Help & Contact

Kassnap Support

Quick answers for day-to-day sales—and a direct contact if something does not work as expected.

Important: Kassnap is a sales and settlement aid. It is not a TSE-enabled or certified fiscal cash register, does not process payments, and does not produce tax-compliant customer receipts.

Help and practice sale

Open More > Guide in Kassnap. You will find concise instructions and can practice a sale without saving real data.

Restore a purchase

Open More > Kassnap Premium > Restore Purchases. The unlock applies to the Apple Account that purchased or redeemed it.

14-day trial and Offer Code

The one-time trial is activated as a free Apple In-App Purchase and does not renew. An Apple Offer Code issued by the developer can unlock the same account permanently at no charge.

PDF, CSV, and backup

Open More > Data & export to create a PDF register report, CSV table data, or a JSON backup.

Team and offline operation

  1. Each of the 2–10 private iPhones needs an Apple Account with iCloud enabled.
  2. The admin iPhone configures device slots and a shared cash drawer or one drawer per device under More > Kassnap Team.
  3. Additional devices accept the private Apple invitation, select an available slot, and wait for Ready offline.
  4. Each prepared device can then record sales without internet for hours. Transactions remain stored locally.
  5. After reconnecting, open Kassnap on every device and wait for synchronization to finish. The combined total and final team closing are complete only after that sync.

Unlocking several devices

Permanent access costs €1.99 once in the German storefront and is tied to the Apple Account used. If team devices use different Apple Accounts, each account needs its own purchase or free Apple Offer Code after its trial.

Kassnap has no proprietary license-code database. Apple manages purchases, restoration, the free trial, and Offer Codes through StoreKit.

When reporting a technical issue

Please include, where possible:

  • Kassnap version and iOS version
  • iPhone model and affected area of the app
  • Steps that reproduce the issue
  • For team issues: the device role, visible synchronization status, and number of pending changes

Please do not send complete register exports or personal event data unless they are explicitly needed to investigate the issue.
