WaterNudge Data and Deletion Guide

Effective date: July 31, 2026

WaterNudge does not require an account and Stackquiln does not operate a server copy of your hydration history. For that reason, there is normally no WaterNudge account to close and Stackquiln cannot retrieve or remotely delete on-device hydration entries.

Delete data stored on your device

Use any of these Android controls:

1. In WaterNudge, open Settings and choose Reset data to erase hydration entries and reset app preferences.
2. In Android system settings, open WaterNudge's app information and clear app storage.
3. Uninstall WaterNudge.

Resetting, clearing storage, or uninstalling permanently removes local app data from that device. WaterNudge disables Android cloud backup and device-to-device transfer for its app data.

Because Reset data restores app defaults, Crash reporting becomes enabled again after the reset. Turn Crash reporting off in Settings after completing onboarding if you want reporting to remain disabled.

Analytics and crash reporting

• Open Advertising & analytics privacy in WaterNudge Settings and withdraw the Analytics choice to disable future Firebase Analytics collection and request a reset of the app's Analytics identifier and local Analytics data.
• Crash reporting is on by default. Turn Crash reporting off separately to disable future Crashlytics collection and request deletion of reports that have not been sent. The opt-out persists across subsequent app launches.

Already submitted provider records may remain for the provider's stated retention period or legal obligations. A standard Google Analytics 4 property provides a configured 2- or 14-month retention period for user- and event-level data, while aggregated reports may remain longer. Because WaterNudge has no account and does not set a WaterNudge user ID, an already uploaded event may not be linkable to a deletion requester. Firebase states that submitted Crashlytics stack traces and associated identifiers are generally kept for 90 days before deletion begins.

Ads, consent, and public configuration

The free release uses Google-served ads. Use Privacy choices in Settings where available to revisit consent choices. The public Cloudflare configuration request does not add a WaterNudge identifier or hydration data, so Stackquiln normally cannot associate a host log with a particular WaterNudge user.

Purchases and subscriptions

Deleting WaterNudge data or uninstalling the app does not cancel a Google Play subscription. Manage or cancel subscriptions in Google Play. Google Play controls its account and transaction records under Google's policies and legal obligations.

Request provider-held or support data

Email stackquiln@gmail.com with “WaterNudge deletion request” in the subject. State:

• which optional feature was involved, such as Analytics, Crashlytics, ads, a purchase, or support email;
• the approximate date; and
• what you want deleted.

Do not send hydration logs, medical details, government identification, passwords, or payment-card information. We may request limited information only when reasonably necessary to verify or locate the request. Some information may be retained where required for security, transactions, legal claims, or compliance; if so, we will explain the applicable limitation where required.

Requests are handled within the period required by applicable privacy law. See the Privacy Policy for rights, recipients, retention, and regional procedures.
