Privacy policy

In effect from 13 November 2026

Ravenline is a mail program that runs on your own computer or phone. This policy says what it does with your mail and your accounts. In short: your mail stays between you and your mail providers. Ravenline has no server of its own, and its makers never receive any of your data.

What Ravenline handles

• The letters in the mail accounts you add, with their attachments, folders and marks (read, starred, answered).
• The addresses of the people you write to and hear from, taken from those letters, to suggest them when you write.
• Your account settings, and what lets the app sign in: a password you give it, or the sign-in your provider (Google, Yandex) grants it.

Where it is kept

All of it is kept on your device only. Passwords and sign-ins are kept in your system's keychain or in the app's encrypted store. Nothing is sent to Ravenline's makers or to anyone else: there is no account with Ravenline, no analytics, no advertising and no tracking.

A backup is a file the app writes where you tell it to, a folder or a disk you choose, and it holds your mail. It goes nowhere else.

Who the app talks to

• The mail servers of the accounts you add (over IMAP, POP3 and SMTP), to bring your mail and to send yours.
• Google's and Yandex's sign-in services, when you sign in with them, and again from time to time to keep that sign-in valid.
• The servers a letter's pictures and fonts come from, when you open a letter that loads them from the internet, as in any mail program. Whoever sent the letter may learn from that that it was opened. The app can keep copies of such pictures on your device.

Your mail providers' data

This holds for every mail provider alike: Google (Gmail), Yandex, Mail.ru and any other whose mailbox you add. Ravenline reaches a mailbox in one of two ways:

• with a sign-in the provider grants it when you choose "Sign in with Google" or "Sign in with Yandex": access to your Gmail (https://mail.google.com/), or to your Yandex Mail (mail:imap_full and mail:smtp);
• with a password you give it, for most providers an app password you make for it.

Either way the app can read, send, move and delete your mail, and it uses that only to do what you ask of it in the app: to show your mail on your device, to send the letters you write, and to change and delete letters as you do. The data stays on your device; it is not sold, not passed on to anyone, not used for advertising, not read by any person, and not used to train any AI or machine learning model.

For Google in particular: Ravenline's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Your control

• Removing an account from Ravenline removes its mail and its sign-in from your device. Your mail on your provider's servers is not touched.
• Everything the app keeps is in its own folder on your device: removing that folder (on a phone, removing the app) removes it all, but for the backups you made.
• You can take back Ravenline's access at any time with your provider: for Google at myaccount.google.com/permissions, for Yandex in your Yandex ID's settings at id.yandex.ru, and for any provider by deleting the app password you made for Ravenline, or changing your password.

Children

Ravenline is not meant for children under 13.
