Account & Data Deletion

This page explains how to delete the data created by our apps — Nibble (com.lifecraftlab.nibble), Lái Chuẩn (com.lifecraftlab.laichuan) and Sayly (com.lifecraftlab.sayly) — and, if applicable, the account associated with the Google Sign-In option. The steps below apply to whichever app you use; substitute its name where we say “the app”.

Summary

• Most data is local.Your on-device data (e.g. Nibble's diary & profile, Sayly's learning progress) lives only on your device.
• Uninstalling the app removes that local data.
• If you signed in with Google, follow the steps below to also delete your account record on our side.

Option A — Delete local data only (no account)

If you have never signed in with Google, all your data is on your device. To delete it:

1. Open Android Settings → Apps → the app → Storage.
2. Tap Clear data (and optionally Clear cache) — this removes your local data for that app.
3. Optionally, uninstall the app to remove everything.

Option B — Delete your account & all associated data

If you signed in with Google, you can request deletion of your account and any server-side records linked to your Google email.

Self-service in the app

1. Open the app.
2. Go to Profile / Settings → Account (in Sayly, tap your account avatar in the top bar).
3. Tap Delete account. Confirm. Your account record and any associated server-side data will be permanently deleted within 30 days.

By email

If you cannot reach the in-app option, email us:

• To: contact@lifecraftlab.cc
• Subject:Account deletion request — include app name (Nibble / Lái Chuẩn / Sayly)
• Body: the Google email used to sign in, and a brief confirmation that you want your account and data deleted.

We will verify the request, delete your data within 30 days and email you a confirmation. We may retain limited records solely as required by applicable law (e.g., financial or fraud-prevention records).

What is deleted vs. retained

When you request account deletion:

• Deleted: Google email, display name, photo URL associated with your account; any server-side preferences or sync records.
• Already not stored on our servers: your on-device content (Nibble diary/profile, Sayly learning progress, etc.) — those live on your device only.
• Retained briefly: minimal backup data may persist for up to 30 days in standard backups before being purged, and limited records may be retained where required by law.

Third-party data

Photos sent to the Gemini AI service are not stored by us. Their retention is governed by Google's Privacy Policy.

Advertising identifiers used by Google AdMob are controlled by you in Android Settings → Google → Ads, where you can reset the ID or opt out of personalised ads.
