Privacy Policy

Last updated: 19 October 2026

ChatAssistant (published on Google Play as “ChatAssistant - Business”) is an Android app that automatically answers the customers who write to your business on WhatsApp, following rules that you create. It works through WhatsApp Web, which the app opens inside itself as a linked device of your own WhatsApp account. This policy explains what information the app uses, where it is kept and how you can delete it.

1. Who is responsible

ChatAssistant is developed and published by Web Business Tools (blasmani), from Peru. You can write to us at webbusinesstoolspro@gmail.com.

Because the app keeps all of its data on your own phone, the developer has no access to it. You control that data and can delete it at any time, as explained in section 7.

2. Information processed on your phone

All of the following is processed and stored only on your device, in the app’s private storage:

• Incoming messages in one-to-one chats. When a new message arrives in an individual chat, the app reads its text and the sender’s name and number to compare it with your rules and decide whether to reply. It also reads the messages you send yourself, only to detect the exact phrases you set up as triggers. Messages from groups, status updates, broadcast lists and channels are ignored, and the app does not keep copies of your conversations.
• Your rules. Names, keywords, reply texts, active hours, delays, follow-ups and the other options of each rule.
• Media files. The photos, videos, audio files and PDFs you choose with the Android file picker are copied into the app’s private storage so they can be sent; audio can be converted into voice notes on the phone. The app does not browse your gallery or your files and does not ask for storage permission.
• Activity log. Date and time, the customer’s name and number, an excerpt of the received message (up to 60 characters), the rule applied and the result of each send.
• Statistics. Daily counts of messages received, replies, files sent and customers served, and how many times each rule replied. They contain no message content.
• Follow-up schedule. For the follow-up messages you set up: the chat, the customer’s name, the rule, the time the follow-up is due and whether it was sent or cancelled.
• Chat memory. Chat identifiers (phone numbers) with the date each chat was first seen, the last time each rule replied in it (for anti-spam pauses) and whether the customer asked not to receive automatic replies, for example by writing “baja” or “stop”.
• WhatsApp Web session. The keys and data of the linked session, kept in the storage of the app’s built-in browser (Android WebView), just as any browser keeps a WhatsApp Web session.
• Your connected account. The name, number and profile photo of your WhatsApp account, to show them on the home screen.
• Subscription status. Whether ChatAssistant Pro is active, its plan, whether it renews, the time of the last check and the purchase identifier (token) Google Play gives the app, used to recognize the plan you bought on this phone. It never includes your card or payment details.
• Settings. Your preferences, such as language, theme, test mode, active hours, daily reply limit and background options.
• Example content. The app comes with sample rules, texts, images, a video, a PDF and a voice note from a fictitious store, “Kusi Accesorios”, so you can try it right away. They contain no real person’s data. Replace them with your own information and files before you use the assistant with real customers.

3. What we do not do

• ChatAssistant has no servers. Nothing listed above is sent to the developer or to anyone on the developer’s behalf.
• No analytics, no advertising, no tracking tools and no profiling.
• No account or sign-up: you only link your own WhatsApp.
• We do not sell, rent or share data.
• The app does not ask for access to your location, camera, microphone, contact list, photos or files.

4. Internet connections

The app connects to the internet only for the following:

• WhatsApp Web. The built-in browser opens web.whatsapp.com and loads what WhatsApp Web needs from WhatsApp and Meta servers and content networks. It is your own WhatsApp Web session: the communication with WhatsApp is the same as in any browser, messages keep WhatsApp’s end-to-end encryption, and WhatsApp’s terms and privacy policy apply to it.
• Your profile photo. The app downloads your own account’s profile photo from WhatsApp’s servers to show it on the home screen.
• The web connector. To read new messages and send replies, the app uses an open-source connector (WPPConnect wa-js) that is included inside the app. The connector features that would send data to third parties, such as Google Analytics statistics and link previews through external servers, are turned off.
• Connector updates (jsDelivr). The app can only replace the included connector with a newer version that the developer has reviewed and approved inside an app update, identified by its SHA-256 fingerprint. In the current version of the app no newer version is approved, so the app does not contact jsDelivr or any other download server. If a future update approves one, the app will download that exact file from cdn.jsdelivr.net when it checks for connector updates (about once a week while “Update connector automatically” is on, or when you ask for it in Settings), and will discard it if the fingerprint does not match. That download sends no personal data; as with any download, the server can see your IP address and basic technical data. You can turn automatic connector updates off in Settings.
• Google Play Billing (ChatAssistant Pro). To show the plans and their prices, sell the subscription, restore it and check whether it is still active, the app talks to the Google Play app on your phone. Google processes the purchase and your payment method under the Google Play Terms of Service and Google’s privacy policy; the app never sees your payment details. For sales reports and refunds, Google shares with the developer the order information it gives every Google Play developer (such as order number, date, plan, price and country), never your card details.
• Google. Google distributes the app through Google Play, and the built-in browser is Android System WebView, provided by Google, which may check the addresses it opens with Google Safe Browsing. Depending on your device settings, Google may also receive crash reports. Google’s privacy policy applies to these services.
• Actions you start. If you share the app, export the activity log, open a help link or write to us by email, the app you choose is used and only what you decide to share is sent. We use the information in your email only to answer you.

