Privacy policy
Last updated: September 15, 2026
NEXUS is an app for managing construction work: a company's calendar, tasks, supplies, invoices, quotes and payments, shared with its team. It is available to businesses in the United States, Mexico and other Latin American countries. NEXUS is provided by Erick Eduardo Marquez Alcala, based in Mexico. For any privacy matter, write to soporte@nenexus.app.
What data we use
- Your account: email address, name, language, time zone and preferences.
- Your company's data entered by you and your team: jobs, addresses, customers, services, tasks, notes, messages between members, supplies, invoices and payments.
- Photos and files you upload to a job, an extra or a delivery.
- Location, only while you use the app and only for the map, weather and delivery routes. Never in the background.
- Your device identifier, to send you notifications.
- If your company is in the United States and takes online payments, Stripe processes them. NEXUS does not store card or bank account numbers.
- Minimal technical logs for security and to fix errors.
What we use it for
We don't sell your data, we don't show ads and we don't track you across other apps or websites.
- Providing the service: showing and saving your company's information, notifying you of changes and sending the invoices and quotes your company issues.
- Protecting accounts and preventing abuse.
- Handling your support requests.
Who else processes it
We use providers that process data only to deliver the service, under their own security terms:
- Supabase: database, sign-in and file storage.
- Render: application server.
- Vercel: website and web console.
- Stripe: online invoice payments.
- Email providers: delivering account-access emails and invoices (through your company's own mail server, if it set one up).
- Expo and Apple: delivering notifications to your phone.
- Apple Maps: maps and address search, in the app and the web console. Google Maps is only used as a fallback in the console if Apple Maps isn't available.
- Apple WeatherKit: weather. Only the job's coordinates are sent.
- OpenAI: only to translate, into the customer's language, the message typed by hand in an invoice email. OpenAI does not store that text or use it to train its models. We don't use artificial intelligence with your data for anything else.
- Telegram: only if you link your account to receive notifications there.
Who sees your information inside NEXUS
A company's information is visible to its members according to the permissions set by that company's administrator. An administrator cannot see your conversations or personal reminders. No other company can see your data.
How long we keep it
While your account is active. If you ask to delete it, it stops working immediately and is kept for 30 days in case you change your mind; after that it is permanently deleted. Information that belongs to your company (jobs, invoices, payments) stays with the company, because it is theirs and they may have legal or tax obligations to keep it.
Your rights
If you live in the United States, you can ask us what personal data we have about you, get a copy, correct it or delete it, by writing to soporte@nenexus.app from your account's email address. We'll verify it's you and reply within 45 days at most. If you live in a state with its own privacy law (for example, California), you also have the rights that law gives you. We don't sell or share your data for advertising, and we won't treat you differently for exercising your rights.
You can delete your account yourself from the app or the web console: see the “Delete account” page.
If you live in Mexico or another Latin American country
The party responsible for your personal data is Erick Eduardo Marquez Alcala, based in Mexico; contact: soporte@nenexus.app. We process your data only for the purposes in this policy, which are necessary to provide the service; we don't use it for advertising or marketing.
You have the right to access, correct or delete your data, or object to its use (ARCO rights), and to withdraw your consent. Write to us from your account's email address saying which right you want to exercise; we'll verify it's you and reply within 20 business days at most. If you're not satisfied, you can contact the data protection authority in your country.
Your data is stored on servers in the United States, with the providers listed above. That transfer is necessary to provide the service, and those providers use the data only to deliver it.
Security
All communication is encrypted (HTTPS). Passwords are handled by the sign-in system and we never see them. Sensitive actions ask you to confirm your identity again. Each company's data is isolated from the others.
Children
NEXUS is a work tool and is not directed at anyone under 16.
Changes to this policy
If we change this policy, we update the date above and, if the change is significant, we let you know in the app.
