Privacy Policy
Last updated: August 17, 2026
Sipster is local-first: what you drink is recorded on your phone and stays there. This policy explains the small number of things that do leave your device, and why.
The short version
- Everything you log — drinks, goals, streaks, history — is stored on your device.
- No account is required for anything, including buying Pro and using support.
- What leaves the device: anonymous usage telemetry, anything you deliberately send us (feedback), and the data Google AdMob needs to show ads in the free version.
- Your intake is never sold, never shared with advertisers, and never used to target ads.
- Delete the app and the data goes with it. Export it first if you want to keep it.
Who we are
Sipster ("the app") is provided by JUNAID MOHAMMED ABDUL NAYEEM ("we", "us"), based
in Chicago, Illinois, USA. You can reach us any time at
junaid.mohammed777@yahoo.com. The Android package
name is com.watertrackerlife.water_tracker.
What is stored on your device
Your logged drinks, daily goal, cup sizes, custom drink types, reminder times, streaks, challenge progress, themes and app settings are held in a private database on your phone that only Sipster can read. This is the primary copy of your data, and at present it is the only copy: Sipster does not upload your intake history to us or to anyone else. Logging works identically with no network connection.
Anonymous usage telemetry
So we can tell whether the app is working and which screens people actually use, Sipster sends a small stream of events — names like "app opened" or "drink logged" — tagged with a randomly generated install code. That code identifies the installation, not you: it is not your name, your email, your phone number, your advertising ID or your device's serial number, and it is regenerated if you reinstall.
The amounts you log are not included. Nobody, including us, can see what or how much you drank.
Signing in — optional, and for two things only
Sipster never asks you to create an account, and every feature works signed out. If you choose to sign in with Apple (on iOS) or Google (on Android), through Firebase Authentication, we receive your email address and display name, and we use them for exactly two purposes:
- your Pro purchase follows your account rather than that one installation, so a new phone recognises it; and
- your support conversation follows you, so a reply is not lost when you change device.
That is all. Signing in does not upload your drink history, and there is no cloud copy of your logs. If you never sign in, we hold no email address for you at all.
Support messages and feedback
If you write to us from inside the app, we receive your message, the email address you provide, and a phone number only if you choose to add one — attached to the same random install code and to nothing else, so that a person can reply to you. If notifications are enabled, a push token is stored so the reply can reach your phone.
Advertising in the free version
The free version is supported by advertising served by Google AdMob. To select, cap and measure those ads, AdMob may collect your device's advertising identifier, IP address, coarse location derived from that IP address, device information and ad-interaction data. Google's handling of it is governed by Google's privacy policy.
What you drink is never shared with any advertising provider and is never used to target advertising. Sipster does not ask for permission to track you across other companies' apps and websites. A Sipster Pro subscription removes advertising entirely.
Beyond AdMob and the anonymous telemetry described above, Sipster contains no third-party analytics or tracking SDKs.
Purchases
Pro subscriptions are sold and billed by Apple (App Store) or Google (Google Play). We never see or store your card details. A purchase receipt is validated with the store so the app knows your subscription is active, and we keep a record of that entitlement — the product, the status and the dates — against your install code or, if you signed in, your account.
Notifications
Reminders are scheduled locally on your device by the app itself; we do not need to reach your phone to deliver them. Push notifications from our side are used only to tell you that we have replied to your support message.
Health and fitness data
This version of Sipster does not read from or write to Apple Health or Health Connect, and requests no health permissions. If that ever changes, this policy will be updated before the feature ships, and the app will ask for your permission first.
Children
Sipster is not directed to children under the age at which local law allows them to consent to data processing, and we do not knowingly collect personal information from children. If you believe a child has provided us information, write to us and we will remove it.
Security
Data in transit is encrypted. Data on your device is protected by your device's own security, which is a good reason to have a passcode. No method of storage or transmission is perfectly secure, and we cannot promise absolute security.
Your choices and your rights
- Export everything as CSV from inside the app (Pro).
- Delete your device data by uninstalling the app; delete your account and everything held server-side as described on the data deletion page.
- Turn off ads by subscribing to Pro.
- Grant or revoke notification permission at any time in your device settings.
- Depending on where you live — including under the GDPR and the CCPA — you may have rights of access, correction, deletion, portability and objection over the limited data we hold. Email us and we will act on it.
We do not sell personal information, and we do not share it for cross-context behavioural advertising.
Changes to this policy
We may update this policy from time to time. Changes take effect when the updated policy is posted here with a new date. Material changes will be described in the app.
