Please read this Privacy Policy carefully. By starting to use our Services, you consent to this Privacy Policy.

We care about the protection and confidentiality of your data. We therefore only process your data to the extent that:

  • It is necessary to provide the Logos services you are requesting,
  • You have given your consent to the processing, or

Information we collect and process

We neither rent nor sell your information to anyone. Conversations are not shared with any other company or service. We will never sell your personal data or conversation history.

We DON’T knowingly collect or store medical information or Protected Health Information as any information about health status, provision of health care, or payment for health care that can be linked to a specific individual.

We collect information you intentionally provide through the Services.


In operating the Services, we may use a technology called “cookies.” A cookie is a piece of information that the computer that hosts our Services gives to your browser when you access the Services.

Our cookies help provide additional functionality to the Services and help us analyse Services usage more accurately. For instance, our Site may set a cookie on your browser that allows you to access the Services without needing to remember and then enter a password more than once during a visit to the Site.

We may also allow third party service providers to use cookies or similar technologies to collect information about your activities on our website or in our mobile apps following your use of the Services.

In all cases in which we use cookies, we will not collect Personal Data except with your permission. On most web browsers, you will find a “help” section on the toolbar. Please refer to this section for information on how to receive notification when you are receiving a new cookie and how to turn cookies off. We recommend that you leave cookies turned on because they allow you to take advantage of some of the Service features.

With whom we share your personal information

We may de-identify or anonymize your information so that you are not individually identified, and provide that information to our partners. We also may combine your de-identified information with that of other users to create aggregate de-identified data that may be disclosed to third parties who may use such information to understand how often and in what ways people use our services, so that they, too, can provide you with an optimal experience. For example, we may use information gathered to create a composite profile of all the users of the Services to understand community needs, to design appropriate features and activities. However, we never disclose aggregate information to a partner in a manner that would identify you personally, as an individual.

Hosting and Backend infrastructure

This type of service has the purpose of hosting data and files that enable our Services to run and be distributed as well as to provide a ready-made infrastructure to run specific features or parts of the Services.

How we secure and protect your information

We use a variety of industry-standard security technologies and procedures to help protect your data from unauthorized access, use, or disclosure.

All transmitted data are encrypted during transmission. We use standard Secure Socket Layer (SSL) encryption that encodes information for such transmissions. All stored data are maintained on secure servers. Access to stored data is protected by multi-layered security controls including firewalls, role-based access controls and passwords.

While we use reasonable commercial efforts to protect the data, no technology, data transmission or system can be guaranteed to be 100% secure. In the event of a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to your data, we will notify you as soon as we spot the issue.

Where we store your data

Our services are operated in the United Kingdom. We will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this Privacy Policy.

Data retention

We will only retain your personal information for as long as necessary to fulfill the purposes we collected it for, including for the purposes of satisfying any legal, accounting, or reporting requirements.

To determine the appropriate retention period for personal information, we consider the amount, nature, and sensitivity of the personal information, the potential risk of harm from unauthorized use or disclosure of your personal information, the purposes for which we process your personal information and whether we can achieve those purposes through other means, and the applicable legal requirements.
