Mejl App Privacy Policy

Last updated: July 9, 2026

1. Overview

Mejl is a macOS email client developed by Oskar Wilhelmsson. Mejl is designed to run locally on your Mac. This App Privacy Policy explains what information the app accesses, how it is used, and what stays on your device.

This policy covers the Mejl macOS app. For the mejl.ai website, cookies, and website analytics, see the Website Privacy Policy.

2. Data Handled on Your Device

Mejl is designed to keep your data on your device. The app may access and store:

  • Email content and metadata. When you connect Gmail or Outlook, Mejl downloads and stores your email on your Mac so it can display and search your mailbox.
  • Drafts and messages you create. Messages and drafts you write in Mejl are stored locally on your Mac. If you save a draft to a connected Gmail or Microsoft account, that draft may also be stored by that provider. When you send an email, it is transmitted through your connected mail provider and delivered to the recipient's mail server.
  • Account credentials. For Microsoft accounts, Mejl stores OAuth access and refresh tokens issued by Microsoft. For Gmail accounts, Mejl stores the Google app password you provide for IMAP/SMTP access. These credentials are stored on your Mac in macOS Keychain. Mejl never requests or stores your normal email account password.
  • Local indexes and AI data. Search indexes, embeddings, and local model selections are stored on your device so Mejl can provide local search and local drafting features.
  • Speech input. If you use dictation, Mejl uses macOS speech recognition features to convert your speech into text for the draft or AI prompt field. Mejl does not store audio recordings or send them to Mejl-operated servers. Speech recognition may be handled by Apple/macOS according to your system settings and Apple's privacy terms.

Mejl does not collect analytics, telemetry, or crash reporting on Mejl-operated servers.

3. How Mejl Uses Your Data

The app uses this information only to provide its features:

  • Displaying your inbox and email threads.
  • Saving drafts and sending messages you create.
  • Enabling local full-text and semantic search across your emails.
  • Running local AI-assisted drafting on your Mac.
  • Converting speech input into text when you choose to use dictation.

4. Third-Party Services

Mejl integrates with the following third-party services:

  • Google (Gmail / Google Workspace). When you connect a Google account, Mejl uses Gmail IMAP/SMTP with a Google app password to read, sync, save drafts, and send mail. Your use of Google services is subject to Google's Privacy Policy.
  • Microsoft (Outlook / Microsoft 365). When you connect a Microsoft account, Mejl uses Microsoft's OAuth 2.0 flow and the Microsoft Graph API to read, sync, save drafts, and send mail. Your use of Microsoft services is subject to Microsoft's Privacy Statement.
  • No external AI APIs. Mejl uses local, on-device AI inference only. Email content is not sent to OpenAI, ChatGPT, or any other external AI API by the app.

Mejl communicates only with the mail providers you explicitly connect so it can sync and send email for your account.

5. Data Retention and Deletion

Mejl does not store Google user data or Microsoft user data on Mejl-operated servers.

If you connect Gmail or Outlook, Mejl stores a local cache of mailbox data on your Mac so the app can function as an email client. That locally stored data is retained on your device until you remove it.

You can remove locally stored mailbox data by:

  • disconnecting the account and choosing Delete Local Data in the app;
  • deleting Mejl and its associated local app data from your Mac; or
  • otherwise removing the app's local data from your device.

OAuth access and refresh tokens, and Gmail app passwords where applicable, are stored separately in macOS Keychain. Disconnecting an account removes Mejl's local Keychain copy. For Gmail app passwords, you can also revoke the app password in your Google Account.

Deleting local data from Mejl removes Mejl's local copy from your Mac. It does not automatically delete emails, synced drafts, sent mail, labels, or other data that remain stored in your Google or Microsoft account. Data that remains with Google or Microsoft is subject to their own retention and deletion policies.

6. Data Storage and Security

Mejl stores email data, settings, indexes, OAuth tokens, and Gmail app passwords where applicable on your Mac, inside the app's local storage, macOS Keychain, and security-scoped sandbox locations where applicable. Mejl does not operate a cloud backend for your mailbox data.

If you delete Mejl or its associated data from your Mac, the locally stored app data is removed from that device.

7. Children's Privacy

Mejl is not intended for children under the age of 13. If you believe a child has used Mejl in a way that resulted in personal information being stored through the app, please contact us at info@mejl.ai so the matter can be addressed.

8. Changes to This Policy

This App Privacy Policy may be updated from time to time. Changes will be posted at mejl.ai/app-privacy with an updated "Last updated" date. Continued use of Mejl after changes constitutes acceptance of the revised policy.
