Expy Profit Calculator

Expy Profit Calculator Privacy Policy

Last updated: October 2026

Summary

Expy makes no network connections. Fee rules and currency data are built into the app, and your saved products stay on this device. There are no accounts, ads, analytics or in-app purchases.

This policy covers the Expy Profit Calculator app for iPhone and iPad, published by mk0.net, an independent app studio. It is written from what the app actually does in its code. Questions: hello@mk0.net.

What we receive

Nothing. The app does not connect to any server, ours or anyone else's.

What stays on your device

  • Your saved products, costs, fee settings and results are stored on this device.
  • Your cost templates, currency, seller country and other settings are stored on this device.

We cannot see this data. It is not uploaded to us.

Permissions the app may ask for

  • Notifications: Asked only if you turn on reminders to review your product pricing. They are created on your device.

Every permission is optional and can be changed later in the iPhone Settings app. Features that need a permission you decline simply stay unavailable.

Data that leaves your device

None. The app does not send your data anywhere.

Ads, tracking and analytics

No ads, no tracking across other apps or websites, and we never sell your data. The app contains no analytics SDK.

Account

No account needed. There is no sign-up and nothing to log in to.

Children

Expy Profit Calculator is not directed at children under 13, and we do not knowingly collect personal information from children.

Keeping and deleting your data

Delete saved products inside the app. Export them as CSV or JSON first if you want a copy. Deleting the app removes all of its data from this device.

Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA or KVKK), you have the right to access, correct, export or delete your personal data. Because the app keeps your records on your own device, you can do most of this directly in the app or by deleting it. For anything else, or for data held by a service listed above, email hello@mk0.net and we will help within 30 days.

Changes to this policy

If the app starts handling data differently, we will update this page and the date below before the change ships.
