Your records, on your own phone.

01Information in your diary

FluidTracker lets you enter fluid intake, urine output, optional weight, blood pressure, pulse, temperature and blood glucose (where supported by your app version), notes, dates, times, units and diary preferences.

This information is stored in the app’s private storage on your device. The app works without an account. The iPhone and Google Play versions work offline without activation checks or an app expiry date.

The iOS widget receives only your selected display language, not diary records or notes.

FluidTracker does not automatically send your diary to us, sell your personal information, use diary information for advertising. It uses your device’s language, region, date, time and timezone settings. It does not request precise location.

02Advertisements and privacy choices

From version 1.3.0, FluidTracker shows small Google AdMob banners on browsing pages. Today and entry or correction forms stay free of ads. Ad requests are non-personalised. Readings, diary dates, notes, reports, backups and tracking preferences are not sent to Google or used to target ads.

Google’s advertising SDK may receive your IP address, approximate location, app or device identifiers, ad views and interactions, crash logs and performance information.

Google uses this information to deliver and measure ads, prevent fraud and improve its services. Non-personalised ads can still use device storage and identifiers for these purposes.

Android advertising ID

FluidTracker does not request precise-location access. The Android app includes advertising-ID permission for Google’s advertising SDK. When available, the SDK may use this identifier to deliver and measure ads and prevent fraud.

Your privacy choices

Where required, Google’s consent form asks for your privacy choices before ads can be requested. You can reopen the form using Ad privacy choices in Settings when this option is available. If consent or ads are unavailable, the diary remains usable.

Google handles advertising information under its own privacy policy. You can also read about its use of information from apps.

03Reports and backups you choose to share

You can export a report or backup. These files may contain health details and notes. You choose where to save or send them; FluidTracker does not receive a copy. A recipient or storage provider handles its own copy under its own privacy practices.

Standard backup files have no extra FluidTracker password. Save them somewhere you trust. FluidTracker does not automatically back up your diary to the cloud. To recover it after losing your phone, save a manual backup somewhere you can access from another device. Files you export manually remain wherever you choose to save them.

04Retention and deletion

Your diary stays on your device until you delete records or remove the app and its local data. Restoring a backup keeps a local recovery copy of the previous diary. Deleting a record from the active diary does not erase an earlier recovery copy or an exported file.

We cannot view, recover or delete a diary that never leaves your device. To remove all local FluidTracker copies, remove the app and its data. Delete exported files separately in the app or service where you saved them.

05Support messages and other services

If you email support, we receive the address, message and attachments you choose to send. Cloudflare Email Routing forwards messages sent to [email protected] to our support Gmail inbox. We use them to answer your request, not for advertising.

We delete support emails and attachments within 90 days after resolving the request, unless a legal obligation requires us to keep them longer. You can request access, correction or deletion through that address, subject to any legal retention duties. Please leave out diary files or medical details unless they are needed for your request.

Apple, Google, your device and any storage provider you choose may handle store, device-transfer, diagnostic or exported-file information under their own terms and settings. FluidTracker is intended for adults and caregivers, not children.

06Security and changes

FluidTracker relies on your device operating system’s app protection. Protect access to your phone and exported files. No storage method is completely secure.

We will update this policy if our data practices materially change. Questions about privacy? Contact [email protected].
