Privacy Policy

Last updated: May 2026

1. Who we are

Mintlane is an independent mobile app studio based in Germany, operated by Stefan Hirche. We build free, focused mobile applications for Android and iOS. This privacy policy applies to the website at mintlane.io and all Mintlane mobile applications, including Medifix.

2. Our approach to data

Mintlane apps are designed to run standalone — without accounts, without servers, and without your data leaving your device unless you explicitly choose otherwise. This is a core architectural decision, not a policy afterthought.

We do not build user profiles. We do not sell data. We do not serve tracking-based advertising.

3. This website

The mintlane.io website collects no personal data. There are no analytics scripts, no tracking pixels, and no cookies beyond what is technically necessary to serve the page. The dark/light mode preference is stored locally in your browser only.

4. Medifix — specific notes

Medifix stores all medication and intake data locally on your device using an encrypted on-device database. No medication data is transmitted to Mintlane or any third party.

If you choose to enable the optional cloud backup feature, your data is encrypted on your device before upload and stored only in your personal Google Drive or iCloud account. Mintlane has no access to this data at any time.

Medifix requests the following device permissions:

• Notifications — to deliver medication reminders
• Battery optimisation exemption — to ensure reminders are not suppressed by the operating system
• Biometric authentication (optional) — for app lock via Face ID or fingerprint

None of these permissions are used to collect or transmit data.

5. Contact data

If you email us at hello@mintlane.io, we will use your email address and message content solely to respond to your enquiry. We do not add you to any mailing list and we do not share your contact details with third parties.

6. Your rights (GDPR)

If you are located in the European Union, you have the following rights regarding any personal data we may hold:

• Right to access — you can ask what data we hold about you
• Right to rectification — you can ask us to correct inaccurate data
• Right to erasure — you can ask us to delete your data
• Right to restriction — you can ask us to limit how we use your data
• Right to object — you can object to processing based on legitimate interests
• Right to data portability — you can ask for your data in a portable format

To exercise any of these rights, contact us at privacy@mintlane.io. Given the minimal data we collect, most requests can be fulfilled within a few days.

7. Data retention

We retain email correspondence for up to 24 months for support continuity, after which it is deleted. We hold no other personal data.

8. Changes to this policy

If we make material changes to this policy, we will update the "Last updated" date at the top of this page. We do not send unsolicited emails to notify you of changes.
