Privacy Policy — Quietly

Last updated: June 8, 2026

Quietly (“the Extension”) is a Chrome extension that scans your Gmail inbox for trial ending notices, price increase emails, and subscription renewal warnings, and surfaces them in a private side panel. This policy explains exactly what data the Extension reads, what it stores, and what it never does.

1. Summary

Quietly processes your email data exclusively inside your browser. No email content, personal information, or usage data is ever sent to any server, shared with any third party, or stored anywhere other than your own device.

2. What data the Extension accesses

When you are on mail.google.com, the Extension reads the following from your Gmail inbox through the browser’s DOM (the visible page content):

Email subject lines
Sender names and email addresses
Email body text, only where it is already rendered on screen

This reading happens locally, inside your browser, in order to detect keywords associated with trial endings, price changes, and subscription renewals.

The Extension does not use the Gmail API and does not request OAuth access to your Google account.

3. What data is stored

Detected alerts and associated metadata (sender domain, renewal date, urgency level, and whether you have seen the alert) are saved to chrome.storage.local — browser-local storage that is:

Stored only on your device
Never synced to Google’s servers or any other server
Never accessible to any website or third party
Cleared if you uninstall the Extension or use the Extension’s built-in clear function

The Extension also stores aggregate statistics (e.g., number of emails scanned) in chrome.storage.local for display in the side panel. This data never leaves your device.

4. What data is never collected

The Extension does not collect, transmit, or store:

The full content of any email
Your Google account credentials or identity
Browsing history outside of mail.google.com
Any personally identifiable information
Crash reports, analytics, or telemetry of any kind

We share no data with anyone. The Extension makes no network requests to external servers. There are no analytics services, advertising networks, or third-party SDKs included.

6. Permissions used and why

Permission	Why it is needed
`storage`	Saves detected alerts and vendor data locally on your device
`sidePanel`	Displays your alerts in Chrome’s side panel
`host_permissions: mail.google.com`	Allows the content script to read the Gmail page in order to detect relevant emails

No other permissions are requested.

7. Data retention and deletion

All data stored by the Extension remains on your device for as long as the Extension is installed. You can delete all stored data at any time using the clear function inside the Extension, or by uninstalling the Extension. Uninstalling removes all chrome.storage.local data associated with Quietly.

8. Children’s privacy

The Extension is not directed at children under the age of 13 and does not knowingly process data from children.

9. Changes to this policy

If we make material changes to this policy, we will update the “Last updated” date at the top of this page. Continued use of the Extension after any changes constitutes acceptance of the updated policy.
