Stop guessing.
Start keeping.
Aqua Flux keeps every tank you own organized in one place — exact volume instead of a rough guess, fish compatibility before you buy, and water tests logged the way you'd actually run them: drop by drop.
Everything a tank needs to be understood, not just maintained.
Exact volume, every shape
Add each aquarium once — its shape, its size, whatever glass or acrylic box you've got — and get a precise liter count instead of a napkin-math guess.
Compatibility at a glance
Thinking about a new fish? Pull up its profile and see whether temperature range, water chemistry, and temperament line up with your current residents.
Drop-by-drop testing
Add reagent, count the drops, match the color yourself — the way you would at the tank. Every reading is saved automatically, no extra step required.
The cycle, visualized
Watch ammonia and nitrite settle and nitrate creep up over weeks. Look back anytime to see how a tank has changed since day one.
How much water are you really keeping?
Enter your tank's inside dimensions in centimeters. We'll do the math the same way Aqua Flux does the moment you add an aquarium.
Built by people who forgot a water change too, once.
We're a small team of aquarium keepers who got tired of relying on memory, sticky notes, and hopeful guessing for things that deserve better tracking. Aqua Flux started as a tool we needed ourselves before it became one we wanted to share.
Our mission is simple: give every fishkeeper — from someone cycling their very first ten-gallon setup to a hobbyist juggling a whole fishroom — a clear, honest picture of what's actually happening in their water, without turning care into a chore.
Aqua Flux turns rough guesses into exact numbers. Add a tank and get its real volume. Check a new fish against your current residents before checkout. Test your water drop by drop and watch the readings quietly build into a history you can actually learn from.
Know your water. Trust your tank.
Your tank data stays in your tank room — not ours.
1. Information We Collect
Aqua Flux does not collect any personal information, account details, or usage data. There is no sign-up, no login, and nothing you type — tank dimensions, fish profiles, or drop-test readings — is ever transmitted off your device.
2. How We Use Information
Because nothing is collected, nothing is analyzed, aggregated, sold, or shared. We don't build usage profiles, we don't track how you use the app, and we have no advertising or data-monetization model of any kind.
3. Data Storage
Every aquarium you add, every fish profile you save, and every water test reading you log is stored exclusively on your own device. Aqua Flux has no cloud backend, no remote database, and no server that your data ever touches.
4. Third-Party Services
The app does not integrate third-party analytics, advertising networks, or tracking software of any kind. There are no external SDKs quietly watching how you use your tank log.
5. Data Security
Since your tank records, water chemistry history, and fish compatibility notes never leave your device, there is no transmission to intercept and no remote server to breach. Your information is as secure as your device itself.
6. Children's Privacy
Aqua Flux does not knowingly or unknowingly collect information from anyone, including children under 13. With no accounts, no forms, and no data transmission, there is nothing to collect regardless of who is using the app.
7. Your Control
There are no accounts to manage because there is nothing stored anywhere but your phone. If you'd like to remove your tank history, fish profiles, or test logs entirely, simply delete the app — everything goes with it.
8. Changes to This Policy
If this policy is ever updated, the revised version will be published within the app along with a new effective date. Continued use of Aqua Flux after changes take effect means you accept the updated terms.
