Questions

Frequently asked.

Quick answers. If you still need help, feel free to reach out.

Does it handle Canadian taxes automatically?

Yes. GST, HST, PST, and QST are calculated automatically based on the province you set. No manual tables or external lookups needed.

Can I start free and upgrade later?

Absolutely. The Starter plan is free forever with no credit card. Upgrade to Offline or Online whenever it makes sense for your workflow.

What is the difference between Offline and Online?

Offline is a one-time purchase with device-local storage. Online is a monthly subscription that adds cloud sync, backup across devices, and access from any phone or tablet.

Is my data safe on the free plan?

Yes. On the Starter or Offline plans, data lives only on your device. Nothing is sent to our servers unless you sign up for cloud sync.
