1. Ποιοι Είμαστε

Το TonesFly λειτουργεί από τον Thang Pham ("TonesFly", "εμείς", "μας"). Αυτή η Πολιτική Απορρήτου εξηγεί πώς συλλέγουμε, χρησιμοποιούμε και προστατεύουμε τις πληροφορίες σας όταν χρησιμοποιείτε την εφαρμογή TonesFly (η "Εφαρμογή").

Για τους σκοπούς του GDPR, ο Thang Pham είναι ο υπεύθυνος επεξεργασίας δεδομένων. Επικοινωνία: [email protected]

2. Πληροφορίες που Συλλέγουμε

We collect the following types of information:

Account information — your email address, display name, authentication provider, and account/user ID when you create or link an account via Apple Sign-In, Google Sign-In, or email
Audio files — audio files you import into the App for listening practice (processed and stored on-device only; never sent to any server)
Transcripts and lesson data — generated entirely on your device from your imported audio; stored on-device and in iCloud (if enabled) only
Learning data — practice progress, accuracy scores, challenge completion, and streaks stored locally on your device
Device-linked identifiers — a persistent device_id stored in Keychain and sent to our server for account binding and free-tier limit enforcement
Preferences — your native language, stored locally on your device
Device information — device model, operating system version, and app version for diagnostics
Usage analytics — product interaction data used to improve the App; optional analytics are collected only with your consent
Campaign attribution — when you open the App from a marketing link, we may collect anonymous UTM parameters (source, medium, campaign name) to measure marketing effectiveness. These parameters do not contain personally identifiable information and are processed through PostHog subject to your analytics consent

3. Νομική Βάση Επεξεργασίας (GDPR)

Έννομο συμφέρον (Αρθ. 6(1)(στ)) — Πληροφορίες συσκευής και ανωνυμοποιημένα αναλυτικά
Συγκατάθεση (Αρθ. 6(1)(α)) — Μη απαραίτητα αναλυτικά (PostHog), ανακλήσιμη ανά πάσα στιγμή

4. Πώς Χρησιμοποιούμε τις Πληροφορίες σας

We use the information we collect to:

Provide, maintain, and improve TonesFly
Process imported audio entirely on your device to generate listening practice challenges
Authenticate your account and manage subscriptions
Enforce the free tier fairly and prevent abuse across multiple accounts on the same device
Process subscriptions and in-app purchases
Send important service updates via email

5. Επεξεργασία Αρχείων Ήχου

Audio is processed entirely on your device and never leaves it.

When you import an audio file:

Speech recognition runs on your device using on-device models
All transcription, lesson generation, and practice content creation happen on your device
No audio, transcripts, or lesson content are sent to any server
Audio files are stored on-device and in iCloud (if enabled) only
Processed challenge data is stored locally on your device and in your iCloud account for offline practice

Automated processing: Speech recognition and challenge generation are fully automated and run entirely on your device. No human reviews your audio or transcripts.

5a. On-Device Processing

TonesFly uses on-device speech recognition to convert your imported audio into text for listening practice. All speech recognition and lesson generation run entirely on your device — no audio or transcript data is sent to any external service.

All lesson content is generated and stored on your device.

5b. Automated Processing (GDPR Art. 22)

TonesFly uses on-device automated processing to generate listening practice challenges from your audio. This includes speech recognition, challenge generation, and adaptive pacing. All of this processing runs entirely on your device.

These automated processes help create your learning content but do not produce legal effects. Under GDPR Article 22, you have the right to request human review of any automated processing decision that significantly affects you by contacting [email protected].

For users under the applicable age threshold (13–18 depending on region), optional data collection is disabled entirely.

6. Υπηρεσίες Τρίτων

We use the following third-party services to operate and improve the App:

RevenueCat — subscription and purchase management
PostHog — product analytics (consent-based)
Firebase — authentication and crash reporting
Cloudflare — cloud hosting and edge network services (Workers, D1, KV)
Resend — transactional email delivery

These providers process data under data processing agreements with appropriate safeguards. Our Data Processing Agreement is available at https://tonesfly.com/dpa. Apple handles all subscription billing directly.

7. Κοινοποίηση Δεδομένων

We do not sell, rent, or trade your personal data to third parties. This applies to all users, including California residents.

We may share data with:

Cloud hosting and infrastructure providers (for authentication and account management only)
Analytics services (product interaction data, with your consent where required)
Payment processors (Apple handles all subscription billing)
Legal authorities when required by law or to protect our legal rights

Audio, transcripts, and lesson content are processed entirely on your device and are not shared with any third party.

For California residents (CCPA/CPRA): We do not sell personal information. We do not share personal information for cross-context behavioral advertising. We do not collect or process sensitive personal information as defined by the CPRA, including precise geolocation, racial or ethnic origin, religious beliefs, genetic data, biometric information, or health information. You have the right to know what personal information we collect, request deletion, and opt out of any future sale. Contact [email protected] to exercise these rights.

8. Ασφάλεια Δεδομένων

We implement industry-standard security measures to protect your data, including encryption in transit (TLS/HTTPS). Our server infrastructure is hosted on Cloudflare's global network (Workers, D1, KV) and handles only authentication and subscription management. Audio, transcripts, and lesson content are processed and stored entirely on your device and in your iCloud account — they are never sent to our servers.

In the event of a data breach that poses a risk to your rights and freedoms, we will notify the relevant supervisory authority within 72 hours and affected users without undue delay, as required by GDPR Article 33-34.

However, no method of transmission over the internet is 100% secure.

9. Διατήρηση Δεδομένων

We retain your data for as long as your account is active or as needed to provide services.

Audio, transcripts, and lesson content: stored on-device and iCloud only. Never sent to our servers.
Account data (email, display name, device_id, subscription status): retained on our servers until account deletion.
Practice data: stored locally on your device; deleted when you remove the app, delete individual lessons, or choose to remove local data.
Analytics data: retained for up to 12 months, subject to your consent settings.

You may request account deletion at any time from Settings > Delete Account. When you request deletion, your account enters a 7-day grace period during which you may cancel by signing in. After the grace period expires, all your data is permanently deleted from our servers. We send email confirmation when deletion is scheduled, a reminder 24 hours before, and confirmation after deletion.

TonesFly cannot delete data stored in your iCloud account. To manage iCloud data, visit Settings > [Your Name] > iCloud on your device.
