Privacy Notice

DEEP Technologies L.L.C., the company that operates Deep Learning (the site deeplearning.support and its phone and tablet apps), is responsible for your personal data. This notice is issued in accordance with the Ley Federal de Protección de Datos Personales en Posesión de los Particulares (Federal Law on Protection of Personal Data Held by Private Parties) and explains, in simple words, what data we use, what for, with whom we share it, and what you can do with it. For any questions or requests, write to us at team@deeplearning.support.

1. What data we use

• Your account: name, email, password (stored encrypted with a method that does not allow it to be read; we never see it), your major if you indicate it, your public username, your profile picture if you upload it, and your time zone.
• Sign in with Apple: if you choose this option, Apple provides us with an identifier of your Apple account, your email (or a private Apple relay email, if you choose so), and, the first time, your name. We never receive your Apple password.
• What you upload and write: books, PDFs, photos, notes, drawings, quizzes or exams from your teachers, your answers, your messages with Deeper (the assistant), and your study progress.
• What Deeper remembers about you: small notes about your study preferences (for example, what subjects you study or whether you prefer short explanations). You can view and delete them in Deeper whenever you want.
• Payments: the status of your plan and your purchases. Your card data is handled by Mercado Pago or your phone's app store; we do not see or store it.
• Notifications: if you accept them in the app, a device identifier to send you review reminders.
• Minimal technical data: the IP address and the type of browser or device, to keep your session open, show you your active sessions, and prevent abuse (for example, password guessing attempts).

We do not ask you for sensitive data. If you decide to write it in your notes (for example, health data from a clinical case), it is treated the same as the rest of your content: only to provide you the service.

2. What we use them for

Purposes necessary to provide you the service:

• Create and protect your account and log you in.
• Prepare your books and notes, create questions, exams, study paths, games and reviews, grade your answers, and save your progress.
• When available, have Deeper answer your questions, give you advice, and do for you what you ask (it always asks you to confirm first).
• Charge your plan and deliver what you purchased.
• Send you emails about your account (for example, to reset your password) and review reminders.
• Keep the service secure and running, and comply with legal obligations.

Purposes that are not necessary (you can refuse them without losing the service):

• Sending you news and promotions by email. You can unsubscribe using the link included in each email or by writing to us.
• Internal and anonymous statistics to improve Deep Learning (for example, which features are used most).

We do not sell your data, we do not use it for advertising, and we have no ads or third-party trackers. We also do not use your content to train artificial intelligence models.

3. Artificial intelligence

To create questions, explanations and corrections, read photos and PDFs, and for Deeper to answer you, we send to an AI provider only the necessary fragment of your content (for example, the page you are studying or your answer), without your email. We use one of these providers, depending on which is available at that time:

• OpenAI (United States).
• DeepSeek (People's Republic of China).
• Google Gemini (United States).
• Amazon Web Services, with the models available in Amazon Bedrock, such as those from DeepSeek and Anthropic (United States).

We use their business services (API). OpenAI, Amazon Bedrock, and the paid service of Google Gemini indicate in their terms that they do not use that data to train their models, although they may retain it for a limited time to prevent abuse. DeepSeek's terms for its direct service do not offer that same guarantee, and its privacy policy contemplates using data to improve its models. We never use your content to train models. To verify data we also consult public sources such as Wikipedia and PubMed, but only with the topic being searched, never with your data.

AI can make mistakes. Compare what it tells you with your textbooks and teachers, especially on health topics.

4. With whom it is shared (transfers)

Only with providers that help us give you the service, and each one receives only what is necessary for its task:

• AI providers: those in section 3.
• Mercado Pago (payments on the web).
• Apple, Google, and RevenueCat (in-app purchases, United States).
• Apple (Sign in with Apple and iPhone and iPad notifications) and Google Firebase (notification delivery), in the United States.
• Brevo (email delivery, European Union).
• The server hosting providers where your data is stored (Hostinger and Amazon Web Services).
• Authorities, only when required by law.

Some of these transfers are to other countries (United States, China, and the European Union). They are necessary to provide you with the service you request, so the law does not require your separate consent. Even so, you can object by writing to us.

What others see: only your username, your photo, and your points, in games. Your email is never shown. If you share an exam, a route, or a notebook, whoever receives it can see what you shared until you stop sharing it.

5. The phone and tablet app

• The app uses the same data as the web. It does not access your contacts, location, or microphone. It only uses the camera or your photos when you choose to upload one.
• Notifications are only activated if you accept them, and you can turn them off in your phone settings.
• We do not track you in apps or sites of other companies (on iPhone we do not request tracking permission).

6. Cookies and storage

We use a necessary cookie to keep your session open and your browser's storage to remember your preferences (for example, light or dark theme or pen colors). We do not use advertising or third-party analytics cookies.

7. Automated decisions

AI corrects your answers and suggests what to review. Those grades are for guidance and do not produce legal effects on you. If you disagree with a correction, you can request that a person review it by writing to us.

8. How long we keep them and how we protect them

• While you have your account. When you delete it, we erase your account, your files, and all your content immediately. Backup copies may retain them for a limited time before being deleted.
• Payment data is retained for the time required by tax laws.
• We protect your data with encrypted connection (HTTPS), encrypted passwords, service keys stored with encryption, separation of each account in the database (no one else can read your notes), and limits against abuse.
• If a security breach occurs that significantly affects your rights, we will notify you without delay so you can protect yourself.

9. Your rights

• Download your data: Settings → Data and account → Export data.
• Delete your account and all its content: Settings → Data and account → Delete account, also from the app. If you signed in with Apple, we also revoke Apple's access. If you pay with Apple or Google, also cancel the subscription in your store account.
• ARCO rights (access, rectification, cancellation and opposition), revoke your consent or limit the use of your data: write to us at team@deeplearning.support with your name, your account email and what you are requesting. We will respond within a maximum of 20 business days.
• If you are not satisfied with our response, in Mexico you can contact the Secretaría Anticorrupción y Buen Gobierno (Anti-Corruption and Good Government Secretariat), the authority on personal data matters.

10. If you live outside Mexico

These rights are in addition to the previous ones and are exercised by writing to the same email:

• European Economic Area and United Kingdom: we process your data to fulfill the contract with you, for legitimate interest (security and service improvement), with your consent (promotional emails) or due to legal obligation. You can request access, rectification, deletion, limitation and portability, object to processing and withdraw your consent. You can also file a complaint with the data protection authority of your country.
• California and other U.S. states: you can request to know, correct and delete your data without receiving different treatment for doing so. We do not sell your data or share it for targeted advertising.
• Brazil, China, India and other countries: we respond to you in accordance with the rights recognized by the law of your country, including information about the international transfers in section 4.

11. Minors

Deep Learning is not intended for children under 13 years of age, or the minimum age required by the law of your country if it is higher. If you are a minor, use Deep Learning with permission from your mother, father or guardian. If you are a mother, father or guardian and want us to delete a minor's data, write to us.

12. Changes to this notice

If we change this notice, we will update the date above and, if the change is significant, we will notify you by email or within the app.

This notice may be read in several languages. The translations are provided as a courtesy: if there is any difference, the Spanish version prevails, unless the law of your country provides otherwise.
