Privacy Policy

This Privacy Policy applies to the Blendy Trips, Blendy Layers, and Blendy Translate apps and to any future mobile applications developed and published by Blendy Studio. If additional apps are released, they will follow the same privacy principles unless stated otherwise. Where an app works differently, its own section below says so. Blendy Translate has no account, no AI features, no advertising, and no purchases, so the sections on those topics do not apply to it.

Blendy Translate is a voice translator for blind and low-vision people. You speak, and the app translates and reads the translation aloud.

How your speech and text are handled:

• Microphone: the app asks for microphone access only to listen to you. It does not record or store audio.
• Speech recognition is performed by the speech recognition service installed on your device, which is a separate app, not Blendy Translate. Depending on your device and the language, that service may process audio on the device or send it to its provider, such as Google. This is governed by that provider’s privacy policy, and Blendy Studio does not receive the audio or the recognized text.
• Translation runs on your device using Google ML Kit models. Models are downloaded once per language, and no text is sent to us or to a translation server.
• Text-to-speech uses the speech engine installed on your device.
• Translation history and settings are stored on your device only. You can delete the history in the app, and uninstalling the app removes everything.
• Nearby devices (Bluetooth) permission is used only to listen through the microphone of a connected Bluetooth headset. The app does not scan for or store information about Bluetooth devices.

Crash reports: Blendy Translate sends anonymous crash reports (device model, operating system version, app version, and the technical details of the crash) to Firebase Crashlytics. They are on by default and can be switched off in Settings, Send crash reports.

Usage analytics: off until you agree. The app asks once, “Help improve the app?”, with “No” as the default, and you can change your choice in Settings at any time. If you agree, Firebase Analytics records anonymous events: the language pair and mode of a translation, whether it was offline, speech recognition error codes, language downloads, and onboarding steps. It never includes what you said or the text you translated. The app does not use an advertising ID.

Blendy Translate does not require an account, does not ask for your name or email, and does not show advertisements. The Firebase project used by Blendy Translate is separate from the one used by our other apps.

You are not required to provide your name, email address, or other personal details to use the Service. The content you create in the apps, such as trips, checklists, notes, links, and documents, is stored on your device.

To operate the Service, our servers handle a limited set of technical records:

• an anonymous account identifier created by Firebase Authentication
• your AI credit balance and a history of credit transactions
• a hashed device identifier used to prevent abuse of promotional credits
• technical records of AI requests: operation type, model used, token counts, cost, status, and timing
• when an AI request fails, the content of that request and of the response, kept to diagnose the problem

We do not use this information to identify you personally or to show you advertisements.

When you use an AI feature, the content of your request is sent from your device to our servers and from there to an AI provider that generates the response. This can include your message and the parts of your trips that are relevant to the request, such as destinations, routes, dates, names of travel companions, notes, and text from documents you have imported.

Our AI provider is Google (Gemini models, through the paid Gemini API or Google Cloud Vertex AI). Under Google’s terms for these paid services, your prompts and responses are not used to train or improve Google’s models or products, and Google processes them on our behalf under its Data Processing Addendum. Google may log requests for a limited period solely to detect abuse and meet legal obligations.

We may route requests to other AI providers that offer equivalent terms, such as Anthropic or OpenAI. We do not use providers or service tiers that use your content to train their models.

You can report an AI response from the chat if it is offensive, inaccurate, or unsafe. When you do, the reported response and the request that led to it are sent to us for review and deleted automatically after 14 days.

Please do not include sensitive information, such as passport numbers or payment card details, in AI requests. AI responses are generated automatically and may be inaccurate; verify visa, health, safety, and legal requirements with official sources.

Blendy Trips and Blendy Layers may display third‑party advertisements. Advertising partners (such as Google AdMob or other ad networks) may automatically collect certain information to deliver, personalize, and measure ads.

This information may include:

• device identifiers
• coarse location (e.g., country or region)
• app interactions
• IP address (processed by the ad network)
• advertising performance data

Our apps do not have access to this data and do not attempt to identify individual users. Data collection and processing are handled solely by the advertising partners in accordance with their own privacy policies.

You can learn more about how Google uses data for advertising in their Privacy Policy. To understand how Google processes data when you use our apps, please review Google’s Business Data Responsibility Site.

The apps use trusted third-party services to run the Service, monitor performance, improve app stability, and manage in-app purchases. Blendy Translate uses only Firebase Crashlytics and, with your consent, Firebase Analytics, as described in its section above:

• Firebase Authentication, Cloud Functions, Firestore, Remote Config, and App Check (Google): These services provide the anonymous account, run the AI proxy, store your credit balance and technical request records, and verify that requests come from a genuine app installation.
• Firebase Analytics & Firebase Crashlytics: These services may automatically collect limited technical information, including device type, operating system, app version, anonymous usage events, crash logs, diagnostics data, approximate location (country-level), and IP address. This data is processed by Google in accordance with their privacy policy and is used solely to fix errors and improve the quality of the Service.
• RevenueCat: This service is used to process and manage in-app purchases and subscriptions. It may collect anonymous transaction details and device identifiers to validate purchase states. RevenueCat does not collect your name, banking information, or credit card details.

These services operate independently from advertising partners and do not use your data for ad personalization within our apps.

If you are located in the European Union, our legal basis for processing the content of your AI requests is the performance of the Service you ask for, and our legal basis for processing the technical data described above, including the content of failed requests kept for diagnosis, is our legitimate interest in maintaining, improving, and securing the Service.

Under the General Data Protection Regulation (GDPR), you have the right to request access to your data, request deletion or restriction of processing, object to processing, and withdraw consent where applicable.

To exercise these rights, please contact us using the information provided in the Contact Us section.

Technical records of AI requests are deleted automatically after 14 days. Your credit balance and transaction history are kept while your anonymous account exists. Data collected by Firebase and advertising partners is retained in accordance with their respective data retention policies.

If an AI request fails, we keep the content of that request, such as your message and the trip details sent with it, and the response, if there was one, for up to 14 days so that we can diagnose and fix the problem. We do not keep the content of requests that succeed. Content sent to an AI provider is handled under that provider’s terms described above.

You can delete the data we hold about your account at any time in the app: Settings, Delete my data. This removes your anonymous account, your credit balance and history, and the records of your AI requests. Content of failed requests kept for diagnosis is not removed at that moment and is deleted automatically within 14 days. A one-way hashed device identifier is kept afterwards so that free credits cannot be claimed twice. Deleting your data does not cancel a subscription; you cancel it in the App Store or Google Play. While a subscription is active, or if you bought an unlock, we keep a minimal record of it: the plan, its dates, and the unlocks, without your credits or request history. It lets you restore the purchase on a new account and is deleted 30 days after the subscription ends, or after one year for unlocks. Purchase records are kept by Apple, Google, and RevenueCat as required for accounting. You can also contact us using the information in the Contact Us section.

Our services are not directed to children under the age of 13 (or 16 in the EU). We do not knowingly collect personal information from children. If you are a parent or guardian and become aware that your child has provided us with personal information, please contact us.

The mobile applications do not use cookies. If you access our website, basic technical cookies may be used to ensure proper functionality. We do not use cookies for advertising or cross-site tracking.

We may update this Privacy Policy from time to time. Any changes will be posted on this page.
