Masterymeaning, not capture

Mastery

Mastery: the upstairs door, never a toll.

KairSun Free is the full journal, forever: 4 pillars, free or focus sessions, notes, meals, companion, tree, achievements, streak, GP and export. Mastery adds the layer that interprets what you already log — one subscription. No “Super”. No “Max”.

Free vs Mastery, module by module

The same app, two levels of reading. Pick a module: Free logs and shows your raw data; Mastery crosses it, compares it and names patterns. Every card carries a concrete example and a before/after with sample data.

Depth, in six examples

This is what the difference looks like once there is enough history. The data is sample data; the evidence thresholds are real: if they are not met, Mastery would rather say nothing than invent.

  • Sample data
  • Real evidence thresholds
  • Below threshold, nothing shown
  • Water · Real week

    “Tuesdays average 96% of your goal; Sundays, 58%.”

    There is a single goal; what changes is your day. Reminders, on the other hand, are set per day, each with its own hours.
  • Mood · Typical week

    “Sundays your energy dips and ‘Work’ shows up next to it.”

    Shows up next to, never “causes”: the app makes no causal claims and does not diagnose.
  • Routine · Punctuality

    “87% of what has a schedule is marked within 30 minutes; Fridays drift to the night.”

    Same-day marks only: anything logged later does not inflate the number.
  • Limits · Slip and return

    “Your first slip came on day 9, Saturday is the hardest day and it takes you 2.5 days on average to get back to a clean day.”

    No slips, no average: what did not happen is not averaged.
  • Skills · XP distribution

    “90D and 1Y complete: the exact XP distribution per attribute, not just the total.”

    Below the evidence threshold, this reading is not shown: it is not padded with estimates.
  • Meals · 90 days

    “90 days of your meals, without the day-31 cut: which weeks hold and which fall off.”

    With no data, the day stays empty and grey: it is not backfilled with estimates.

What Mastery does NOT do

  • Export and delete always free
  • No data hostage
  • USD preview, no checkout
  • Nothing free becomes paid

Honesty

  • It does not hold your data hostage. Mastery sells the interpretation, never the reading: the day-by-day history stays open for 30 days on Free and complete with Mastery.
  • Export and delete stay free, today and later. The upstairs door does not lock the exit.
  • Nothing that is free today becomes paid. Free is the full journal, not a trial.
  • No checkout on this site. The app's store shows its USD preview and nothing is paid here; the purchase opens at launch.

Stage honesty: in-app purchases are off. Free plays in full; Mastery is offered as reading, not as a lock. The store shows its USD preview; there is no checkout here.

Economy is separate (not Mastery)

  • Seedscosmetics
  • Sunsprestige
  • GPdaily progress
  • Mastery≠ pack

Seeds are Rare/Epic cosmetics. Suns are earned prestige, never bought. GP is your daily local progress, with a cap. Mastery is the interpretation subscription. Mastery ≠ Seeds pack. Suns ≠ Mastery. The Legendary pet skin is not a Mastery pack: it is also sold in the Neon Sanctuary pack and is the pre-launch prize at 10 valid referrals, redemption to be confirmed.

Founders: redeem with the same email from the list to add 1 month of Mastery + 500 Seeds + Founder badge once redemption is active, pre-launch. The list alone does not redeem.

Frequently asked questions

Does Mastery lock my journal if I do not pay?

No. Free is the full journal forever: 4 pillars, free or focus sessions, notes, meals, companion, tree, achievements, streak, GP and export. Mastery only adds reading; it never removes access.

Are there prices or a checkout on this site?

No. In-app purchases are off: the app's store shows its USD preview and there is no checkout here. When the purchase opens, the official store names the price, never this page.

Does Mastery include Seeds, Suns or the Legendary skin?

Does Free lose anything when Mastery turns on?

No. Nothing that is free today becomes paid, and export and delete stay free today and later.
