A page a day, for your eyes only. Write a few lines; Tekkoh keeps the rest of your day alongside, encrypted with a key only you hold.
Tekkoh is a journal for iPhone. Write a few lines each day, and Tekkoh quietly keeps the rest of the day beside them: where you went, how far you walked, the sky at sunrise and sunset, the photos you took.
And it keeps all of it to itself. Everything is encrypted on your phone, with a key only your devices hold, before it goes anywhere. Not even Tekkoh's server can read it.
A PAGE THAT FILLS ITSELF IN
• The places your day took you, named and in order
• Steps, distance and workouts from Apple Health
• Sunrise and sunset
• The day's photos, suggested so you can add them with a caption in a tap
Every permission is optional.
A NOTEBOOK, NOT A FEED
• One page a day, on cream grid paper
• A streak, kept with a brush-drawn ensō
• A month and year index of every page you've written
• Home screen and Lock Screen widgets
• On iPhone Duo, opens flat like a real notebook, with a focus mode for writing
PRIVATE BY DESIGN
• End-to-end encrypted: words, photos, places and activity
• Your key syncs through iCloud Keychain
• A six-digit PIN brings your journal back on a new phone
• No ads, no analytics, no tracking
• Delete your journal everywhere, any time
ON A COMPUTER, AND FOR YOUR AGENTS
Link a browser to read and write on a computer. Personal AI agents can link too, with your approval on your phone, and leave a short note in the margin about what they did for you that day.
