Seasons and Sensei letters.
Phases end. In Kata, a phase that ends becomes a kept chapter, and rare letters mark the moments that are truly earned.
Seasons
When a phase ends (a cut, a build, a hold, a peak), Kata closes it into a season: a chapter with its honest numbers frozen at close time. The trend delta and weekly rate (under the same honesty guards as everywhere else), protein adherence, session volume, your strongest week, the range you held. Only real chapters are kept: a same-day phase switch or an untouched span leaves no trace.
Your seasons collect on a shelf in Profile. They live in your local store, so backup, snapshots and export carry them automatically.
Sensei letters
Rarely, when something is truly earned, a letter arrives: a strong season close, a long-held weight goal reached, thirty or a hundred clean days on a quit-style tracker, a sixty-day streak of practice, or about three months of steady showing up. It is written for you, in your language, in the sensei's voice.
Rarity is the point
- Never two letters within 45 days, at most five a year, none before 30 active days.
- Coinciding milestones are absorbed into one letter, not stacked.
- A letter is never faked: if it cannot be written well, it waits.
Sharing a letter
A letter stays private unless you share it, and each one offers three ways: Print or save as PDF, Share as image (made on your device) and Share a public card. The public card is exactly what its preview shows: your archetype mark, a few counts and one line, never your name, the letter text or a health value. It gets a link you can share or copy. Remove the public link takes it down at once, deleting the card and its image, and a removed card's link stays dead for good.
Letters are stored on your device like everything else and ride your backups. Our servers only ever learn that a letter happened, never what it says, and hold a public card only while you keep it up.
