Meet Semaphor SpiderOakONE Backup


Zero Knowledge

Our systems have Zero Knowledge of your data. In non-technical terms it means that your data is 100% private and only readable by you. No plaintext data, no keys, or file meta data is ever stored on our servers. All this ensures absolute confidentiality of your data.

Something to Protect

Privacy online seems to get a bad rap. We're told, "the only people who care about privacy are those who have something to hide." Well, we emphatically disagree. The notion we should not care about privacy is largely promoted by companies who depend on you being their product. It's not about what people want to hide, it's really about being able to choose that something is worth protecting.
