Hi Product Hunt! 👋
I built Arvelix to help you stay on top of contract deadlines, renewals, warranties, and recurring costs.
I wanted something simple and private: no extra account, no uploading personal contract information to the cloud.
Arvelix runs locally as a single HTML file. Download it, open it in your browser, and get started. It works offline, and your entries stay on your device.
The free version includes:
• Up to 5 saved entries
• Automatic deadline calculations
• Clear, color-coded status indicators
• Monthly and annual cost overviews
• Search, filters, and local backups
• Support for USD and GBP formats
Arvelix Pro is also available as a one-time purchase, with no subscription.
I’d love to hear how it works for you:
• Is the workflow clear and easy to use?
• What would make Arvelix more useful for managing your contracts and deadlines?
Thanks for checking out Arvelix. Your feedback will help shape what comes next!
