Seal by Kyoto Makotoya

Seal is the companion app for Grain Patch, a bandage-shaped leather patch designed to carry what matters.

Choose what you want to keep close, write it to your Grain Patch, and access it anytime with a simple tap.

WHAT YOU CAN SEAL

• Contact — Share your name, phone number, email, and company details with a single tap

• Message — Leave a personal note, reminder, motto, or private message

• Website — Save a website, portfolio, or social profile

• Location — Store a map link or GPS location for quick access

• Erase — Clear your Grain Patch and start fresh at any time

SECURITY BY DESIGN

All data is encrypted with AES-256-GCM before leaving your device. Encryption keys are generated locally and are never sent to a server. Only someone with physical access to your Grain Patch can read what you've saved.

DESIGNED FOR GRAIN PATCH

Seal is purpose-built for Kyoto Makotoya's Grain Patch. The app guides you through each step, from choosing what matters to writing it securely to your patch.
