Question 1

How do I cancel my subscription?

Accepted Answer

Subscriptions are managed entirely through your App Store or Google Play account. Open your store account settings, find Hydrographic Survey under subscriptions, and choose cancel. You will keep access until the end of the current billing period.

Question 2

How does the free trial work?

Accepted Answer

You get full access to every feature for 7 days, free. If you do not cancel before the trial ends, it automatically converts to a paid subscription at the plan you chose.

Question 3

Is my survey data backed up to the cloud?

Accepted Answer

No. Hydrographic Survey is fully offline and stores all data on your device. To keep a copy, export your surveys as PDF, CSV, or JSON and save or share them wherever you like.

Question 4

Can I use the app with no internet connection?

Accepted Answer

Yes. The app is designed to work entirely offline — no signal, login, or cloud is required to record readings, run calculations, or export your data.

Question 5

What happens to my data if I delete the app?

Accepted Answer

Because data is stored locally, deleting the app removes its survey data from your device. Export anything you want to keep before uninstalling.
