Free version and membership
What can I use for free?
Edit locally, preview documents with a SAMPLE watermark, and back up your data. Each device can export 1 watermarked single-document PDF per calendar month. The free plan allows 10 products, shows the latest 10 history records, and saves 1 company template. Signing out or deleting an account does not reset the monthly export allowance.
What does annual membership add?
Unlimited PDF exports without watermarks for five document types, 11 document languages, combined PDF and customs data exports, and no plan quantity limits for products, history, or company templates. See the full comparison.
How does the 7-day trial work?
A trial is shown only when the store offers it and confirms that your account is eligible. Check the trial duration and annual renewal price before confirming. To avoid an Apple trial charge, cancel in the original store at least 24 hours before it ends. Account deletion does not cancel the trial.
Are my records lost when membership expires?
No records are deleted because the free limits apply. Older history remains on the device and in full backups and can be viewed again with active membership. Existing products and company templates above the limits stay usable; additions are restricted. Existing products can be edited, and a company template can be updated under the same name.
