Privacy Policy

Last updated: 3 November 2026

Eekou was called Quakou until version 0.33. Only the name has changed: this policy, and what the program does with your information, are the same.

Eekou is an email program that runs on your own computer. This policy explains what Eekou does with your information. In short: your mail stays on your computer, it never passes through any Eekou server, and nobody at Eekou can read your mail.

What Eekou keeps, and where

• Your mail (messages, attachments, folders) is downloaded from your mail provider straight to your computer and kept there, in Eekou's data folder, in an encrypted store.
• Your accounts and settings are kept in the same place. Passwords, app passwords and sign-in tokens are stored encrypted, protected by a key kept on your computer.
• Notes, tags, rules, templates and contacts you create in Eekou are kept on your computer only.

Eekou does not send any of this to Eekou or to anyone else. There is no Eekou account and no Eekou cloud, and no Eekou server receives your mail, contacts, calendars, passwords or sign-in tokens.

Who Eekou connects to

• Your mail providers (for example Google, Microsoft, Yahoo or your own company's mail server), directly, to download and send your mail.
• Google, Microsoft and Yahoo sign-in pages, when you choose to sign in with them. You sign in on their own pages; Eekou never sees your password.
• Microsoft Graph (graph.microsoft.com), for Outlook.com and Microsoft 365 accounts that sign in with Microsoft, directly from your computer: to show your inbox as Focused and Other the way Microsoft sorts it, and to keep Outlook's categories and Eekou's tags alike.
• A mailing list's own unsubscribe page, only when you choose Unsubscribe for that list: where the list offers one-click unsubscribing, Eekou sends that page the single request the list asks for (List-Unsubscribe=One-Click) and nothing else; otherwise the page opens in your web browser, or Eekou writes the message the list asks for, for you to send.
• A proxy server, only if you set one (or choose the one Windows uses) in Settings: Eekou's connections then go through it, as your other programs' do.
• eekou.com, to check whether a new version of Eekou is available. This check sends nothing about you, your accounts or your mail.
• Pictures in messages are downloaded from the internet only if you allow it (for one message, for a sender you choose, or always, as set in Settings).
• Senders' pictures, only if you switch on "Look up senders' pictures online": Eekou asks Gravatar using a scrambled form (a hash) of the sender's address, never the address itself, and looks up the logo a company publishes for its mail domain. Answers are kept on your computer.

Google user data

When you add a Gmail or Google Workspace account with "Sign in with Google", Eekou asks for access to your Gmail (https://mail.google.com/) and for your email address. Eekou uses this access only to show you your mail, to send the mail you write, and to carry out what you ask (for example moving, flagging or deleting messages, or clearing out mail you choose in Clean-Up) in your own mailbox.

• Your Gmail data is kept only on your computer and is not transferred to Eekou or to any third party.
• It is not used for advertising, not sold, and not used to build profiles of you.
• No person reads your Gmail data. It is not used to train any artificial intelligence or machine-learning model.

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

Microsoft accounts

When you add an Outlook.com, Hotmail or Microsoft 365 account with "Sign in with Microsoft", Eekou asks for permission to read and send your mail through IMAP and SMTP, for your basic profile (name and email address), and, through Microsoft Graph, for permission to read and update your mail (Mail.ReadWrite: to show how Microsoft sorts your inbox into Focused and Other, and to keep categories alike) and your mailbox settings (MailboxSettings.ReadWrite: to keep your choice when you move all mail from a sender to Focused or Other, as Outlook does). As with Google, this access is used only for what you see and choose in Eekou, from your computer; nothing is sent to Eekou.

Yahoo and AOL accounts

When you add a Yahoo Mail or AOL Mail account with "Sign in with Yahoo", Eekou asks Yahoo for permission to read and send your mail through IMAP and SMTP, and for your basic profile (name and email address). You can also add these accounts with an app password you create in your Yahoo or AOL account settings; it is kept encrypted on your computer like any other password.

• Eekou connects from your computer directly to Yahoo's mail servers. Your Yahoo and AOL mail, and any contacts or calendars you choose to show in Eekou, are kept only on your computer and are never transferred to Eekou or to any third party.
• Your mail is processed only on your computer and only for features you can see and use: showing, searching and sorting your messages, checking whether a message really comes from its sender, showing meeting invitations, and carrying out what you ask in your own mailbox (for example moving, flagging or deleting messages). Eekou does not scan or extract your data for any other purpose.
• Your Yahoo and AOL data is not used for advertising or to build profiles or targeting segments, is not sold or otherwise monetised, and is not used to train any artificial intelligence or machine-learning model. No person reads it.

Removing your data

• Removing an account in Eekou (Settings, Accounts) deletes its mail, settings and sign-in from your computer.
• Uninstalling Eekou removes the program. You can also delete Eekou's data folder to remove everything it kept.
• You can withdraw Eekou's access at any time in your Google account (myaccount.google.com, Security, Third-party apps), your Microsoft account (account.microsoft.com, Privacy, Apps and services) or your Yahoo or AOL account (Account Security, Recent activity or Connected apps).

Children

Eekou is not directed at children under 13 and does not knowingly collect information from them.

Changes to this policy

If this policy changes, the new version will be published on this page with a new date.
