Mailday

Privacy policy

Last updated 14 October 2026

Mailday is an email and calendar app for Mac, iPhone and iPad, made by Roberto Zanon (“we”). This policy explains what data Mailday uses, where it is kept and how you control it.

Mail and calendar on your devices

When you connect an email account, Mailday downloads your messages, attachments, folders or labels, and calendar events directly from your provider (such as Google or your IMAP server) to your device, and keeps them there so you can read and manage them. Passwords and sign-in tokens are kept in your device’s Keychain. Actions you take — such as reading, archiving, moving, deleting, labelling, sending or answering an invitation — are sent to your provider.

Google user data

With your permission, Mailday accesses your Gmail account (read, organise, send and delete messages) and your Google Calendar (view your calendars and create or change events). Mailday uses this data only to provide the app’s features to you: showing, searching, organising and sending your mail, and showing and managing your events. We do not use Google user data for advertising, we do not sell it, we do not use it to train AI or machine-learning models, and no person reads it unless you ask us to for support or it is required by law.

Mailday’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Mailday account and sync (optional)

If you sign in to a Mailday account (with a one-time code sent to your email address), Mailday keeps your connected accounts, their sign-in details and your settings on our server so they can be restored on your other devices. This information is encrypted on the server; it is server-side encryption, so our server can decrypt it to restore your accounts. The contents of your messages are not stored on our server.

To show new-mail notifications when the app is closed, our server checks your connected mailboxes for new messages and sends the sender’s name and address, the subject and the first lines of each new email to your devices through Apple’s Push Notification service. These details are not kept after the notification is sent.

Sender pictures

To show a company logo next to an email, Mailday may request the public website icon of the sender’s domain directly from that website. This request includes your IP address, as any web request does, but no content of your mail.
