Privacy Policy
Last updated November 8, 2026. Water on Track is in development; we will update this policy before launch if anything below changes.
This policy covers the iPhone and Android apps. Where a section mentions your iPhone, Apple Health, Sign in with Apple or Apple purchases, it describes the iPhone app; the Android app is described in its Android sections.
This policy explains how Water on Track (the iPhone and Android apps and waterontrack.com) handles information. The app is operated by Solstice Labs LLC, a Colorado limited liability company, 215 S Wadsworth Blvd Ste 400, Lakewood, CO 80226 ("we").
Summary
Drink logs, targets and reminder hours are stored on your phone.
Important information
This is a personal log, not medical or nutrition advice. Talk to a clinician about fluid needs if you have a health condition.
Drink names and amounts stay on your iPhone and are not used for advertising.
Information we collect
- If you choose to create the optional account: your email address or Sign in with Apple identifier, and the name Apple shares if you allow it
- If you purchase the optional supporter subscription: purchase and subscription status
Information we do not collect
- Location, contacts, or an advertising identifier
- Tracking across other companies' apps
- Your drink names and amounts
Health information
Water on Track is a personal log, not medical or nutrition advice. It does not tell you how much you should drink.
Optional account
You can use every feature without an account. The Android app has no account. On iPhone, if you choose to sign up (with email or Sign in with Apple, 18 or older only), one account works in all of our apps. We store your email or Apple sign-in identifier, which of our apps you've signed in to, your marketing and beta choices in each app with the time you made them, and an optional backup of each app's settings and records. Health readings and photos are never included. If you have an ad-free subscription, we also store its end date and Apple's transaction identifier (checked against Apple's signature) with your account. You can sign out, turn choices off, or delete your account any time from Profile; deleting it removes it and its backups in all of our apps. See our suite account page for what the shared account stores and how to delete it.
If you sign in with a verified email address or Apple ID that also belongs to a NearbyGrid account, our accounts server checks whether that NearbyGrid account is in good standing and was active in the past 7 days. If it was, your Solstice Suite apps are ad-free until 7 days after that activity. The only result the check gives is whether you qualify and until when; that date is held briefly in the server's memory (up to 10 minutes), is not saved to your suite account, and no other NearbyGrid information is shared with the suite apps.
Our apps on your iPhone
To avoid promoting apps you already have, the app checks whether our other apps are installed on your iPhone. It can only check for our own apps, and the result stays on your device. If you buy an ad-free subscription, the app saves its end date in a place only our apps can read, so our other apps on the same iPhone can turn ads off too.
iOS permissions
- Notifications (optional) — For reminders you turn on.
- Apple Health (optional) — Only if you turn on sync. Your own logged drinks can be written, and existing Health water can be read. Nothing is invented.
Android and Health Connect
The Android app optionally reads and writes hydration records through Health Connect, and only after you allow access in the Health Connect permission screen. The records are handled on your phone; they are not uploaded and are not used for advertising. You can revoke access at any time in Health Connect; the app then stops reading and writing and continues to work with its own local log. The app works fully without Health Connect.
Android app: purchases, diagnostics and network
Purchases. The optional subscription is sold through Google Play. Google processes the payment; RevenueCat receives the purchase receipt and subscription status so the app can restore the supporter state on another install signed into the same Google Play account. The app creates no account, and RevenueCat's automatic device-identifier collection is disabled.
Crash and diagnostic reports. If the app crashes or reports a handled error, Sentry receives a report with the stack trace, app version, device model and Android version, plus a short diagnostic trail of screens, fixed action codes and network events (URLs without query strings). Sentry's automatic personal-data collection is off; the app never attaches a user identity, screenshots, view hierarchy, cookies or request headers, and there is no advertising identifier. It does not include your drink logs, targets or other app content.
Network. The app still works with no connection. A connection is used to load subscription products, validate or restore a purchase, and send crash and diagnostic reports (including Sentry sessions/performance).
Ads. This app shows no ads. The optional $19.99/year subscription supports the app; every feature is already free.
Service providers
We use a small number of providers only to run the app. They may not use your information for their own purposes.
- RevenueCat — Processing the optional supporter subscription and restoring purchases. It does not receive your app content.
- Sentry — crash and performance diagnostics via Sentry; no account, email or content
Advertising
Any ads in our apps promote only our own apps. We do not sell personal information, do not share it for cross-app advertising, and do not use Apple's advertising identifier to track you. The Android app has no advertising identifier.
Purchases
On iPhone, optional supporter subscriptions are processed by Apple. On Android, they are sold through Google Play. We receive purchase status (for example, whether a subscription is active) but never your payment card details.
This website
This website (waterontrack.com) uses Cloudflare Web Analytics to count page views. The counter sets no cookies, stores nothing on your device and does not build a profile of you across sites. Cloudflare hosts this website: it receives the page address, referring page and browser type of each visit to produce these counts, and it processes standard request logs to serve the pages. See Cloudflare's privacy policy. This website does not use Google Analytics or advertising cookies. What the app itself collects is described in the rest of this policy.
Children
The app is not directed to children under 13, and we do not knowingly collect their personal information.
Your choices and rights
You can use the app without an account, turn off notifications and permissions in iPhone Settings, and delete local data by deleting the app. To access or delete information connected to you, email privacy@solsticesuiteapps.com. Depending on where you live (for example, the EU, UK or California), you may have additional rights, and we will honor them.
Retention and security
We keep information only as long as needed for the purposes above and protect it with reasonable safeguards.
Changes
We will post changes here and update the date above.
