Privacy Policy — Numolo

Last updated: 22 August 2026

The short version

Numolo has no servers. Nothing you type is transmitted anywhere. Everything the extension saves stays in your own browser, on your own device.

What the extension stores

All of it locally, using the browser’s chrome.storage.local API:

Data	Why
Saved contacts — the name and phone number you enter	So you don’t retype numbers you message often
Templates — message text you save	So you don’t retype messages you send often
Recent recipients — the last 8 numbers you messaged	One-click reuse. Can be turned off, and cleared at any time.
Your current draft — the phone number and message in the compose box	A browser popup is destroyed the moment it loses focus; without this, half-typed messages would be lost
Preferences — theme, whether recents are recorded	To remember your settings

What the extension does not do

• No servers. The developer operates no backend. There is nothing to send data to.
• No accounts, no sign-in.
• No analytics, telemetry, tracking, or advertising.
• No selling or sharing of data, to anyone, for any purpose.
• No reading of web pages. The extension holds no host permissions and injects no scripts. It cannot see the pages you browse.
• No access to your device’s contacts. Contacts saved here are separate from your phone’s address book and are never written to it.
• No message sending. The extension opens WhatsApp Web with a prefilled message. You send it yourself, in WhatsApp.

Permissions

The extension requests one permission:

• storage — to save the data listed above in your browser. This permission does not grant access to anything else.

Opening a new tab requires no permission in Chrome, which is why nothing else is requested.

Where your data goes when you send

When you press Send, the extension opens a WhatsApp URL in a new tab of your own browser:

https://web.whatsapp.com/send?phone=<number>&text=<your message>

At that point the number and message are handled by WhatsApp, under WhatsApp’s own privacy policy. The extension is not involved in the delivery of the message and has no visibility into your conversations.

Your control over your data

• Delete any saved contact or template from the Library at any time.
• Clear your recent-recipients list, or turn the feature off entirely.
• Uninstalling the extension removes everything it stored.

Because the data lives only on your device, the developer cannot access, recover, or delete it on your behalf — and equally, cannot lose it or hand it to anyone.

Children

The extension is not directed at children and collects no information about anyone.

Changes

If a future version stores or transmits anything differently, this policy will be updated in the same release that introduces the change.
