Curva Direta — Privacy Policy

Who is responsible for your data

This privacy policy explains how Curva Direta collects, uses and protects your personal data. The data controller is:

This policy applies only to Curva Direta. Our other apps have their own policies, available at rochalabs.pro.

Data we collect: none on our servers

Curva Direta was designed to work entirely on your device. It does not require an account, and the simulations you run — amounts, dates, rates and scenarios — are stored only in the app's local storage on your phone. We do not operate a server that receives, stores or processes this information.

If you delete the app, its data is deleted with it. Standard device backups (iCloud on iOS, Google backup on Android) may include the app's data under the platform's own terms, which you control in your device settings.

What we do NOT collect

• No government identifiers — we never ask for CPF, RG, passport or any ID document.
• No access to your contacts, camera, microphone, photos or location.
• No credit card numbers — payments are processed entirely by Apple, Google or our payment processor; card data never reaches our servers.
• No browsing history or data from other apps.

Third parties

Curva Direta has no analytics or cloud providers, and your content never reaches any server of ours. Two third parties are still involved in running the app:

How long we keep your data

Because we do not store your data on any server, there is nothing for us to retain or delete: all data stays on your device and is removed when you delete the app.

Advertising

Curva Direta shows ads served by Google AdMob — they are what keeps the app free.

To serve and measure ads, Google may process technical identifiers of your device (such as the advertising identifier). On iOS, cross-app tracking only happens if you allow it in the App Tracking Transparency prompt; on Android, you can reset or delete your advertising ID in the system settings. If you decline, ads are still shown, just less personalized. We do not give Google your name, your email or the content you keep in the app.

If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent before showing personalized ads, using a consent management platform certified by Google. You can review or change that choice at any time in the app settings.

Google explains how it uses data from apps and sites that show its ads at policies.google.com/technologies/ads, and its privacy policy is at policies.google.com/privacy.

Your rights

Under the LGPD (Lei Geral de Proteção de Dados, Lei nº 13.709/2018), you have the right to:

• confirm whether we process your personal data;
• access the data we hold about you;
• correct incomplete, inaccurate or outdated data;
• request anonymization, blocking or deletion of unnecessary or excessive data;
• receive your data in a portable format;
• delete personal data processed with your consent;
• know which third parties we share data with;
• revoke consent, where processing is based on consent;
• lodge a complaint with the ANPD (Autoridade Nacional de Proteção de Dados).

To exercise any of these rights, email hello@rochalabs.pro. We respond within the timeframes set by the LGPD.

If you are in the European Economic Area or the United Kingdom, you have equivalent rights under the GDPR/UK GDPR, including the rights of access, rectification, erasure, restriction, portability and objection, and the right to complain to your local supervisory authority. The legal bases described above (contract, legal obligation, legitimate interests) apply equally under the GDPR.

Deleting your data

Curva Direta does not have accounts. To erase all app data, delete the app from your device — everything it stored goes with it.

Children

Curva Direta is not directed at children under 13, and we do not knowingly collect personal data from children. If you believe a child has created an account or provided us personal data, contact hello@rochalabs.pro and we will delete it.

Security

Because your data never leaves your device, its security depends primarily on your device protections (passcode, Face ID, encryption), which we recommend keeping enabled.

Changes to this policy

We may update this policy to reflect changes in the app or in the law. The "Updated" date at the top always shows the current version. For material changes, we will notify you in the app or by email at least 15 days before they take effect. Continued use of Curva Direta after that date means you are aware of the updated policy.
