EML & MSG Viewer for Google Drive™, by Arkpine Software, does not collect, sell or share personal data. It has no server of its own: the site is static files, and everything the viewer does happens in your browser. A file you open from your computer is never uploaded anywhere.

Google user data

When you open a file from Google Drive with EML & MSG Viewer, the app asks Google for permission with the scope drive.file, and with drive.install, which adds the app to Drive's "Open with" menu. With these, the app can read only the files you open with it. It cannot list or read anything else in your Drive. It never changes your files; it creates new ones only when you click Save to Drive (Pro).

• What is accessed: the file you chose (its content, name, type and size).
• How it is used: the file is downloaded directly from Google's servers into your browser, so you can view it. The message is read in your browser, and its HTML is shown in a locked frame that cannot run scripts, load anything from the network or reach the rest of the page.
• Where it is kept: only in your browser's memory while it is open. Your choice between the HTML and plain text views stays in this browser's local storage; no message or part of one is kept. Nothing is sent to us or to anyone else.
• Access token: Google's short-lived access token stays in your browser tab's session storage and is discarded when the tab closes or after an hour.
• Sharing: Google user data is not transferred to anyone, not used for advertising, and not read by humans.

Pro Save to Drive, only when you click it: the app saves the message as a PDF and each attachment as a file in your Drive, in the folder of the email you opened when Drive allows it, otherwise in My Drive. For this it reads which folder the opened file is in, and the names of the files the app itself saved there before, so that a new file does not take the name of an earlier one. To make the PDF, it uploads the message (remote images still left out) to your Drive as a temporary Google Doc, has Google Drive export it as a PDF, and deletes the temporary Doc right after. The saved files are yours, in your Drive; the app does not read them again.

EML & MSG Viewer's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

You can remove the app's access at any time in your Google Account under Third-party apps and services. To delete what the viewer remembers on your device, clear this site's data in your browser.

Network requests

• Google: sign-in (accounts.google.com) and the Drive API (googleapis.com), only to open a file you chose and, if you use Pro Save to Drive, to create the PDF and the attachment files in your Drive.
• Pro purchases are processed by Lemon Squeezy (lemonsqueezy.com) on their checkout page. The app only sends the license key you paste to Lemon Squeezy's license API to check that it is valid, with a random instance name. See lemonsqueezy.com/privacy.

The app itself sets no cookies and contains no analytics or tracking scripts. Cloudflare, which hosts the site, keeps standard access logs (IP address, time, page), as any web server does, and we see the total number of visits to each page. The Get Pro button opens a short link on this site (app.arkpine.com/buy/eml-web) that forwards straight to the Lemon Squeezy checkout; so do the links of the team keys (app.arkpine.com/buy/eml-team-10, app.arkpine.com/buy/eml-team-50); we look only at how many times each link was opened, never at who opened it.
