DLV Digital Solutions Pty Ltd ("we", "our", "us") operates the Fluxa language learning application (the "App"). This Privacy Policy explains how we collect, use, store, and protect information when you use our App.
ABN: 71 697 056 590. Registered in Victoria, Australia.
By downloading and using Fluxa, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the App.
Fluxa is designed with a privacy-first approach. We do not ask you to create an account. We do not collect your name, email address, phone number, contacts, or location.
The following never leaves your device and is not transmitted to us:
When you use an AI-powered feature — the Sofia conversation partner, the Translate screen, or pronunciation guidance — the following is sent to our server:
We do not use any analytics, advertising, or crash-reporting service. Fluxa contains no third-party analytics SDK. We do not collect product interaction data, crash logs, performance data, advertising identifiers, or any tracking identifier, and we do not track you across apps or websites.
We do not sell your data. We do not use your data for advertising. We do not share your data with third parties except the service providers described in Section 4.
AI requests are sent to a server function we operate, hosted on Supabase in the Sydney, Australia region. This server applies fair-use limits and then forwards your text to Anthropic. It exists so that our AI credentials are never stored inside the App.
The AI features are powered by Anthropic's Claude models. Your practice text is forwarded to Anthropic to generate a response. No identifier of any kind is sent to Anthropic — not your device identifier, not an account, not any user reference. All requests reach Anthropic under our single organisational key, so Anthropic cannot distinguish or link the requests of one Fluxa user from another. Anthropic's handling of this data is governed by their privacy policy at anthropic.com.
Fluxa uses Firebase App Check to confirm that AI requests come from a genuine, unmodified copy of the App. This involves Apple's App Attest / DeviceCheck service on iOS and Google Play Integrity on Android, which produce a short-lived attestation token. This process runs periodically in the background. No practice text, learning data, or Fluxa device identifier is sent to Google or Apple through this mechanism.
In-app purchases are processed entirely by Apple or Google. We receive confirmation that a purchase occurred but never see or store your payment details. Their respective privacy policies govern how they handle payment data.
Your learning data stays on your device. Progress, history, settings, purchases, and your phrasebook are stored locally using your device's app storage. Uninstalling the App permanently deletes it.
Your conversations and translations are not stored on our servers. The text you send passes through our server in memory to generate a response and is then discarded. We do not keep a copy of your messages, translations, or Sofia's replies.
We keep a technical usage record. For each AI request we store only: the random device identifier, which feature was used, the timestamp, the AI model used, the number of text units processed, and the resulting cost. This record contains no message content. We retain it for 90 days and then delete it.
Our hosting provider also keeps short-term operational logs of server activity in the ordinary course of running the service. These are retained for a limited period according to their platform policy and contain no message content.
Language pack purchases (US$4.99 each) are processed entirely by the Apple App Store or Google Play. We never see, collect, or store your credit card or payment details. Records of what you have purchased are stored on your device. All purchases are one-time and non-consumable; we do not operate subscription billing.
Fluxa may ask permission to send you a daily Word of the Day notification. This is entirely optional. These notifications are scheduled and generated on your device from content included in the App — they are not sent from our servers, we do not use a push notification service, and no push token is created or transmitted. We have no way of knowing whether or when a notification was delivered. You can disable notifications at any time in the Fluxa Settings screen or your device settings. We do not send marketing notifications.
Fluxa is intended for users aged 13 and over. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us at privacy@fluxa.com.au and we will delete it promptly.
Under the Australian Privacy Act 1988 and applicable law, you have the right to:
Because we do not hold accounts or identifying information, most of your data is under your own control: uninstalling the App deletes everything stored locally, including the device identifier. To make a request concerning our technical usage records, contact us at privacy@fluxa.com.au.
We take reasonable steps to protect information processed through our services. All communication between the App and our servers uses HTTPS encryption, our AI credentials are held server-side and never included in the App, and AI requests are verified using device attestation. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
For any privacy-related questions or requests:
We may update this Privacy Policy from time to time. Material changes will be notified through the App. The date at the top of this page reflects when the policy was last revised. Continued use of the App after changes constitutes acceptance of the updated policy.
