Mailsheet ("the extension," "the service," "we," "us") is a Google Chrome extension that reads your Gmail inbox, uses artificial intelligence to classify each message (for example: order, invoice, lead, complaint, or shipping), and writes the extracted details into a Google Sheet that you own. This policy explains exactly what data the service accesses, how it is processed, and what we do and do not do with it.
To do its job, the extension requests permission to access the following:
Gmail messages (read-only). The extension uses the gmail.readonly permission to read the content of your email messages — including subject lines, sender, body text, and PDF attachments — so each message can be classified and its details (such as order numbers, amounts, and customer names) extracted. The extension cannot send, delete, or modify any of your emails. It only reads them.
Google Sheets. The extension uses the Google Sheets permission to create and write to a spreadsheet in your own Google account. This is where the organized output is stored. The extension only accesses the spreadsheet it creates or that you connect for this purpose.
Your email address. The extension reads your Google account's email address. We use it solely to identify your account for usage limits and, if you upgrade, to link your subscription to your account.
Local storage on your device. The extension stores configuration locally in your browser (your settings, your spreadsheet identifier, and a local troubleshooting log). This data stays on your device.
When you run a scan, the following happens:
Important: We do not retain, log, or store the content of your email messages on our servers. Email content passes through our processing service only momentarily to be classified, and is not saved. The only data we keep about you is your account email address and a count of processed emails (and, if you subscribe, your payment status).
If you upgrade to Mailsheet Pro, payments are processed by Stripe. We do not see or store your full card details — Stripe handles that securely. We receive only confirmation that your subscription is active, linked to your account email.
The service relies on the following third parties to function. Each has its own privacy policy:
Mailsheet's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We only use Google user data to provide and improve the extension's classification and organization features, and we do not transfer or use it for advertising, or for any purpose other than what is described in this policy.
You can stop Mailsheet at any time by removing the extension from Chrome. You can revoke its access to your Google account at any time in your Google account permissions. The Google Sheet belongs to you and remains yours.
