Countlet Privacy Policy

Effective date: 2026-11-02

Countlet is a tally counter app: you create counters and groups, tap + or − to count (in the app, in full screen or from a home screen widget), and see the history of your taps by day, week and month. It also has 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. Countlet has no account system and we do not run a server for it.

Data stored on your device

Your groups and counters (names, colors, step, start value, goal, automatic reset setting), every count change with its time (taps, values you type, resets and entries you add to past days) and your settings (vibration, click sound, volume buttons, keep screen on, left-hand mode, theme, reminders) 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.

Export and sharing

When you use Export CSV, the app writes a CSV file of your count history inside its private storage and hands it to the app you pick in the Android share sheet. When you use Share counters, the app creates an image of the current group (counter names and values) and hands it, with the same text, to the app you pick. The app does not upload anything by itself; what happens next is controlled by the app you choose.

Permissions the app asks for and why

• Notifications (optional). Used for a morning and an evening check-in on your counters. 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. A light tap when you count, if you keep vibration on.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. Counting works offline.

The app does not request the camera, storage or media permissions, the microphone, location or your contacts. The volume buttons are only used to count while a counter is open in full screen and that setting is on.

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 counters or count history 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
• an ad when the app starts from the launcher
• full-screen ads only after you finish something: after you save a new counter, after you export a CSV file, and when you leave the full-screen counter
• 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 you are tapping + or −, typing a value, using the widget or switching 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

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

Your rights

Your counters and count history exist only on your device, so you control them directly: you can delete any entry, counter or group 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.
