid products use the potency printed on
your product's label. Doses that would raise a parameter too fast are automatically
split across days. Always retest before dosing again.
What does Pro include?
The corrective dose calculator, water change planner, unlimited tanks, and full
history. Manage or cancel anytime in Settings → Apple Account → Subscriptions.
How do I restore a purchase on a new phone?
Open any Pro screen and tap "Restore Purchases."
