Your data lives on your phone first.
KairSun is used without an account. What you log stays on the device; the cloud is optional: creating an account turns sync on for every module, and you can turn them off one by one. And the exit door —export and delete— is always open, free, and without login.

- Cloud opt-in
- JSON export without login
- Two-step deletion
Local-first
What lives on your phone
The phone is the source of truth while you use the app signed out. You can have a full day of Flow, care for your pet, and watch the tree grow without creating an account.
-
Water
The glasses you log, with your daily goal.
-
Mood
Your emotion and the free text you write in it.
-
Routines
Habits and their completion, day by day.
-
Skills
Practice sessions: duration, effort, and notes.
-
Pet
Care, ball, and your companion's state.
-
Progress
XP, streak, achievements, tree, and the game economy.
Your notes, meals, and photos also live here. Photos you attach to a note, a meal, or your profile are not uploaded to any server, not even for backup: if you uninstall the app or change phones, they don't travel.
Cloud opt-in
What only leaves if you say so
Nothing leaves the phone by default. This is what can travel, and always because you turn it on or send it.
-
Account and sync
Creating an account is optional and exists so your progress survives a phone change. Creating an account enables sync for every module; after that you can turn off the ones you don't want, and the rest stays only on the phone.
-
Referrals
The program does require a registered account: without one, a referral link can't be credited.
-
Reports and analytics
A report only leaves when you send it; the screenshots you attach are deleted after 90 days. Usage analytics is opt-in and aggregated.
-
Purchases
Payment is processed by Google Play. We never receive or store your card details.
The complete detail, provider by provider, is in the Privacy Policy (Spanish). We don't sell your data or publish your content.
Your data, your copies
Export everything as JSON, no login
Download my data
In Settings → Your data → Download my data the app builds a readable JSON file with all your tables —water, mood, routines, notes, meals, skills, achievements, preferences, and more— plus format metadata. It doesn't ask you to sign in because the data belongs to the device.
{
"format": "kairsun-export",
"format_version": 1,
"schema_version": …,
"exported_at": "2026-…",

}
}The only thing of yours left out is your profile photo: it's a JPEG on disk, not a row, and the file keeps its path, not the image. The internal sync queue is skipped so you don't see duplicate records. Export and delete are free, today and later.
Local vs cloud
The same app, two places
Move your view and see what happens to the data in each case. The cloud isn't hidden: creating an account turns everything on, and you can turn modules off one by one.
| What | On your phone | In the cloud · opt-in |
|---|---|---|
| Water, mood, routines, skills, and notes | Always: it's the source of truth | Creating an account syncs everything; you can turn modules off |
| Profile, meal, and note photos | Always | Never: not uploaded, not even for backup |
| Progress, achievements, and game economy | Always | If you enable an account, to recover them when you change phones |
| JSON export | Always, no login | Not needed: it comes from the device |
| Delete | From the app, in two steps | Immediate and irreversible; encrypted backups for up to 30 days |
Seeds and Suns are not money. KairSun is not a medical device.
Danger zone
Delete your account, in two steps
Delete account
It's a button that is always available: you don't need to write to us or explain anything. Deletion is immediate and irreversible and takes both the cloud data and the phone data.
- Open Settings → Account → Delete account.
- Read the warning and confirm by typing DELETE MY ACCOUNT. If you want to keep something, export first: there is no way back afterwards.
Encrypted backup copies may persist for up to 30 days and then delete themselves through rotation. See the deletion page.
Control stays on your side.
Local-first isn't a loose feature: it's how the app is built. If you want the complete legal detail, it's written and one click away.
