2. Overview of Processing

DuoLock is a landing page and iOS app for shared offline sessions. The website only processes data that is required for technical operation, basic audience measurement, and communication.

Types of data processed

• Connection data, such as IP address, browser, operating system, and access time
• Usage data, such as visited pages and referrer information
• Communication data when you contact us by email
• App-related settings that you choose in the iOS app on your device

3. Website Hosting with Vercel

This website is hosted by Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA. When you access the website, Vercel processes technical connection data to deliver, protect, and operate the site reliably.

The legal basis is Art. 6(1)(f) GDPR. The legitimate interest is the secure and performant operation of this website. For transfers to the United States, Vercel uses appropriate safeguards, including Standard Contractual Clauses, and is certified under the EU-U.S. Data Privacy Framework.

More information is available in Vercel's privacy policy: vercel.com/legal/privacy-policy.

4. Vercel Web Analytics

We use Vercel Web Analytics to understand which pages are viewed and whether the landing page works technically. This may involve processing technical information such as URL, referrer, approximate location, browser, operating system, device type, and event time.

Vercel Web Analytics is not used to track individual visitors across multiple websites. We do not use advertising or retargeting cookies on this website.

The legal basis is Art. 6(1)(f) GDPR. The legitimate interest is privacy-conscious measurement of reach and technical page views.

5. Email Contact and App Access Requests

If you contact us by email or request DuoLock access, we process your email address, the content of your message, and technical email metadata in order to respond to your request.

The legal basis is Art. 6(1)(b) GDPR if the request relates to using or preparing to use the app, and otherwise Art. 6(1)(f) GDPR.

6. DuoLock App and Screen Time Data

In the DuoLock app, you choose which apps or app categories should be paused on your iPhone during a shared offline session. This selection is handled through Apple's Screen Time and FamilyControls interfaces on your device.

Your partner does not see a list of your selected apps, app usage reports, or an activity log. A shared session only starts when both people agree.

To the extent that the app processes technical status data for session coordination, this is done to provide the app functionality. The legal basis is Art. 6(1)(b) GDPR.

7. Retention

Personal data is deleted once the purpose of processing no longer applies and no statutory retention obligations prevent deletion. Email requests are retained only for as long as necessary to handle the request and any reasonable follow-up communication.

8. Your Rights

Under the GDPR, you have rights including access, rectification, deletion, restriction of processing, data portability, objection, and withdrawal of consent.

To exercise your rights, contact hello@duolock.app. You also have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for the controller's place of business is the State Commissioner for Data Protection of Lower Saxony.

9. Changes to this Privacy Policy

This privacy policy may be updated if legal requirements, this website, or the app functionality change. The current version is always available on this page.
