## What is Stage1Files?

Your ECU file workflow, from your iPhone or iPad.

Stage1Files helps automotive professionals manage compatible ECU and TCU calibration files with their Stage1Files account. Import an original read from Files, confirm the control unit, request processing and save the result back to Files.

A WORKSPACE FOR YOUR FILES
• Browse the supported ECU and TCU catalog.
• Import an original file and review detected control-unit information.
• Request Stage 1 processing for supported original files.
• Save processed files and access your processing history.
• Track account access and daily file allowances.
• Contact the team through in-app support tickets.
• Choose light or dark appearance and your preferred interface language.

BUILT FOR iPHONE AND iPAD
Use a layout that adapts to your device, with system file import and export. Your Stage1Files account connects your service access across supported devices.

ACCESS AND PURCHASES
Creating an account is free. File processing requires eligible paid access and an available daily allowance. Access and additional daily capacity are available as in-app purchases; Apple displays the applicable price and currency before confirmation.

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. It does not renew automatically or extend annual access. New additional capacity cannot be purchased when 10 days or less remain on your subscription. Daily allowances reset at the UTC day boundary and do not roll over. Restore purchases using the same Stage1Files account.

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.
