No. Scailer is a desktop application that encrypts all sensitive data and stores it on your computer.

Scailer uses an encrypted connection to your mail server via IMAP or SMTP. It also connects to our services to check for version updates and contact information discovery, which uses your contact's email address to search the internet for publically-available information about them (e.g. social profiles).

Scailer will automatically update to a new version every quarter, and we will also release other updates as new features are created.

The database where email messages, addresses and passwords are stored on your computer has two-level encryption (without performance degradation) and is protected from computer viruses. Even if someone were to make a copy of your database, it could not be read by any other program or by another Scailer instance.

All credentials are encrypted, so no one can extract them without authorization.

Scailer uses several proprietary algorithms that make it different from competitors.

Yes.

The app sends IMAP and SMTP commands to your mail server via a secure connection with credentials you provide. It also sends email addresses of your contacts to our own remote search engine, which uses a secure connection to search the internet for publically-available information about your contacts. You can disable contact information discovery if you wish, without affecting the app’s other functions.

We remotely store only publically-available data about your contacts that has been found using our contact information discovery feature. Encrypted messages and passwords are stored on your computer.

Because your messages are encrypted and stored only on your computer, no third-party servers are involved. You may opt in to helping us improve Scailer by selecting "Automatically send error reports" in the settings. These error reports are stored on our servers, and may contain fragments of a message if related to the error that occurred.

Important email messages (security notifications, password reset requests, trial expirations, etc.) are displayed in your Contacts mailbox.

Not in the human "reading" sense. Scailer parses messages to transform them into a readable form, but it does not understand the message's content. Scailer has an embedded advertisement detector, but it also does not understand your messages like a human.

No. We want you to concentrate on your important emails – without distraction. Our app contains no advertisements. In addition, advertising emails from external sources are sorted into the Robots box.

We believe you do not need rules with Scailer, but if you prefer rules, you can add them via your email provider's interface. IMAP does not support rules, so Scailer cannot synchronize them. If you want to use several email clients or Scailer instances from different places, we recommend setting up rules directly in your mail provider's interface.

Because Scailer automatically categorizes your messages by contacts, we think you won’t need IMAP folders. If you still want them, however, they’re available via the advanced search window.

All emails related to a contact or group, including sent mail, are displayed by default. You can still see just sent mail by choosing the "sent" folder in the left panel.

Scailer has a Contacts folder that includes all messages from your main contacts. There also is a Promo and Robots folder where you can see all periodic and marketing messages, if you'd like.

By default, Scailer sorts contacts by activity level, so the most active contacts are listed at the top. Contacts you may only use once per year are still there, and you can either search for them or scroll down.

Yes. You can merge multiple email accounts into a single Scailer instance.

Unfortunately, POP3 is outdated and lacks several important features, so it was not a smart option when we considered encryption and overall security. Scailer supports only IMAP v4rev1 and compatible protocols.

Yes. Messages are sent via secure SMTP connection.

While many modern mail providers obtain excellent results in spam processing, Scailer is more aggressive, and will provide better security for users. That’s especially important as spammers become more sophisticated and phishing schemes become more prevalent. Scailer automatically detects advertising messages and hides them under the Promo and Robots tab, and it completely hides images in phishing messages.
