Team reminder-free license

$9.99 per seat, paid once. Your organization owns the license and may reassign seats. Use one team code for the covered users or shared workstations; ordinary workplace use remains free.

Total: $49.95 once. The final tax and currency details appear at checkout.

For more than 100 seats, contact support. Team packs include reminder removal and organization ownership. Deployment consulting, response-time guarantees, and priority support are not included.

Prefer the Mac App Store?

The App Store edition is a one-time paid purchase with no support reminders. The free direct download remains available here. Availability and the local store price will appear here when Apple approves the listing.

Already bought NullDisk?

Existing direct licenses and lifetime purchases retain their benefits. You do not need to purchase again to use the app. Contact support if you need help finding or activating your license.

What does “permanent” mean?

Your supporter license has no expiry and removes reminders in compatible direct editions. It does not include a promise of unlimited future updates, new products, or ongoing personal support. Every app feature remains available without a purchase.

Delivery and refunds

A direct purchase includes a digital reminder-removal license code, provided on the purchase confirmation page and by email after verified payment. Direct checkout uses Creem as merchant of record for payments and tax invoices. There is no physical shipment. Disk contents are not needed for licensing.

Direct licenses come with a 30-day refund window. Email support@nulldisk.app with your order details. Refund terms preserve statutory consumer rights.
