Privacy Policy

Last updated: November 10, 2026

This is an English translation of our Política de privacidad, provided for convenience. If the two versions differ, the Spanish version prevails.

In short: we use your data only to make Althia work. We do not sell it, we do not show ads, and we do not use analytics or tracking tools.

1. Who is responsible

Adherllys Meléndez García (trade name: Althia), Las Terrenas, Samaná, Dominican Republic. Privacy contact: soporte@althiaedu.com.

2. What data we process

• Your account: name, email, profile photo (if you add one) and sign-in data.
• Your work: classes, students and the academic data you record (for example, grades or attendance), lesson plans, materials, documents, audio and files you upload, and your conversations with Althia. If you fill in a student's record or file, also what you write there (family, health, learning and behavior information).
• Usage: how much you use the artificial intelligence and the voice, to apply your plan's limits and control costs; and technical error and security logs.
• Payment: the status of your subscription (active or not, dates and Paddle identifier). Your card and billing details are handled by Paddle: Althia never sees your card.

3. What we use it for

To provide the service, store and sync your work across your devices, generate what you ask the artificial intelligence for, apply usage limits, keep the service secure, answer your questions and charge your subscription. Nothing else.

Legal basis for each use

• Providing the service and charging your subscription: the contract you accept when you use Althia.
• Security, usage limits and cost control: our legitimate interest in a secure and sustainable service.
• Payment records: the legal obligation to keep them.
• Connecting «Mis nubes» (My clouds) or saving your files in your Google Drive: your consent, which you can withdraw at any time.

4. Who we share it with

With the services that make Althia work, each one only with what it needs for its function:

• Google (Firebase and Google Cloud): sign-in, your account's database and files, and the app's technical error log (the error message and the screen where it happened, without your content, without your email and without your students' data).
• Anthropic (Claude): receives the text of what you ask the artificial intelligence and the context needed to answer. If your request includes your students' data, it receives that too.
• Google (Gemini): only turns into speech the sentences Althia reads aloud.
• Groq or Cloudflare: turn into text the audio you record or attach (when your device can do it by itself, the audio does not leave it).
• Free image libraries (Wikimedia Commons, Openverse, iNaturalist, NASA and the Art Institute of Chicago, Cleveland and Metropolitan museums): receive the topic you search for. Images load from them, so, like any website, they see your connection's address. They do not receive your account or your students' data.
• Wikipedia, Vikidia and Wikibooks: queries about the topic you are working on. They do not receive your students' data.
• Paddle.com, our reseller and Merchant of Record: processes the payment and your billing details (name, email, country and payment details) as an independent controller, under its privacy policy.
• Professional advisers and authorities: only when the law requires it.

We choose artificial intelligence services whose terms for API customers state that they do not use that information to train their models. Some of these services are outside the Dominican Republic (for example, in the United States), so your data may be stored or processed there, with those providers' contractual safeguards.

Your Google Drive and OneDrive files («Mis nubes», My clouds)

If you connect a Google or Microsoft account in «Mis nubes», Althia asks only for what it needs to bring in the files you choose:

• Google: your name and email (to show which account you connected) and the drive.file permission, which gives access only to the files you pick in Google's file picker. Althia does not see the rest of your Drive.
• Your files in your Google Drive (optional): if you choose to keep your photos, evidence and documents there, Althia asks for the drive.appdata permission, which only gives access to a private Althia folder inside your Drive (you do not see that folder in Drive and Althia does not see the rest). Files go directly between your device and your Drive; Althia only stores which file is where.
• Microsoft: your name and email, and read permission for your OneDrive files to show you your folders and bring in the ones you choose.
• The chosen file is brought to your device and Althia treats it like one you upload yourself (for example, so the artificial intelligence can read it if you ask). Access permissions are kept only while the tab is open; your device keeps the list of connected accounts (name and email), which you can remove at any time from «Mis nubes». You can also revoke the permission in your Google or Microsoft account.
• Althia's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. That data is not sold, is not used for advertising or to train artificial intelligence models, and no person reads it.

5. Your students' data

Althia is for adult teachers. Students do not use the app. You record students' data under your responsibility and your school's, and Althia uses it only to help you with your work. We recommend not including more personal data than necessary in your requests to the artificial intelligence.

The student's official record (ID document, birth certificate, address, phone numbers) is not sent to the artificial intelligence. The only exception is when you ask Althia to read a photo, a document or a text to fill it in: then the artificial intelligence receives only what you upload, to read it, and does not receive the enrollment list or the records you already have saved; anything that is not clearly about a given student is not filled in. The notes in a student's file (family, health, learning and incidents) are passed to it in summary only when you ask Althia to look at your class or to write a report about that student, so it can take them into account; you decide what to write, and you can delete any note at any time.

6. How we protect it

• All communication is encrypted (HTTPS).
• No other account can read or change your data: the database rules prevent it. Althia's administrator sees only what is needed for support and cost control: your name, your email, your sign-in dates, your usage and the list of your files in the cloud (name, size and date), never their content or your academic data. They see it from a private panel that only Althia's owner can enter, with their Google account and two-step verification, and every time they look at or act on your account, it is logged.
• Payments and their records are handled only by the server, never by the browser.

7. Storage on your device

Althia keeps a copy of your work on your device (browser or app storage) so it works offline. We do not use advertising or tracking cookies.

8. How long we keep it

As long as you have your account. If you delete it, we erase your data from our servers within 30 days at most. We only keep what the law requires us to keep about payments (dates and amounts), without your content. Technical logs are deleted automatically over time.

9. Your rights

Under Dominican Law 172-13 on personal data protection, you can ask us to access, correct or delete your data, or object to its use. If you live in another country, you also have the rights your law gives you (for example, the GDPR in Europe: access, rectification, erasure, objection, portability and filing a complaint with your data protection authority). Write to us at soporte@althiaedu.com; we reply within 30 days at most.

10. Deleting your account and your data

• From the app: Configuración → Legal y privacidad → Eliminar mi cuenta y mis datos (Settings → Legal and privacy → Delete my account and my data), and type ELIMINAR to confirm. It happens immediately: your subscription is cancelled (you are not charged again) and your account, your data and your files are deleted from our servers and from that device.
• By email: if you cannot sign in, write to soporte@althiaedu.com from your account's email, with the subject «Delete my account». We check that the request is yours and delete it within 30 days at most.
• We only keep the payment records the law requires (dates and amounts) and anonymous accounting records of artificial intelligence usage, without your content.
• If you used Althia on another device, you delete the copy left there by uninstalling the app or clearing the site data in that browser.

11. Changes

If we change this policy, we will notify you in the app before the changes apply.
