Privacy

This policy covers Mailglade 0.1.0 for Thunderbird, the add-on published on addons.thunderbird.net, and this website.

The short version

The add-on makes no network requests. It reads the folders you choose, builds a search index in Thunderbird's own storage on your computer, and answers your searches from it. Your messages, your queries and your results stay on that computer. There is no account, no sign-in, no payment and no server to talk to.

What the add-on stores, and where

Everything below is held in the storage Thunderbird gives the add-on, inside your Thunderbird profile on your own computer. None of it is transmitted.

• The search index: the text of messages in the folders you chose, including headers, message bodies and the text of attachments it can read, such as PDFs.
• Your settings: which folders each index covers, which index searches use by default, and whether indexing is paused.
• Saved filters and recent searches, if you save them. You can delete either at any time.
• An event log of counts and times, for the Diagnosis page. It records how many messages were read and how long a pass took. It holds no subject, address, message text or search text.

Removing indexed data in settings deletes the index, the saved searches and the log. Your mail in Thunderbird is not touched by anything the add-on does; it reads your mail and never writes to it.

What the add-on does not do

• It requests no host permissions, so it cannot contact a website, including this one. There is no telemetry, no crash reporting, no update check and no advertising identifier.
• It does not read folders you did not choose, and excluding a folder removes the copy it had already indexed.
• It skips encrypted messages rather than storing their decrypted text.
• It asks for no payment details and offers nothing to buy.

Thunderbird itself still talks to your mail provider the way you set it up. Indexing a folder can make Thunderbird download message bodies it had not fetched yet, from that provider, exactly as opening those messages would.

Permissions, and why each one is needed

• Read your email and see your mail accounts and folders: to read the folders you choose into the index, and to list folders so you can choose them.
• Store unlimited client-side data: the index is large, and a mailbox of tens of thousands of messages exceeds the default allowance.
• Schedule alarms: Thunderbird unloads the add-on when it is idle, and an alarm is how indexing picks up where it left off.

This website

mailglade.app uses no cookies, no analytics and no third-party scripts, and serves its fonts from this site. It is hosted on Cloudflare, which processes requests, including IP addresses, to serve pages and protect the service. The site sets no identifier of its own and builds no profile of you.

If you write to us

Mail sent to an address at mailglade.app is forwarded through Cloudflare Email Routing to a personal mailbox, and is kept only as long as answering you needs. It is not added to a mailing list or shared.

Children

Mailglade is not directed at children and collects nothing from anyone.

Changes

A later version that adds a feature reaching the network will say so here and in its add-on listing before you install it, and will ask before anything leaves your computer.
