Privacy Policy

Voxolo ("Voxolo," "we," "us," or "our") makes a mobile app that helps people learn to speak a new language before a trip. This policy explains what information we collect, how we use it, and the choices you have. We wrote it in plain language on purpose — if anything is unclear, email us at hello@voxolo.app.

1. Information We Collect

Information you provide

When you set up Voxolo, you tell it things like your name, destination, trip date, current language level, daily practice time, and interests. This is used to build your personalized learning plan and is stored locally on your device, not on our servers.

Voice and speech data

Voxolo's core feature is spoken conversation practice. When you use the microphone, your speech is processed in order to: (a) convert what you say into text, and (b) generate the AI tutor's spoken and written replies. This processing is done using Apple's on-device Speech framework and/or our AI service provider (OpenAI), depending on the feature. We do not use your voice recordings to build a personal voice profile, and we do not sell voice data.

Learning & progress data

Your streaks, completed lessons, scores, and review history are stored locally on your device using Apple's on-device storage (SwiftData). This data is not transmitted to us except where needed to power a specific feature, such as sending your current level and interests to our AI tutor so it can tailor a conversation to you.

Purchases

Subscriptions are handled entirely by Apple through StoreKit. We never see or store your payment card details. Apple sends us signed purchase lifecycle information — such as the product purchased, expiry, renewal, or refund — together with the app's random installation identifier so we can unlock or remove premium access correctly.

Automatically collected information

Like most apps, our backend infrastructure providers may automatically log standard technical information (such as request timestamps and error logs) to keep the service running reliably and securely.

Website analytics

This website uses Plausible Analytics to understand which pages people find useful. Plausible is privacy-focused and does not use cookies or collect personal or identifiable data. Nothing it records can be used to identify you or to follow you across other websites, which is why this site shows no cookie consent banner.

What is measured is aggregate and anonymous: page views, the country your visit came from (derived from your IP address, which is never stored), the type of device and browser, the referring site, and any campaign tag in the link you arrived through. We also record two anonymous, aggregate counts — when someone joins the email list, and when someone clicks through to the App Store — so we can tell which pages are doing their job. These counts contain no email address and no personal data.

Plausible is EU-based, and the data it collects for this site is processed and stored within the EU.

To avoid treating a return visit as unrelated, this site stores anonymous campaign labels, the landing-page path, and the time of the visit in your browser for up to seven days. This contains no name, email address, device identifier, or full referring URL. Global Privacy Control or Do Not Track disables this local storage. If you sign up for our email list, those campaign labels are stored with your signup so we know which of our own pages or ads brought you. See Email list below.

App analytics

The app records a small set of product milestones — first open, onboarding completion, first lesson start and completion, paywall view, and purchase outcome — so we can understand where the experience is helping or failing. These first-party events use a random installation identifier stored on your device. They do not contain your name, exact trip date, advertising identifier, voice, conversation text, or lesson content.

If you allow tracking through Apple's permission prompt, the Meta SDK sends app install and session activity to Meta. We also send a smaller set of milestones so we can measure and improve ads for Voxolo: onboarding completion, first lesson completion, paywall view, trial start, and a verified paid purchase with its amount and currency. The SDK may collect device information as described in its privacy policy. We do not send Meta your name, trip details, voice, conversation text, lesson content, or our installation identifier. If you decline, the app does not initialize the Meta SDK or send these app events to Meta. If you later revoke permission, the app stops sending new Meta app events. Apple may still provide privacy-preserving, aggregate ad attribution without identifying you to us or the ad network.

Email list

If you enter your email address to hear about the app or receive travel tips, we store that address together with the languages and topics you selected, the page you signed up from, and any campaign tag as described above. Signups are handled by Netlify Forms. We use this only to send the emails you asked for, every one of which has an unsubscribe link. We do not sell or rent this list.

2. How We Use Information

• To build and adjust your personalized learning plan
• To power live AI conversation practice, pronunciation feedback, and text-to-speech
• To operate, maintain, and improve the app
• If you allow tracking, to measure and improve advertising for the app
• To respond to your support requests and feedback

We do not sell your information.

3. Third-Party Service Providers

To deliver Voxolo's features, we share limited information with the following service providers, who process it on our behalf:

• OpenAI — processes conversation text and/or voice audio to generate the AI tutor's replies, feedback, and spoken voice responses. See OpenAI's Privacy Policy.
• Supabase — hosts the backend infrastructure that connects the app to OpenAI and stores the limited app analytics described above. See Supabase's Privacy Policy.
• Apple — provides on-device speech recognition, app distribution, and subscription billing (StoreKit). See Apple's Privacy Policy.
• Meta — if you allow tracking, receives the limited app events described above to measure and optimize our app promotion ads. See Meta's Privacy Policy.
• Plausible Analytics — measures aggregate, anonymous website traffic. No cookies, no personal data, EU-hosted. Website only; it is not present in the app. See Plausible's Data Policy.
• Netlify — hosts this website and receives email-list signups submitted through it. See Netlify's Privacy Policy.

These providers may process information on servers located in the United States or other countries.

4. Data Storage & Retention

Most of your personal learning data (profile, plan, progress, streaks) lives locally on your device and is deleted automatically if you delete the app. Text and audio sent to our AI service providers during a conversation are used to generate a response and are not stored by us beyond what's needed to operate the feature; retention by our service providers is governed by their own policies linked above.

5. Children's Privacy

Voxolo is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us information, contact us and we'll delete it.

6. Your Choices

• You can deny microphone or speech-recognition permission, though this will limit speaking-practice features.
• You can deny or change app tracking permission at any time in iOS Settings. This does not limit speaking-practice features.
• You can delete all locally stored data by deleting the app from your device.
• You can email hello@voxolo.app with any privacy question or request.

7. Security

We use industry-standard measures (such as encrypted connections) to protect information in transit. No method of transmission or storage is 100% secure, and we can't guarantee absolute security.

8. Changes to This Policy

We may update this policy as Voxolo evolves. We'll update the "Effective" date above when we do. Continued use of the app after changes means you accept the updated policy.
