Delete my data

Last updated: 2026-04-20

Short version: Chronosync Plus never uploads your data to a server. Everything lives encrypted on your phone. You delete it by wiping it from the device — there's no separate account to close.

Option 1 — In-app reset (recommended)

Open Chronosync Plus on your phone.
Tap the Settings icon.
Scroll to Reset all data.
Confirm. Every on-device record is removed immediately, including your encrypted store, auth verifier, session history, vitamin-D logs, and app-block list.

Option 2 — Uninstall

Long-press the Chronosync Plus icon on your launcher.
Tap App info → Uninstall, or drag to Uninstall.
Android removes the entire Chronosync Plus app directory, including the encrypted store and all cached data.

Because Android auto-backup is disabled for Chronosync Plus, no silent copy of your data is retained in Google Drive after uninstall.

Option 3 — Email us

There is nothing on a server to delete — we don't have a server. But if you'd like written confirmation, or if you have questions about how a particular piece of data was handled, email support@chronosyncplus.com and we'll respond within 30 days.

What happens to your data when you delete it?

Encrypted Zustand store — erased from app storage.
Auth record (salt + verifier) — erased. Even if someone had your old storage file, without the password it was unreadable; after deletion it doesn't exist at all.
Session encryption key — was already only ever in RAM; cleared on logout / app-close.
Scheduled alarms — cancelled.
Focus-mode blocklist — removed.

What about data we sent to third parties?

The only outbound traffic from the app is anonymous API lookups (weather, reverse-geocode, timezone). Those calls carry latitude and longitude but no account identifiers, so there is no Chronosync Plus-specific record for those providers to delete. Their own privacy policies govern the logs they keep:
