Stackbox Privacy Policy

Last updated: 29 October 2026

Stackbox is an organizational tool for keeping track of a supplement schedule. It is not medical advice. Consult your healthcare provider.

What we collect

Nothing. Stackbox has no accounts, no servers, no analytics and no advertising. The developer never receives your data, unless you choose to email us (see "If you email us").

Where your data is stored

Only on your device, in the app's private storage. It is protected by your device's built-in encryption and screen lock. The app does not add its own encryption.

Device backups

If you have turned on system backups (iCloud Backup on iPhone, Google backup on Android), your device may include Stackbox's data in those backups. Those backups are handled by Apple or Google under their terms. Stackbox itself does not send your data anywhere.

Export

When you export, the app creates an unencrypted JSON file and opens your device's share options, or copies the data to your clipboard. Where it goes is your choice; once shared, it is outside the app's control.

Import and AI instructions

The app can copy a text instruction to your clipboard so that you can ask an AI assistant of your choice to convert your existing schedule into a file the app can import. The app does not contact any AI service. Anything you paste into another service is governed by that service's terms.

Deleting your data

More → Data → Delete all data permanently deletes all Stackbox data on your device. Uninstalling the app also deletes it. Copies in system backups or in files you exported are not affected.

Family members and children

Profiles can describe family members, including children. That information stays on your device. The app is intended to be used by adults.

If you email us

If you write to us, for example with "Send feedback" in the app, we receive your email address, your message and the technical details shown in it. We use them only to reply and to fix problems, do not share them, and delete them on request. The app itself sends nothing: your email app sends the message, and you can edit or delete anything in it before sending.

Changes

If this policy changes, the new version will be shown in the app with a new "Last updated" date.
