Hourlit Privacy Policy

Effective date: 2026-11-03

Hourlit is a study timer: you tap a subject to start the clock, take breaks, and see your study time by day, week and month, with a daily goal, a streak, a D-day countdown, reminders and a home screen widget (the "app"). It is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Hourlit has no account system, no study groups and we do not run a server for it.

Data stored on your device

Your subjects, study sessions (start and end times), daily goal, D-day and settings are stored only on your device. They are not sent to us. Uninstalling the app deletes this data from your device. If device backup is turned on, Android's standard app backup may include this data in your own Google account backup. That backup is controlled by you and Google, not by us.

Sharing a study card

When you tap Share today's card, the app creates an image of today's study time on your device and opens the Android share sheet. Nothing is sent unless you choose an app to share it with; what happens next is up to that app.

Permissions the app asks for and why

• Notifications (optional). Used to show the running study timer (on the lock screen and notification shade, with a Stop button) and for a gentle reminder in the morning and evening. You can decline and every feature still works.
• Run at startup. Lets reminders and the home screen widget come back after your phone restarts or the time zone changes.
• Vibration. Used only for reminder notifications if you keep notification vibration on.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. Everything else in the app works offline.

The app does not request the camera, microphone, storage or media permissions, location, your contacts or usage access, and it does not block or read other apps.

Information collected automatically

When you use the app, third-party SDKs used for advertising may collect some information automatically, including:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as your device's operating system and model, and ad performance data

The advertising SDK collects this information and shares it with Google (AdMob) and its advertising partners for advertising, analytics, fraud prevention, security and compliance. It is encrypted in transit. The app itself does not send your subjects, study sessions or other app data off your device, and we do not link the advertising data to them.

Advertising

The app shows advertisements from Google AdMob:

• a banner at the bottom of the screens (not on the focus timer screen and not while you edit a subject, a session or your D-day)
• an ad when the app starts from the launcher
• full-screen ads only after you finish something: when you finish a study session and open its result, and when you save a session you added or edited by hand
• an ad in the exit dialog
• optional video ads you can choose to watch from Settings to see fewer ads for 24 hours

A full-screen ad never appears while the focus timer is running, when you start a subject, from the widget or notification, or when you switch tabs. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. In the European Economic Area (EEA), the United Kingdom and other regions where required, the app shows a consent form through Google's User Messaging Platform (UMP) before personalized advertising data is used. If you decline, you are shown non-personalized ads instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Children

Hourlit is a general-audience app and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device, so you control it directly: you can edit or delete sessions and subjects in the app, and uninstalling the app removes everything the app stored. Depending on where you live (for example under the GDPR in the EEA/UK or the CCPA in California), you may also have rights over data processed by advertising SDKs. You can exercise your ad choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
