Your privacy is important to us. Psono follows some fundamental principles:
- We do not ask for any information that we do not really need
- We do not share your information with anyone except to comply with the German law, protect our rights and develop our product.
- No sensitive data like your passwords will ever leave your computer without being encrypted before
Any data (name, address, billing information, IP-address, …) is only used to fulfill the service and without a legal basis or your explicit consent, not given to any third parties.
Psono collects personal-identifying information like for example the IP address while using our service, to ensure the service availability and to protect your account. Psono may use that information for statistical analysis and may display this anonymized statistical analysis publicly or provide it to others.
Account holders in addition must specify some additional information during registration, like for example their e-mail address. That information is used to prevent service disruptions and to inform users about security relevant information.
For technical reason (login, sessions, ...) we are using browser storage (e.g. cookies, local storage, ...), which stores data in your browser.
This website offers the use of YubiKey OTP for multi-factor authentication. When using this feature the server will send your OTP token to the Yubico Validation Service to authenticate your token.
This website also offers the use of Duo for multi-factor authentication. When using this feature the server will register a user with your username with duo at the beginning. Later when you use Duo (e.g. during the login process), the server will send requests to the Duo service to identify you with them and protect your account.

This website uses Freshdesk to handle support requests. Whenever you are opening a new ticket, via email or support form it will be processes by Freshdesk including all information that you may provide in the process (IP, email address, all data of your support request, ...).
This website uses Sentry (from sentry.io) to handle errors. Whenever an error is recorded it's sent to sentry so problems can be fixed quickly. This is necessary to ensure the integrity, reliability and availability of the service for all users as testing cannot check all potential OS / browser / devices / version combinations.

The default configured HKP server is keyserver.ubuntu.com but can be changed in the settings.
