TZA Privacy Policy

Last updated: November 4, 2026

TZA ("the app") is published by BY COTTAGE S.R.L., operating as Coopmade ("we", "us"). This policy explains what the app does with your information.

The short version

TZA does not collect, store or share your personal data. Everything you enter stays on your device.

What stays on your device

The app stores the following only locally on your iPhone:

  • Workouts, sets, reps, weights, notes and routines
  • Body measurements and profile details you choose to enter (such as height, birth date, sex, goal weight)
  • Progress photos, kept inside the app's private storage
  • App settings, such as language, units and reminders

We have no access to this data. We do not operate a server that receives it, and the app does not require an account.

Permissions the app may ask for

  • Camera: to take progress photos and workout photos you choose to share.
  • Photo library: to import progress photos you pick, and to save the workout images you choose to share. Imported photos are copied into the app's private storage.
  • Face ID / device passcode: to protect your progress photo vault. Authentication is handled by iOS. We never receive or store biometric data.
  • Notifications: to send workout reminders. Reminders are scheduled locally on your device. We do not use push notification servers.

You can change any permission at any time in iPhone Settings → TZA.

Analytics, advertising and tracking

TZA contains no analytics, no advertising and no third-party tracking tools. We do not track you across other companies' apps or websites.

Sharing and exporting

When you export a CSV file or share a workout image, the data goes where you send it, using the iOS share sheet. We do not receive a copy.

Purchases

If you buy TZA Pro, the payment is handled entirely by Apple through the App Store. We do not see or store your payment details.

Children

TZA is not directed to children under 13 and does not knowingly collect any information from anyone.

Data retention and deletion

Your data lives on your device until you delete it. Deleting the app removes all of its data. Because we do not hold your data, there is nothing for us to delete on our side.

Your rights

Since we do not collect or process your personal data, there is no personal data of yours on our systems to access, correct or erase. If you have questions about your privacy, contact us at the address below.

Changes to this policy

If we change how the app handles data, we will update this page and the "Last updated" date before the change takes effect.
