AquaLog privacy policy

In short

AquaLog is an aquarium tracker for water readings, tank inhabitants and care reminders. You can use it without an account. Your records are stored on your device. The free version shows ads from Google AdMob; Premium removes them. We do not sell data.

Who we are

AquaLog is published by ONOUR IMPRAM VENTURES LTD, a company registered in the United Kingdom under company number 17429906, which is responsible for the personal data described here. Contact: onour@onourimpram.com.

Data that stays on your device

The following is stored only in the app’s storage on your device and is not sent to us:

• Your aquariums: name, volume, type and notes
• Water test readings: pH, ammonia, nitrite, nitrate, temperature and salinity, with the date and a note
• The inhabitants you record: name, species, count, type, the date added and a note
• The reminders you set, and any custom trackers you create, with their entries (date, value and note)
• Language, theme and notification settings

Service providers

• Google AdMob shows ads in the free version. The data it processes is described under Advertising below.
• RevenueCat handles receipt validation when you upgrade to Premium. It receives a random anonymous identifier generated for each install, your Google Play transaction receipt and your country, derived from the store you bought through. It does not receive your name or email address. Your aquarium records are never sent to RevenueCat.
• Google Play processes the purchase itself under your Google account.
• Sentry receives crash reports from the app, in its EU (Frankfurt) region. A report carries a stack trace, anonymous breadcrumbs of the screens you opened and the buttons you tapped in the last sixty seconds, the device model, the Android and app versions, and a random install ID that resets when you reinstall. The app does not send your name, email address, location or anything you typed. Reports are deleted after ninety days. Free text is removed from the breadcrumbs before a report leaves the device.
• Links you open are handed to your browser and that site's own privacy practices apply.

Advertising

The free version of AquaLog shows ads from Google AdMob.

Premium removes the ads.

To show, measure and limit ads and to prevent fraud, the Google Mobile Ads SDK collects the following and shares it with Google: your device’s advertising ID; your IP address, from which Google derives an approximate location; device and app information such as model, operating system, language and app version; diagnostic data such as crash and performance logs; and which ads you were shown and whether you tapped them. Google uses this data for advertising, analytics and fraud prevention under its own privacy policy.

If you are in the European Economic Area, the United Kingdom or Switzerland, the app first shows Google’s consent form (User Messaging Platform) and requests ads only when Google’s consent status allows it. If you do not agree to personalised ads, Google can still show non personalised ads, which use the same technical data for delivery, frequency limits, reporting and fraud prevention but are not based on your past activity. Outside these regions ads may be personalised. To change or withdraw your consent, email us; you can reset or delete your advertising ID in Android settings. You can review or change your choice later from the privacy options in the app.

Your aquariums, water readings, inhabitants, notes and reminders are never sent to AdMob or to any advertiser.

What we do not do

• Your records are not uploaded, and we run no server that stores your personal data.
• No account is required.
• The app does not collect precise location, your contacts, call or SMS history, health or fitness data, biometric data or microphone audio.
• There is no usage analytics service in the app. Crash reports, described above, are the only diagnostics it sends besides the advertising data described above.
• No data sale, and no sharing with advertising data brokers.

Permissions

• Internet and network state (INTERNET, ACCESS_NETWORK_STATE), used for ads, Premium purchases and crash reports.
• Advertising ID (AD_ID) and ad services (ACCESS_ADSERVICES_AD_ID, ACCESS_ADSERVICES_ATTRIBUTION, ACCESS_ADSERVICES_TOPICS), declared by Google's Mobile Ads SDK and used by Google AdMob as described above. You can reset or delete your advertising ID in Android settings.
• Google Play billing (BILLING), used when you buy or restore Premium.
• Notifications (POST_NOTIFICATIONS), for the reminders you set in the app. Android asks you before the app can show a notification, and you can turn notifications off for the app in Android settings.
• Vibration (VIBRATE), declared by the haptics and notifications libraries the app includes.
• Wake lock (WAKE_LOCK) and foreground service (FOREGROUND_SERVICE), declared by libraries the app includes. Neither gives the app access to your personal data.
• Storage (READ_EXTERNAL_STORAGE on Android 12L and older, and WRITE_EXTERNAL_STORAGE), declared by the document picker, file system and sharing libraries the app includes, for files you choose to import, export or share.
• Display over other apps (SYSTEM_ALERT_WINDOW), declared in the app's manifest. Android grants it only if you switch it on yourself in system settings.
• Launcher badge permissions (READ_APP_BADGE and the badge permissions of several device makers' launchers), declared by the notifications library for app icon badges. They give the app no access to your data.
• Other manifest permissions (the Google install referrer service, the cloud messaging receive permission and DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION, an app-specific permission that keeps the app's own broadcast receivers private) are declared by libraries the app includes. The released build contains no Firebase project configuration.

Your choices and deletion

Your records are stored on your device. Uninstalling the app deletes them, unless you used your phone's own backup feature, which is outside our control. You can stop crash reports with Diagnostics opt-out in Settings, where available. If you use a share or export feature, the content goes to the app you choose in Android's share sheet and that app's own rules apply from then on. Purchase records stay with Google Play and RevenueCat, and crash reports stay with Sentry for ninety days; to ask about those records, email us with the purchase's transaction ID or the time of the crash and your phone model. We respond within thirty days.

Your rights

Depending on where you live, you may have rights to access, correct, delete or object to the processing of your personal data. Send requests by email; we will not ask for more information than we need to respond. In the United Kingdom you can also complain to the Information Commissioner’s Office.

Children

AquaLog is not directed to children under 13 and does not knowingly collect personal data from them.

Changes

We update this policy before any change to the app’s data practices is released. The effective date is shown at the top of this page.
