Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.simplesystemtrading.com/faqs/sst-website-faqs/privacy-faq.md). # Privacy FAQ Check out the [privacy policy](https://policies.simplesystemtrading.com/privacy-policy) for more detail as well. ### Is my email communication private? Yes for 100%. Your communication will not be shared with anyone else. There is no NDA needed for that. Email correspondence is going through [protonmail](https://www.protonmail.com) which is one of the most secure email providers based in Switzerland. All possible security practices are in place to prevent any email leakage. So yes your communication with SST is private. ### Can we work with an NDA? Yes. If you feel better that I sign a Non Disclosure Agreement (NDA) when discussing your proprietary trading secrets, that is totally fine with me. For public domain knowledge and information an NDA is not needed. ### What user data is stored on the SST backend? The SST website is very lightweight and very little user data is stored. Check the [privacy policy](https://policies.simplesystemtrading.com/privacy-policy) on what user data is stored. ### What user data is shared? No user data is shared, ever. ### How is user data stored? Emails and attachments are stored on the protonmail servers. Downloaded files from email are stored in [Sync](https://www.sync.com/?_sync_refer=94001c0) folders (Sync is secure storage software I use.[ Affiliate link here](https://www.sync.com/?_sync_refer=94001c0)) which are encrypted. The hardware I use has OS level encryption as well. Any backend infrastructure is secured with current cyber security practices. Passwords are strong and 2FA is used on everything. Your data, although minimally present, is well taken care of. --- # Agent Instructions This documentation is published with GitBook.
