Your Personal Relational Database

Release Status: 3.6.1 | Docs

Simple. Flexible. Relational.

Kase exists because it should. There should be a database app that can go anywhere with you. It should be:

  • Simple — so using it should be easy and intuitive,
  • Flexible — so once familiar with the basics, you can design any database to track anything important to you, and
  • Relational — because you don't want to repeat yourself, and inter-linked data becomes an order of magnitude more useful.

Additionally, it should be:

  • Personal — because you should not need to worry about who can peek into your data, and
  • Always Available — because high-speed wireless network connection should not be a prerequisite for accessing your own data.

Something like that didn't exist, so I started creating Kase in 2014.

Kase is all that. It is not perfect, but it does its job well.

Kase's Side Menu, with access to Boxes.

Basic Concepts

  • Your Kase contains Boxes.
  • Each Box stores Decks that can be related to each other.
  • A Deck collects similarly structured Cards.
  • And a Card is where you put data Entries.


  • Box can be locked with a passcode, and unlocked with Face ID or Touch ID.
  • Deck definitions support inheritance!
  • Pick and organize Decks and Cards with categories, tags, and bookmarks.
  • Highlight any box, deck, card, entry, or keyword.
  • Write in Markdown and see rich formatted text.
  • Use Formatters (Fx), Units to visualize data in different ways without altering the data one bit.
  • Full text indexing with NLP.
  • Side-by-Side: Compare Cards easily by displaying in columns.
  • Complete backup and restore.
  • iPad Multitasking support: Split View, Slide Over, etc.

From Data to Wisdom


Data ▹ Information ▹ Knowledge ▹ Wisdom

What Kase Does

  1. Store Data: the objective truths
  2. Organize Information: reflects circumstances/current condition
  3. Systematically retrive Knowledge: usable/utilized for decision making
  4. And that hopefully enables you to grasp Wisdom, comprehend insights, and ultimately create value.

What Kase is Not

  • Cloud syncing yet (stay tuned...)

"Unbig" the Data

There are some databases that belong to the Big Guys. The rest of them should stay personal.

By now you should realize how valuable your data is. So why give it away? Kase keeps your data yours.
