RainyDay Support
RainyDay is a private, local-first savings-jar app. It does not connect to a bank or store your amounts on a House Rhymaun server.
Contact
Email mmrhymaun@icloud.com. Include your iOS version, RainyDay version, and what happened. Do not send a backup that contains notes you want to keep private unless you are comfortable sharing it.
Restore Pro
Open Settings and tap Restore Purchases while signed in to the Apple Account that bought RainyDay Pro.
Backup
Pro can export a JSON file. Import is free so you can always get a backup back onto the phone.
