Glassful: Water Reminder

Effective: October 2026 · 한국어

1. Information We Collect

No personal information. There is no sign-up, no login and no account of any kind. Your drink log, daily goal, reminder schedule and settings stay on your device. Glassful is not a medical device and gives general reference values only. The app contains no advertising.

No advertising identifier (GAID) is requested or used. No ad SDK is present.
No third-party analytics or crash-reporting SDK is present in the app.
Anonymous usage events only. The app sends a fixed, minimal set of anonymous events to our server (first launch, first successful use, whether the plan screen was shown and from where, purchase started / completed / cancelled / failed, restore, and a daily "still installed" ping on day 1 and day 7). Each event carries only an install identifier the app generates at random, an app tag, the event name and a timestamp. It never contains your drink log, amounts, goal, body weight, name, e-mail, device identifiers or advertising ID. We use it solely to see where people drop off. Raw events are kept for up to 90 days, then only aggregate counts remain.

2. Where Your Data Lives

Data	Purpose	Stored
Drinks you log (amount, drink type, time)	Showing today's progress, history and charts in the app and widgets	On your device
Daily goal, and body weight / activity if you use the goal calculator	Suggesting and showing your daily goal	On your device (weight is used only for the suggestion)
Reminder schedule, glass presets, widget and app settings	Reminding you and showing the app the way you set it	On your device
Glassful Pro entitlement	Unlocking what you bought and restoring it	On your device (verified with Google Play)
Anonymous usage events (random install identifier only)	Seeing where people drop off	Our server — raw events for up to 90 days, then aggregates only

Health information. Water intake is health-related information. It never leaves your device unless you export it yourself, is not shared with anyone, and is not connected to Health Connect or any other health service.

Notifications. Reminders are local notifications scheduled on your device. The app asks for notification permission only when you turn reminders on. No push service is used.

Backup. Android's built-in app backup may copy the app's data to your own Google account backup if you have that enabled on your device; that is governed by Google, not by us. You can also export your log to a JSON or CSV file — the file goes only where you send it.

The only time your log leaves the app is when you tap Export and choose where to send it — you pick the destination, and we are not part of it.

3. Third-Party Services

The app contains no advertising or analytics SDK. The only third-party component is Google Play Billing, which runs the purchase itself. The only external party involved is Google, and only for what you initiate:

In-app purchases and subscriptions — processed entirely by Google through your Google Account. We never see your payment details and receive no personal data from a purchase. Subscriptions are managed and cancelled in Google Play.

Google's handling of that data is governed by the Google Privacy Policy.

4. Overseas Transfer of Personal Data

We transfer no personal data abroad. The anonymous usage events in section 1 are received on Cloudflare infrastructure (which may be located abroad) and contain no personal data.

5. Advertising and Tracking

No ads. The app displays no advertising of any kind.
No tracking. Nothing about you is tracked across apps or websites. No advertising ID is read.

6. Children

This app is for a general audience and is not primarily directed at children under 13. It collects no personal data from anyone, including children.

7. Your Rights

Deletion — deleting the app removes all local data. Files you exported yourself remain where you put them. Anonymous usage events cannot be linked back to you and are discarded after 90 days.
