Privacy policy

01Who we are

"FluentCall" ("we," "us," "our") provides the FluentCall mobile application featuring our AI character "Cala." This Privacy Policy explains what information we collect, how we use it, who we share it with, and your rights. If you have questions, contact us at [email protected].

02Information we collect

Information you provide

• Onboarding answers. Your name (any name you type — there is no verified identity), target language, native language, level, why you're learning, and the time of day you'd like Cala to call. This is stored on your device.
• Voice and chat content. When you speak to Cala during a call or send a chat message, the audio or text is transmitted to our AI provider to generate Cala's response.

Information collected automatically

• Service-usage signals. Aggregate counts associated with an anonymous customer ID — total minutes of call time, number of chat messages, number of in-app extension purchases. We use this to detect abuse and to confirm our service is sized correctly. We do not log message content or audio content.
• Subscription state. Your subscription status (trial, active, lapsed) is managed by our subscription-management provider. We see only the state and the anonymous customer ID — not your name, email, or payment details.
• Crash and diagnostic data. If the app crashes, the operating system may send a crash report to us through Apple or Google, including device model, OS version, and the crash stack trace. No personal content is included.

Information from device permissions

• Microphone. Required for voice calls with Cala. The app uses the microphone only during an active call. We do not record or transmit audio when no call is in progress.
• Notifications. Optional. Used to remind you when Cala is calling. You can disable notifications at any time in your system settings.

03What we do not collect

To be specific about what does not happen:

• We do not collect your email address. We have no account system on our servers.
• We do not collect your real name. The name you type during onboarding is stored locally on your device only.
• We do not collect, store, or log your conversation audio after the call ends.
• We do not collect, store, or log the text of your chat messages on our servers.
• We do not collect contact-book, photos, location, calendar, or any health data.
• We do not sell your personal information. Ever.
• We do not run third-party advertising or tracking SDKs inside the app.

04How your conversations actually work

During a real call:

1. Your microphone audio is captured on your device and streamed in real time to Google's Gemini API via our backend.
2. Gemini generates Cala's voice response and streams it back to your device.
3. A text transcript of the conversation is generated for the on-screen captions and the post-call summary card.
4. When the call ends, the audio stream is closed. We do not retain the audio on our servers.
5. The conversation transcript and post-call summary are stored on your device, visible to you for the last seven days, and not visible to us.

For chat messages:

1. The message text you send is transmitted to our AI provider to generate Cala's response.
2. The message and Cala's reply are stored on your device, in your local chat history, for the last seven days.
3. We do not retain message content on our servers.

Google processes the data you send according to Google's Gemini API terms. Per those terms, paid Gemini API usage is not used to train Google's models.

05How we use information

We use the limited information described above to:

• Operate the Service — including transmitting your audio and messages to our AI provider so Cala can respond;
• Maintain your subscription status, including starting and ending free trials;
• Detect and prevent abuse, fraud, or excessive usage;
• Send you device notifications for scheduled calls (if you've enabled them);
• Improve the Service — for example, by spotting bugs from crash data;
• Comply with legal obligations.

06Third-party providers

We rely on a small set of providers. Each one is constrained to the specific purpose listed and bound by its own terms and privacy policies.

07Where your data lives

The default location for most of your data is your device. Specifically:

• Onboarding answers, name, target language, level, call schedule, vocabulary list — your device, in app storage.
• Last seven days of call summaries and chat messages — your device.
• Subscription state — your device (mirrored from RevenueCat for offline checks).
• Anonymous customer ID — your device's secure storage (iOS Keychain or Android Keystore).

Information on our servers is limited to anonymous usage counts and is stored at our cloud edge provider, located in regions that may include the United States, Canada, and the European Union.

08Retention

• On-device data. Your call summaries and chat threads are visible to you for the last seven days. Older summaries and threads are removed from view, though your vocabulary list and streak persist so Cala can continue to remember you. You can erase all on-device data at any time using "Delete my context" in Settings.
• Server-side usage counts. Aggregate usage counts associated with your anonymous customer ID are retained for up to 90 days, then rolled up to monthly aggregates. Monthly aggregates are retained for up to 24 months for service-sizing purposes.
• Voice and chat content. Not retained on our servers beyond the duration of the call or message.
• Subscription records. Retained by Apple, Google, and RevenueCat per their respective policies.

09Children

FluentCall is not directed at children under 16, and we do not knowingly collect personal information from them. If you believe a child under 16 has used the Service, please email [email protected] and we will take prompt steps to address it.

10International data transfers

Some of our providers process data in countries other than the country where you live, including the United States. Where required (for users in the European Economic Area, United Kingdom, or Switzerland), we rely on appropriate transfer mechanisms such as Standard Contractual Clauses with our providers.

11Your rights and choices

• Access and erase. Most of your data lives on your device. You can delete all of it at any time through Settings → "Delete my context." This clears your on-device state immediately.
• Delete account. Settings → "Delete my account" performs the on-device deletion and also rotates your anonymous customer ID so that any server-side usage history can no longer be associated with you. Subscription records held by Apple, Google, and RevenueCat are governed by their policies.
• Microphone. You can revoke microphone access at any time in your system settings. Without microphone access, you cannot make calls.
• Notifications. You can disable or re-enable notifications in your system settings or in the app's Settings tab.
• Marketing email. We do not currently send marketing email.

12If you're in California (CCPA / CPRA)

California residents have specific rights under the California Consumer Privacy Act, as amended by the California Privacy Rights Act, including the right to know, the right to delete, the right to correct, and the right to opt out of "selling" or "sharing" of personal information. We do not sell or share personal information as those terms are defined under the CCPA. To exercise your rights, contact us at [email protected].

13If you're in Europe or the UK (GDPR / UK GDPR)

If you are located in the European Economic Area, the United Kingdom, or Switzerland, the General Data Protection Regulation (or UK GDPR) applies. The lawful bases on which we process your data are:

• Performance of a contract — to provide the Service you have signed up for;
• Legitimate interests — to detect abuse, maintain security, and improve the Service;
• Consent — for optional features such as notifications.

You have the right to access, rectify, erase, restrict, or port your personal data, and to object to processing or withdraw consent at any time. You also have the right to lodge a complaint with your local data-protection authority.

14If you're in Canada (PIPEDA)

The Personal Information Protection and Electronic Documents Act (PIPEDA) applies to our handling of personal information of Canadian users. You have the right to access and request correction of your personal information, and to challenge our handling of it. To do so, contact us at [email protected].

15Security

We use reasonable technical and organizational measures to protect the limited information we hold. This includes TLS encryption in transit, secure storage of API credentials on the server side, and minimization of the data we collect. No system is 100% secure, however, and we cannot guarantee the security of information transmitted to or from the Service.

16This website (fluentcalls.com)

Our marketing website at fluentcalls.com is hosted by a third-party website builder. The website uses a minimal set of strictly necessary cookies provided by the host. We do not run third-party advertising, retargeting, or behavioral-tracking pixels on this site. The host may collect basic visit metrics (page views, country) in an aggregate, non-identifying form.

17Changes to this Policy

We may update this Policy from time to time. If we make a material change, we will provide reasonable notice through the Service or by updating the "Last updated" date at the top of this page. Continued use of the Service after the change takes effect constitutes acceptance of the updated Policy.

18Contact

If you have any question about this Policy or your data, please email [email protected]. We try to respond within five business days.
