Description by CastleKeyp Corporation Written by the developer, not by AppBrain. Click to read.
At every stage of life, CastleKeyp helps you organize and manage the business of life. Organize your important personal information, keep up relationships, and lighten the mental load. Store your sensitive personal information and access it from anywhere.
End-to-end encryption protects your information for total privacy and security. Your information is just between you and the people you choose. Not even CastleKeyp can see it.

Your CastleKeyp Profile:
Home address, birthdates, allergies, family information and more - personal information you wouldn’t normally put online is entirely private and secure in your end-to-end encrypted CastleKeyp Profile. Only you and the people you choose to connect with on CastleKeyp can see it. Control what others see – share all or just parts of your Profile.

Your Profile is free to create and share with as many CastleKeyp Contacts as you choose. Great for remembering birthdays, sending gifts and much more!

Your end-to-end encrypted Keyp:
Welcome to your very own online Keyp: a single, accessible place to store and organize all of your personal information, end-to-end encrypted. As secure as a password safe, it's a template for organizing your home life - store home utility account information, family blood types, frequent flier accounts - every bit of personal information, so you never lose track again. Have your partner or trusted family member join CastleKeyp and you can permission them to see your Keyp - manage life together. Otherwise, it's for your eyes only.

Securely store information you need to manage the business of life. It will be there when you need it. One place, good for life.

Connect better:
Keep track of extended family and friends, with a fraction of the headache. Every CastleKeyp member updates their own Profile – so it's good information, right from the source - and no more trying to keep track of moves, contact information changes, children’s names, ages, allergies. Manage just your own CastleKeyp Profile instead of all of your contacts' cards. Have the useful information you need to reach the people who matter most in your life, for life. From a high school graduation to a wedding to a funeral and everything in between, reach your people when it matters most.

Joining CastleKeyp is free, private and secure - invite your friends, family and community. You can connect with unlimited CastleKeyp members.

Organize your social life:
We all have different social circles – Book Club, Wine Club, PTA, Fantasy Football, Little League, volunteer organizations. Create Custom Groups to keep in touch more easily. Send emails, text or export contact information with a single tap. Use CastleKeyp's Holiday Cards Group, and export your addresses for the printer with a single tap.

Or share sensitive personal information with a Partner or family member with CastleKeyp’s Pre-Set groups – clothing sizes for you and your family; SSNs and more with a Partner or family.

Never miss an important date again:
When does your passport expire? Put it into CastleKeyp, and you'll get a helpful reminder. All of your important dates populate automatically on the in-app Calendar. Birthdays and anniversaries for your CastleKeyp Contacts, expiration and due dates for your passport and more, all in one place. Get custom in-app and push notifications to stay on top of it all.

Save time, money and hassle with reminders for expiration and due dates for passports, credit cards, property tax bills, insurance policies and more.

Keyp your life in order - and spread the word! At every stage of life, CastleKeyp helps you organize and manage the business of life. All in one place.
