We respect your privacy


In the following policy, O2-Mail.com refers to the service offered by Innotech OU (the "Company" or "We") through the O2-Mail.com website (the "Service"). This Privacy Policy explains (i) what information we collect through your access and use of our Service (ii) the use we make of such information; and (iii) the security level we provide for protecting such information.

By visiting O2-Mail.com and using the Services provided here, you consent to the terms outlined in this privacy policy.

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 O2-Mail.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 O2-Mail.com, to send you information related to security, to send you an invitation link to create your O2-Mail.com account, to verify your O2-Mail.com account, or to send you password recovery links if you enable the option. We may also inform you about new O2-Mail.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, O2-Mail.com must take measures to avoid creation of accounts by spammers. This is because if spammers use O2-Mail.com to send messages, O2-Mail.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, O2-Mail.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:

  • Account creation: It is not necessary to provide personal information in order to create an account, but you may provide an external email address for notification or password recovery purposes. Should you choose to provide it, we do associate another email address with your account (for password recovery, or notifications).
  • Account activity: Due to limitations of the SMTP protocol, we have access to the following email metadata: sender and recipient email addresses, the IP address incoming messages originated from, message subject, and message sent and received times. We do NOT have access to encrypted message content but unencrypted messages sent from external providers to O2-Mail.com are scanned for Spam and Viruses for the protection of our users. We also have access to the following records of account activity: number of messages sent, amount of storage space used, total number of messages, last login time.
  • Communicating with O2-Mail.com: Your communications with the Company, such as support requests, bug reports, or feature requests may be saved by our staff.
  • IP Logging: By default, O2-Mail.com does not keep permanent IP logs. We also don't record your login IP address unless this feature is specifically enabled by the user. However, IP logs are sometimes kept to combat abuse and fraud, and your IP address may be retained if you are engaged in activities that breach our terms and conditions (spamming, DDoS attacks against O2-Mail.com infrastructure, brute force attacks, etc).
  • Payment Information: The Company relies on third parties to process credit card, PayPal, and Bitcoin transactions so the Company necessarily must share payment information with third parties. Anonymous cash or Bitcoin payments and donations are accepted however.
  • Native Applications: When you use our native applications, we (or the mobile app platform providers) may collect certain information in addition to the information mentioned elsewhere in this Policy. We may use mobile analytics software (such as fabric.io app statistics and crash reporting, Play Store app statistics, App Store app statistics, or self-hosted Sentry crash reporting) to send crash information to our developers so that we can fix bugs rapidly. Some platforms (such as the Google Play Store or the Apple App Store) may also collect aggregate, anonymous statistics like which type of devices and operating systems that are most commonly used (like percentage of Android 6.x vs Android 7.x), the total number of installs, total number of uninstalls, and the total number of active users, and may be governed by the privacy policy and terms and conditions of the Google Play Store or the Apple App Store. None of the software on our apps will ever access or track any location-based information from your device at any time.

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:

  • Emails sent unencrypted to O2-Mail.com accounts (e.g. Gmail to O2-Mail.com) are scanned automatically for spam so we can block IPs which are sending a lot of spam to O2-Mail.com users and place spam messages in a spam directory. Inbound message are scanned for spam in memory, and then encrypted and written to disk. We do not possess the technical ability to scan messages after they have been encrypted.
  • Emails sent by O2-Mail.com users to outside (e.g. Gmail) users with encryption disabled are scanned automatically for spam in the same manner as incoming email. This is to ensure a O2-Mail.com account which is being used for spamming purposes can be detected and locked so email deliverability for legitimate users is not degraded.

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 O2-Mail.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 O2-Mail.com does not possess the ability to decrypt, the fully encrypted message content may be turned over. If permitted by law, O2-Mail.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.

O2-Mail.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.

O2-Mail.com reserves the right to periodically review and change this policy from time to time and we will notify users who have enabled the notification preference about changes to our Privacy Policy. Continued use of the Service will be deemed as acceptance of such changes.

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.
