Supported platforms
Crestora Labs applications currently run on Windows. Please ensure your system meets the minimum requirements listed on each product's page.
A macOS version is not currently available; we may add support for additional platforms over time.
Update policy
Our apps are designed to stay current automatically so you always have the latest features and fixes.
Automatic in-app updates
Applications check for and install updates automatically. In most cases updates apply in the background with minimal interruption.
Versioning
We follow semantic versioning (MAJOR.MINOR.PATCH): major versions may introduce significant changes, minor versions add features in a backward-compatible way, and patch versions deliver fixes.
Security & mandatory updates
Some updates address security issues or are otherwise required for continued operation. These may be applied automatically and, in certain cases, may be required before you can continue using the app.
Offline grace windows
Our apps validate your license periodically. If your device is offline, the app continues to work during a grace window before re-validation is required:
- Individual plans: approximately 10 days offline grace.
- Corporate plans: approximately 14 days offline grace.
Once you reconnect, the app re-validates automatically.
Release cadence
We ship updates regularly, with new features and fixes delivered as they're ready.
End-of-life & version support
Because updates are delivered automatically, most users always run a supported version. Older versions may stop receiving support or fixes over time, and may eventually be required to update to continue working.
Reporting a bug or security issue
To report a bug, email [email protected] with the details listed under How to get support above.
If you believe you've found a security vulnerability, please email [email protected] with the subject line "Security" and a description of the issue. Please give us a reasonable opportunity to investigate and address the issue before disclosing it publicly.
