History

Proton Drive's development began in 2019, supported by a grant from the European Union's Horizon 2020 research and innovation program. A beta version of the Proton Drive service was launched to paid Proton subscribers on November 16, 2020, and opened to non-paid users in June 2021. In October 2021, the Proton Drive web app underwent an independent security audit by Securitum. During August and September 2022, Proton Drive Android and iOS apps were also independently audited by Securitum. The service exited beta and launched publicly via web app on September 22, 2022, followed by the release of iOS and Android apps on December 7, 2022. The source code for the Android and iOS apps was open-sourced on March 2, 2023, along with the publication of the security audits. On 16 May 2023, Proton Drive launched a version control feature that allows users to restore older versions of their files, and launched a Windows app on July 12, 2023. A desktop app for macOS was released on November 23, 2023. A photo backup feature for Android was added on December 7, 2023. On February 20, 2024, Proton Drive increased the storage limits for its free plan from 1GB to 5GB. On July 3rd, 2024, Proton released Docs in Proton Drive, an end-to-end encrypted, real-time collaborative, document editor feature. In August, the company launched Proton Drive for Business offering real-time cloud collaboration for teams.

Reception

Proton Drive received mixed reviews upon launch. Reviewers noted the low storage limits and lack of features but also noted the high level of security. Cloudwards commented, "the size of a free account (up to 1GB) combined with basic sharing and no collaboration make Proton Drive feel light on features. What you trade in productivity, however, you more than make up for in security and privacy". PCMag remarked, "If security and privacy are your main concern in a cloud storage app, Proton Drive is the best choice. But that peace of mind comes at a price." Subsequent releases and feature updates improved its reception. Following the release of the macOS desktop app, Boy Genius Report wrote, "Proton Drive is the app that might make me finally switch over from Google." Android Police noted, "Proton Drive is finally becoming a viable alternative to Google Drive" after the Windows app launch. In February 2024, PCMag rated Proton Drive the best cloud storage provider for privacy and security. Proton Drive is one of only three cloud storage providers recommended by Privacy Guides.
