We offer Free Email Account with limited features
We believe privacy is a fundamental human right, so we provide free accounts as a public service. You can still support us by telling your friends and family about Mail-Cubic.com.
*Mail-Cubic.com cannot be used for sending spam/unsolicited emails or for bulk emailing
The Company is domiciled in Estonia and all data storage infrastructure is also located solely within Estonia, and thus governed by the laws and regulations of Estonia.
Any emails provided to Mail-Cubic.com through either our waiting list, optional email verification, or optional notification/recovery email setting in your account, are considered personal data as defined and protection by the Estonian Federal Data Protection Act.
Such data will only be used to contact you with important notifications about Mail-Cubic.com, to send you information related to security, to send you an invitation link to create your Mail-Cubic.com account, to verify your Mail-Cubic.com account, or to send you password recovery links if you enable the option. We may also inform you about new Mail-Cubic.com products in which you might have an interest. You are free, at any given time, to opt-out of those features through the account settings panel.
In order to maintain the integrity of the service, Mail-Cubic.com must take measures to avoid creation of accounts by spammers. This is because if spammers use Mail-Cubic.com to send messages, Mail-Cubic.com’s IP addresses can become blocked by major mail providers such as Gmail, Yahoo, Outlook, etc.
In order to prevent the creation of accounts by spam bots or human spammers, Mail-Cubic.com uses a variety of human verification methods. You may be asked to verify using either reCaptcha, Email, or SMS. IP addresses, email addresses, and phone numbers provided are saved temporarily in order to send you a verification code and to determine if you are a spammer. If this data is saved permanently, it is always saved as a cryptographic hash, which ensures that the raw values cannot be deciphered by us.
Our company’s overriding policy is to collect as little user information as possible to ensure a completely private and anonymous user experience when using the Service. We also have no technical means to access your encrypted message contents.
Service's user data collection is limited to the following:
We do not have any advertising on our site. Any data that we do have will never be shared except under the circumstances described below in the Data Disclosure Section. We do NOT do any analysis on the limited data we do possess with two exceptions:
All servers used in connection with the provisioning of the Service are located in Estonia and wholly owned and operated by the Company. Only employees of the Company have physical or other access to the servers. Data is ALWAYS stored in encrypted format on our servers. Offline backups may be stored periodically, but these are also encrypted. We do not possess the ability to access any user encrypted message content on either the production servers or in the backups.
Through the Service, you can directly access, edit, delete or export personal data processed by the Company in your use of the Service.
If your account has been suspended for a breach of our terms and conditions, and you would like to exercise the rights related to your personal data, you can make a request to our support.
When a Mail-Cubic.com account is closed, data is immediately deleted from production servers. Active accounts will have data retained indefinitely. Deleted emails are also permanently deleted from production servers. Deleted data may be retained in our backups for up to 14 days.
We will only disclose the limited user data we possess if we receive notice from the Estonian Public Prosecutor's office or the Estonian Federal Police regarding a court. While we may comply with electronically delivered notices (see exceptions below), the disclosed data can only be used in court after we have received an original copy of the court order by registered post or in person and provide a formal response.
If a request is made for encrypted message content that Mail-Cubic.com does not possess the ability to decrypt, the fully encrypted message content may be turned over. If permitted by law, Mail-Cubic.com will always contact a user first before any data disclosure. Under Estonian law, it is obligatory to notify the target of a data request, although such notification may come from the authorities and not from the Company.
Mail-Cubic.com may from time to time, contest court orders if there is a public interest in doing so. In such situations, the Company will not comply with the court order until all legal or other remedies have been exhausted. Therefore, not all court orders described in our Transparency Report will lead to data disclosure.
This Agreement shall be governed in all respects by the substantive laws of Estonia. Any controversy, claim, or dispute arising out of or relating to the Agreement shall be subject to the jurisdiction of the competent courts of Estonia.
