V. (“the app”) is an alarm clock with an ambient desk pet, published by Nguyen Quoc Viet. This policy describes exactly what V. does with data on your phone. It is short because V. does very little.
V. does not collect, transmit, or share any personal data. There is no account, no cloud, no analytics, no advertising, and no tracking of any kind. Everything V. knows about you stays on your device and is deleted when you uninstall it.
The app makes exactly one kind of network request, described under Network access below: a purchase check to Google Play.
All of it lives in a local database (Hive) in the app’s private storage. None of it is transmitted anywhere.
| What | Why |
|---|---|
| Your alarms, wake sounds, missions and bedtime | To wake you up |
| Your pet’s energy, mood and bond | To keep the character consistent between sessions |
| Your settings, including which sensors you enabled | To remember your choices |
| Sleep history — one number per minute, up to 90 nights | To show your sleep score and trend |
| Whether you purchased V. Plus | To unlock the paid features |
Uninstalling V. deletes all of it. There is no copy anywhere else. If your phone has Android’s automatic backup enabled, Android may include this data in your own Google account backup — that is Android’s backup system, not ours, and we never see it.
Every sensor below is optional. You can refuse any permission, or turn any sensor off later in Settings; V. keeps working without it.
Used to measure how loud the room is — a single volume number, like the bar on a sound level meter, so V. can react to a clap or notice music.
Audio is never recorded, never stored, never transcribed, and never transmitted. V. cannot tell what you say, only how loud it is. No audio ever leaves your device because no audio is ever kept, even momentarily as a file.
You must turn the camera on yourself; it is off when you install V. When it is on it does two things and nothing else:
Face detection runs entirely on your device, using a model bundled inside the app — nothing is downloaded and nothing is uploaded. It detects only that a face exists and a smile probability. It cannot identify you or anyone else, it does not recognise or distinguish faces, and there is no emotion model beyond “smiling or not”.
No photo or video is ever saved, encoded, or transmitted. Frames are held in memory for the moment it takes to compute those numbers, then thrown away.
If you turn on Mattress mode, Android requires the “Physical activity” permission before V. may keep a sleep-tracking service running overnight.
V. uses it only to keep reading the phone’s own accelerometer while the screen is off. It does not use Google’s activity-recognition service, does not count steps, and does not read any fitness or health data from your phone or any other app. During a mattress-mode night the microphone and camera are stopped — nothing is listening or watching in the dark.
The accelerometer (so V. reacts to being picked up or shaken, and to estimate how settled a night was) and the ambient light sensor on Android (so V. dims in a dark room). Readings are used in the moment and are not stored, apart from the one-number-per-minute sleep record described above.
V. asks to post notifications so your alarms can actually ring, and uses Android’s exact-alarm capability so they ring at the time you set rather than whenever the system finds convenient. If you deny notification permission, your alarms cannot ring — V. will tell you so on the Alarms screen rather than pretending they are set.
Sleep tracking is optional and off unless you turn it on.
When it runs, V. stores one number between 0 and 1 per minute, representing how much the phone moved. That is the entire record. No raw sensor data is kept, nothing is recorded through the microphone, and V. keeps at most 90 nights, discarding older ones automatically.
Sleep figures in V. are estimates for general wellness interest only. They are not a medical or health measurement, are not a diagnosis, and must not be used as one. V. is not a medical device.
V. requests the INTERNET permission for one reason:
Google Play Billing.
Once per launch, V. asks Google Play whether your Google account already owns the V. Plus purchase, so that reinstalling the app restores what you paid for without hunting for a “Restore” button. This request:
There is no other network traffic. No sync, no telemetry, no crash reporting, no advertising SDK, no AI or language-model service, and no background requests of any kind. V. works fully offline apart from that one check, and a phone with no signal keeps everything you have paid for.
Purchases are processed by Google Play, not by us. We never see or receive your payment details. Google’s handling of that transaction is covered by Google’s Privacy Policy. We operate no server and have no database; there is nothing for us to store a purchase in beyond the flag on your own device.
To be explicit, V. contains no code that:
V. does not request location permission and cannot determine your location.
V. is not directed at children and does not knowingly collect any data from anyone, of any age — because it does not collect data at all.
Because we hold no data about you on any server, there is nothing for us to export or delete on request — and no way for us to identify you if you asked.
If this policy changes, the “Last updated” date above will change with it, and the revised policy will be published at the same address.
