HarborKeep gives the important details of your life one private, organized home. More than a password manager, HarborKeep is designed for family records, emergency contacts, medical and insurance information, travel and legal documents, secure notes, login details, photos, files, drawings, and attachments. BE READY WHEN IT MATTERS Build an Emergency Dashboard so critical contacts, documents, and records are easy to find when every second matters. START QUICKLY, ORGANIZE YOUR WAY Use built-in Starting Points to shape common records, then customize categories and fields around the way you think. Track important dates, connect related records, and search, sort, or filter your library. KEEP THE WHOLE STORY TOGETHER Add notes, drawings, photos, documents, and other attachments to the record they belong with. Capture text or files from other apps using the iOS share sheet. Private on-device analysis can help identify useful details, tags, categories, and important dates. HarborKeep AutoFill can provide eligible login details when enabled in iOS Settings. PRIVATE BY DESIGN Your vault content is encrypted on your device. When iCloud is enabled for HarborKeep in Apple device settings, encrypted records can sync through CloudKit and the matching vault key can sync through iCloud Keychain to your trusted Apple devices. Decryption happens on your device after authentication. HarborKeep does not require a separate account or use a developer-operated vault server. It does not sell or profile your information for advertising. Passwords are supported, but HarborKeep is built for more: it is a private place for the records and details you may need today, while traveling, during an emergency, or when helping your family stay organized.
