Security and file safety
How VersionFixer protects uploaded files, conversion jobs, payments, and worker access.
Every job is stored in a private folder that is blocked from direct web access.
Each conversion receives a separate job directory for input, work files, logs, and output.
Temporary job folders are scheduled for cleanup after 30 minutes by default. A failed conversion placed into private manual review may be retained for up to seven days solely to complete that review.
Payments are processed securely by Lemon Squeezy, VersionFixer's Merchant of Record. VersionFixer does not store raw card numbers, CVC codes, or payment-wallet credentials. Available payment methods are shown securely during checkout.
Desktop conversion workers connect with scoped API keys instead of public open ports.
The public service uses HTTPS, restricted administration access, private worker networking, and monitored recovery procedures.
File lifecycle
Uploads are stored only inside private VersionFixer job storage. Each job receives separate input, work, logs, and output directories, then is scheduled for cleanup after 30 minutes. A failed conversion in private manual review may retain its source for up to seven days solely to complete that review.
Payment safety
Payments are processed securely by Lemon Squeezy, VersionFixer's Merchant of Record. VersionFixer stores the plan, credit, and checkout references required to operate the service, not raw card numbers, CVC codes, or payment-wallet credentials.
Worker isolation
Desktop conversion workers use scoped API keys, private network rules, and per-format queues so one failed job cannot affect another conversion.
Abuse protection
Executable extensions, dangerous filenames, unsupported formats, and excessive request rates are rejected before a job is created.
