Privacy Policy — CatheterStack

Effective date: 2026.03.05

CatheterStack (“the App”) is developed by Solnir Consulting AB. This Privacy Policy explains what information the App collects and how it is used.

Summary

• We do not collect or store personal data from you through the App.

• The App is designed to work without creating an account and without sending user data to our servers.

• Optional tips/support payments are handled by Apple’s In-App Purchase system.

1) Information we collect

A) Data you enter in the App

CatheterStack may allow you to enter or select device configurations (e.g., catheter sizes, device combinations). This information stays on your device and is not transmitted to us.

B) Automatically collected data

We do not collect analytics, tracking data, or advertising identifiers through CatheterStack.

If this changes in future versions (e.g., we add crash reporting or analytics), we will update this policy and the App Store privacy disclosures.

C) Purchases (Tip Jar

If you choose to support development via the optional Tip Jar:

• Payments are processed by Apple using In-App Purchase.

• We do not receive or store your payment card details.

• Apple may provide us with non-identifying purchase reports for accounting (e.g., aggregated sales).

  For details, please refer to Apple’s privacy information.

2) How we use information

Because the App does not collect personal data, we do not use personal data for profiling, marketing, or advertising. Any on-device calculations are performed locally to provide the App’s features.

3) Data sharing

We do not sell, rent, or share personal information because we do not collect it.

4) Data retention

Any configurations or settings you create are stored locally on your device (if the App stores them at all). You can remove this data by deleting the App from your device.

5) Third-party content and trademarks

Device names may refer to products manufactured by third parties. All trademarks are the property of their respective owners. CatheterStack is not affiliated with or endorsed by these companies. Specifications may be compiled from publicly available manufacturer documentation and may vary by version and region.

6) Children’s privacy

CatheterStack is not directed to children and does not knowingly collect personal information from children.

7) Security

We take reasonable measures to keep the App secure. However, no method of storing information on a device is 100% secure.

8) Changes to this policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date.
