Privacy Policy

1 · In one line

WaChat stores your WhatsApp chats in your own Google Drive (the hidden app folder). Your messages and media never pass through our servers and we cannot read them.

2 · What is stored, and where

Data	Where	Who can read it
Messages, media, reactions	Your device + the hidden app folder in your Google Drive	Only you (through the app, or WaChat Plus Web with your account)
WhatsApp 64-digit encryption key	Your device only, wrapped with Android Keystore	Only the app on your device — never uploaded
Google account name, email, photo	Firebase Authentication	To sign you in and link your devices
Subscription state (Plus/free, plan, expiry)	Firestore entitlements/{uid}	You (read) — written by our server after verifying with Google Play
Google Play purchase token (SHA-256 hashed)	Firestore	Our server only — to link the subscription to your account
Share codes you create	Firestore	Whoever has the code and password
Crash and usage data (anonymised)	Firebase Crashlytics / Analytics	To improve the app — no messages or names

3 · Subscription (WaChat Plus)

• Payment is handled entirely by Google Play. We never see your card details.
• We receive the purchase token and its state (active / cancelled / refunded) from Google so we can turn Plus on for your account. That is all we store.
• When a subscription ends nothing is deleted. Only the extras switch off.
• Cancellations and refunds follow Google Play's policies.

4 · Permissions

• Drive (appdata): the hidden app folder only — not your files.
• Media / folder access (SAF): to read WhatsApp's local backup and media on your device.
• Contacts (optional): to show names instead of numbers, on your device only.
• Notifications: backup progress, today's memory, trial-ending reminder.

5 · Analytics

We log generic events (e.g. "subscription screen opened", "purchase succeeded — yearly plan"). They never contain messages, names or numbers.

6 · Deletion

• Deleting a chat in the app removes it from your device and, if you choose, from Drive.
• Deleting your account: Settings → Account, or contact us. We delete your entitlement document and share codes within 30 days. Your Drive data is yours and under your control in Google Drive → Settings → Manage apps.

7 · Children

The app is not directed at children under 13.

8 · Changes

We will notify you in the app of any material change.
