Sleepy Capy (Sleep Sounds) — Privacy Policy

Last updated: 2026-09-28

This Privacy Policy explains how the Sleepy Capy (Sleep Sounds) app (“the app”) for Android handles information. The app is developed and published by DOK Tech Dev (“I”, “me”).

Summary

The app works offline and does not require an account. I do not collect your personal information, and the app does not send what you create in it (your sounds, mixes and settings) anywhere. The free version shows small banner ads served by Google AdMob, and Google collects some data to show them (see “Ads”). Sleepy Capy Pro, a one-time purchase, removes the ads; with Pro, the ads service is never started. Purchases are handled by Google Play.

Information the app stores on your device

To work, the app saves a small amount of information only on your device:

  • the sounds you last selected, the volume of each and the timer;
  • the mixes you save, with the names you choose;
  • timer options, such as the fade and your last custom duration;
  • the theme you picked;
  • your bedtime reminder setting and its time.

This information never leaves your device through the app, and I have no access to it. If your Android backup is on, Android may include it in your Google backup, which Google handles. You can delete it at any time by clearing the app’s data in your Android settings or by uninstalling the app.

Ads

The free version shows banner ads on the sound list and on the Settings screen, using Google AdMob. There are no full-screen ads. To show and measure ads, Google AdMob may collect and use, for example:

  • your device’s advertising ID;
  • your IP address, from which an approximate location can be inferred;
  • device information, such as model, operating system version and language;
  • how you interact with the ads;
  • diagnostic and performance information.

Google may use this information to show ads that are personalized to you. I do not receive this data about you individually. Where the law requires it (for example, in the European Economic Area, the United Kingdom and Switzerland), the app asks for your consent with a consent form before ads are requested, and you can change your choice later where the form allows it.

You can also control ad data on your device: in Android Settings > Privacy > Ads you can delete or reset your advertising ID and opt out of ads personalization.

If you buy Sleepy Capy Pro, the ads service is not started at all.

To learn more, see Google’s Privacy Policy and How Google uses information from sites or apps that use its services.

In-app purchases

Sleepy Capy Pro is a one-time purchase made through Google Play. Google processes the payment; I do not receive your payment details. The app asks Google Play, on your device, whether your account owns Pro, so it can unlock the features, and lets you restore a purchase you already made.

Notifications

The app can send you a daily bedtime reminder if you turn it on and allow notifications. The reminder is scheduled on your device and can be turned off at any time.

Information I do not collect

Outside of the ads described above, the app does not collect, store on a server, share or sell:

  • your name, email address or any contact information;
  • your precise location;
  • audio from your microphone (the app does not use the microphone);
  • your contacts, photos or files;
  • usage statistics or analytics, or crash reports.

Permissions

The app requests only the permissions it needs:

  • Playback in the background and with the screen off: a foreground media playback service, a wake lock and notification controls, used only to play sounds.
  • Notifications: for the playback controls and the optional bedtime reminder.
  • Restart of the device: so the bedtime reminder is scheduled again after a restart.
  • Internet and network state, and the advertising ID: used by the ads service, and only in the free version.
  • Google Play billing: for the Pro purchase.

Google Play and Google AdMob

The app is distributed through Google Play, and Google may collect information in connection with downloads, installs, updates and purchases, as described in Google’s Privacy Policy. The only other third-party service in the app is Google AdMob, described above.

Children

The app is not directed at children, and I do not knowingly collect information from children.

Your rights

Because I do not collect or hold personal data about you, there is no personal data for me to access, correct or delete. For the data that Google collects to show ads, Google is responsible, and you can use the controls above. If you are in Brazil (LGPD), the European Union or the UK (GDPR), or another region with data protection laws, you can still contact me with any question.

Changes to this policy

If the app changes in a way that affects your privacy, I will update this policy and the date above before releasing that version.
