Countlet Privacy Policy

Effective date: 30 October 2026

App: Countlet: Tally Counter (Android, package com.aop.countlet)

Contact: onlineaop+countlet@gmail.com

Countlet is a tally counter: you make counters (for rows, reps, laps, visitors, glasses of water, anything) and count with a tap. In short: your counters stay on your phone. The app has no account and no servers of ours. The only data that leaves your phone because of the app is what Google’s ad service collects to show ads, described in section 5.

1. Information stored on your phone

Your counters: names, colours, emoji, counts, goals, sub-counters and settings for each counter.
Your counting history: when counts changed (used for the charts and statistics), and past “runs” saved when you reset a counter.
Your app settings (sounds, vibration, theme and so on).

All of this is stored in the app’s private storage, which other apps can’t read. We (the developer) never receive any of it.

2. Your phone’s own backup

Countlet allows Android’s built-in backup, so if your phone backs up to your Google account, your counters and settings are included and come back when you set up a new phone. This backup is made and stored by Android and Google under your Google account; we have no access to it. You can turn it off in your phone’s settings.

3. Sharing

Countlet has no way to send your counters anywhere: there is no account, no upload and no export. Your counters only leave your phone through Android’s own backup described above.

4. Permissions and phone features

Vibration: for the short buzz when you count. No other permissions are needed for your counters.
Speak the count (off by default): the number is read aloud by your phone’s own text-to-speech service.
Volume buttons and keep-screen-on: these only work while the app is open on a counter, and nothing is recorded.
The app has no access to your contacts, photos, files, microphone, camera or location.

5. Advertising (Google AdMob)

The app is free and shows a banner ad at the bottom of the Home and History screens (never on the counting screen). The ads are provided by Google AdMob. To show and measure ads and to prevent fraud, Google may collect and process:

device identifiers such as the Android advertising ID,
your IP address and the approximate location derived from it,
information about the ads you see and tap, and basic app and device information (for example crash and performance data of the ad software).

In the EEA, the UK and Switzerland you’re asked for consent before ads use your data for personalisation, using Google’s consent tool. You can change your choice at any time in the app under Settings > Privacy choices. Anywhere, you can reset or delete your advertising ID in your phone’s Android settings.

How Google uses this information: policies.google.com/technologies/partner-sites

6. Information we collect

None. The app has no account, no analytics and no crash reporting service of ours, and we never receive your counters, history or settings. We don’t sell any information. If you install the app from Google Play, Google may collect information about installs and crashes as described in Google’s own privacy policy; we may see anonymous, aggregated statistics in the Play Console.

7. Deleting your information

Delete any counter in the app (it’s removed for good the next time the app starts), or uninstall the app (or clear its data in Android settings) to delete everything it stored.
