Polyglot AI is built with a privacy-first philosophy. We do not create accounts, do not sell your data, and do not store your translation history on any server. Everything you translate stays on your device — except the text sent to our translation API in the moment of processing.
No server-side storage
No user accounts
No ads or tracking
History stored on-device only
Polyglot AI ("we", "our", or "us") is the developer of the Polyglot AI iOS application ("App"). If you have questions about this policy, contact us at:

App Store: Use the "App Support" link on the Polyglot AI App Store page.
When you type or paste text into the translation field, that text is transmitted to our cloud translation API to produce a result. The text is used solely to fulfill your translation request. We do not log, store, or retain this content on our servers after the response is delivered.
When you use the microphone button, Apple's on-device Speech Recognition framework converts your speech to text locally on your device. The resulting text string is then handled the same way as typed text (see 2.1). Audio recordings are never uploaded to our servers.
When you point the camera at text or select a photo from your library, Apple's Vision framework extracts the text locally on your device using on-device machine learning. No image or photo is ever sent to our servers. Only the extracted text string is processed for translation (see 2.1).
All translation history, saved phrases, and favorites are stored exclusively on your device using Apple's SwiftData framework. This data is never synchronized to our servers. You can delete all history at any time from the History tab > Clear All.
Your chosen native language, target language, and use case (Education, Travel, Research, or Business) are stored locally in iOS UserDefaults. This data never leaves your device.
If you enable the optional "Quick Translate" feature, the App may read the current clipboard contents when you return to the App to offer a one-tap translation suggestion. Clipboard content is processed identically to typed text and is never stored.
No name, email address, or contact information
No Apple ID or social sign-in data
No device identifiers (IDFA, IDFV)
No location data
No analytics or crash-reporting telemetry (in this version)
No payment information (there are no in-app purchases in v1.0)
Text translation is powered by a large language model (GPT-4o-mini) hosted on Replicate's infrastructure. When you trigger a translation, the source text and target language code are sent over HTTPS to Replicate's API. Replicate processes the request and returns the translated text.
We do not store query content on our side. Under our data privacy usage, data submitted to the API is processed strictly to generate translations and is not used to train the underlying AI models. Replicate's and OpenAI's own privacy terms govern their technical handling of API requests.

The App utilizes several native iOS frameworks to ensure maximum on-device processing and security. All of these operate locally under Apple's standard privacy practices:
Speech (SFSpeechRecognizer): Used for voice-to-text conversion. This process runs entirely on-device.
Vision Framework: Used for OCR text extraction from your camera or photo library. It relies purely on local machine learning and never uploads your images.
AVSpeechSynthesizer: Used for on-device text-to-speech voice playback.
SwiftData: Used to securely store your local translation history and favorites on your device.
WidgetKit: Used to display your daily phrases on the iOS Home Screen via a localized App Group.
App Intents / Siri: Used to support Siri Shortcuts integration, operating under Apple's system-level policies.
The only personal information we process is the text you submit for translation. We use it solely to:
Deliver the translated result to you in the App.
Generate daily phrase suggestions tailored to your chosen learning domain.
We do not use your data for advertising, profiling, resale, or any purpose beyond providing the translation service you requested.
Translation requests are sent to the API and the response is returned to you. We retain no server-side logs of your translation queries. All user-generated content (history, favorites, preferences) lives entirely on your device and persists until you delete it or uninstall the App.
All communication between the App and the translation API is encrypted using TLS 1.2 or higher (HTTPS). Any API credentials stored in the App are protected using iOS Keychain Services. We follow Apple's App Transport Security (ATS) requirements. No sensitive data is stored in cleartext on your device.
Because we do not maintain a user account or server-side database linked to you, most data subject rights are exercised directly on your device:
Delete translation history: History tab > Clear All
Delete saved phrases: Phrasebook tab > swipe to delete
Reset all preferences: Delete and reinstall the App
Revoke camera permission: iOS Settings > Polyglot AI > Camera > Off
Revoke microphone: iOS Settings > Polyglot AI > Microphone > Off
Revoke photo library: iOS Settings > Polyglot AI > Photos > Off
Revoke speech recognition: iOS Settings > Polyglot AI > Speech Recog. > Off
If you are a resident of the European Economic Area (EEA), United Kingdom, or California (CCPA), you have additional rights. Please contact us at bang77bang88@gmail.com to exercise those rights.
Polyglot AI is not directed to children under the age of 13 (or 16 in the EEA). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.
When you use the cloud translation feature, your text is sent to Replicate's servers, which may be located in the United States or other countries. By using the App, you acknowledge that your data may be transferred to and processed in countries with different data protection laws than your own. We rely on Replicate's standard contractual commitments for such transfers.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this document. Continued use of the App after changes are posted constitutes acceptance of the updated policy. For significant changes, we will display an in-app notice.
