Privacy Policy

Effective date: 14 September 2026

Summary

Stackful is designed so that the supplement information you enter stays on your iPhone.

Your data is only stored on this iPhone.

There is no Stackful account and no app backend, and the app contains no advertising or analytics. If you subscribe to Stackful Plus, the subscription transaction is processed by Apple.

This policy covers the Stackful app for iPhone, version 1.0, and this website.

Information stored by the app

The information you enter into Stackful can include:

This information is stored locally inside Stackful’s app container on your device. Stackful does not transmit this supplement information to the developer.

Like other app data, it may be included in iPhone backups that you create with iCloud Backup or on a computer, according to your Apple settings. Stackful does not access those backups.

If you add a retailer link and open it, the link opens in your web browser, and that website’s own privacy practices apply.

Information the developer does not collect through Stackful

The Stackful app has:

Apple, as the provider of iOS and the App Store, and Cloudflare, as the host of this website, process some technical information under their own policies, as described below. If you choose to share analytics with app developers in your iPhone settings, Apple may provide the developer with aggregated usage statistics and crash reports through its developer tools. Stackful does not add its own analytics.

Retention and deletion

Support email

If you choose to contact espen.lund95@icloud.com, the developer receives your email address, your message and any information you decide to include.

This information is used only to respond to you, investigate the issue you report, keep necessary correspondence and meet legal obligations.

Please do not email medical information or other sensitive personal information that isn’t needed to help you.

You can ask for your support correspondence to be deleted by writing to the same address. Some information may need to be kept for legitimate legal or administrative reasons.

Website hosting

This website is hosted by Cloudflare Pages. To deliver and protect the site, Cloudflare may process limited technical information, such as:

Stackful does not add analytics, advertising trackers, cookies or contact forms to this website. Cloudflare’s handling of information is described in the Cloudflare Privacy Policy.

Children

Stackful does not knowingly collect personal information from children through an account or backend, because the app has neither.

Changes to this policy

This policy may be updated when Stackful’s functionality or legal obligations change. The effective date at the top of this page will be updated when it does.
