Express Mobile sued Dropbox along with eight other technology companies over website-builder patents in 2020; the suit against Dropbox was resolved by dismissal, consistent with a settlement, rather than a court ruling on the merits.

Dropbox's OAuth model historically let third-party apps request full account access, and tokens persist until revoked — so a single over-permissioned or compromised integration can read, write or delete a user's entire Dropbox without any further prompt.

The EU's 2020 Schrems II ruling struck down the Privacy Shield framework over US surveillance, leaving EU organizations that store data with US providers like Dropbox needing extra safeguards — and unable to fully escape US legal reach.

Users complain that the Dropbox desktop app sets itself to launch at startup, embeds itself in Windows File Explorer and macOS Finder, and is difficult to fully remove — with 'failed to uninstall' errors and leftover launch agents, caches, and folders that must be cleaned out by hand.

Apple's App Store privacy 'nutrition labels,' introduced in December 2020, require apps to disclose their data collection — and the Dropbox app's label lists a broad range of data linked to the user's identity, from contact info and identifiers to usage data and diagnostics.

Long-running, widely reported complaints describe the Dropbox desktop client consuming excessive CPU, disk, memory, and battery — sometimes pinning processors above 100% and draining laptop batteries even when nothing is actively syncing.

Dropbox's 'Drop-ins' — the Chooser and Saver widgets that let any app use Dropbox as an open/save dialog — launched in 2013 with fanfare, but the iOS and Android Choosers were later deprecated and the program stagnated as Dropbox steered its platform away from third-party developers toward its own collaboration features.

Anyone viewing a publicly shared Dropbox Paper document could see the full names and email addresses of every signed-in Dropbox user who had ever opened it — turning a collaboration feature into a personal-data harvesting tool.

Dropbox Transfer lets users send files via a link, but its meaningful size limits are gated by tier: free Basic and entry plans are capped at 2 GB per transfer, with the headline 100 GB (and 250 GB with a Replay add-on) reserved for higher-priced business tiers.

Patent-assertion entity SynKloud Technologies sued Dropbox in the Western District of Texas over patents on wireless-device access to remote storage; Dropbox's bid to move the case to California was denied, while SynKloud's broader patent campaign unraveled at the patent office.