5. Android permissions

• Internet and network state: to connect to WhatsApp Web and know whether there is a connection.
• Notifications: to show the service’s status and to alert you if the session disconnects or something needs your attention.
• Foreground service: to keep your WhatsApp Web session working in the background while the service is on, always with a visible notification from which you can stop it.
• Start at boot: to turn the service back on after the phone restarts or the app is updated, only if the service was on and the “Start when the phone turns on” option is enabled.
• Keep the processor awake: only while a reply is being sent, for a limited time.
• Battery optimization: to ask you, with your confirmation, that Android does not stop the service in the background.
• Google Play billing: to buy, restore and check the ChatAssistant Pro subscription through the Google Play app.
• Installed apps: the app only checks whether WhatsApp or WhatsApp Business is installed, to suggest the best way to link, and whether a text-to-speech engine is available, which can only be used to prepare the example voice note on the phone with a fixed demo text.

6. Security

The data is kept in the app’s private storage, protected by Android, which other apps cannot read. ChatAssistant excludes its data and the WhatsApp Web session from Android backups and from transfers to a new device, so the session is never copied off your phone. Exported log files are temporary: only the latest one is kept, files older than one day are removed automatically, and all of them are deleted when you clear the log or log out.

We recommend protecting your phone with a screen lock: anyone who can use your unlocked phone can open the app.

7. Retention and deletion

• Rules and files: kept until you delete them. Deleting a rule also deletes the files that no other rule uses.
• Activity log: at most the 2,000 most recent entries and nothing older than 30 days; older entries are deleted automatically. “Clear” in the Activity log deletes it at any time (statistics are kept).
• Follow-ups: follow-ups that were sent or cancelled are deleted automatically after 30 days.
• Anti-spam memory: the last time each rule replied in each chat is kept for one year at most.
• Statistics and chat memory: kept on your phone while you use the app, so that welcomes, opt-outs and your charts keep working.
• WhatsApp Web session: “Log out of WhatsApp Web” in Settings unlinks this device and deletes the session, the saved name and number of your account and any exported log files; your rules and files are kept. You can also unlink it from your main phone in WhatsApp > Linked devices.
• Everything: uninstall the app, or go to Android Settings > Apps > ChatAssistant > Storage > Clear data.
• ChatAssistant Pro: the subscription belongs to your Google account, not to the phone. Uninstalling the app or clearing its data does not cancel it: cancel it in Google Play > Payments & subscriptions > Subscriptions. Google keeps the purchase records under its own policies.

There are no copies anywhere else, so there is nothing we need to delete for you, and nothing we could recover for you either.

8. Your customers’ data

If you use ChatAssistant to serve your customers, you decide what is answered and you are responsible for processing their personal data in accordance with the law that applies to you; in Peru, Law No. 29733 on Personal Data Protection and its regulations. Reply only to people who write to you, and respect those who ask not to receive automatic messages.

9. Children

ChatAssistant is a tool for businesses, intended for people aged 18 or over. It is not directed to children, in particular to children under 14 (the age below which Peruvian law requires the consent of a parent or guardian) or under 13. We do not knowingly process children’s data. If a child has used the app, clearing its data or uninstalling it deletes everything it stored.

10. Changes to this policy

We may update this policy, for example when the app’s features change. The current version is always available in the app and at https://blasmani.github.io/chatassistant/privacy.html, with its update date. If a change is significant, we will also tell you in the app.

11. Not affiliated with WhatsApp

ChatAssistant is not affiliated with, endorsed or sponsored by WhatsApp LLC or Meta Platforms, Inc. WhatsApp is a trademark of WhatsApp LLC. The name is used only to describe what the app works with.
