Kabelpost
Privacy
Your mail stays between you, your PC and your mail provider. Kabelpost has no account with us, no analytics and no tracking, and it never sends anything to its developer.
Kabelpost is in development. This statement describes how it is built to work, and it will be brought up to date before every release.
Who we are
Kabelpost is made by nagel.se in Sweden. Questions about this statement or your data: kabelpost@nagel.se.
What we collect
Nothing. Kabelpost has no telemetry, no crash reporting that phones home, no advertising and no user accounts. We cannot see who uses it, how, or what is in anyone's mail.
What stays on your computer
- Your mail. Kabelpost keeps a copy of your messages in a database in your Windows profile, so that it works offline and search is fast. You choose whether it keeps everything or only recent months.
- Passwords and sign-in tokens are kept in Windows Credential Manager, protected by your Windows account - never in Kabelpost's own files.
- Settings, such as which addresses appear in the taskbar panel, are kept in a file in your Windows profile.
- The AI. Kabelpost's AI features use a language model that runs on your own PC. Your mail is never sent to an AI service, ours or anyone else's.
Who Kabelpost talks to
Kabelpost connects only to these, always over an encrypted connection:
- Your mail providers' servers, to fetch, organise and send your mail. What they do with it is covered by their own privacy policies.
- Microsoft, when you use a Microsoft account (Outlook.com, Hotmail, Microsoft 365). Sign-in goes through Windows itself; Kabelpost receives a token for your mailbox and never sees your password. You can withdraw Kabelpost's access at any time at microsoft.com/consent.
- The AI model download, only when you choose to download a model. Like any download, the server it comes from sees your IP address.
- Automatic setup, only while you add an account, and only if a provider is not already known to Kabelpost: it may look up your mail domain's own setup information and Mozilla Thunderbird's public database of mail providers (autoconfig.thunderbird.net). Only the domain name is sent - the part after the @ - never your address or password.
- An outgoing mail relay, only if you set one up yourself for a forwarded address.
Pictures in emails that are loaded from the internet are blocked until you allow them, because loading them tells the sender that you opened the message. Links open in your own web browser.
Connecting other AI apps (MCP)
Kabelpost can let AI apps on your PC, such as Claude Desktop, read your mail through the Model Context Protocol. This is off until you turn it on, and you choose which addresses they can see and whether they may organise or send mail. Once you connect such an app, what it does with your mail - including sending it to its own online service - is governed by that app's terms and privacy policy, not ours.
Microsoft Store
If you install Kabelpost from the Microsoft Store, Microsoft handles the download and updates under its own privacy statement.
Removing your data
Uninstalling Kabelpost removes the app. To remove everything it kept, also delete the folders %LOCALAPPDATA%\Kabelpost and %APPDATA%\Kabelpost, remove the "Kabelpost" entries in Windows Credential Manager, and withdraw Microsoft access at microsoft.com/consent. Your mail itself stays with your mail provider.
Your rights
Because we hold no personal data about you, there is nothing for us to show, correct or delete. If you think otherwise, or have any question, write to kabelpost@nagel.se. You can also complain to the Swedish Authority for Privacy Protection (IMY).
Changes
If Kabelpost's handling of data changes, this page changes first, with a new date at the top.
