In the case of Sentry, the data is anonymized before being sent to Sentry’s servers. Any piece of data resembling a path or a private key is removed on a best-effort basis. The data sent to Sentry is subject to a data processing agreement limiting Sentry’s use of the data and requiring Sentry to take appropriate security measures to protect the data.

Second, as described in more detail below, in certain cases we may process information where this is necessary to meet legal obligations, such as compliance with law enforcement subpoenas or warrants, and/or to further our legitimate interests, so long as any such legitimate interests are not overridden by your rights or interests.

Nomic Foundation does not sell your information. As set out below, we only share information on a limited basis in order to enable us to offer our services. We do not otherwise make Client data available to third parties.

When your data is moved from its home country to another country, the laws and rules that protect your personal information in the country to which your information is transferred may be different from those in the country where you reside.

However, no method of transmission or storage is 100% secure. As a result, while we strive to protect your personal information, you acknowledge that: (a) there are security and privacy limitations inherent to the Internet which are beyond our control; and (b) security, integrity, and privacy of any and all information and data exchanged between you and us through this Site cannot be guaranteed.
