I wrote to these guys and explained my situation. This is what was sent back to me:

Hi David,

Thank you for reaching out. We understand how serious this is if you have paying subusers and have integrated VidPowr into your business.

Let me clarify directly. VidPowr will remain fully operational until March 31, 2026, including all subuser access and functionality. After that date:

Subuser accounts will no longer be accessible.
Hosted videos will stop functioning.
Embedded players will no longer load.
The platform infrastructure will be retired entirely.

There is no automatic migration to a new version.

Because you operate with subusers, I recommend beginning a structured transition plan as soon as possible:

• Download all hosted video assets
• Export any client lead data
• Identify replacement hosting infrastructure
• Communicate proactively with your subusers

Separately, for larger agency operators, we are evaluating whether a limited self-hosted licensing option may be feasible for those who require infrastructure continuity. This is not finalized, but if that would be relevant to you, let me know, and I can note your interest.

I know this impacts real business operations, and we want to ensure you have clarity and time to plan properly.

Kind Regards,
