Privacy Policy
Blue Balance — hydration tracking
Effective: August 1, 2026 · Last updated: August 1, 2026
Blue Balance (“the app”, “we”, “us”) is a hydration tracking app published by Fluxtent Portfolio. This policy explains what the app collects, why, who it is shared with, and how to delete it.
We do not sell your personal information. The app contains no advertising, analytics, or tracking SDKs of any kind, and does not track you across other companies’ apps or websites.
1. Information we collect
We only collect what the app needs to work. Everything below is tied to your account.
Account information
| Data | Why |
|---|---|
| Email address | Identifies your account; used for sign-in and password reset |
| Password | Verifies it is you. Stored only as a scrypt hash — we never store, see, or have any way to recover your actual password |
Profile information
You enter this, and most of it is optional: display name, first and last name, age, height, weight, activity level, wake and sleep times, unit preference, daily hydration goal, reminder interval, quiet hours, and appearance settings such as theme and accent color.
Height, weight, age, and activity level are used only to calculate your recommended daily water intake. You can leave them blank and set your goal manually.
Hydration data
Each drink you log: the amount, drink type, category, how it was logged, and the timestamp. Also any custom beverages you create, including name, serving size, and hydration factor.
Barcode data
Only if you use barcode scanning. We store the barcode number of a product you scan, plus the product name and serving size returned by the lookup, so you do not have to re-scan the same item.
Camera images are never stored and never leave your device. The camera reads a barcode on-device, and only the resulting number is sent for lookup.
AI coach conversations
Only if you use the in-app coach. We store the messages you send and the replies you receive, so your conversation history is there when you return.
Subscription data
Only if you purchase a subscription. We store your subscription status, plan, renewal date, a billing customer identifier, and a count of scans used in the current period to apply plan limits.
We never receive or store your card number. Payment details go directly to the payment processor.
Technical data
Your IP address is processed transiently by our server to apply rate limits that protect against abuse. It is not written to your profile or used to build a record about you.
2. What we do not collect
To be explicit, Blue Balance does not collect, access, or transmit:
- Your location, at any precision
- Your contacts, photo library, calendar, or microphone
- Health records from Apple Health — the app does not integrate with HealthKit
- Any advertising identifier (IDFA); the app never asks for tracking permission
- Any behavioral or analytics telemetry — there is no analytics SDK in the app
3. How we use your information
Solely to provide the app:
- Create and secure your account, and keep you signed in
- Calculate your hydration goal and show progress, history, and streaks
- Save your logs, custom beverages, and preferences so they follow you across devices
- Send a password reset email when you request one
- Answer your questions if you use the AI coach
- Apply subscription entitlements and plan limits
- Prevent abuse of our servers through rate limiting
We do not use your information for advertising, profiling, or automated decisions that produce legal or similarly significant effects.
4. Who we share information with
We share data only with service providers that make the app function, and only the minimum each one needs. We do not sell data to anyone.
| Provider | What it receives | Why |
|---|---|---|
| Our cloud hosting provider | App data, as our host and database provider | Runs our server and stores your account |
| Stripe | Email and subscription details | Processes payments. Card details go directly to Stripe; we never see them |
| Resend | Your email address | Delivers password reset emails |
| Open Food Facts, UPCItemDB, Go-UPC | A barcode number only | Looks up product information. No account data or identifier is sent |
| Our AI provider | Your coach message and relevant hydration context | Generates coach replies. Not used to train third-party models |
We may also disclose information if required by law, or to protect the rights, safety, or property of our users or ourselves.
5. Data retention and deletion
We keep your data for as long as your account exists.
You can delete your account at any time from inside the app: Settings → Delete Account.
Deleting your account permanently removes your profile, every water log, your custom and scanned beverages, your coach conversations, your subscription records, and all active sessions. Any active subscription is cancelled at the same time. This is immediate and cannot be undone.
Backups are purged on our hosting provider’s normal rotation, typically within 30 days.
6. Security
- Passwords are hashed with scrypt and are never stored in a recoverable form.
- Session tokens are stored only as a SHA-256 hash, and refresh tokens rotate on every use, so a database leak cannot hand out live sessions.
- All traffic between the app and our servers uses HTTPS/TLS.
- Credentials on your device are held in the iOS Keychain, protected by the operating system.
- Every request is checked against the owner of the record, so one account cannot read or modify another’s data.
No system is perfectly secure, but we design on the assumption that any single layer can fail.
7. Your rights
Depending on where you live, you may have the right to access, correct, export, or delete your personal information, to object to or restrict processing, and to withdraw consent.
Most of these are available immediately in the app: view and edit your profile in Settings, or remove everything with Delete Account. For anything else, contact us and we will respond within 30 days.
California residents (CCPA/CPRA): we do not sell or share personal information as those terms are defined, and have not done so in the preceding 12 months. You will never be discriminated against for exercising your rights.
EEA and UK residents (GDPR): our lawful basis is performance of a contract (providing the app you asked for) and our legitimate interest in keeping the service secure. You have the right to lodge a complaint with your local data protection authority.
8. Children
Blue Balance is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.
9. Health disclaimer
Blue Balance is a general wellness and habit-tracking app. It is not a medical device, and it does not diagnose, treat, cure, or prevent any condition. Hydration goals are general estimates based on the information you enter, not medical advice. Any guidance from the AI coach is informational only and may be inaccurate.
Always consult a qualified healthcare professional about your health, especially if you have a kidney, heart, or electrolyte condition, or are pregnant.
10. International transfers
Our servers are located in the United States. If you use the app from elsewhere, your information is transferred to and processed there, under appropriate safeguards for such transfers.
11. Changes to this policy
If we make a material change, we will update the date at the top and, where required, notify you in the app. Continuing to use Blue Balance after a change means you accept the updated policy.
