| Your seed bank in your pocket |
Keep and share traditional seeds and seedlings — offline, encrypted, no account. |
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 it, censor it, or be fined for it.

Manage your bank |
Add a seed or seedling with just a photo and a name — no Latin required. Note the year, how much you have, where it came from, germination tests. Search, filter, snap now and name later. |

Share, as it's always been done |
Mark what you have spare to give away, swap or sell. Someone nearby finds it and contacts you — no middleman. Print a catalog of what you share to take to a seed fair. |

| Why Tane is different |
| No center: no company can shut it down, censor it, or be fined for it. |
| Anti-monopoly by design — sharing seeds multiplies the commons instead of depleting it. |
| Spreads like a seed, person to person, with no server in the middle. |
| Free software (AGPL-3.0). No ads, no commissions, no business model. |
