ACCESS AND PURCHASES Creating an account is free. File processing requires eligible paid access and an available daily allowance.

Starter access provides 7 days with 1 file per day and does not renew automatically. Annual access provides 1 year with up to 5 files per day and renews automatically unless canceled. Manage or cancel renewal in your Apple account settings. The annual period starts when purchased and is not added to the end of existing desktop access. You can purchase 1–10 additional daily files per purchase. Additional capacity increases your daily file allowance for the period shown before purchase.

PROFESSIONAL USE Stage1Files processes files; it does not connect to or flash a vehicle directly. Reading and installing a file require suitable external equipment and professional assessment. Compatibility depends on the original file and control unit. Use only files you are authorized to process and verify suitability and local requirements before installation.
