Privacy Policy – LingoAI Keyboard

1.Who We Are

Controller / Service Provider

LingoAI Keyboard is provided by:

ZephyrFuture Inc.
Email: hey@zephyrfuture.com

If you have any questions about this Privacy Policy or our data practices, you can contact us at the email above.

2.Scope of This Policy

This Privacy Policy applies to:

• The LingoAI Keyboard input method (IME) on iOS and Android;
• Any companion or host app associated with LingoAI Keyboard;
• Any websites or online pages operated by ZephyrFuture that link to this Privacy Policy.

This Privacy Policy does not apply to:

• Third-party applications, services, or websites that you access while using our keyboard (for example, messaging apps, browsers, or other apps where you type);
• Third-party keyboards or system keyboards provided by device manufacturers.

Those third parties have their own privacy policies, and we encourage you to read them carefully.

3.Information We Collect

Our design principle is data minimization: we only collect the information necessary to provide and improve LingoAI Keyboard’s language learning features.

3.1 Information you type using LingoAI Keyboard

By default, LingoAI Keyboard processes your keystrokes on your device in order to provide core keyboard and language-learning features (such as suggestions or vocabulary prompts).

Depending on your settings and your use of the Services, we may process the following information:

• Text you type in supported apps and fields, for the limited purposes of:
  • generating word suggestions and corrections,
  • providing real-time language learning prompts (for example, vocabulary cards or phrase suggestions),
  • improving on-device models (where supported).
• Metadata about typing such as language, word length, the time of input, and the app in which the word was entered, in order to understand usage patterns and improve predictions.

Unless explicitly stated otherwise in this Policy or within the product:

• We do not intentionally collect or store passwords, credit card numbers, or other highly sensitive credentials.
• We do not attempt to read text from fields that the operating system designates as secure or sensitive (for example, password fields, payment fields), following best-effort industry practices.

Please note that, as with other third-party keyboards, the operating system may display a generic warning that the keyboard “can access all the text you type”. This does not mean we record everything you type; it reflects the technical capabilities of keyboards in general.

In some cases, we may temporarily process specific text on our servers to provide advanced features (for example, cloud-based language analysis or AI suggestions), but only when you explicitly enable such features or send a request to our servers.

3.2 Account and profile information

If you create a LingoAI or ZephyrFuture account, we may collect:

• Email address or other login identifiers;
• Display name, avatar, or profile information you choose to provide;
• Subscription and billing information (managed via the App Store, Google Play, or other payment providers);
• Your language learning preferences (for example, native language, target language, proficiency level).

3.3 Device and usage information

When you use our Services, we may automatically collect:

• Device information: device model, operating system version, app version, language and region settings;
• Technical identifiers: randomly generated installation IDs, analytics IDs, and similar identifiers;
• Usage information: which features you use, how often you use the keyboard, crash logs, and performance data.

We use this information to:

• Maintain and improve the stability and security of the Services;
• Analyze aggregate usage trends;
• Diagnose bugs and crashes;
• Plan new features and enhancements.

3.4 Cookies and similar technologies

If you access our websites, we may use cookies and similar technologies for:

• remembering your preferences;
• measuring website traffic;
• improving our website experience.

Where required by applicable law, we will obtain your consent before setting cookies that are not strictly necessary.

4.How We Use Your Information

We use the information we collect for the following purposes:

1. To provide the Services
   • Enable you to use LingoAI Keyboard for text input;
   • Provide word predictions, spell checking, and language learning suggestions;
   • Synchronize your settings across devices (if you sign in and enable sync).
2. To improve and personalize the Services
   • Train and refine our language models to give you better suggestions and more relevant vocabulary prompts;
   • Personalize the difficulty level, topics, and content of your language exercises.
3. To maintain security and prevent abuse
   • Detect and prevent spam, abuse, or security incidents;
   • Protect the integrity of our systems and Services.
4. To provide customer support
   • Respond to your inquiries and support requests;
   • Investigate and resolve technical issues or complaints.
5. To comply with legal obligations
   • Respond to lawful requests from authorities where required by applicable law;
   • Enforce our terms, policies, and legal rights.

Where required by applicable law (for example, in the European Economic Area or the United Kingdom), we rely on legal bases such as performance of a contract, legitimate interests, and consent (where required) for specific processing activities.

5.Sensitive Information

We recognize that keyboard apps can, in theory, access sensitive data. Our design seeks to minimize this risk:

• We do not intentionally log or store passwords, credit card numbers, or similar payment data.
• We follow best-effort practices to avoid or exclude sensitive input fields.
• We encourage app developers to use secure input fields (for example, password fields) so that third-party keyboards, including ours, cannot access that content.

