Privacy Policy — Pourglass
Last updated 19 August 2026 · applies to the Android app ai.nextad.pourglass
Pourglass is a puzzle game. It has no accounts, no sign-in and no social features,
and it never asks you to type in anything about yourself. This page describes the
only data it does handle.
What stays on your device
Your progress — which levels you have cleared, your best move counts, your coins,
your items and your settings — is stored on the device only. It is not uploaded, it is
not backed up to us, and we cannot see it. Uninstalling the app deletes it.
What is collected, and by whom
The app includes two third-party SDKs. Neither collects your name, email address,
phone number, contacts, photos, files or precise location.
| Service | What it collects | Why |
|---|
Google Analytics for Firebase
(Google LLC) |
A randomly generated app instance ID; device model, operating system version,
language and country; and in-app events — an app open, a level cleared and how many
moves it took, a new furthest level, a tutorial finished, a chest opened, and when a
hint or extra tube was reached for. Approximate region is derived from the IP
address; the IP address itself is not retained by us. |
To understand how the game is actually played, so levels and difficulty can be
improved. |
Adjust
(Adjust GmbH) |
Your Google Advertising ID (GAID), IP address, device model and operating system
version, install and session timestamps, the Google Play install referrer, and the
same in-app events listed above. |
Attribution only: to tell which advertisement or link an install came from, so
advertising is not paid for twice. It is not used to build a profile of you or to
target you with advertising inside this app. |
Both SDKs send data over the network. No other data leaves the device.
Advertising
Pourglass shows no advertisements. There are no interstitials, no banners and no
rewarded videos, and no advertising network is embedded in the app. The Advertising ID
permission is present because Adjust uses that identifier for install attribution, as
described above.
Purchases
Pourglass sells nothing. The coins in the game are earned by clearing levels and
cannot be bought. There is no in-app billing in this version, so no payment information
of any kind is collected or handled.
Notifications
If you allow it, the app schedules one reminder a day, at 19:00 on your device's own
clock. It is scheduled and delivered entirely on the device — nothing about it is sent
anywhere, and no push service is involved. You can turn it off in the app under
Settings, or in your Android notification settings.
Children
Pourglass is not directed at children under 13, and we do not knowingly collect data
from them. If you believe a child has provided data to us, contact us and we will delete
it.
Your choices
- Reset or delete the advertising identifier. Android Settings →
Privacy → Ads lets you reset your Advertising ID or delete it entirely. Deleting it
stops Adjust from receiving it.
- Opt out of analytics. Uninstalling the app stops all collection.
If you would like your data deleted while continuing to play, write to us at the
address below and we will request its deletion from both services.
- Delete everything. Uninstalling the app removes all local data.
Android Settings → Apps → Pourglass → Storage → Clear data does the same without
uninstalling.
Retention
Analytics and attribution data are retained by Google and Adjust under their own
retention schedules — currently up to 14 months for Google Analytics event data and up
to 24 months for Adjust. We do not operate a server of our own and hold no copy of your
data outside those two services.
Third-party policies
Changes
If this app starts showing advertisements or selling anything, this page will be
updated before that version ships, and the date at the top will change.
