Who receives it
We share personal data only with providers who help us run the business and process data on our behalf under a contract, such as hosting, email and IT providers, accounting firms and legal advisers. Public authorities receive data only where the law requires it. We do not sell personal data.
Transfers outside the EEA
Our email is provided by Proton AG in Switzerland, a country the European Commission recognises as providing an adequate level of data protection. If another provider processes personal data outside the European Economic Area, we rely on appropriate safeguards, such as the standard contractual clauses approved by the European Commission.
Your rights
You have the right to:
- access your data and receive a copy of it
- have inaccurate data corrected
- have data erased or its processing restricted
- receive the data you provided in a portable format
- object to processing based on our legitimate interests
- withdraw consent at any time, without affecting processing carried out before
To use these rights, write to crestcompact@proton.me. You can also lodge a complaint with the President of the Personal Data Protection Office (Prezes Urzędu Ochrony Danych Osobowych), ul. Stawki 2, 00-193 Warszawa.
Providing data is voluntary, but without contact details we cannot reply to your brief. We do not use automated decision-making or profiling.