Despite these protections, we cannot fully control how third-party apps implement their input fields. For maximum security, you may choose to switch to the system keyboard when entering highly sensitive data.

6.Data Processing Location, Storage, and Retention

LingoAI Keyboard is primarily designed to process data on your device whenever possible.

If and when certain features require cloud processing (for example, AI-based language feedback or cross-device sync), we may temporarily send relevant text and associated metadata to our servers or to trusted service providers for the limited purpose of fulfilling your request.

We retain personal data:

• Only for as long as necessary to provide the Services and for the purposes described in this Policy;
• For longer periods where required by law, dispute resolution, or enforcement of our agreements.

When data is no longer needed, we will delete it or anonymize it in accordance with our standard data retention policies.

7.How We Share Your Information

We do not sell your personal data.

We may share information in the following limited circumstances:

7.1 Service providers

We may share information with trusted third-party vendors that help us operate the Services, such as:

• cloud hosting providers;
• analytics and crash reporting services;
• customer support tools;
• payment processors (including the App Store and Google Play).

These providers are authorized to use your information only as necessary to provide services to us and are bound by confidentiality obligations.

7.2 Business transfers

In connection with a merger, acquisition, financing, or sale of all or a portion of our business, your information may be transferred as part of that transaction, subject to standard confidentiality protections and applicable law.

7.3 Legal compliance and protection

We may disclose information if we believe, in good faith, that such disclosure is reasonably necessary to:

• comply with any applicable law, regulation, legal process, or governmental request;
• enforce our terms and policies;
• protect the rights, property, or safety of ZephyrFuture, our users, or the public.

7.4 With your consent

We may share information for other purposes if you expressly consent to such sharing.

8.International Data Transfers

Depending on your location, your information may be transferred to and processed in the United States, as well as other countries or jurisdictions where we or our trusted service providers operate. These locations may have data protection laws that are different from those in your country.

Where required by applicable law, we implement appropriate safeguards—such as Standard Contractual Clauses or other lawful transfer mechanisms—to protect your information when it is transferred internationally.

9.Your Rights and Choices

Depending on your jurisdiction, you may have some or all of the following rights regarding your personal data:

• Access – request access to the personal data we hold about you;
• Correction – request correction of inaccurate or incomplete personal data;
• Deletion – request deletion of your personal data, subject to legal limitations;
• Restriction – request that we restrict certain processing activities;
• Objection – object to processing based on our legitimate interests;
• Portability – request to receive your data in a structured, commonly used, and machine-readable format, where technically feasible;
• Withdrawal of consent – where processing is based on consent, you may withdraw consent at any time without affecting the lawfulness of processing before withdrawal.

You can exercise these rights by:

• Using in-app settings to manage your privacy and data preferences, where available; or
• Contacting us at hey@zephyrfuture.com.

If you are in the European Economic Area, the United Kingdom, or another jurisdiction with data protection authorities, you also have the right to lodge a complaint with a supervisory authority.

10.Your Choices in the Product

Within LingoAI Keyboard and its companion app, you may have the following controls (where implemented):

• Enable or disable cloud-based features, such as online suggestions or sync;
• Clear local learning data (for example, reset personal dictionary or learning history);
• Opt in or out of analytics or diagnostic data sharing, where such options are provided;
• Switch keyboards at any time or remove LingoAI Keyboard from your system settings.

On iOS, you may also choose whether to grant “Full Access” to the keyboard extension. Some advanced features may not be available without Full Access, but the keyboard can still function in a more limited, privacy-preserving mode.

11.Children’s Privacy

Our Services are not directed to children under 13 (or a higher age threshold where required by local law). We do not knowingly collect personal data from children under this age.

If we become aware that we have collected personal data from a child in violation of applicable law, we will take steps to delete such information as soon as reasonably practicable.

If you believe a child has provided us with personal data, please contact us at hey@zephyrfuture.com.

12.Security

We take reasonable and appropriate technical and organizational measures to protect your personal data from accidental or unlawful destruction, loss, alteration, unauthorized access, or disclosure. These measures may include:

• Encryption in transit where appropriate;
• Access controls and authentication;
• Regular security reviews and monitoring.

However, no method of transmission over the internet or electronic storage is 100% secure. We cannot guarantee absolute security.

13.Third-Party Links and Services

Our Services may include links to third-party websites, services, or content. We are not responsible for the privacy practices of those third parties.

We encourage you to read the privacy policies of any third-party services you access.

14.Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our Services, legal requirements, or data practices.

When we make material changes, we will:

• Update the “Last updated” date at the top of this Policy; and
• Notify you through the app, by email, or by other appropriate means, where required by law.

Your continued use of the Services after the effective date of the updated Policy constitutes your acceptance of the changes.
