Privacy policy: Alarm Clock Ultimate

Last updated 29 September 2026

Alarm Clock Ultimate is an Android app published by Nessaid Android Studio. It has alarms, timers and stopwatches, and can show your calendar's upcoming events. This policy explains what it does and does not collect.

What we collect: nothing

There is no account, no sign-in and no server of ours. We never receive your alarms, your calendar, your settings or anything else from the app. There is no analytics, and crash reports are never sent automatically; see below.

Your calendar

The calendar pane is optional. If you open it and allow access, the app reads your upcoming events for the next 14 days, and only what it needs to show them: each event's title, start and end time, whether it lasts all day, and the colour and name of its calendar. It never reads an event's description, location or guests, and it never changes your calendar.

To let you choose which calendars to show, it also reads the list of calendars on the phone, including the account each one belongs to, which is often an email address. That is used only to label the list on screen.

Events are read each time the pane is shown and are not stored. If you tap an event to make an alarm for it, the event's title is filled in as the alarm's name, which is saved like any name you type. You can disconnect the calendar in the app at any time. On Android 13 and later, that also gives the permission back.

What stays on your device

• Your alarms, timers and stopwatches: names, times, repeat schedules, sounds and the other settings for each, and your laps.
• Alarm history: a record of each time an alarm went off, with its name, when it was due, when it rang, how it ended, and the phone settings that affect alarms, such as volume, Do Not Disturb and battery saving. A more detailed log of each alarm is on by default and can be switched off or cleared in Settings. These records are kept until you clear the app's data or uninstall it.
• Your settings, including vacation dates and which calendars to hide. If you set an admin lock password, only a scrambled one-way version of it is kept, never the password itself.
• Crash reports, if the app ever crashes: the time, the app and Android versions, the phone's make and model, whether something was ringing, and the technical error details. They never include your alarm names, times or sounds. The newest eight are kept.
• Small records the app keeps for itself: when each permission was last seen allowed, and when a full-screen ad was last shown.

All of this is in the app's private storage, and uninstalling the app deletes it.

Crash reports

A crash report stays on your phone unless you send it. Settings lets you send one through any app you choose, such as email, or discard it. Nothing is sent automatically, and there is no crash reporting service.

Sounds

You choose alarm sounds from Android's own sound picker, or pick an audio file with the system file picker. The app gets access only to the file you picked. It cannot browse your music or other files.

Backups

Your own backup file. Settings can save a backup file to wherever you choose, and load one back. It contains your alarms, timers, stopwatch names and settings. It does not contain alarm history, crash reports, the admin lock or calendar settings. The file goes only where you put it.

Android's backup. If backup is switched on in your phone's settings, Android includes one file from the app in your Google account backup, and when you move to a new phone. That file holds the same things as the backup file above, and nothing else. It is Android's backup, stored in your Google account, and we cannot see it. After a restore, the app asks before loading it.

Sharing and links

The About screen can share a link to the app's Play listing, and open the app's listing so you can rate it. The app never asks you for a rating by itself. Nothing is shared unless you tap to share it and pick where it goes.

Spoken alarms

An alarm can speak aloud using your phone's text-to-speech engine. Which engine that is, and how it works, is set in your phone's settings, not by this app.

Advertising

The app shows banner ads on the main screen, and on the screens for editing an alarm or a timer and for settings. Occasionally it shows a full-screen ad when you leave one of those editing screens, or after you dismiss an alarm. Both kinds come from Google AdMob.

Ads are never shown on the screen of a ringing alarm, over the lock screen, or in widgets and notifications. No full-screen ad appears while something is ringing, when an alarm or timer is about to go off, or in the first two days after you install the app.

Google's ad SDK sends four kinds of information to Google in order to select and measure ads: your device's advertising ID, your interactions with the ads themselves, diagnostic information about how the SDK performed, and your IP address, from which an approximate location can be estimated. The app requests no location permission and cannot see where you are; the estimate comes from the IP address every internet connection carries. The app does not pass your alarms or your calendar to the ad SDK.

That is Google's processing, not ours. We receive no personal data from it and see only aggregate performance figures. This is also what the app declares on its Google Play data safety page, and the two are meant to say the same thing.

Google Privacy Policy · How Google uses information from sites or apps that use its services

You can reset or delete your advertising ID, and opt out of ad personalisation, in your phone's settings under Google, then Ads. The alarms work the same either way; the ads simply become less relevant.

Consent, for users in the EEA, the UK and Switzerland

If you are in one of those regions, the app asks for your consent before any ad is requested, using Google's certified consent platform. If you decline, you will see non-personalised ads or none at all; the alarms work exactly the same either way. Your choice is stored on the device. To be asked again, clear the app's data in Android's app settings.

Permissions, and why

You are asked for only two of these: notifications, and the calendar if you use the calendar pane. Exact alarms, the full-screen alarm screen and battery optimisation are settings the app can take you to, where you decide. The rest are granted at install and never prompt you.

• Notifications: for ringing alarms and for running timers and stopwatches. You are asked for this on Android 13 and later.
• Calendar, read only: for the optional calendar pane, described above. You are asked for this the first time you use it.
• Exact alarms: so alarms ring at the minute you set.
• Full-screen notification: so a ringing alarm can show its own screen, even over the lock screen.
• Foreground services: to play the alarm sound, and to keep timers and upcoming alarms on time.
• Start at boot: to set your alarms again after the phone restarts.
• Ignore battery optimisation: offered so the phone's battery saving cannot delay an alarm. Only if you tap it, and Android asks you first.
• Wake lock: to keep the phone awake while an alarm is ringing.
• Vibrate: for the vibration alert.

These come from Google's ad SDK, which declares them in its own manifest:

• Internet and network state: used only to load ads and the consent form. No other part of the app uses the network.
• Advertising ID, and Android's ad services: used only by Google AdMob, as described above.
• Basic phone state: declared by the ad SDK. The app does not read it.

The app can also flash the phone's torch as an alarm alert, which turns the light on without using the camera, and read the motion sensor for the shake-to-dismiss option. Neither needs a permission, and motion readings are not stored or sent anywhere. The app does not use your location, contacts, camera or microphone.

Children

The app is not directed to children under 13, and we do not knowingly collect information from them.

Selling data

We do not sell your data. We have none to sell.

Changes

If this policy changes, the date at the top changes with it, and the current version is always at this address.
