Terms of Use
Last updated: 2026-05-25
Using DualKey means you accept the terms below.
License
The app is provided as is, licensed to you for personal, non-commercial use. Do not reverse engineer or copy it, and do not lift the encryption flow, the QR parsing, the migration tool or the interface copy into another commercial product.
Liability
Codes are produced by the standard algorithms (RFC 6238 and RFC 4226); their correctness depends on the QR code you imported from the original service. If the device clock drifts far enough, the code will be wrong, so leave system time set to update automatically. The app accepts no responsibility for being locked out of an account, or for any other loss, caused by an incorrect code, a failed backup or restore, a forgotten master password or a lost device. For important accounts, also keep the recovery codes the service gave you.
Changes
These terms may update from time to time. Changes are posted here. Continued use means acceptance.
