Privacy notice
Last updated: 25 October 2026. Aletheia is in early testing. This notice explains what we collect, why, and what you can ask us to do with it.
Who is responsible
Antonio Gustavo Lozano Sánchez (Aletheia), Tax ID (NIF) 23.803.102-B, Cmno. de Gelibra s/n, 18690 Almuñécar, Granada, Spain. Email: admin@aletheia.college.
What we collect and why
| Data | Why | Legal basis | How long |
|---|---|---|---|
| Your email, the language of the page and, optionally, what you'd use Aletheia for, when you join the waitlist | To tell you when early access opens | Your consent | Until you ask us to remove it, or 12 months after launch |
| Your email (and your name, if you sign in with Google) | To create your account and let you sign in | Providing the service you asked for | Until you delete your account |
| If you turn on fingerprint or face sign-in: a public key for each device, its name and when it was last used. Your fingerprint, face or PIN never leave your device; we never receive them. | To let you sign in without an email link | Providing the service you asked for | Until you remove the device or delete your account |
| The text of your spoken answers, their timing, and your results | To give you feedback, keep your progress and limit free use to one session a day | Providing the service you asked for | Until you delete your account |
| Technical logs: IP address, time and type of request | To keep the service secure and fix errors | Our legitimate interest in security | 30 days |
We don't sell your data, show ads or use your answers to train AI models. Don't share health details or information about other people in your answers; the exercises don't need them.
Your voice
Your voice is turned into text by your browser's own speech service (Google in Chrome, Microsoft in Edge), under that company's terms. We receive only the text, never the audio. The microphone is on only while you're answering.
Who else handles your data
- Hetzner Online hosts our servers in Helsinki, Finland (EU).
- Resend sends our sign-in emails. It is based in the United States and works under the EU Standard Contractual Clauses.
- Google receives your sign-in request only if you choose “Continue with Google”.
Cookies and browser storage
We use one cookie to keep you signed in, and a short-lived one while you sign in with Google. Both are strictly necessary, so we don't ask for consent. We use no analytics or advertising cookies, and our fonts are served from our own server. Your browser also stores your language, your practice preferences (like silent mode) and a random device code that we receive with your practice results; none of it is used for advertising.
Your rights
You can ask us to access, correct, delete or export your data, to restrict or object to how we use it, and you can withdraw your consent at any time. Write to admin@aletheia.college and we'll reply within one month. If you're not satisfied, you can complain to the Spanish data protection authority (aepd.es) or the one in your country.
Age
Aletheia is for people aged 16 and over.
