Privacy Policy

Last updated: June 20, 2026

This Privacy Policy explains how Dominik Schimpf (“we”, “us”) handles information in connection with the Archnemesis mobile application (the “App”). We built Archnemesis to protect your attention — and we treat your data with the same respect.

1. Information we process

Data that stays on your device / in your iCloud

• Your habits, goals, streaks and settings are stored locally on your device and, if iCloud is enabled, synced through your private Apple iCloud (CloudKit) account. This data lives in your iCloud — we do not have access to it.
• Screen Time & app-blocking data. Archnemesis uses Apple's Family Controls / Screen Time framework. The apps and categories you choose to block are represented by Apple as opaque, privacy-preserving tokens that never leave your device and are never readable by us.

Data we (or our processors) receive

• Product analytics. We use Mixpanel to understand how the App is used (e.g. features opened, onboarding steps, anonymized usage events and a random device/app identifier). This helps us fix bugs and improve the App. It does not include the contents of your habits or blocked-app selections.
• Purchases. Subscriptions are sold and processed by Apple through in-app purchase (our paywall is powered by Superwall). We receive confirmation of subscription status but never your card number or full payment details.
• Diagnostics. Aggregate crash and performance data may be provided by Apple if you opt in to share it.

2. How we use information

• To provide and operate the App's features (habit tracking, app blocking, personalized insights).
• To process and validate your subscription.
• To analyze and improve performance, reliability and the user experience.
• To respond to support requests.

3. What we do not do

• We do not sell your personal data.
• We do not use your Screen Time / Family Controls data for advertising, and it is not transmitted to us.
• We do not access the contents of your iCloud-synced data.

4. Sharing

We share limited data only with service providers that help us run the App — currently Apple (App distribution, iCloud sync, in-app purchases), Superwall (paywall presentation) and Mixpanel (analytics) — and only as needed to provide the service. We may disclose information if required by law.

5. Data retention

On-device and iCloud data remains until you delete it in the App or remove the App and clear its iCloud data. Analytics events are retained by our analytics provider for a limited period. You can delete your data at any time by deleting your content in the App and uninstalling it.

6. Your rights

Depending on where you live (including under the EU/EEA GDPR), you may have the right to access, correct, delete, or port your data, and to object to or restrict certain processing. To exercise these rights, contact us at archnemesisapp@gmail.com.

7. Children

Archnemesis is not directed to children under 13, and we do not knowingly collect data from them.

8. Changes

We may update this policy. Material changes will be reflected by the “Last updated” date above.
