Privacy Policy

Last updated: August 10, 2026

1. Who we are

Houston is developed by Zentto. For privacy questions or requests, write to hello@houstonapp.space.

2. Data we process

• Account data, such as name, email, Apple or Google sign-in identifiers and profile picture when provided by the provider.
• Content created in the app, including tasks, reminders, lists, dates, categories, focus sessions and photos you choose.
• Text sent to the AI assistant. By default we log technical metadata and a hash of the text; raw content is only stored when that option is enabled in the service.
• Subscription and purchase data provided by Apple and processed by RevenueCat, such as the product purchased and the subscription status. We never receive your card number.
• Technical data required for security, diagnostics and running the service, such as IP address, crashes and performance.
• If you allow it on the website, Google Analytics collects browsing and device data, such as pages visited, interactions, browser and approximate location derived from the IP address. Analytics is not loaded before your consent.

3. How we use data

We use data to create and protect your account, sync content across installs, deliver reminders, process the AI features you request, recognize subscription benefits, provide support, prevent fraud and improve the reliability of the app.

4. Services that help us

We share only the necessary data with providers that operate parts of the service, such as Apple and Google for sign-in, Apple and RevenueCat for subscriptions, Google Analytics when you allow it on the website, infrastructure providers and AI providers configured by Houston. These providers process data under their own terms and contractual obligations.

5. Photos, notifications and on-device data

Access to the camera or photo library happens only after your choice and permission. Notifications and alarms are scheduled for the reminders you request. Some content is stored locally so the app can work and sync; it is removed from the device when you delete your account or sign out.

6. Retention and deletion

We keep data while your account is active or for as long as needed to provide the service and comply with legal obligations. You can delete your account inside the app under Menu → Delete my account. Deletion removes data linked to your account from active systems, except where limited retention is required by law, security or fraud prevention.

7. Your rights

You may request access, correction, portability, information about sharing, objection or deletion of data, as provided by applicable law, including Brazil's LGPD and, where applicable, the GDPR. Send your request to hello@houstonapp.space. We may ask you to confirm your identity.

8. Security and transfers

We adopt technical and organizational measures to protect data. Some providers may process it outside Brazil; in those cases we rely on the applicable legal mechanisms. No system is entirely free of risk.

9. Children

Houston is not directed to children under 13 and we do not knowingly collect data from children below that age.

10. Website, cookies and measurement

The Houston website uses strictly necessary local storage to remember your language and privacy preferences. With your permission, we use Google Analytics to measure visits and understand how the site is used. Google Analytics is not loaded before you accept. You can decline without losing any site feature and change your choice at any time through the “Cookies” link in the footer.

11. Changes

We may update this policy to reflect changes in the product or in the law. The date at the top indicates the current version; relevant changes will be communicated appropriately.
