Help with NullDisk

Contact support@nulldisk.app for purchase, activation, refund and app questions. Include your order identifier when asking about a purchase. Never email us your card details, passwords or unrelated file contents.

We respond to support requests within three business days.

Missing license email?

Check your spam folder, then email support from the address used for your purchase. Include your order identifier if you have it. Existing license owners do not need to buy again.

Activation

Paste your complete license code into NullDisk → Settings → License in the direct edition. Activation is offline. If a code is rejected, check that you copied the whole code and contact support with the app version.

Team purchases

Team licenses cover 1–100 seats as described on the pricing page. The purchasing organization owns the code and can reassign covered seats. Contact us for larger packs. Team packs use the same support service as personal licenses.

App Store purchases

Reinstall using the Apple account that purchased NullDisk. Apple manages App Store receipts and refunds. The website’s license recovery applies to direct Creem purchases.

Refunds

For a direct supporter purchase, contact us within 30 days with your order details. Statutory consumer rights remain unaffected. Refunds do not affect free access to app features.
