Who is responsible for your data

Mantiks is responsible for the personal data described in this policy.

If you have a question or want to exercise your privacy rights, contact us at hello@mantiks.ai.

Information we collect

Account information

When you create an account, we collect your email address.

If you sign in using Google or Apple, we may also receive the name and profile picture associated with that account, depending on the information you choose to share.

Authentication is provided by Clerk. Mantiks does not receive or store your password.

Learning content

We store the content you create and receive through Mantiks, including:

• conversations and messages;
• vocabulary and learning progress;
• lessons, quizzes, and readings;
• generated replies and exercises; and
• your app preferences and settings.

We need this information to provide the service and make your learning content available across sessions.

Attachments

If you choose to attach an image or document to a message, we upload and process that file.

On mobile devices, Mantiks requests access to your camera or photo library only when you use an attachment feature. Only the photos or files you choose are uploaded.

Waitlist information

If you join the waitlist on our website, we collect the email address you submit. We use it to contact you about Mantiks and the availability of the service.

Operational information

Our systems may automatically record limited technical information, including:

• IP address;
• date and time of a request;
• device, browser, or app information;
• request and error information; and
• security and authentication events.

We use this information to operate the service, troubleshoot problems, prevent abuse, and maintain security. We do not use it to build advertising profiles or track you across unrelated services.

What we do not do

Mantiks does not:

• sell or rent personal data;
• use your data for targeted advertising;
• include advertising networks or advertising identifiers;
• use analytics SDKs or tracking pixels;
• track your activity across other apps or websites;
• request access to your contacts; or
• collect precise location data.

Mantiks accesses your camera, photos, or files only when you choose to use a feature that requires them and grant the necessary permission.

How and why we use your information

We use personal data for the following purposes:

Providing Mantiks

We use your account information and learning content to sign you in, store your work, generate learning material, and provide the app’s features.

Where applicable under European data protection law, our legal basis is that this processing is necessary to perform our contract with you.

Operating and protecting the service

We use limited technical and operational information to diagnose errors, maintain availability, secure accounts, and prevent fraud or misuse.

Our legal basis is our legitimate interest in operating a reliable and secure service.

Managing the waitlist

We use a waitlist email address to provide the updates you requested. Our legal basis is your consent. You can withdraw that consent at any time by contacting us.

Meeting legal obligations

We may process or preserve information when reasonably necessary to comply with applicable law, respond to lawful requests, or establish, exercise, or defend legal claims.

AI processing

Mantiks uses Google’s Gemini models to generate replies, lessons, quizzes, readings, exercises, and spoken audio.

When you use these features, the material needed to respond to your request is sent to Google for processing. This may include:

• your message;
• relevant parts of your conversation or learning context;
• images or documents you attach; and
• instructions supplied by Mantiks to generate the response.

Google returns the generated result to Mantiks, and we may store that result in your account as part of your learning content.

This processing is an essential part of Mantiks. Do not submit confidential or sensitive information that you do not want processed by Google.

Google processes this information under the terms that apply to the Gemini service used by Mantiks.

Service providers

We use a small number of service providers:

• Clerk — account registration, authentication, and session management.
• Google Gemini — generating AI-powered replies, learning materials, exercises, and audio.
• Google Cloud Platform — hosting, databases, and private file storage.

These providers process personal data only to supply their services to us and are subject to contractual and legal obligations concerning data protection.

We may also disclose information if required by law, to protect the security or rights of Mantiks or others, or as part of a merger, acquisition, financing, or sale of the business. If ownership changes, personal data will remain subject to this policy unless you are notified otherwise.

Where data is processed

Our application servers, database, and file storage are hosted on Google Cloud in the European Union, in Belgium (europe-west1).

Some providers may process limited information in other countries. Where European data protection law requires it, such transfers must be covered by an approved legal safeguard, such as an adequacy decision or standard contractual clauses.

Storage and security

Data is transmitted using encrypted connections. Stored data is protected using the security measures provided by our hosting and service providers.

Attachments are kept in private storage and are not intended to be publicly accessible. When the app needs to display an attachment, it uses a time-limited signed link.

No online service can guarantee perfect security. We reduce risk by limiting the information we collect, restricting access, and using established infrastructure providers.

How long we keep information

We generally keep your account information and learning content for as long as your Mantiks account remains active.

Operational logs are retained only for the period reasonably needed for security, troubleshooting, and service operation, according to our configuration and our providers’ retention schedules.

Waitlist email addresses are kept until the waitlist is closed, you unsubscribe, or you ask us to delete your address.

We may retain limited information for longer when required by law, needed to resolve a dispute, or necessary to protect the service from fraud or abuse.

Deleting your account

You can delete your account from inside the Mantiks app. On mobile, the option is in the sidebar next to Sign out.

Account deletion removes your account and the associated information held in Mantiks’s active systems, including:

• conversations and messages;
• vocabulary and learning progress;
• lessons, quizzes, and readings;
• preferences and settings;
• uploaded attachments; and
• your authentication account.

Deletion is permanent and cannot be undone. Export anything you want to keep before deleting your account.

Deletion from active systems begins when you confirm the request. Limited copies may remain temporarily in encrypted backups or security records until they expire through normal retention cycles. We may also retain information where the law requires or permits us to do so.

Deleting your Mantiks account does not delete your separate Google or Apple account.

Your privacy rights

Depending on where you live, you may have the right to:

• ask what personal data we hold about you;
• receive a copy of your data;
• correct inaccurate information;
• ask us to delete your information;
• restrict or object to certain processing;
• receive certain information in a portable format; and
• withdraw consent where we rely on consent.

You can delete your account directly in the app. For other requests, email hello@mantiks.ai. We may need to verify that the request relates to your account before acting on it.

If you are in the European Economic Area or the United Kingdom, you may also complain to your local data protection authority. We would appreciate the opportunity to address your concern first, but you are not required to contact us before making a complaint.

Children

Mantiks is not directed to children under 13, and we do not knowingly collect personal data from them.

If you believe that a child under 13 has created an account or submitted personal information, contact hello@mantiks.ai and we will investigate and delete the information where appropriate.

Users must also meet any higher minimum age required to consent to online services in their country, unless a parent or legal guardian has provided valid permission.

Changes to this policy

We may update this policy when Mantiks, our service providers, or applicable legal requirements change.

We will update the date at the top of this page. If a change materially affects how we use personal data, we will provide additional notice in the app, on our website, or by email.
