Your Sinclair, or YS as it was commonly abbreviated, was a commercially published and printed British computer magazine for the Sinclair range of computers, mainly the ZX Spectrum. It was in circulation between 1984 and 1993.

Sinclair Research Ltd was a British consumer electronics company founded by Clive Sinclair in Cambridge. It was originally incorporated in 1973 as Westminster Mail Order Ltd, renamed Sinclair Instrument Ltd, then Science of Cambridge Ltd, then Sinclair Computers Ltd, and finally Sinclair Research Ltd. It remained dormant until 1976, when it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics, and adopted the name Sinclair Research in 1981.
