The short version

  • Only Arc has a free tier, so it costs nothing to try first.
  • Each has a real cost: Arc no longer receiving active feature development as of May 2025, entering maintenance mode; DataGrail no pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
  • They diverge on capability: Arc covers Spaces and Profiles, DataGrail covers Live data discovery.
  • Prices and features above were last checked on 31 August 2026.

  • Separating personal and professional browsing with spacesnot DataGrail
  • Privacy-conscious web browsing without trackingnot DataGrail
  • Tab and window management for productivitynot DataGrail

DataGrail

  • An organisation needing evidence for a regulator that deletion actually occurred in every system, not that a ticket was closednot Arc

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arc

  • No longer receiving active feature development as of May 2025, entering maintenance mode
  • Limited cross-platform availability compared to mainstream browsers
  • Smaller ecosystem of extensions compared to Chrome
  • Focused on macOS and Windows, with limited iOS support

DataGrail

  • No pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
  • Automated fulfilment only works for systems with a supported connector, so homegrown applications and legacy databases still need manual handling, and those are usually where the awkward data lives.
  • Discovery works by observing integrations and traffic patterns, so genuinely isolated systems, offline data and files on employee machines remain invisible and outside the data map.
  • It is narrower than the enterprise privacy suites, lacking the assessment, third-party risk and wider GRC modules a large regulated organisation will also need, so it may be one of two platforms rather than the only one.
  • Deletion automation is irreversible and mistakes are unrecoverable, so teams need real confidence in identity verification before enabling it, and that caution often keeps deletion semi-manual for months after purchase.
