Frequently Answered Questions
Clear answers regarding client-side privacy, file boundaries, and runtime operations.
Are my confidential files ever uploaded to your servers?
No. OMNIKITY utilizes client-side WebAssembly, HTML5 Canvas APIs, and Web Workers for basic utilities. When you drag a document or image onto a tool, the data is loaded straight into your local browser memory space. You can verify this by disconnecting your internet connection—the tools will continue processing seamlessly.
Is there a maximum file size restriction?
Because execution occurs in your own browser for client-side tools, limits are dictated solely by your computer's RAM and browser thread constraints. Free tier cloud workers support up to 50MB per file with automatic 30-minute purging, while Pro accounts support up to 500MB and Business accounts support 2GB.
Can I use these tools for commercial work and business invoicing?
Yes, absolutely. All generated deliverables (PDFs, invoices, formatted graphics, converted audio) carry zero watermarks and are 100% owned by you. OMNIKITY claims zero copyright or licensing over your files.
What is the cancellation and refund policy?
You have 100% autonomy with 1-click self-serve cancellation at any time from Dashboard > Subscription. If you encounter any technical issues or accidental renewal, refund requests must be requested within 48 hours by emailing support@omnikity.com or visiting our Refund Policy page.
