Tane

Tane (種, "seed"; from tanemaki 種まき, "to sow seeds") is a local-first, decentralized app for

keeping and sharing traditional seeds.

Every traditional seed is a letter written by thousands of generations, passed

from hand to hand. Tane helps people and seed-saver collectives keep a

friendly inventory of their bank, decide what they offer, and share it locally

— without a central intermediary that could control, censor, or be fined for

it.

MANAGE YOUR BANK

• Add a seed with just a photo and a name — no Latin required.

• Note the year, how much you have, where it came from, germination tests.

• Search and filter; snap a photo now and name it later.

YOURS, AND ONLY YOURS

• Your seed book works with no internet at all. What you write stays on your

phone; nothing goes out unless you put some of your seeds up for sharing, or

write to someone.

• Everything is encrypted at rest on your device.

• No account, no sign-up, no ads, no trackers.

• Save an encrypted backup and keep a printed recovery sheet — restore your

whole bank on a new device.

SHARE, THE WAY IT'S ALWAYS BEEN DONE

• Mark what you have spare to give away, swap or sell.

• Print a catalog of what you share to take to a seed fair.

SHARING NEEDS THE INTERNET

Keeping your seed book needs nothing but your phone. Sharing does need a

connection: to get an offer or a message across to someone, Tane leaves it on
