privacy policy

who we are

Matraca is a bilingual iOS keyboard app that translates while you type and keeps you practicing in real conversations. This policy explains how we handle your personal data when you use the app, the keyboard, and our website.

The entity behind Matraca is based in São Paulo (Brazil) and Lisbon (Portugal) and acts as the controller of the data described here. For anything privacy-related, reach us at contato@matraca.ai.

the keyboard and full access

This is the most important part, so no hedging. To translate while you type, the Matraca keyboard needs the "Full Access" permission that iOS requests when you install a third-party keyboard. We know that permission is scary, and it deserves an honest explanation.

When you grant Full Access and you're typing inside a Matraca translation field, the text you write is processed to produce the translation — partly on the device itself, and partly in our translation infrastructure when the language requires it. That processing exists for one reason only: to hand you the sentence back in the other language.

What we do NOT do, and never will:

• We do not log or store what you type in password fields, credit card fields, or any field iOS marks as secure — the keyboard is disabled in those contexts.
• We are not a keylogger: we do not silently capture everything you type in other apps outside of Matraca's translation flow.
• We do not sell, rent, or trade what you type. Your keystrokes are not a product.
• We do not use the content of your messages for targeted advertising.

Text sent for translation always travels encrypted and is used only to produce the response and run app features (like your practice history and streak). You can revoke Full Access at any time in iOS Settings — without it, the keyboard's translation features stop working.

what we collect

We collect the minimum needed to make the app work and improve it:

• Account data: the name or handle, email, and login credentials you provide when you create an account.
• Text processed for translation: the sentences you write in the translation flow, and their translations, tied to your account to power history and practice.
• Streak and social data: consecutive days, completed chapters, friend connections, and the friendly pressure that keeps the conversation going.
• Usage analytics: how you move through the app, which features you use, and error reports — aggregated wherever possible.
• Device data: model, iOS version, language, technical identifiers, and diagnostics.

how we use your data

We use your data to:

• Operate the keyboard and deliver translations while you type.
• Maintain your account, streak, chapters, and connections.
• Process subscriptions and payments.
• Improve the product, fix bugs, and understand what works.
• Send important service notices and, with your consent, product news.
• Comply with legal obligations and protect against fraud and abuse.

legal bases

We process your data on the basis of contract performance (delivering the app you signed up for), your consent (where applicable, such as marketing communications), our legitimate interests (security, product improvement, fraud prevention), and compliance with legal obligations. Under LGPD and GDPR, you can withdraw consent at any time.

third parties and processors

We don't work alone. To run Matraca, we share strictly necessary data with providers acting as processors, under contract and confidentiality obligations:

• Stripe — payment and subscription processing.
• Translation and cloud infrastructure — to process text and host the service securely.
• Analytics and error-reporting providers — to understand usage and stability.
• Apple — App Store distribution and, when you subscribe there, billing management.

We do not sell your personal data to anyone.

payments via stripe

Payments are processed by Stripe. Your card details are collected and handled directly by Stripe under PCI-DSS standards — Matraca does not store your full card number. We receive from Stripe only what we need to manage your subscription, such as payment status and the last digits of your card. Subscriptions made through the App Store are managed by Apple under its policies.

data retention

We keep your data while your account is active and for as long as needed for the purposes in this policy or required by law. When you delete your account, we remove or anonymize your personal data within a reasonable timeframe, except for what we must retain for legal, tax, or fraud-prevention obligations.

security

We use encryption in transit and at rest, access controls, and security practices proportionate to the risk to protect your data. No system is perfect, but we treat your data the way we'd want ours treated. If a significant incident occurs, we will notify you and the relevant authorities as required by law.

international transfers

Matraca operates between Brazil and the European Union, and our providers may process data in other countries. When we transfer data internationally, we apply the safeguards required by LGPD and GDPR, such as standard contractual clauses and adequacy checks.

your rights

Under LGPD and GDPR, you have the right to access, correct, update, port, and delete your data, as well as to object to or restrict certain processing and withdraw consent. To exercise any of these, write to contato@matraca.ai — we respond within the legal timeframes. You may also lodge a complaint with the competent data protection authority (ANPD in Brazil, or your EU supervisory authority).

children

Matraca is not made specifically for children, and we do not knowingly collect children's data without the consent required by law. If we learn we've collected data from someone below the permitted age without the necessary authorization, we'll delete or correct that data.

changes to this policy

This policy may change as the product evolves or the law changes. When a change is significant, we'll let you know in the app or by email and update the date at the top. Continuing to use Matraca after that means you agree to the current version.
