Privacy policy

Last updated: 23 October 2026

In short: The Mark My Hours app stores everything only on your device. There is no account, no server and no analytics or advertising services. Nobody but you sees your data, not even us.

This website sets no cookies and loads nothing from other servers. Our own cookieless visitor statistics (Matomo) count page views with a shortened IP address. When you visit, our host briefly keeps technical server logs.

1. Controller

The controller for the processing of personal data in connection with the Mark My Hours app and the website markmyhours.com is:

Boris Stiner
Aarestrasse 32
3600 Thun
Switzerland
Email: hello@markmyhours.com

This policy follows the Swiss Federal Act on Data Protection (FADP) and, where applicable, the EU General Data Protection Regulation (GDPR).

2. The Mark My Hours app

The app processes the following data:

All of this data stays exclusively on your device. The app has no user account and does not send this data to us or to third-party servers (for the map, see below). We have no access to your data. If a system backup is turned on for your device (for example iCloud Backup or Google Backup), the app's data may be part of that backup. You control this in your device settings, and Apple's or Google's terms apply.

Location

The app uses your device's location permission only to detect whether you arrive at or leave one of your workplaces. The operating system does this detection. For this, the app needs the "Always" permission. The app stores no routes and no movement profile, only the start and end of your entries. You can change the permission at any time in the system settings.

Map and address search

When you create or edit a workplace, you can search for an address and set the place on a map. For this, the app uses Apple Maps on iPhone, and Google Maps and Google's address search on Android. Your search term and the visible map area are sent to Apple or Google. The Google Maps module also collects technical details such as device type, IP address, crash data and a pseudonymous identifier. The map is only loaded on this screen. Your entries and working hours are never sent. Apple's or Google's privacy policy applies.

Notifications, widget and lock screen

Notifications, the widget and the lock screen display are created locally on your device. They appear on a connected watch (Apple Watch or Wear OS) because your phone forwards notifications to it.

Timesheet (PDF)

The PDF is created on your device. You decide whether, when and to whom you pass it on. Sending it is subject to the terms of the app you share it with, for example your email app.

Purchase

The trial and the purchase of Mark My Hours Pro go through the App Store (Apple) or Google Play (Google). We receive no payment details and no information about you. The app only learns whether the purchase is unlocked. Apple's or Google's privacy policy applies to the transaction.

No analytics, no ads

The app contains no analytics, tracking or advertising components. Apple and Google provide app developers with aggregated statistics (for example the number of downloads) and, if you have agreed to this in your device settings, crash reports. These contain nothing from your entries.

3. This website

Hosting and server logs

The website is hosted by cyon GmbH in Basel, Switzerland. When you open any page, your browser sends technically necessary data, which the server stores in log files:

This data is used only to run the website securely and reliably, for example to fend off attacks and to find errors. It is not combined with other data and is deleted automatically after our host cyon's short retention period; we do not analyse it. The legal basis under the GDPR is our legitimate interest in secure operation (Art. 6(1)(f) GDPR).

Visitor statistics

To see which pages are read, our own Matomo installation at matomo.borisstiner.com records which pages are opened and which buttons are clicked, which page you came from, the approximate region, browser and device type, and language. Your IP address is shortened by two bytes before it is stored. No cookie is set and nothing is stored on your device, and if your browser sends "Do Not Track", nothing is recorded. The data stays with us, is not combined with other data and is deleted after 180 days. Like the website, Matomo runs at cyon in Switzerland. The legal basis under the GDPR is our legitimate interest in improving the website (Art. 6(1)(f) GDPR).

No cookies, no third-party servers

The website sets no cookies and embeds no third-party content, so no maps, videos, social media plugins or fonts from other servers. The fonts Plus Jakarta Sans and JetBrains Mono are on our own server. The links to the App Store and Google Play lead to Apple and Google; their privacy policies apply there.

Contact by email

If you write to us, we use your email address and your message only to answer your request. We delete them as soon as they are no longer needed for this and no legal retention period applies. Emails are stored at cyon GmbH, Basel (Switzerland). The legal basis under the GDPR is Art. 6(1)(b) or (f) GDPR.

Beta test sign-up

If you sign up for the beta test on the home page, we store your email address, your phone (iPhone or Android) and the language of the page in our own admin at admin.markmyhours.com, also hosted by cyon in Switzerland. We use them only to send you the test invitation, notes about the test and, where promised, a thank-you code. We delete them after the test or, if we promised you a code, after sending it, and at any time you ask. For Android we add your address to the tester list on Google Play; for the iPhone you get a TestFlight link from Apple. Their privacy policies apply there. To keep programs from abusing the form, your browser solves a small computing task before sending (ALTCHA, on our own server). No cookies are set and no data goes to third parties for this. The legal basis under the GDPR is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time by email.

4. Processing in Switzerland

The website, server logs, visitor statistics and emails are processed in Switzerland. The European Commission has confirmed that Switzerland provides an adequate level of data protection.

5. Your rights

You can ask for information about the data we process about you, and ask for it to be corrected or deleted, for its processing to be restricted, or for it to be handed over in a common format. You can also object to processing. To do so, write to us at the email address above.

Data from the app is only on your device. You delete it by deleting the entries in the app or by removing the app.

You can complain to a data protection authority: in Switzerland to the Federal Data Protection and Information Commissioner (FDPIC), in the EU to the supervisory authority of the country where you live.

6. Children

Mark My Hours is not aimed at children and does not knowingly collect data from children.

7. Changes

We update this policy when the app or the website changes. The version published here applies.
