The bottom line

Dropbox's AI features send your documents to OpenAI's servers, where they sit for up to 30 days. The AI settings are buried in account preferences and contradict each other across different pages. Amazon CTO Werner Vogels publicly warned people to check their Dropbox AI settings. When a Big Tech CTO tells you to check the settings on a competitor's product, something has gone wrong. Dropbox encrypts your files — but keeps the encryption keys. They comply with government requests about 75% of the time. Compare that to Proton Drive or Tresorit, where the company literally cannot read your files because they don't hold the keys. Dropbox's encryption protects your files from hackers. It does not protect your files from Dropbox.

⚡ highpolicy claims vs regulatory findings
In 2014, Dropbox appointed Condoleezza Rice — the former Secretary of State who supported warrantless NSA wiretapping — to its board of directors. 40,000 people signed a petition demanding her removal. Dropbox kept her. The file storage company that holds your documents chose a board member whose signature achievement in technology policy was helping the government read people's files without a warrant.

What they claim: Dropbox leadership is committed to privacy.

What we found: Board member Condoleezza Rice: former NSA warrantless wiretapping advocate. 'Drop Dropbox' campaign (2014). Surveillance supporter overseeing file storage.
