Nerite is an aquarium logbook. This policy explains exactly what the app collects, what it does not, and what you can do about it. It is written to be read, not to be survived.
Everything you record about your aquariums stays on your device. Tanks, water test results, dosing history, livestock, health observations, equipment, food and reminders are stored in a local database on your phone. We never receive them, and there is no account to create.
| Data | Why | Who receives it |
|---|---|---|
| Crash reports and diagnostics | To find and fix crashes | Google (Firebase Crashlytics) |
| Anonymous usage events — screens opened, features used | To understand which features are worth keeping | Google (Firebase Analytics) |
| A device notification token | Only if you enable notifications, so reminders and occasional tips can be delivered | Google (Firebase Cloud Messaging) |
| Purchase receipts | To verify a subscription or lifetime unlock and restore it on your other devices | Google Play or Apple, and our server |
An anonymous identifier is created so a purchase can be tied to a device without asking for your name or email. It is not linked to any real-world identity.
Nerite shows no ads, in either the free or the paid version. The app requests no advertising identifier — the Android permission that would allow it is removed from the build, not merely left unused — and there is no advertising consent form, because there is nothing to consent to.
If that ever changes, it will change in a release with a new version of this policy, and the consent form will appear before the first ad does.
Nerite is not directed at children under 13 and we do not knowingly collect data from them. Ads are limited to G-rated content.
Because your aquarium data never leaves your device, you control it directly:
We do not sell personal information, and we never have.
Diagnostic and analytics data is retained by Google for up to 14 months. Purchase receipts are retained for as long as you hold the entitlement plus the period required by tax law. Device notification tokens are deleted when you disable notifications or uninstall.
If this policy changes materially we will update the date at the top and, where the change affects what is collected, tell you inside the app before it takes effect.
