❓ Frequently Asked Questions
How can I be sure my videos aren't uploaded?
Open your browser's DevTools (F12) and check the Network tab while compressing. You'll see zero upload requests to any server.
What happens if I close the browser tab?
All video data is immediately cleared from memory. There's no recovery possible because nothing was ever stored anywhere.
Can you recover deleted videos?
No, it's technically impossible. We never receive your videos, so we cannot store, backup, or recover them.
Is this safe for confidential business videos?
Yes, because your videos never leave your computer. It's safer than email, cloud storage, or any other online service.
Do you use analytics or tracking?
Only basic Microsoft Clarity analytics for performance monitoring. It cannot and does not capture video content or file information.
What about legal compliance?
Since we don't process personal data, we automatically comply with GDPR, CCPA, HIPAA, and other privacy regulations.
